Dr Roy Spencer
The Great Global Warming Blunder
I have just finished reading this book.
Dr Roy, formerly a senior scientist for climate studies at NASA, is now a Professor at the University of Alabama in Huntsville where he leads the US science team for the Advanced MIcrowave Scanning Radiomoeter for EOS (AMSRE) on NASA’s Aqua stellite. He is co-developer of the original satellite method for precise monitoring of global temperatures from Earth-orbiting satellites.
Of course, I have been following Dr Roy’s website www.drroyspencer.com/2010/08/help-back-radiation-has-invaded-my-backyard/ for a long time and have found it an excellent resource for really getting the basics of climate science. Not only is Dr Roy at the cutting edge of empirical climate measurement technology he is also an excellent communicator of technical information in the most lucid of language that any interested layman can understand.
This book is about three things - CO2 as a greenhouse gas, the sensitivity of the climate to any source of warming or cooling and the Earth’s natural internally generated causes of climate variability - most notably the Pacific Decadal Oscillation (but also the other oceanic oscillations, too)
The main point of this book is that climate modellers have mistaken cause and effect in the behaviour of clouds. From his interpretation of satellite data and IPCC model inputs Dr Roy demonstrates that what is in fact the attenuating effect of clouds upon a temperature rise has been wrongly interpreted as a magnification - hence the gross over-estimation of the climate’s sensitivity. The climate is not balanced on a knife edge - the climate is pretty indifferent to a bit of warming or cooling!
The impact of extra CO2 from fossil fuel emissions alone is very small - estimated to be about 1degreeC for a doubling of CO2 ppm. The extravagant claims of climate apocalypse depend upon this initial tiny thermal imbalance in the climate system being grossly amplified by other factors.
Dr Roy spells out how clouds reduce the warming rather than amplifying it. He uses the analogy of a car heating up in the sun with the window initially half open. OPENING the window further as the temperature inside rises is the equivalent of NEGATIVE cloud feedback. CLOSING the car window as the temperature rises is the equivalent of the POSITIVE cloud feedback which the IPCC models have incorporated.
Then he goes on to show that natural variation can account for the majority of observed warming and cooling over the last century.
Dr Roy is bringing the findings of his peer-reviewed research direct to a lay public and a scientifically literate audience alike in the form of this book because his research has been ignored by the IPCC dominated orthodoxy for reasons he outlines.
Just put these details into the amazon.co.uk search
