Scary Halloween Edition : Geophysical Research Letters

By Bruce Melton PEArctic Sea Ice

Geophysical Research Letters had a busy and scary Halloween edition. As discussed below on October 2, satellite analysis of 2008 Arctic sea ice thickness has revealed the lowest volume of Arctic sea ice ever recorded. Smedsrud, et. al., Recent and future changes of the Arctic sea-ice cover has a new model based on the latest…

Remember, average global warming over land is double the global average because of the cooling influence of our oceans and ice sheets, or 3.56 degrees C in December (6.4 F). and the average over the arctic is four times the global average or 7.12 C (12.8 F). Importantly, the increase in extreme temperature is far greater than the average, and extreme weather increases nonlinearly because of the basics of heat and energy physics, where a little warming does not create a little more extremeness in the weather, it creates a lot more.
