There was one absolute blatant lie in the article. It said the ice cores showed increased CO2 and then increased temperatures. It is actually the reverse. Temperature increased and then CO2 increased. Anyone can verify this by looking up the research on the Vostok Ice Cores.
They were not mistaken nor did they make an error. They lied in an attempt to give support to AGW theory. The ocean is the largest repository of unbound CO2. The solubility of CO2 is a function of the temperature of the ocean. When the temperature increase the solubility decreases and thus increased CO2 levels.
The article lies.
I completely agree. A rise in water temperature brings CO2 out of solution. It was orbital mechanics which caused a rise in atmospheric temperatures, melting ice and a rise in CO2 as the oceans warmed. They need to explain how a glacially-cold ocean releases CO2 out of solution. It doesn’t. It traps CO2.
Bad science.
