The graph below plots the number of 40C readings at all GHCN HCN stations. The five hottest summers were 1934, 1936, 1954, 1980 and 1930. No summer above 350 PPM CO2 has come even close. The current summer will finish with the fewest 40C readings in 100 years.
NOAA claims that recent summers have been the hottest, because they are seeking funding and have no qualms about lying in order to obtain money.
And then there is Hansen, the ultimate climate disinformer.
We conclude that extreme heat waves, such as that in Texas and Oklahoma in 2011 and Moscow in 2010, were “caused” by global warming, because their likelihood was negligible prior to the recent rapid global warming.
