Even More About the Arctic Ocean Ice Cap
Labels: Science; Global Warming
Isn't the question how thick is the ice? The fact that the area of ice is equvalent to other winters is not as relevant as the thickness of the ice. i.e Thinner ice melts in th esummer and thick ice does not.
I am also hearing reports that the permafrost is melting.
I hear too that permafrost in Alaska is indeed melting. I believe that is mainly because the northern hemisphere has gotten a little warmer this past 150 years. No word on Siberia or Canada, however. Not a bad thing in my book, but my knowledge is limited.
Once you get far enough north for permafrost, you need it as much infrastructure is built directly on it under the supposition that it is stable.
I heard on Pulse of the Planet during the last week that melting permafrost releases tremendous amount sof carbon into the atmosphere.
