James Hansen, head of NASA's GISS and technical adviser on An Inconvenient Truth, wrote recently

Thus there is no need to equivocate about the summer heat waves in Texas in 2011 and Moscow in 2010, which exceeded 3σ – it is nearly certain that they would not have occurred in the absence of global warming. If global warming is not slowed from its current pace, by mid-century 3σ events will be the new norm and 5σ events will be common.

This statement alone should be enough for any thoughtful person who here-to-fore has bought in to global warming hysteria out of vague respect for "science" to question their beliefs.

First, he is basically arguing that a 3σ event proves (makes it "nearly certain") that some shift has occurred in the underlying process.  In particular, he is arguing that one single sample's value is due to a mean shift in the system.  I don't have a ton of experience in process control and quality, but my gut feel is that a 3σ event can be just that, a 3σ event.  One should expect a 3σ event to occur, on average, once in every 300 samples of a system with a normal distribution of outcomes.

Second, and a much bigger problem, is that Hansen is gaming the sampling process.  First, he is picking an isolated period.  Let's say, to be generous, that this 3σ event stretched over 3 months and was unprecedented in the last century.  But there are 400 3-month periods in the last hundred years.  So he is saying in these two locations there was a 3σ temperature excursion once out of 400 samples.  Uh, ok.  Pretty much what one would expect.

Or, if you don't like the historic approach, lets focus on just this year.  He treats Moscow and Texas like they are the only places being sampled, but in fact they are two of hundreds or even thousands of places on Earth.  Since he does not focus on any of the others, we can assume these are the only two that have so-called 3σ temperature events this summer.

It's hard to know how large to define "Texas"  (since the high temperatures did not cover the whole state) or "Moscow" (since clearly the high temperatures likely reached beyond the suburbs of just that city).

Let's say that the 3σ event occurred in a circular area 500km in diameter.  That is an area of 196,250 sq km each.  But the land surface area of the Earth (we will leave out the oceans for now since heat waves there don't tend to make the headlines) is about 150 million sq km.   This means that each of these areas represent about 1/764th of the land surface area of the Earth.  Or said another way, this summer there were 764 500km diameter land areas we could sample, and 2 had 3σ events.  Again, exactly as expected.

In other words, Hansen's that something unusual is going on in the system is that he found two 3σ events that happened once every 300 or 400 samples.  You feeling better about the science yet?

Luboš Motl has a more sophisticated discussion of the same statement, and gets into other issues with Hansen's statement.

Postscript:  One other issue -- the mean shift in temperatures over the last 30 years has been, at most, about 0.5C  (a small number compared to the Moscow temperature excursion from the norm).  Applying that new mean and the historic standard deviation, my guess is that the Moscow event would have still been a 2.5σ event.  So its not clear how an event that would have been unlikely even with global warming but slightly more unlikely without global warming tells us much of anything about changes in the underlying system, or how Hansen could possible assign blame for the even with near certainty to anthropogenic CO2.

This is really sad to see in what is supposed to be a liberal democracy:

Now that the carbon tax has passed through [Australian] federal parliament, the government’s clean-up brigade is getting into the swing by trying to erase any dissent against the jobs-destroying legislation.

On cue comes the Australian Competition and Consumer Commission, which this week issued warnings to businesses that they will face whopping fines of up to $1.1m if they blame the carbon tax for price rises.

It says it has been “directed by the Australian government to undertake a compliance and enforcement role in relation to claims made about the impact of a carbon price.”

...

There will be 23 carbon cops roaming the streets doing snap audits of businesses that “choose to link your price increases to a carbon price”.

Instead, the ACCC suggests you tell customers you’ve raised prices because “the overall cost of running (your) business has increased”.

Update:  Obama loves the Aussie carbon tax

Addressing the press in Australia, where legislators passed a carbon tax earlier this month, Obama praised Prime Minister Julia Gillard for pursuing “a bold strategy” to trim industrial emissions that most scientists say are contributing to global warming.

For those who have read my climate work or seen the video, the key question in climate science revolves around the feedback effects in the climate system to Co2 warming.

Skeptics, like alarmists, generally agree that a doubling of Co2 concentrations might warm the Earth about a degree Celsius, absent any other effects.  But we can imagine all sorts of feedback effects, the most important of which are in water vapor and cloud formation.  Warming that forms more clouds might have negative feedback, as clouds offset some of the warming.  Warming that increases humidity could lead to more warming, as water vapor is a strong greenhouse gas.

The difference, then, between minor warming and catastrophe is in the feedbacks, and most importantly in clouds and water vapor.  All the research the government is funding on whether warming will cause sterility in tree frogs is tangential to this key question.

And this question is far from decided.  I won't get into all the arguments here, but to the extent there is any consensus, it is that man' CO2 is probably causing some warming.  Whether this is a catastrophe or a nuisance depends on feedbacks which are not well understood.

This week there has been a lot of interesting back and forth over a paper by Roy Spencer several months ago arguing that cloud feedback was negative and would serve to limit the total amount of man-made warming.  Just how central this issue is can be seen in the fuss this paper has caused, including editors forced to resign for even daring to publish such heresy, and the speed with which a counter-paper flew through peer review.

I won't get into the depths of this, except to show two charts.  The first is from Dessler in the alarmist camp, the second is the same chart but using a different data series.  I won't explain the axes,  just trust the relationship between these two variables is key to diagnosing the size and direction of feedback.

So we get opposite results (the slope of the regression) simply by using temperature and radiative flux data from to different agencies.  And note how thin the fit is in both -- basically drawing a line through a cloud.  Neither of these likely has an R-squared higher than about .05.

So there you have it, the most important question in climate - really, the only important question associated with anthropogenic global warming.  Settled science, indeed.

here.

It's a wonder how, when over "97 percent to 98 percent" of scientific authorities accepted the Ptolomeic view of the solar system that we ever got past that.  Though I could certainly understand why in the current economy a die-hard Keynesian might be urging an appeal to authority rather than thinking for oneself.

When, by the way, did the children of the sixties not only lose, but reverse their anti-authoritarian streak?

Postscript:  I have always really hated the nose-counting approach to measuring the accuracy of a scientific hypothesis.  If we want to label something as anti-science, how about using straw polls of scientists as a substitute for fact-based arguments?

Yes indeed, the number of people in the newly made-up profession of "climate science" that are allowed by the UN control the content of the IPCC reports and whose funding is dependent on global warming being scary probably is very high.  The number of people in traditional scientific fields like physics, geology, chemistry, oceanography and meteorology who never-the-less study climate related topics that wholeheartedly are all-in for catastrophic man-made global warming theory would be very different

 Decide for yourself - see my video on global warming.  Am I anti-science?

Today in Forbes, I have an article bringing the layman up to speed on Henrik Svensmark and this theory of cosmic ray cloud seeding.  Since his theory helped explain some 20th century warming via natural effects rather than anthropogenic ones, he and fellow researchers have face an uphill climb even getting funding to test his hypothesis.  But today, CERN in Geneva has released study results confirming most of Svensmark's hypothesis, though crucially, it is impossible to infer from this work how much of 20th century temperature changes can be traced to the effect (this is the same problem global warming alarmists face -- CO2 greenhouse warming can be demonstrated in a lab, but its hard to figure out its actual effect in a complex climate system).

From the article:

Much of the debate revolves around the  role of the sun, and though holding opposing positions, both skeptics and alarmists have had good points in the debate.  Skeptics have argued that it is absurd to downplay the role of the sun, as it is the energy source driving the entire climate system.  Michael Mann notwithstanding, there is good evidence that unusually cold periods have been recorded in times of reduced solar activity, and that the warming of the second half of the 20th century has coincided with a series of unusually strong solar cycles.

Global warming advocates have responded, in turn, that while the sun has indeed been more active in the last half of the century, the actual percentage change in solar irradiance is tiny, and hardly seems large enough to explain measured increases in temperatures and ocean heat content.

And thus the debate stood, until a Danish scientist named Henrik Svensmark suggested something outrageous -- that cosmic rays might seed cloud formation.  The implications, if true, had potentially enormous implications for the debate about natural causes of warming.

When the sun is very active, it can be thought of as pushing away cosmic rays from the Earth, reducing their incidence.  When the sun is less active, we see more cosmic rays.  This is fairly well understood.  But if Svensmark was correct, it would mean that periods of high solar output should coincide with reduced cloud formation (due to reduced cosmic race incidence), which in turn would have a warming effect on the Earth, since less sunlight would be reflected back into space before hitting the Earth.

Here was a theory, then, that would increase the theoretical impact on climate of an active sun, and better explain why solar irradiance changes might be underestimating the effect of solar output changes on climate and temperatures.

I go on to discuss the recent CERN CLOUD study and what it has apparently found.

I have written before that peer review is not a guarantee of correctness.  Most academics would laugh at that portrayal, yet that is exactly how climate peer review is treated in the media.

A number of years ago, Charles Monnett, flying over the Arctic to do some sort of whale study, saw 3-4 polar bears floating dead in the water.  Without either a) retrieving the bear carcasses or b) even getting a picture of them, he wrote up a paper that discussed the siting and hypothesized the bears drowned in a storm and further that more bears would likely drown in the future if global warming melts more Arctic ice in the summer.  The findings were the basis for a lot of worry about polar bears, and played a key role in Al Gore's movie.   Panic over the dead bears and Monnett's wild hypotheses about them helped fuel calls for declaring the bears endangered, despite all evidence that their populations have actually been increasing over the last few years.  Monnett did quite well from the work, parlaying his fame into management of a $50 million study budget, the dream of all academics.

Monnett's study has come back into the news because there has been some kind of investigation of him and his work by the Feds.  There has been a lot of speculation among skeptics that the investigation focuses on academic fraud, but I thought that a stretch.  As I wrote here

1. If you read between the lines in the news articles, we really have no idea what is going on.  The guy could have falsified his travel expense reports
2. The likelihood that an Obama Administration agency would be trying to root out academic fraud at all, or that if they did so they would start here, seems absurd to me.
3. There is no room for fraud because the study was, on its face, facile and useless.  The authors basically extrapolated from a single data point.  As I tell folks all the time, if you have only one data point, you can draw virtually any trend line you want through it.  They had no evidence of what caused the bear deaths or if they were in any way typical or part of a trend — it was all pure speculation and crazy extrapolation.  How could there be fraud when there was not any data here in the first place?  The fraud was in the media, Al Gore, and ultimately the EPA treating this with any sort of gravitas.

Seriously, you see four floating bear bodies from 1500 feet, once.  You don't have any facts about how they died.  You only have one data point in time.  Where is there room for fraud?  It's one freaking useless data point.    Here is just a taste of what a joke this study was:

The actual survey Monnett was conducting when he observed the dead bears in 2004 was the migration of bowhead whales.  Investigators questioned how he later obtained data for a table listing live and dead polar bear sightings from 1987 to 2004.

“So how could you make the statement that no dead polar bears were observed” during that time period? May asked.

“Because we talked to the people that had flown the flights, and they would remember whether they had seen any dead polar bears,” Monnett said.

They only mystery is how this unbelievably trivial piece of work was published.

Well, now we have a better idea.  The reviewers for the article were Lisa Rotterman and Andrew Derocher.   Incredibly, it turns out Ms. Rotterman is his wife - yes, some people are more peers than others - and Derocher was awarded a large research contract by Monnett just before he reviewed the article.  Wow.

By the way, I think I will be both right and wrong.  I was pretty sure any government investigation would be about misuse of funds, and that does seem to be the main thrust here, though I was wrong in that it does seem to touch on academic fraud as well, in particular the idea of giving out grant money as a quid pro quo for a positive review  (a practice that skeptics have long sustpected in the climate community).

By the way, both Monnett and his partner Gleason now are claiming that everyone blew their study out of proportion and it wasn't really about global warming.  If this is true, they were sure silent about this when they were basking in all kinds of attention and press and grant money.  Either of them could have stepped forward and stopped the momentum that built from this article and they did not.

By the way, for those who still want to believe that the EPA is drive by science,

Gleason concedes that the study had a major impact on the controversial listing of the bear as an endangered species because of global warming.

“As a side note, talking about my former supervisor, he actually sent me an e-mail at one point saying, ‘You’re the reason polar bears got listed,’” Gleason said.

One sighting in history of four floating dead polar bears and suddenly our whole fossil fuel economy has to be shut down.

There may be something interesting coming out in the climate front over the next few weeks from CERN.

Years ago, a researcher named Henrik Svensmark developed a hypothesis that cosmic rays can seed cloud formation, and thus when there are more cosmic rays, there may be more clouds.  This is interesting because it may act as a sort of solar amplification.

Changes in the sun's output through varying solar cycles are measurable, but seem to some scientists to be too small to drive substantial temperature changes on Earth.  But a more active sun tends to blow cosmic rays away from the Earth, thus reducing their incidence.  Therefore, if a more active sun reduced cooling clouds, and a less active sun increased cooling clouds, this might explain a larger effect for the sun.

I have avoided discussing Svensmark much, since the evidence seemed thin, though several labs recently have confirmed his hypothesis, at least in the laboratory.  But Svensmark is definitely a topic among some climate skeptics.  The reason is that higher solar activity levels  in the second half of the twentieth century coincided with much of the 20th century warming that is blamed on manmade CO2.  Svensmark's theory, if true, might force scientists to apportion more of the historic warming to natural causes, thus reducing the estimated sensitivity of the climate to man-made CO2.

But apparently the CERN lab has been undertaking a substantial study to confirm or deny Svensmark's hypothesis.  The results have not been released, but skeptics are beginning to anticipate that CERN's work has confirmed the hypothesis of cosmic ray cloud seeding.  Why?  Because of the dog that did not bark, or rather was told not to bark.

Via Watts Up With That:

CERN Director General Rolf-Dieter Heuer told Welt Online that the scientists should refrain from drawing conclusions from the latest experiment.

“I have asked the colleagues to present the results clearly, but not to interpret them,” reports veteran science editor Nigel Calder on his blog. Why?

Because, Heuer says, “That would go immediately into the highly political arena of the climate change debate. One has to make clear that cosmic radiation is only one of many parameters.”

Skeptics are suggesting that had CERN disproved Svensmark, and thus protected the hypothesis that CO2 is driving most current warming, they would not have hesitated to draw exactly this conclusion in public.  Only a finding considered more consistent with the skeptical position would cause them to go silent, trying to avoid the taint from the politically correct intelligentsia that would come from even partially confirming a skeptic talking point.

I have to agree that Heuer's comments seem to telegraph the result.  I have read a ton of global warming related studies.  And every single one I have read that has ever published negative results vis a vis the hypothesis of catastrophic manmade global warming has felt obligated to put in a sentence at the end that says something like "but of course this does not in any way disprove the hypothesis of anthropogenic global warming and we fully support that hypothesis despite these results."  The absolute fear of becoming an outcast for coming up with the "wrong" result is palpable in reading these papers, sort of like the very careful language a report in Soviet Russia might have used to even mildly criticize some aspect of the state.  Of course, no such disclaimer can be found with narrow positive results - these are always immediately extrapolated  (in fact over-extrapolated in press releases) to be the final nail in the coffin proving once and for all that man is changing the climate in dire ways.

Here is the current global warming hype process as it exists today:

1. Identify a 2 or 3 sigma weather event.  Since there are 365 days in the year and hundreds of different regions in the world, the laws of probability say that some event in the tail of the normal distribution (local high, local low, local flood, local drought, local snow, local tornado, local hurricane, etc) should be regularly occurring somewhere.
2. Play weather event all over press, closely linked as often as possible with supposition that this is due to manmade CO2.  If the connection to global warming is too outlandish to make with a straight face (e.g. cold weather) use term "climate change" or "climate disruption" instead of global warming.
3. Skeptics will point to actual data that this event is not part of a long term trend, e.g. there is no rise in tornado activity correlated with 20th century rise in temperatures so blaming one year of high tornadoes on global warming makes no sense.    Ignore this.
4. Peer reviewed literature will emerge 6-12 months later demonstrating that the event was not likely due to man-made global warming.  Ignore this as well.  Never, ever go back and revisit failed catastrophic predictions.
5. Repeat

Last year's Russian heat wave is a classic example.  Here is an example of the hype and the tie to man-made global warming in Time.  And here, 12 months later, is the study saying that weather was just weather:

Reference
Dole, R., Hoerling, M., Perlwitz, J., Eischeid, J., Pegion, P., Zhang, T., Quan, X.-W., Xu, T. and Murray, D. 2011. Was there a basis for anticipating the 2010 Russian heat wave? Geophysical Research Letters38: 10.1029/2010GL046582.

Background
The authors write that "the 2010 summer heat wave in western Russia was extraordinary, with the region experiencing the warmest July since at least 1880 and numerous locations setting all-time maximum temperature records." And as a result, they say that "questions of vital societal interest are whether the 2010 Russian heat wave might have been anticipated, and to what extent human-caused greenhouse gas emissions played a role."

What was learned
The nine U.S. researchers determined that "analysis of forced model simulations indicates that neither human influences nor other slowly evolving ocean boundary conditions contributed substantially to the magnitude of the heat wave." In fact, they say that the model simulations provided "evidence that such an intense event could be produced through natural variability alone." Similarly, on the observation front, they state that "July surface temperatures for the region impacted by the 2010 Russian heat wave show no significant warming trend over the prior 130-year period from 1880-2009," noting, in fact, that "a linear trend calculation yields a total temperature change over the 130 years of -0.1°C." In addition, they indicate that "no significant difference exists between July temperatures over western Russia averaged for the last 65 years (1945-2009) versus the prior 65 years (1880-1944)," and they state that "there is also no clear indication of a trend toward increasing warm extremes." Last of all, they say that although there was a slightly higher variability in temperature in the latter period, the increase was "not statistically significant."

Not sure I find the computer model work comforting one way or the other but the complete lack of any observational trend seems compelling.

This is pretty hilarious. Environmentalist and global warming advocate Chris Mooney writes

My latest DeSmogBlog post is about how climate skeptics basically seem to believe that their opponents are driven by socialism and communism. We aren’t, of course–duh–but it is fascinating to listen to how they explain this, in their own words.

After some participation years ago in this kind of finger-pointing over motivations in the climate debate, I have of late found such activity to be worthless at best and have tried to stay away from it.

But this became funny when Mooney's readers started commenting on the post.  In effect, they wrote "we are anti-growth socialists."  Mooney was forced to write, in comment #32:

yes. i guess my side loses this round, thanks to this thread. depressing

Thanks to Climate Depot for the tip.

Scene 1, History AP:  My son asked me how WWII ended the Depression.  I said that the draft soaked up a lot of excess workers, which reduced unemployment, and British buying for the war helped our economy but that the war generally destroyed rather than created wealth.  He said, "Dad, you can't tell it to me that way.  The guy grading the AP is going to be a Keynesian."  So we talked multipliers and aggregate demand.

Scene 2, Spanish AP:  My son hands me a list of Spanish words he is trying to learn.  They are the Spanish words for things like "social justice,"  "poverty", "exploitation", etc.  I told him it was an odd selection of words.  He said that nearly every Spanish essay in every Spanish textbook he had ever had were about revolution and stopping the rich from exploiting the poor and fighting global warming.  So he wanted to be prepared for a similar topic on the AP.    After the test, I remembered this conversation and asked him what the essay was.  He said the topic was "show why the government of poor countries should give free bicycles to the poor to fight global warming."

Well, you now have a simple algorithm for sorting flakes and politicized hacks from honest scientists -- anyone who is going around this week saying that the tornadoes in Alabama this week were due to manmade CO2 sit firmly in the former category.  First up, Dr. Roy Spencer

If there is one weather phenomenon global warming theory does NOT predict more of, it would be severe thunderstorms and tornadoes.

Tornadic thunderstorms do not require tropical-type warmth. In fact, tornadoes are almost unheard of in the tropics, despite frequent thunderstorm activity.

Instead, tornadoes require strong wind shear (wind speed and direction changing rapidly with height in the lower atmosphere), the kind which develops when cold and warm air masses “collide”. Of course, other elements must be present, such as an unstable airmass and sufficient low-level humidity, but wind shear is the key. Strong warm advection (warm air riding up and over the cooler air mass, which is also what causes the strong wind shear) in advance of a low pressure area riding along the boundary between the two air masses is where these storms form.

But contrasting air mass temperatures is the key. Active tornado seasons in the U.S. are almost always due to unusually COOL air persisting over the Midwest and Ohio Valley longer than it normally does as we transition into spring.

For example, the poster child for active tornado seasons was the Superoutbreak of 1974, which was during globally cool conditions. This year, we are seeing much cooler than normal conditions through the corn belt, even delaying the planting schedule. Cool La Nina years seem to favor more tornadoes, and we are now coming out of a persistent La Nina. The global-average temperature has plummeted by about 1 deg. F in just one year.

An unusually warm Gulf of Mexico of 1 or 2 degrees right now cannot explain the increase in contrast between warm and cold air masses which is key for tornado formation because that slight warmth cannot compete with the 10 to 20 degree below-normal air in the Midwest and Ohio Valley which has not wanted to give way to spring yet.

The “extra moisture” from the Gulf is not that important, because it’s almost always available this time of year…it’s the wind shear that caused this outbreak.

More tornadoes due to “global warming”, if such a thing happened, would be more tornadoes in Canada, where they don’t usually occur. NOT in Alabama.

Thus we yet again run into the logic of the marketing campaign to change the effect of CO2 from global warming to climate change, as if CO2 could somehow make for random climate changes without the intermediate step of warming.

We all draw upon fallible memories to come to conclusions about whether events are more or less prevalent today, and in many cases our memories fail us (often due to observer bias, in particular the increasing frequency of an event in the media being mistaken for the increasing underlying frequency of the event).  I will say that my memory is that the seventies were the time in my life with the most severe weather (including horrible regional famines) and the seventies were the coldest decade of my life so far.

Anyway, tornadoes are something we can measure, rather than just remember, so let's go to the data:

In An Inconvenient Truth, Al Gore and company said that global warming was increasing the number of tornadoes in the US.  He claimed 2004 was the highest year ever for tornadoes in the US.  In his PowerPoint slide deck (on which the movie was based) he sometimes uses this chart (form the NOAA):

Whoa, that’s scary.  Any moron can see there is a trend there.  Its like a silver bullet against skeptics or something.  But wait.  Hasn’t tornado detection technology changed over the last 50 years?  Today, we have doppler radar, so we can detect even smaller size 1 tornadoes, even if no one on the ground actually spots them (which happens fairly often).  But how did they measure smaller tornadoes in 1955 if no one spotted them?  Answer:  They didn’t.  In effect, this graph is measuring apples and oranges.  It is measuring all the tornadoes we spotted by human eye in 1955 with all the tornadoes we spotted with doppler radar in 2000.   The NOAA tries to make this problem clear on their web site.

With increased national doppler radar coverage, increasing population, and greater attention to tornado reporting, there has been an increase in the number of tornado reports over the past several decades. This can create a misleading appearance of an increasing trend in tornado frequency. To better understand the true variability and trend in tornado frequency in the US, the total number of strong to violent tornadoes (F3 to F5 category on the Fujita scale) can be analyzed. These are the tornadoes that would have likely been reported even during the decades before Dopplar radar use became widespread and practices resulted in increasingtornado reports. The bar chart below indicates there has been little trend in the strongest tornadoes over the past 55 years.

So itt turns out there is a decent way to correct for this.  We don’t think that folks in 1955 were missing many of the larger class 3-5 tornadoes, so comparing 1955 and 2000 data for these larger tornadoes should be more apples to apples (via NOAA).

Well, that certainly is different (note 2004 in particular, given the movie claim).  No upward trend at all when you get the data right.  I wonder if Al Gore knows this?  I am sure he is anxious to set the record straight.

The last chart is dated - am I hiding something?  Nope, here is the update (from here)

By the way, note the 2nd to last bar, which I believe it the 2008 bar (this chart is really hard to read, but it is the only way I have found the data from the NOAA).  In spring of 2008, the media went nuts with a spring spate of tornadoes, saying that the apocalypse was here and this was the ultimate proof of global warming.  In particular, ABC ran a story about how the frequency was twice the previous year.  Beyond the insanity of drawing long term trends in a noisy system from 2 data points, notice that the previous year was virtually the lowest number in half a century, and despite being twice as high, 2008 turned out to be an average to lower-than-average tornado year.  This is what the media does with the climate issue, and why you can trust almost none of it.

Update: By the way, 10 of the top 10 deadliest tornadoes occurred before 1955?  An artifact of increasing wealth, better construction, and in particular better warning and communication systems?  Likely -- it is no accident, I think, these all occurred before the popularization of TV.  However, remember this argument when you see charts of increasing property damage from hurricanes.  These are also an artifact of increasing wealth, but the other way around -- more rich people build expensive houses on the beech, the more property damage from hurricanes irregardless of hurricane strength or frequency.

Update#2:  The entire outbreak may be the third deadliest in the century.

I often find that my worst enemy in an argument is actually someone trying to agree with me but for completely crazed and illogical reasons.  I call it "getting endorsed by Nazis," after the problem politicians face when they get endorsed by some really wacky fringe group.

I have to almost feel some sympathy today for global warming alarmists who have gotten a prominent new climate change spokesman:

Crazed cult leader Charles Manson has broken a 20-year silence in a prison interview coinciding with the 40th anniversary of his conviction for the gruesome Sharon Tate murders - to speak out about global warming.

The infamous killer, who started championing environmental causes from behind bars, bemoaned the 'bad things' being done to environment in a rambling phone interview from his Californian jail cell.

'Everyone’s God and if we don’t wake up to that there’s going to be no weather because our polar caps are melting because we’re doing bad things to the atmosphere.

If I had even the smallest desire to play such games, I might suggest that this would be a really fun article to Google bomb with some frequently-searched global warming phrase.

Several years ago, I offered the following hypothesis to a reporter:

I would argue that the current obsession with small changes to trace levels of CO2 in the atmosphere has in fact gutted the environmental movement.  Nothing else is getting done. ... My prediction– 10-20 years from now, environmentalists are going to look back on the current global warming hysteria as the worst thing ever to happened to the environmental movement.

Here is an example of that effect.  A study comes out that says the following about the health of the Great Lakes:

The Commission is troubled by nearshore eutrophication, aquatic plant growth caused by excessive nutrients, which causes adverse effects on ecosystems, the economy, recreation, and human health.  The reemergence of algal blooms is likely due to multiple factors, including inadequate municipal wastewater and residential septic systems; runoff from increased impervious surface areas and agricultural row-crop areas; discharges from tile drainage which result in more dissolved reactive phosphorus loading; industrial livestock operations; ecosystem changes from invasive mussel species; and impacts from climate change which include warmer water and more frequent and intense precipitation and stormwater events.

Of these listed potential causes, only the last, climate change, is not addressed at all in the main study document, nor is addressing climate change on their list of recommendations, which in fact emphasize that solutions tend to be local.   In fact the tone of the study is that the causes are complex and poorly understood, but never again beyond this sentence is climate change mentioned or any evidence of increased precipitation or runoff presented.

One is left with the impression it was a toss-in on the list, included because climate change is "hot" and sexy and a magnet for funding and attention.  Certainly the report provides no other evidence or detail as to why it is included in the list.  Certainly any intelligent reader would understand that the climate change item was, at best, included to round out the possibilities of a complex and poorly understood problem, but that the study points to many of the other items on the list as more productive places to seek solutions.

So, given this, what do environmental reporters pick up?  Here is the headline environmental reporter Cameron Scott uses on his SFGate blog "the Thin Green Line":

Climate change threatens Great Lakes

Yep, he latched on to the last, least important item that is completely un-adressed by the main report.  By doing so, he is in effect helping to distract attention from the real causes that can be addressed and diverting attention to issues that are tangential at best.  The solution will likely involve better managing agricultural runoffs and dealing with municipal wastewater plants which are under-treating discharges.

This is why I say that the global warming hysteria will be looked back on as a dead time for the environmental movement, when obsession with trace amounts of CO2 either caused folks to lose attention on important issues, or even caused environmentalists to advocate for ecologically detrimental programs (e.g. biofuels).

None of the government's 214 biomass promotion projects — with public funding coming to ¥6.55 trillion — over the past six years has produced effective results in the struggle against global warming, according to an official report released Tuesday.

The Internal Affairs and Communications Ministry, which evaluates public works projects, urged the agriculture and five other ministries conducting biomass projects using sewage sludge, garbage and wood, to take corrective action.

Bryan Caplan links a 2007 study that looks at voter turnout and weather, and specifically tests the conventional wisdom that rain helps Republicans (by disproportionately surpressing the Democratic vote).

The findings appear to be that bad weather does help Republicans and does supress turnout.  However, in studying presidential elections, he finds few that would have had their outcome changed.  Here, however, was one exception:

The results of the zero precipitation scenarios reveal only two instances in which a perfectly dry election day would have changed an Electoral College outcome. Dry elections would have led Bill Clinton to win North Carolina in 1992 and Al Gore to win Florida in 2000. This latter change in the allocation of Florida's electors would have swung the incredibly close 2000 election in Gore's favor.

Since we know from Gore that heavy snow, no snow, heavy rain, and no rain are all caused by global warming, his 2000 electoral defeat was obviously caused by manmade CO2.

(via Popehat) one of the writers at Balloon Juice offers this test of a "reasonable" Conservative blog

1) Do you believe in evolution?

2) Do you believe that the average temperature on earth has increased over the past 30 years?

A few semi-random thoughts:

• Count me as a yes for both
• Is the best test of the likely reasonableness of a political blog really to ask two questions about science that such a blog might never even touch?  This is not an entirely rhetorical question -- just the other day I linked the data that suggested that asking your date about beer might be the best way to test their views on sex.  Sometimes odd cross-correlations exist, but I don't think these would be my first test
• I find the Left's obsession with evolution as a litmus test for political thought to be funny, as the theory of evolution is largely irrelevant to any political questions except fairly narrowly the question of teaching evolution in schools.   I find it funny as much of the Left does not believe in a science - micro economics (very specifically differentiated from macro) - that is also fairly old and well understood and is much more relevant to typical political blog discourse.  I had a debate on national TV a few weeks ago with a man who claimed, as many on the Left will, that raising the minimum wage will increase employment.   If we want to test blogs based on scientific questions, why wouldn't a far more relevant question in public discourse be "do you believe demand curves slope down" or perhaps something like "do you believe breaking windows stimulates the economy?"
• The second test is not a bad test of any site writing about global warming and climate change.  I don't know many science-based skeptics who would deny that global temperatures have likely increased over the last 30 years  (from a data base without UHI or alarmist manual adjustments or large data holes, the trend is something like 0.1C per decade).   I say "likely" because it could be argued that 0.1C is within the error bar of the measurement. Even so, this wouldn't be my first test, even for climate sites
• I would tend to have four tests of the liberal and conservative sites I read
  • Is it interesting to read (after all, this is a freaking unpaid hobby)
  • Is the data-analysis-to-name-calling ratio fairly high
  • Are they willing to step out of team politics and question their own team from time to time
  • Do they have interesting perspectives on individual liberty.  I can plow through Marxist economic posts on progressive sites if from time to time they have a useful perspective on, say, indefinite detentions or gay marriage.  I can plow through some social Conservatism if they have useful posts on economics and fiscal policy.

This post from Nick Gillespie is sort of relevent, in which he talks about CPAC and social conservatives.  One line that struck me

A person's choice of sexual partner in no way means he or she can't be in favor of less spending on farm subsidies.

If I weeded out every blog that held some sort of view with which I disagree (or might even call "unreasonable") I would be down to about 3 blogs in my reader.

California Cap-and-trade plan may be put on hold because they failed to do an Environmental impact study.  LOLOLOL

The California Air Resources Board violated state environmental law in 2008 when it adopted a comprehensive plan to reduce greenhouse gases and again last year when it passed cap-and-trade regulations, a San Francisco Superior Court judge has ruled in a tentative decision.

If the decision is made final, California would be barred from implementing its ambitious plan to combat global warming until it complies with portions of the California Environmental Quality Act, though it is not yet clear what the air board would have to do to be in compliance. The state’s plan, which implements AB32, the Global Warming Solutions Act of 2006, would reduce carbon emissions to 1990 levels by 2020.

Take all the psuedo-quasi-scientific stuff you read in the media about global warming.  Of all that mess, it turns out there is really only one scientific question that really matters on the topic of man-made global warming: Feedback.

While the climate models are complex, and the actual climate even, err, complexer, we can shortcut the reaction of global temperatures to CO2 to a single figure called climate sensitivity.  How many degrees of warming should the world expect for each doubling of CO2 concentrations  (the relationship is logarithmic, so that is why sensitivity is based on doublings, rather than absolute increases -- an increase of CO2 from 280 to 290 ppm should have a higher impact on temperatures than the increase from, say, 380 to 390 ppm).

The IPCC reached a climate sensitivity to CO2 of about 3C per doubling.  More popular (at least in the media) catastrophic forecasts range from 5C on up to about any number you can imagine, way past any range one might consider reasonable.

But here is the key fact -- Most folks, including the IPCC, believe the warming sensitivity from CO2 alone (before feedbacks) is around 1C or a bit higher (arch-alarmist Michael Mann did the research the IPCC relied on for this figure).  All the rest of the sensitivity between this 1C and 3C or 5C or whatever the forecast is comes from feedbacks (e.g. hotter weather melts ice, which causes less sunlight to be reflected, which warms the world more).  Feedbacks, by the way can be negative as well, acting to reduce the warming effect.  In fact, most feedbacks in our physical world are negative, but alarmist climate scientists tend to assume very high positive feedbacks.

What this means is that 70-80% or more of the warming in catastrophic warming forecasts comes from feedback, not CO2 acting alone.   If it turns out that feedbacks are not wildly positive, or even are negative, then the climate sensitivity is 1C or less, and we likely will see little warming over the next century due to man.

This means that the only really important question in the manmade global warming debate is the sign and magnitude of feedbacks.  And how much of this have you seen in the media?  About zero?  Nearly 100% of what you see in the media is not only so much bullshit (like whether global warming is causing the cold weather this year) but it is also irrelevant.  Entirely tangential to the core question.  Its all so much magician handwaving trying to hide what is going on, or in this case not going on, with the other hand.

To this end, Dr. Roy Spencer has a nice update.  Parts are a bit dense, but the first half explains this feedback question in layman's terms.  The second half shows some attempts to quantify feedback.  His message is basically that no one knows even the sign and much less the magnitude of feedback, but the empirical data we are starting to see (which has admitted flaws) points to negative rather than positive feedback, at least in the short term.  His analysis looks at the change in radiative heat transfer in and out of the earth as measured by satellites around transient peaks in ocean temperatures (oceans are the world's temperature flywheel -- most of the Earth's surface heat content is in the oceans).

Read it all, but this is an interesting note:

In fact, NO ONE HAS YET FOUND A WAY WITH OBSERVATIONAL DATA TO TEST CLIMATE MODEL SENSITIVITY. This means we have no idea which of the climate models projections are more likely to come true.

This dirty little secret of the climate modeling community is seldom mentioned outside the community. Don’t tell anyone I told you.

This is why climate researchers talk about probable ranges of climate sensitivity. Whatever that means!…there is no statistical probability involved with one-of-a-kind events like global warming!

There is HUGE uncertainty on this issue. And I will continue to contend that this uncertainty is a DIRECT RESULT of researchers not distinguishing between cause and effect when analyzing data.

If you find this topic interesting, I recommend my video and/or powerpoint presentation to you.

For those of you worried, the coyote that was shot by the Boston environmental police (!) was no relation.  Though I would not be surprised if RFK Jr. had them ordered after me, given his statements about global warming skeptics.  HT TJIC

I am really just amazed by these remarks by NCAR's Dr. Ken Trenberth to be given, apparently planned for the American Meteorological Society gathering this month.   The and Anthony Watt has reprinted it on his blog.

It is hard to know where to start, but the following excerpt is an outstanding example of climate science process where 1.  Conclusions are assumed; 2.  Conclusions are deemed unequivocal by reference to authority; 3. Debate rules are proposed wherin it is impossible to refute the conclusion; 4.  All weather events that make the news are assumed to be caused or made worse by man-made warming, and thereby, in circular fashion, further prove the theory.

Now he has gone totally off the scientific reservation into astrology or the occult or something.   He is saying that there is a high probability that if CO2 levels were 120ppm lower that, for example, the floods in Pakistan would not have occurred.  This is pure conjecture, absolutely without facts, and probably bad conjecture at that.  After all, similar events of similar magnitude have occurred through all of recorded history in exactly these locations.

Some Notes

1.  For those unfamiliar with the issues, few skeptics deny that man's CO2 has no effect on warming, but believe the effect is being enormously exaggerated.  There is a bait and switch here, where the alarmist claims that "man is causing some warming" is the key conclusion, and once accepted, they can head off and start controlling the world's economy (and population, as seems to be desired by Trenberth).   But the fact that CO2 causes some greenhouse warming is a trivial conclusion.  The hard part is, in the complex climate system, how much does it cause.  There is a an argument to be made, as I have, that this warming is less than 1C over the next century.  This number actually has observational data on its side, as actual warming over the last century, given past CO2 increases, is much more consistent with my lower number than various alarmist forecasts of doom.  Again, this is discussed in much more depth here.

2.  One interesting fact is that alarmists have to deal with the lack of warming or increase in ocean heat content over the last 12 years or so.  They will argue that this is just a temporary aberration, and a much shorter time frame than they are working on.  But in effect, the core IPCC conclusions were really based on the warming over the 20 years from 1978-1998.  So while 12 years is admittedly short compared to many natural cycles in climate, and might be considered a dangerously short period to draw conclusions from, it is fairly large compared to the 20 year period that drove the IPCC conclusions.

Update: More thoughts from the Reference Frame.

The other day, environmental blog the Thin Green Line wrote:

At the American Geophysical Union meeting late last month, University of Miami geologist Shimon Wdowinski argued that the devastating earthquake a year ago may have been caused by a combination of deforestation and hurricanes (H/T Treehugger). Climate change is spurring more, stronger hurricanes, which are fueled by warm ocean waters....

The 2010 disaster stemmed from a vertical slippage, not the horizontal movements that most of the region's quakes entail, supporting the hypothesis that the movement was triggered by an imbalance created when eroded land mass was moved from the mountainous epicenter to the Leogane Delta.

I have heard this theory before, that landslides and other surface changes can trigger earthquakes.  Now, I am not expert on geology -- it is one of those subjects that always seems like it would be interesting to me but puts me in a coma as soon as I dive into it.   I almost failed a pass-fail geology course in college because in the mineral identification section, all I could think to say was "that's a rock."

However, I do know enough to say with some confidence that surface land changes may have triggered but did not cause the earthquake.  Earthquakes come from large releases of stored energy, often between plates and faults.  It's remotely possible land surface changes trigger some of these releases, but in general I would presume the releases would happen at some point anyway.  (Steven Goddard points out the quake was 13km below the surface, and says "It is amazing that anyone with a scientific background could attempt to blame it on surface conditions.")

The bit I wanted to tackle was the Thin Green Line's statement that "Climate change is spurring more, stronger hurricanes."   This is a fascinating statement I want to attack from several angles.

First, at one level it is a mere tautology.  If we are getting more hurricanes, then by definition the climate has changed.   This is exactly why "global warming" was rebranded into "climate change," because at some level, the climate is always changing.

Second, the statement is part of a fairly interesting debate on whether global warming in general will cause more hurricanes.  Certainly hurricanes get their power from warm water in the oceans, so it is not unreasonable to hypothesize that warmer water would lead to more, stronger hurricanes.  It turns out the question, as are most all questions in the complex climate, is more complicated than that.  It may be hurricanes are driven more by temperature gradients, rather than absolute temperatures, such that a general warming may or may not have an effect on their frequency.

Third, the statement in question, as worded, is demonstrably wrong.  If he had said "may someday spur more hurricanes," he might have been OK, but he said that climate change, and by that he means global warming, is spurring more hurricanes right now.

Here is what is actually happening (paragraph breaks added)

2010 is in the books: Global Tropical Cyclone Accumulated Cyclone Energy [ACE] remains lowest in at least three decades, and expected to decrease even further... For the calendar year 2010, a total of 46 tropical cyclones of tropical storm force developed in the Northern Hemisphere, the fewest since 1977. Of those 46, 26 attained hurricane strength (> 64 knots) and 13 became major hurricanes (> 96 knots).

Even with the expected active 2010 North Atlantic hurricane season, which accounts on average for about 1/5 of global annual hurricane output, the rest of the global tropics has been historically quiet. For the calendar-year 2010, there were 66-tropical cyclones globally, the fewest in the reliable record (since at least 1970) The Western North Pacific in 2010 had 8-Typhoons, the fewest in at least 65-years of records. Closer to the US mainland, the Eastern North Pacific off the coast of Mexico out to Hawaii uncorked a grand total of 8 tropical storms of which 3 became hurricanes, the fewest number of hurricanes since at least 1970.

Global, Northern Hemisphere, and Southern Hemisphere Tropical Cyclone Accumulated Energy (ACE) remain at decades-low levels.

The source link has more, and graphs of ACE over the last several decades (ACE is a sort of integral, combining the time-average-strength of all hurricanes during the year.  This is a better metric than mere counts and certainly better than landfall or property damage metrics).

So, normally I would argue with alarmists that correlation is not causation.   There is no point in arguing about causation, though, because the event he claims to have happened (more and stronger hurricanes) did not even happen.  The only way he could possibly argue it (though I am pretty sure he has never actually looked at the hurricane data and simply works from conventional wisdom in the global warming echo chamber) is to say that yes, 2010 was 40-year low in hurricanes, but it would have been even lower had it not been for global warming.  This is the Obama stimulus logic, and is just as unsupportable here as it was in that context.

Postscript: By the way, 2010 was probably the second warmest year in the last 30-40 years and likely one of the 5-10 warmest in the last century, so if warming was going to be a direct cause of hurricanes, it would have been in 2010.    And yes, El Ninos and La Ninas and such make it all more complicated.  Exactly.  See this post.

From New York City Councilman James Genarro's web site:

Gennaro has received numerous accolades for his work as Chairman of the Council's Committee on Environmental Protection, and has authored many of the Council's most progressive environmental bills. Gennaro has spearheaded efforts to cut the city's global warming pollution emissions,... put more "clean air" vehicles on city streets, ...make the city's electricity more reliable, clean, and affordable,... and promote "green buildings".

Thinking about the public and private resources invested in these efforts, I wonder how many snow plows they would have paid for.

Paul Krugman has become pretty famous for being able to peer into the complex economy and find something to justify whatever he is promoting.  Higher interest rates, lower interest rates, more growth, less growth, unemployment, or boom times all simultaneously are proof of whatever theory he currently holds (which, in turn, is generally exactly the theory required to support actions by the Democratic leadership).

In the same way -- hot weather, cold weather, drought, wet weather, mild weather, lost of hurricanes, a lack of hurricanes -- are all simultaneously the proof for man-made global warming.  Whatever the weather currently is, someone can use a government grant to build a model to prove that it is due to anthropogenic global warming.  Thus this story -- Global warming causing freezing.

From the WaPo

With United Nations climate negotiators facing an uphill battle to advance their goal of reducing emissions linked to global warming, it's no surprise that the woman steering the talks appealed to a Mayan goddess Monday.

Christiana Figueres, executive secretary of the U.N. Framework Convention on Climate Change, invoked the ancient jaguar goddess Ixchel in her opening statement to delegates gathered in Cancun, Mexico, noting that Ixchel was not only goddess of the moon, but also "the goddess of reason, creativity and weaving.

The Mayans used to also cut the hearts out of living human beings as sacrifices to their gods, an apt metaphor for what the assembled UN delegates want to do to development and the world economy.

Regular readers will have no doubts about my skepticism of the theory of catastrophic man-made global warming.  In particular, in these pages and at Climate Skeptic, I have repeatedly criticized the details of Michael Mann's work on the hockey stick.  I won't repeat those issues today, though some of the past articles are indexed here.

That being said, efforts by Republicans in Virginia to bring legislative or even criminal action against Mann for his work when he was at the University of Virginia is about the worst idea I have heard in quite some time.  Though nominally about forcing public disclosure (something I am always in favor of from state entities) the ultimate goal is to drag Mann into court

Cuccinelli has said he wants to see whether a fraud investigation would be warranted into Mann's work, which showed that the earth has experienced a rapid, recent warming

[As an aside, this is actually NOT what Mann's hockey stick work purports to show.  The point of the hockey stick is to make the case that historic temperatures before 1850 were incredibly stable and flat, and thus recent increases of 0.6-0.8C over the last 150 years are unprecedented in comparison.   His research added nothing to our knowledge about recent warming, it was on focused on pre-industrial warming.   The same folks that say with confidence the science is settled don't even understand it].

For those frustrated with just how bad Mann's work is and upset at the incredible effort to protect this work from criticism or scrutiny by hiding key data (as documented in the East Anglia climategate emails), I know it must feel good to get some sort of public retribution.  But the potential precedent here of bringing up scientists on charges essentially for sloppy or incorrect work is awful.

Bad science happens all the time, completely absent any evil conspiracies.  Human nature is to see only the data that confirms ones hypotheses and, if possible, to resists scrutiny and criticism.  This happens all the time in science and if we started hauling everyone into court or into a Senate committee, we have half of academia there  (and then likely the other half when the party in power changed).  Team politics are a terrible disease and the last thing we need is to drag them any further into science and academia.

Science will eventually right itself, and what is needed is simply the time and openness to allow adversarial scrutiny and replication within academia to run its course.  Seriously, are we next going to drag the cold fusion guys in to court?  How about all the folks in the geology field that resisted plate tectonics for so long.  Will we call to account the losers in the string theory debate?

If legislators want to help, they can

• Make sure there are standards in place for archiving and public availability of any data and code associated with government funded research
• Improve the governments own climate data management
• Ensure that state funding is distributed in a way to support a rich dialog on multiple sides of contested scientific issues.
