Quote:He ignored sea ice formation in the Artic.

So what? He was still right in what he said. The Arctic sea ice is a different subject. If you want to take them together, sometimes the total area is below the average, sometimes above. The difference is insignificant.




You might note that the alarmists "ignore" the Antarctic when they carry their End of the World signs.

Quote:U know, the earth hasn't always had ice caps at the poles. And the raw data from the ice cores doesn't show direct correlation between co2 and surface temps

Quote:I can't take you seriously because you don't even have a basic understanding of the science.


Changes in sea ice significantly modulate climate change because of its high reflective and strong insulating nature. In contrast to Arctic sea ice, sea ice surrounding Antarctica has expanded1, with record extent2 in 2010. This ice expansion has previously been attributed to dynamical atmospheric changes that induce atmospheric cooling3. Here we show that accelerated basal melting of Antarctic ice shelves is likely to have contributed significantly to sea-ice expansion. Specifically, we present observations indicating that melt water from Antarctica’s ice shelves accumulates in a cool and fresh surface layer that shields the surface ocean from the warmer deeper waters that are melting the ice shelves. Simulating
these processes in a coupled climate model we find that cool and fresh surface water from ice-shelf melt indeed leads to expanding sea ice in austral autumn and winter. This powerful negative feedback counteracts Southern Hemispheric atmospheric warming. Although changes in atmospheric dynamics most likely govern regional sea-ice trends4, our analyses indicate that the overall sea-ice trend is dominated by increased ice-shelf melt. We suggest that cool sea surface temperatures around Antarctica could offset projected snowfall increases in Antarctica, with implications for estimates of future sea-level rise.
