Analysis of new NASA AIRS study: 80% of U.S. Warming has been at Night

By Dr. Roy Spencer I have previously addressed the NASA study that concluded the AIRS satellite temperatures “verified global warming trends“. The AIRS is an infrared temperature sounding instrument on the NASA Aqua satellite, providing data since late 2002 (over 16 years). All results in that study, and presented here, are based upon infrared measurements alone, with…

The ‘trick’: How More Cooling Generates Global Warming

From the “we’ll fix that in post” department comes this from down under courtesy of Dr. Jennifer Marohasy. COOLING the past relative to the present has the general effect of making the present appear hotter – it is a way of generating more global warming for the same weather. The Bureau of Meteorology has rewritten…

Data analysis: Global temperature has not increased under Republican presidents, only Democrats

From the website Statistical Modeling, Causal Inference, and Social Science  at Columbia University comes this hilarious but real bit of data analysis. Looking at short trends in the global surface temperature data, the analysis shows that global temperature has not increased under Republican presidents, only Democrats. It’s probably spurious correlation, but still very entertaining. – Anthony…

It is worse than we thought – by Latitude

Guest essay by Sheldon Walker – (agree-to-disagree.com) The central objective of the Paris Agreement is its long-term temperature goal to hold global average temperature increase to “well below 2°C above preindustrial levels and pursuing efforts to limit the temperature increase to 1.5°C above pre-industrial levels”. Below, is an explanation of the different elements of this…
