Why the temperature increases are higher at the poles? You have asked a very good question.

I always took for granted that the answer was simple and straightforward until you asked and I thought about it. Bottomline = I do not know, but the increase is already ca 8ºC in the polar areas compared with ca 1ºC worldwide.

More than 10 years ago, the Inuits were convinced(my personal conversations)about global warming on the basis of their life experiences and were wondering why we could not get out act together down here.

Today's (Tuesday) NYT has an article about it.

<http://www.nytimes.com/interactive/2007/10/01/science/20071002_ARCTIC_GR
APHIC.html?th&emc=th>

The October issue of the National Geographic also covers it under "Who
own the Arctic?"

I have never before seen (from the air) so much pack ice NE of Iceland as
this summer, and that certainly supports the idea of accelerated breakup
of the Arctic ice cap.  The global-warming temperature increases at the
poles are far greater than those further south.

I hope that politicians and other deniers can get real and read some
reliable sources rather than living in a "separate reality" where global
warming is concerned.
