The UN's IPCC claim that large modern consumer/industrial CO2 emissions are causing maximum temperatures to increase across the globe proves to be without any empirical and scientific merit.....NOAA's NCDC division documents U.S. maximum temperatures are exhibiting a declining trend, not catastrophic "global warming"...
The adjacent chart is a fairly simple plot of the 20 hottest U.S. months, with the corresponding atmospheric CO2 level (black dots) for the respective month.
As the latest NOAA empirical dataset clearly indicates:
===> The hottest U.S. months took place during the 1930s, a very low CO2 period
===> The huge growth of atmospheric CO2 levels after 1949 did not produce the predicted increase of catastrophic, ever higher temperatures
===> The average maximum record temperature prior to 1950 (the 10 highest months of 1895-1949) was higher than the average maximum record temperature post 1950 (the 10 highest months of 1950-2014)
===> Despite the massive human CO2 emissions, maximum temperatures reveal a cooling trend of highs since 1950
This NOAA factual evidence for the continental U.S. confirms what has previously reported for maximum temperatures across the globe.
Note1: My bad. Found dumb error on original chart. Now corrected. No corrections to above text required.
Note2: NOAA U.S. temperature dataset and Excel used to produce above chart. Hey, don't know how to chart in Excel? It's easy to produce charts - you can do it too! Go here to learn how.
