The New York Times ran this story ten years ago, using pristine data from Mohonk, NY to prove that the world was heating out of control.
The Mohonk station shows that the world began to heat out of control after the year 1980, and that the frequency of hot days has skyrocketed.
Scary stuff! We probably need to invoke immediate world communism to stop this warming. Except for one minor problem. The Mohonk data doesn’t agree with the other stations in New York, which show the 1950s as the warmest decade and the frequency of hot days declining.
Same story for the entire Northeastern US. The post-1980 warming shown at Mohonk doesn’t exist, and the period around 1950 was the warmest.
Sea level rise rates also peaked around 1950 at New York.
I have no idea what is wrong with the Mohonk data, but every indication is that is defective – just like New York Times reporting.
