In 1999, NASA showed that the 1930's were the hottest period in the US.
In 2019, NASA showed the same period of temperature data but they now showed temperatures in the 1990's exceeded the 1930's!!!!
Recent headlines have said that July was the hottest world temperature on record. The only problem is, except for the US (and some data in Europe and Australia), the CLIMATE ALARMISTS have no useful data. That means ALL of their gloom and doom stories are using computer generated data that shows it was cooler when CO2 was lower! In other words, these psycho liars have NOTHING to prove their headlines are correct. See REALCLIMATESCIENCE dot COM to see the data.
