Recent investigations suggest most extinctions have occurred at the hot

the reference is wishy-washy...)

There have also been extinctions at the cold points, including our
near relatives the neanderthals, who failed to survive the last ice
age!

On the micro-climate scale, people round here are glad of a
winter cold spell - to extinguish the noxious pests, if only temporarily.

Ya tell that to the Vikings that got forced out of farming Iceland in
the 14 century, who caused that?

I was looking forward some nice Mediterranean type weather for the UK
by now, due to global warming. In practice it seems to be colder
wetter and snowier. What went wrong?

Expect the naysayers to say nay, and the doom-mongers to
say "woe woe and thrice woe" or (in a Scots accent) "we're all
doomed, doomed" ;}

I was shocked when somebody showed me that the UK is approximately on
Siberian latitudes, so that there is supposed to be some warm flow that
keeps it bearable - but that flow is not immutable, apparently...

I started reading at his home page, which appears to have good material

The way I look at it, the burden of proof is on the researcher to
prove the theory which upsets the status quo, in this case AGW.
However, I believe that burden also includes providing every
opportunity for his skeptics to prove him wrong by checking his
assumptions, raw data, reasoning, models, results and conclusions.

I'm all for transparency, but there are limits: "Every opportunity" is
very open ended, and can lead to the scientist spending most of his time
dealing with requests for more and more information, and more and more
help understanding it, and more and more help running the models. You
may not know the people requesting all this information and all this
help expect it for *free*.

The standard, instead, are the papers he produces. If they are good
ones, they will provide the evidence needed. If the papers don't do
that, they may not get published, or if they are, then they don't get
much attention, are not cited very often, and the scientist finds
himself in the professional dust bin.

Besides, the raw data is available (and other resources), and nothing
should stop another person from devising his own theories, developing
his own models, and ultimately writing papers that don't have the
"flaws" he was complaining about. Some have done this, with varying
degrees of success.
These responsibilities are amplified by the rush to public policy and
the extreme costs of such policy. In my view this is absolutely
required.

There is no rush. The potential for climate problems began to be
understood in the '70's, and the science is far better now. It may seem
like there is a rush because we've delayed taking action sooner when the
problem was smaller.

Very clearly shown in the the 0degree isotherm for January, see
http://etc.usf.edu/Maps/pages/3000/3031/3031.jpg

Also consider that the "polar bear capital of Canada" is at the
same latitude as the south of England.
