NASA created a very detailed animation of global warming since 1880.
There is an incredible amount of misinformation in this video. The first problem is that it starts in 1884, not 1880. But the real problem is that much of their land data is not from any known source.
I overlaid the land coverage of GISS 1884 (green below) on the animation frame from 1884. Note the great detail in the animation over Africa, South America, and central Asia – where they had no data. In Antarctica they had no data at all, yet drew in a tremendous amount of completely fraudulent detail! The first land based exploration of Antarctica didn’t even occur until 1892. Outside of Australia, they only had three or four land based thermometers in the entire southern hemisphere.
They must be using 5,000 km smoothing with highly detailed imaginary sub-smoothing.
