I am reposting this from several years ago, but I am doing it on June 7 because last time when I posted it on June 6 people called me disrespectful.  I am not really sure I understand why, but this characterization is so wrong (I already have a trip lined up to be in Normandy next year around the 75th anniversary) that it is easier just to hold off for a day.

Over time, my understanding of the importance of the D-Day invasions has shifted.  Growing up, I considered these events to be the single key event in defeating the Nazis.  Listening to the radio this morning, this still seems to be the common understanding.

Over time, I have had to face the fact that the US (or at least the US Army) was not primarily responsible for defeating Germany -- the Russians defeated Germany, and what's more, would have defeated them whether the Allies had landed in France or not.  Check out the casualties by front, from Wikipedia:

The Russians defeated Germany.  Period.   And I don't think the western allies would ever have had the stomach to inflict the kind of casualties on Germany that were ultimately necessary to defeat her without Russian help.  To me, this is the great irony of WWII, that it was not ultimately a victory for democracy.  Only totalitarian Russia could defeat totalitarian Germany.  This thought often bothers me a lot.  It doesn't fit with how we want to view the war.

However, D-Day did have an important effect -- it kept Western Europe out of Soviet hands.  We did not know it at the time, but I would argue in retrospect that from mid-1944 on we were competing with Russia to see how Europe would get divided up after the war.  D-Day allowed the western allies to overrun most of Western Europe and keep it out of Soviet hands, perhaps an even more important outcome than just speeding the defeat of the Germans.  Sure, FDR gets grief for giving the farm away to Russia at Yalta, but what could he do?  The Soviet occupation of Eastern Europe at that point was a fait accompli.  What would have been FDR & Churchill's negotiation position at Yalta if their armies were not even on the continent (excepting Italy, where we might still be fighting in 2014 and getting nowhere)?

Postscript:  There is no doubt that some German troops were pinned down in the West by the invasion, but many of these troops were already pinned down by the mere threat of invasion.   Only the experienced soldiers and new equipment gathered by Hitler for the Wacht am Rhein, what we now refer to as the Battle of the Bulge, were a major diversion from the East due to the invasion, and even that was a relatively small amount of reserves compared to the immensity of the Eastern Front.  Had we overrun the industrial Ruhr earlier, that would have made a real difference but we only really achieved this a few months before Berlin was taken.

There are a lots of what-ifs about the war in the West and about how the war might have been shortened.  What if Montgomery really could have taken Cannes on D+1?  That if the Allies had taken the larger solution to trap more Germans at Falais?  What if the Allies had given limited supplies to Patton rather than Montgomery and Operation Market-Garden?  What if Eisenhower had been less timid about trapping the Germans in the Bulge?

But I think the most interesting missed opportunity was a small one with huge impact -- what if the Allies had been more aggressive in taking the Scheldt Estuary?  The Allies were desperately short of supplies in Northern France in the Fall of 1944.  They simply could not get enough supplies over the beaches at Normandy and across France to support all the armies they had in play.  They needed a real high-capacity port in the North and they actually captured one in Antwerp almost intact around September 3.  Antwerp, though, is not right on the ocean -- boats had to come down an estuary which the Germans still controlled.  Quick action in early September could have easily cleared the estuary and made the port almost immediately use-able.   The Allies took only half measures and basically dithered for a while, failing to see the opportunity, as the Germans continued to fortify their position.  In the end, it was not until nearly December before Antwerp could act as a port, long after the opportunity for a coup de grace of the Germans in the West had passed.  If you are interested, here is the Wikipedia article on the Battle of the Scheldt.

Update:  by the way, there were lots of good comments on the original post and you can see them here.

Most folks even slightly acquainted with the climate debate have seen Dr. Mann's hockey stick.  It is a historical temperature reconstruction using proxies such as the width of tree rings.

There were a zillion problems with this analysis, which I and many covered years ago and, frankly, I am past my tolerance in reiterating once again.  Just to name three:

• The inflection of the hockey stick occurs right where two completely different data sets - proxies and actual thermometer readings -- have been grafted together, leading one to wonder if the inflection is a real natural phenomenon or instead related to differences in how the data was gathered
• The blue line, of the proxy data, ends in 1950.  The reason for that is that the proxy data actually shows temperatures falling since 1950.  This does not mean that temperatures actually fell - we are sure they have risen -- it means that the proxies are not very good proxies.  If they are not following temperatures well in the last 50 years, why do we think they mirrored temperatures well in the 1000 years before that?
• As Steve McIntyre showed, while Mann used many proxies, his statistical method basically over-weighted a single data set from bristlecone pines in California and used techniques that were shown later to generate hockey sticks even from random noise.

Anyway, you can search Google and spend most of the day reading critiques and defenses of Mann.

But I think a lot of laymen missed the point of the analysis.  Folks want to say that the hockey stick proves we have a big current spike in temperatures -- ie they focus on the blade of the hockey stick.  But we already knew from surface temperature records that world temperatures have risen perhaps 0.8C over the last century.  And besides, as mentioned above, Mann's proxy data does not even confirm or support the current working.

No, the "insight" of the hockey stick analysis was the handle -- the fact that until 1900, Mann was essentially claiming that temperatures had been 1) dead flat with limited variation and 2) consistently well below current temperatures.  Prior to Mann's analysis, most scientists had a picture of past climate that had a warm period from 1000-1300 that was perhaps as warm as it is today followed by a cold period  (called the medieval warm period and the little ice age).  Most of this was based on historical analysis.  Go to your local university and find a medieval historian.  Going forward, universities will probably not teach any European history any more, but you probably can find a few old folks still hanging on via tenure.  I took an audio course from Philip Daileader of William and Mary and he started his course on the high middle ages (1000-1300) by saying the most important fact of that period was the demographic expansion allowed in part by a warm and favorable climate.  The warm climate allowed more food production as new areas, particularly in the north, could be brought into production.  In turn, after 1300, Europe was met with a cooler and wetter climate that created a horrible famine in the 1320's, which in turn likely weakened the population and made the black death a few decades later all the worse.  Later on, we have records of canals and rivers freezing across Europe that almost never freeze today.  This colder period lasted until the early 19th century (I use 1812 as a break as I think of the freezing Russian winter of that year that sent Napoleon home without most of his army).  Temperatures and sea levels began rising after that, long before man was burning fossil fuels in earnest.

This historical picture, shared by pretty much everyone until 20 years ago, was overturned by Mann.  Look at his chart - no warm period in the middle ages, and no substantially colder period just afterwards.  How did he refute the historical evidence, which is robust?  He waved this evidence off as limited to Western Europe.  Which was sort of funny, because most of his proxy data came from an even smaller area, the mountains east of Bishop, CA**.

So all this is a leadup to a new study out of China looking at temperature proxies for China.  And it turns out China, which is on the other side of the world from the west (I know that because when Bugs Bunny digs straight down he always comes out in China), has pretty much the same temperature history everyone before Michael Mann thought we had in Europe.

**postscript:  If you have a sports car, and want to drive a curving mountain road that does not have a lot of big cliffs and has pretty much zero other cars to get in the way, you might try Highway 168 from near Bishop up towards the ancient bristlecone pine forest.

I love these US Army intelligence maps from Western Europe on December 15 and then on December 16, 1944 (before and after the German invasion).  A useful lesson for folks who do not greet all intelligence reports with a lot of skepticism.

The invaluable Carpe Diem blog has a compendium of 18 forecasts of doom that were made on or around the first Earth Day in 1970 -- all of which turned out wrong.   Here is an example:

8. Peter Gunter, a North Texas State University professor, wrote in 1970, “Demographers agree almost unanimously on the following grim timetable: by 1975 widespread famines will begin in India; these will spread by 1990 to include all of India, Pakistan, China and the Near East, Africa. By the year 2000, or conceivably sooner, South and Central America will exist under famine conditions….By the year 2000, thirty years from now, the entire world, with the exception of Western Europe, North America, and Australia, will be in famine.”

9. In January 1970, Life reported, “Scientists have solid experimental and theoretical evidence to support…the following predictions: In a decade, urban dwellers will have to wear gas masks to survive air pollution…by 1985 air pollution will have reduced the amount of sunlight reaching earth by one half….”

Participants in the global warming debate today will surely recognize the formulation of these statements as representing a consensus scientific opinion.

For those of you too young to actively follow the news in the 1970s, Mark Perry is not cherry-picking cranks.  These fearful quotations are representative of what was ubiquitous in the media of that time.

My school (Kinkaid in Houston) took speech and debate very seriously and had a robust debate program even in middle school.  In 1975-1976 the national debate topic was this:

Resolved:  That the development and allocation of scarce world resources should be controlled by an international organization

The short answer to this proposition should realistically have been:  "you have got to be f*cking kidding me."  But such were the times that this was considered a serious proposal worth debating for the entire year.  In fact, in doing research, it was dead-easy to build up suitcases of quotations of doom to support the affirmative;  it was far, far harder finding anyone who would argue that a) the world was not going to run out of everything in a few decades and b) that markets were an appropriate vehicle for managing resources.   I could fill up an hour reading different sources predicting that oil would have run out by 1990 or 2000 at the latest.

Over time, my understanding of the importance of the D-Day invasions has shifted.  Growing up, I considered these events to be the single key event in defeating the Nazis.  Listening to the radio this morning, this still seems to be the common understanding.

Over time, I have had to face the fact that the US (or at least the US Army) was not primarily responsible for defeating Germany -- the Russians defeated Germany, and what's more, would have defeated them whether the Allies had landed in France or not.  Check out the casualties by front, from Wikipedia:

Some professors are arguing about online education.  I will not comment on that particular topic right now, though it sounds a bit like two apatosauruses arguing about whether they should be worried about the comet they just saw.

I did, however, want to comment on this, from an SJSU professor to a Harvard professor, I assume pushing back on online course work designed by Harvard.  Emphasis added.

what kind of message are we sending our students if we tell them that they should best learn what justice is by listening to the reflections of the largely white student population from a privileged institution like Harvard? Our very diverse students gain far more when their own experience is central to the course and when they are learning from our own very diverse faculty, who bring their varied perspectives to the content of courses that bear on social justice…

having our students read a variety of texts, perhaps including your own, is far superior to having them listen to your lectures. This is especially important for a digital generation that reads far too little. If we can do something as educators we would like to increase literacy, not decrease it…the thought of the exact same social justice course being taught in various philosophy departments across the country is downright scary — something out of a dystopian novel…

I would have said that teaching social justice at all and requiring students to take it at many universities was something out of a dystopian novel.  In fact, the whole concept of social justice, wherein it is justified that certain groups can use the coercive force of government to get whatever they may fancy merely by declaring that there is a right to it (e.g. health care), actually underlies a number of dystopian novels.

Postscript #1:  If find it hilarious that the SJSU rejects Harvard-created course materials because they are the product of white privilege.  I cannot speak to Harvard undergrad, but my son is at Amherst which could certainly be lumped into the same category (any college named after an early proponent of biological warfare against Native Americans has to be up there in the white privilege category).  My son actually gave up his earlier plan to study history when he looked at the course catalog.  It was impossible to simply study, say, the political and economic history of Western Europe.  All the courses are such things as "the role of women in the development of Paraguayan aboriginal rights."

Postscript #2:  I don't have the larger context for this letter but it strikes me the professor is stuck in the typical leftist technocratic top-down and centralized single mandated approach to anything.  Why is it that online courses would end up with no viewpoint or content competition?  The Internet has increased the access of most people to a diversity of ideas that go beyond what they got in the morning fish-wrap and from Uncle Walter on TV.  Why would it have the opposite effect in education?  Or perhaps that is what the professor is worried about, a loss of control of the education message by the current academic elite, to be feared in the same way the Left hates Fox News.

Via Cafe Hayek, Paul Krugman says:

And surely the fact that the United States is the only major advanced nation without some form of universal health care is at least part of the reason life expectancy is much lower in America than in Canada or Western Europe.

If I were a cynical person, I might think that the tortured and overly coy syntax of this statement is due to the fact that Krugman knows very well that the causation he is implying here is simply not the case.  Rather than rehash this age-old issue here on Coyote Blog, let's roll tape from a post a few years ago:

Supporters of government medicine often quote a statistic that shows life expectancy in the US lower than most European nations with government-run health systems.  But what they never mention is that this ranking is mainly due to lifestyle and social factors that have nothing to do with health care.  Removing just two factors - death from accidents (mainly car crashes) and murders - vaults the US to the top of the list.  Here, via Carpe Diem, are the raw and corrected numbers:

And so I will fire back and say, "And surely the fact that the United States is the only major advanced nation without some form of universal health care is at least part of the reason life expectancy related to health care outcomes is so much higher in America than in Canada or Western Europe.

And check out the other chart in that post from that study:

US cancer survival rates dwarf, yes dwarf those of other western nations.    Even black males in the US, who one would suppose to be the victims of our rapacious health care system, have higher cancer survival rates than the average in most western nations (black American women seem to have uniquely poor cancer survival rates, I am not sure why.  Early detection issues?)

All this data came originally from a post at Carpe Diem, which I refer you to for source links and methodologies.

I kid you not

So how did Genghis Khan, one of history's cruelest conquerors, earn such a glowing environmental report card? The reality may be a bit difficult for today's environmentalists to stomach, but Khan did it the same way he built his empire — with a high body count.

Over the course of the century and a half run of the Mongol Empire, about 22 percent of the world's total land area had been conquered and an estimated 40 million people were slaughtered by the horse-driven, bow-wielding hordes. Depopulation over such a large swathe of land meant that countless numbers of cultivated fields eventually returned to forests.

In other words, one effect of Genghis Khan's unrelenting invasion was widespread reforestation, and the re-growth of those forests meant that more carbon could be absorbed from the atmosphere.

Weirdly, the author equates cooling the Earth with "a glowing environmental report card?"  How did cold become green?

In fact, the world did substantially cool in the 14th century.  The previous 300 warm years had brought prosperity and growth to Western Europe, in fact the first population growth in Europe since as early as 300AD.  The commercial and intellectual regression that is often called the Dark Ages or the early Middle Ages (say 700-1000AD) is often attributed to a demographic collapse in Western Europe.  There are many who credit, at least in part, this collapse for the fall of the Western Roman Empire.

The years 1000-1300 saw a real recovery, the first population growth for hundreds of years, and a number of important (though to us prosaic) technological, intellectual and societal advances. There are several factors behind this boom, but a large one is the Medieval Warm Period, where we can find records of certain crops (e.g. grapes in England) being grown far north of where they can be even today.

The early 1300's coincided with the return of cold, wet weather to Europe.  Whether this is in part attributable to Genghis Khan's killing rampage, I can't say.  But the effects were clear.  The 1320's and 1330's saw a series of terrible harvests and resulting famines.   By the 1340's, much of Europe was hungry and malnurished, weakening the population for the arrival of some rats carrying Bubonic Plague.  Again, not a few historians have noted that the climate-change-induced famines of the early 1300's likely made the early plagues more virulent.

This world of failed harvests, starving, and plagues -- this is a greener world we should aspire to?

Hillary apparently wants to sue OPEC for not producing enough oil. If this idea had come in via the constituent mail, Hillary's staffers would probably have laughed themselves silly, but it is an election year, and no bottom has been found below which candidates are unable to keep a straight face while uttering what they know to be nonsense.

But should Hillary be suing OPEC, or the US?  Because if you ranked the world's countries on those that are doing the least to develop the most promising potential oil deposits, the US would be right at the top of that list.  By Hillary's logic, Western Europe and Japan should be suing us.
