Air Conditioning Is Causing Global Warming
Yep, I admit it, air conditioning may indeed be causing us to measure higher temperatures. Here is the historic temperature plot of Detroit Lake, MN, one of the thousand or so measurement points in the data base that is used to compute historical warming in the US.
Look at that jump in the last 10 years. It must be global warming! Can't possibly be due to these air conditioning units installed around 2000 and venting hot gas on the temperature instrument (in that round louvered thing on the post).
More from Anthony Watts, who is leading the effort to document all these stations. You too can help. The odds are you live less than an hour from one of these stations -- take your camera and add it to the data base. Its fun!
Incredibly, the global warming community still argues that documenting the quality of the installations used in the official global warming numbers is unnecessary. More air conditioners blowing on official temperature measurements here. Worst temperature installation found to date here, "coincidently" at the site with the highest measured 20th century warming.

I am a regular reader of your blog. And I am very impress with your blog upon Global Warming. Now I am also write a blog upon Global Warming. This blog is collection of news & reviews like the study found that global warming since 1985 has been caused neither by an increase in solar radiation nor by a decrease in the flux of galactic cosmic rays. Some researchers had also suggested that the latter might influence global warming because the rays trigger cloud formation.

The carelessness with which these sites are administered is breathtaking. Really.

I am not sure if it is totally carelessness, or possibly there is some intent involved.
Actually, though I am suspicious, I am of the philosphy that most of the time when something can be explained through either carelessness or evil intent, it is almost always caused by carelessness.

The Air Conditioner danger has been very over-dramatized (and not backed up with HVAC calculations of throw, etc.) by Watts et al. I have even see him worry about window units 15 feet higher and 30 feet away from sensors.

The fumes emitted by air conditioning units are said to be detrimental to the environment and that it causes global warming

With new technology, air conditioning units are becoming more and more environmentally friendly. Older models were not the best because of the pollution they emitted. But not many people are updating their units to better ones which is better for everyone!

I do believe that air conditioning system is a contributing factor to the said global warming. One way to minimize the effect is by choosing environment friendly system. Keep it up!

Can one say that the compressor is a source of global warming? If yes, please elaborate how and why?

Hello, just my honest opinion. It might be caused by the type of refrigerant used in AC. If I'm not mistaken Freon or R-22 contributes to global warming, and in that case a much ozone friendly refrigerant should be used in place of R-22. Anyway, there are already commercially available refrigerant for ACs that have less ozone depletion impact.
