“Polar bear territory is contracting” is a nonsense statement that is totally false. I dealt with a related claim here. Territory might be prophesied to contract decades from now but so far, it hasn’t changed a bit as a result of sea ice changes since 1950.
The alarming estimates from this new Nature paper, particularly as represented by the media, are grievously wrong both with respect to the amount of and the rate of sea level rise that might be associated with melting of the EIAS Totten glacier. There is unjustified author spin in the press releases and author’s interviews. There are underlying bad assumptions never mentioned except by reference to a previously refuted [here] bad paper by Rignot. A tangled web of deceit, to paraphrase a famous poem.
'To summarize, it looks like something like 55% of the modeling done in all of science is done in climate change science, even though it is a tiny fraction of the whole of science. Moreover, within climate change science almost all the research (97%) refers to modeling in some way. This simple analysis could be greatly refined, but given the hugely lopsided magnitude of the results it is unlikely that they would change much. Climate science appears to be obsessively focused on modeling.'
LA Times: A new study in the journal Nature has found that 80% of the U.S. population lives in counties experiencing more pleasant weather than they did 40 years ago. “Virtually all Americans are now experiencing the much milder winters that they typically prefer, and these mild winters have not been offset by markedly more uncomfortable summers or other negative changes,” write Patrick Egan, a political scientist at New York University, and Megan Mullin, professor of environmental politics at Duke University. It’s hard to complain about sunny days, but the researchers foresee a problem. If Americans think climate change has benefited their lives so far, they’ll have little motivation to demand action or overcome apathy in responding to global warming, the scientists write.
“I don’t think that I have been alarmist — maybe alarming, but I don’t think I’m an alarmist,” James Hansen, who used to head up NASA’s climate arm, told Yale Environment 360 in an interview republished in The Guardian Tuesday.
