Changes in local temperature are not indications of change in global climate, and if somebody is arguing they are from the anti-AGW side - shame on
you.
For God sakes man, don't you remember? Back when global temperatures were rising, and even after they started to flat line that "just look out your
backdoor argument", was the one that used to drive us crazy. How do you get through that kind of mistaken reasoning, we used to ask.
Things like snow in Saudi Arabia, or the livestock freezing to death in China in the winter of 2007, are only worth calling attention to in response
to the frequent claims from the other side such events matter, when talking about warming. Even Obama was using the floods in, I think it was North
Dakota, as evidence of global warming. They weren't. You can't make that point if you're going to say, "the record low in June in Poughkeepsie (if
there was one) Matters"
Actually the thing which correlates best to radical, regional, weather variations is ocean changes (oscillations, El Nino, La Nina).
Another problem with arguing regional variations as proof of climate trends is it muddies the waters, as far as the argument short term trends of say
ten or more years matter.
I think they do matter. For one thing the one were in right now - no statistically significant warming for the last 15 years, flat-lining since 1997,
cooling since 2002 - wasn't supposed to happen according to the theory outlined by the IPCC, and others.
IPCC global temperature projections versus actual temperatures
James Hansen's for3cast for coming global temps in 1988 versus what actually happened was also incorrect.
If you look at a graph of what happened in the last 150 years or so, it wasn't a consistent rise. It was two 30 year trends which leveled out (step
funtions). 90 of those 150 years there was no warming.
So even though you can see this current short term trend were in of flat-lining, or cooling, as being dissolved into a long term trend of warming, you
can also see it as cause to wonder what's going to happen next.
Also if you cut away the BS, the global warming hysteria is really about a short term spike in temps from 1978 to 1998 - 20 years. Without that there
is no argument.
