Record Heat a Sign of Global Warming or is it just Record Heat?

Week in Review

It’s hot.  And dry.  The heat this year has been setting records. But is it a portent of things to come?  Is the global warming apocalypse upon us?  Or is it just hot (see What’s Behind The Record Heat? by Douglas Main posted 7/3/2012 on Yahoo! News)?

Heat is beating records around the country: the first five months of 2012 have been the hottest on record in the contiguous United States. And that’s not including June, when 164 all-time high temperature records were tied or broken around the country, according to government records…

The warm summer follows an unusually warm winter, which was the hottest and driest that the western United States has ever seen since records have been kept, said Jeff Weber, a scientist with the University Corporation for Atmospheric Research in Boulder, Colo…

The early heat waves of summer — following higher temperatures in spring and winter — could also be part of a pattern of climate change.

“It’s consistent with what we’d expect in a warming climate, but it’s hard to quantify any effect climate change might have on an individual event like this heat wave,” Crouch said.

While only one heat wave cannot by itself be linked to climate change, a significant increase in these types of events over time could be a hallmark of a warming planet. “An increasing frequency of heat waves —that’s one aspect of climate change you can point to,” Carbin said.

It’s been hot and dry.  We had a warm winter.  And are now suffering through a heat wave.  A lot of people like to say “See?” with all knowing condescension.  That it’s proof positive that the climate is changing.  Because hot dry weather is clearly a sign of global warming.  Even if a scientist from the Atmospheric Research in Boulder, Colorado, is not ready to say “See?” with all knowing condescension. 

So what’s happening in the rest of the world?  Is the rest of the world suffering from these unseasonably high temperatures and lack of precipitation?  Is there a pattern here?  Let’s see what’s happening in Britain (see IT WILL RAIN ‘TIL SEPTEMBER by Sarah Westcott posted 7/7/2012 on Express).

BRITAIN is facing its “worst ever” summer with cold wet weather ruining family holidays and blighting the Olympics, forecasters warned last night.

August is set to be a washout following a miserable July and the wettest June since records began – meaning summer is effectively over.

Well, cold wet weather is clearly not a hot, dry heat wave.  So, no, there is no pattern.  While the US broils in a heat wave the UK is cold and wet.  So global warming is not to blame for the current hot spell in the US.  Because, globally, it’s not warm.  It’s cold and wet in parts.  Unless warming both warms and cools.  Which is about as likely as finding a square circle.  (Which doesn’t exist, of course).
