Wondering where things stand on global warming? Let’s go to the science of it. And by “science” I mean physical observations. Nothing complicated. What do thermometers say? What’s happening with polar ice caps? And carbon dioxide?
In the following analysis I use publicly available data as provided by government scientists at places like NASA, the U.K. Met office, and NOAA. This is the data we’re told to use and trust. I’m using it and trusting it.
Measured Temperatures. The two charts below show recent global temperatures (NASA/GISS data) in units of hundredths of a degree above the 1951-1980 average. The lines are linear regression trends for the extent shown. March 2012 was the most recent month of data at the time of writing.
