Last month I heard a conservative radio talk show host proclaim, "Hah! It's snowing in Arizona. Guess this will make John McCain change his mind about global warming."
Idiocy must be contagious, because yesterday I heard something similar (on CNN, I believe). The weather person was saying that it was unusually cold in the central and eastern parts of the United States.
The anchor responded with something like "Well, that's interesting, since the Copenhagen conference on global warming happened not long ago." Before he could expand upon this illogical train of thought, the weather expert interrupted to save him from further embarrassment.
"When it's colder than normal in one area, it's usually warmer than normal somewhere else. Currently the jet stream is sending cold air from the arctic down into the heart of the country. But in Juneau, Alaska, it's warmer than in Chicago right now."
Like this Climate Progress blog post says, Duh! A cold snap doesn't disprove global warming. Obviously.
Problem is, our not-always-so-great United States is filled with people who either (1) don't know much about science, (2) don't care much about science, or (3) pretend to not know or not care much about science in at an attempt to score political points.
Regardless of the reason, it's hard for me to accept that someone could be so dense as to believe that just because it's really cold and snowy some place where it usually isn't, this shows that global warming isn't happening.
In most winters, and certainly those in the last 20 years or so, our winds normally come from the south-west. This means air travels over the relatively warm Atlantic and we get mild conditions in the UK. However, over the past three weeks the Atlantic air has been ‘blocked’ and cold air has been flowing down from the Arctic or the cold winter landmass of Europe.
...The current cold weather in the UK is part of the normal regional variations that take place in the winter season. It doesn’t tell us anything about climate change, which has to be looked at in a global context and over longer periods of time.
Even though during the past few weeks it's been colder than normal in parts of the United States and Europe, it's been warmer than normal in other areas of the world. (Bluish areas are colder, reddish areas are warmer.)
Nonetheless, facts don't stand in the way of anti-scientific global warming deniers. Media Matters addresses this subject in "Are You Smarter Than a Fifth Grader?: Climate Change Edition."
Answer: not if you're on Fox News.
Cold weather has come to almost inevitably yield reflexively mindless right-wing media attacks on the scientific consensus about global climate change. Yes, when it's chilly outside, particularly if it happens to snow, media conservatives go into hysterical fits -- declaring the idea that global climate change actually exists and is at least in part caused by humans a complete farce.
Actually, what's farcical is someone saying Ooh, it's cold! That disproves global warming!
