Why Does Arctic Sea Ice Respond More Evidently than Antarctic Sea Ice to Climate Change?
The current climate change episode has impacted sea ice in the 2 polar regions differently. In the Arctic, remarkable sea ice extent and thickness declines have been observed with a stunning depletion rate of old ice. No similar changes have been observed in the Antarctic. In this paper, the questio...

The current climate change episode has impacted sea ice in the 2 polar regions differently.
