Sentences with phrase «because global ice»

He will not glean any disunity because the contributors to this forum are by and large scientists who understand the psychics behind global warming as thoroughly and well as; why does ice expand when heated; or why can warm atmosphere hold more water vapour than cold.

Arctic sea ice is a key indicator of global climate change because of its sensitivity to warming and its role in amplifying climate change through the SIAF.

«Global ice» does have a long term decline, but because of the out of phase seasons in each hemisphere, and the large interannual variability — particularly in the south, it isn't a reliable guide to what is going on with the climate.

Every now and again, the myth that «we shouldn't believe global warming predictions now, because in the 1970's they were predicting an ice age and / or cooling» surfaces.

Ken Drinkwater, one of a team of scientists at the Institute of Marine Research in Bergen who have been observing the Arctic for decades, dismisses the idea that the ice is melting because of any rise in global temperatures.

«The Interior Department declared the polar bear a threatened species Wednesday, saying it must be protected because of the decline in Arctic sea ice from global warming.»

At the hemispheric - mean scale, the «Little Ice Age» is only a moderate cooling because larger offsetting regional patterns of temperature change (both warm and cold) tend to cancel in a hemispheric or global mean.

I can't wait for the explanations when that happens — as in that movie «The Day After,» in which it is revealed that global warming actually leads to an ice age because the Gulf Stream gets re-routed and no longer warms the North Sea.

AGW «science» predicted that Antarctic continental ice would increase because of more precipitaion due to global warming, not sea ice extent.

In this regard, I would observe that at least one important AGW effect, rising sea level, does not depend on a specific regional outcome so much as on global mean T.
