A few people at NOAA understand that recent warming is just background noise in the long term picture, and that Michael Mann’s hockey stick is meaningless junk science.
But they have a fundamental gap in their knowledge of science.
These older records show that climate has changed abruptly in the past, and also reveal a remarkable correspondence between carbon dioxide change and temperature change
Every geologist knows that CO2 solubility in the oceans varies with ocean temperature. When the oceans warm up, they outgas CO2. Thus a warming ocean increases atmospheric CO2, and a cooling climate decreases atmospheric CO2.
In the historical record, CO2 is a response to warming – not a driver of warming. Because climate scientists don’t understand this most fundamental scientific fact, they have built up an entire body of superstition based peer-reviewed science.
