Global Warming? Apparently Not in Greenland
The 1950s saw the hottest Greenland in about 800 years and it is colder now than the 50s. Greenland during the Midevil Warm Period had periods warmer than any other recorded era. In the 1950s temperatures in Greenland approached those of the MWP but Greenland has been** colder ever since.*
So if the temperature is lower and the glaciers are melting anyway that would support my claim that soot, not CO2, is driving the meltdown.
