John Cook’s Logical Flaw

HadCRUT temperatures  (black line) plotted vs. ENSO. Warming occurs when ENSO is positive.

Cook believes that CO2 “controls the climate” – because CO2 is changing and the climate is changing.

There are several logical fallacies with his belief system.

1. The climate always changes, regardless of what CO2 is doing
2. Lots of things affecting the climate are changing, besides CO2
3. Until climatologists understand what caused past climate change, they certainly can’t claim to know that current climate change is different.

The 1910-1940 warming was nearly identical to the 1975-2000 warming. Blaming the 1975-2000 warming on CO2 isn’t going to fly. It was due primarily to the PDO shift in the mid-1970s.
