Clouds in a Changing Climate

This a lecture by Dr Joel Norris from the Scripps Institution of Oceanography on the topic of Changing Clouds in a Changing Climate.

The lecture is a bit dull but it contains and explains some very important information.

What Dr Norris lays out in this talk is how important clouds are in driving the climate.

The effects of clouds on temperature are an order of magnitude greater than the effects of CO2.

Clouds can both increase the greenhouse effect and heat the planet (in the form of high Sirrus clouds) or decrease the greenhouse effect and cool the planet (in the form of low level clouds). The mechanisms of this are explained in the lecture.

Measuring the amounts of the different sorts of clouds and calculating their changes over time across the globe is fiendishly difficult.

There is no functional model of the global cloud system and this means that all the climate models essentially insert guesses into their calculations as to what CO2 warming will do to clouds.

All the alarmist models insert cloud assumptions based on a positive feedback mechanism via clouds meaning that the small CO2 warming trend will trigger a much larger and thus damaging warming trend via cloud changes. The science behind these models of clouds is so poor that this amounts to little more than a guess.
