Chapter 2 IPCC WGI Fifth Assessment Report
Substantial losses in Arctic sea ice have been observed
since satellite records began, particularly at the time of the mimimum extent, which occurs in September at the end of the annual melt season. By contrast, the increase in Antarctic sea ice has been smaller.
Let’s have a look at that claim – which they published this week. Southern Hemisphere sea ice is one million km² above normal, and Northern Hemisphere sea ice is one million km² below normal. For most people who have completed first grade, one minus one equals zero. But not for the world’s top climate scientists, who apparently also don’t know how to use a spell checker.
