By Bruce Melton PEArctic Sea Ice

The National Snow and Ice Data Center (NSIDC) report on March 19, 2015 shows Arctic sea ice has reached its lowest winter minimum on record. The record only goes back to 1979, but conclusions can be drawn from the record and global temperature that show global warming at work. This interactive chart is the NSIDC…

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.
