Dr Roy Spencer: "The Great Global Warming Blunder"

Must read

Dr Roy Spencer has written a book summarising the findings of his soon to be published (and peer-reviewed) work on probably the most important aspect of climate science: climate sensitivity:

The most obvious way for warming to be caused naturally is for small, natural fluctuations in the circulation patterns of the atmosphere and ocean to result in a 1% or 2% decrease in global cloud cover. Clouds are the Earth’s sunshade, and if cloud cover changes for any reason, you have global warming — or global cooling.

How could the experts have missed such a simple explanation? Because they have convinced themselves that only a temperature change can cause a cloud cover change, and not the other way around. The issue is one of causation. They have not accounted for cloud changes causing temperature changes.

The experts have simply mixed up cause and effect when observing how clouds and temperature vary. The book reveals a simple way to determine the direction of causation from satellite observations of global average temperature and cloud variations. And that new tool should fundamentally change how we view the climate system.

Blunder also addresses a second major mistake that results from ignoring the effect of natural cloud variations on temperature: it results in the illusion that the climate system is very sensitive. The experts claim that, since our climate system is very sensitive, then our carbon dioxide emissions are all that is needed to explain global warming. There is no need to look for alternative explanations.

But I show that the experts have merely reasoned themselves in a circle on this subject. When properly interpreted, our satellite observations actually reveal that the system is quite IN-sensitive. And an insensitive climate system means that nature does not really care whether you travel by jet, or how many hamburgers or steaks you eat.

Read Dr Spencer’s post here. A copy of the book is on its way to me right now, and a more detailed review will follow.

  1. Now I wonder if we’ll see it on the book show. Perhap’s Tony Jones will interview Dr Spencer on Lateline?
    My copy arrived today!
