Useful discussion of the climate change debate
This well-researched book examines the claims that we must cut our CO2 emissions to save the planet. Wishart points out that the Medieval warm period, 800-1300, was 1-2 degrees C warmer than the 20th century. Michael Mann, who provided Al Gore with the 'hockey-stick' graph which supposedly proved that the 20th century was the warmest ever, now admits, "the mid 20th century was comparable in warmth, by most estimates, to peak Medieval warmth (i.e. the so-called 'Medieval Warm Period')."Was this review helpful?

The New Scientist states, "Solar forcing may have been largely responsible for warming in the late 19th and early 20th century, levelling off during the mid-century cooling." The earth indeed cooled between 1945 and 1976, despite record GDP growth of more than 4% a year and rising CO2 levels.
A 2009 article in Geophysical Research Letters said, "Increasing Total Solar Irradiance between 1980 and 2000 could have contributed significantly to global warming." The 2004 Symposium of the International Astronomical Union agreed that the sun caused most of this warming. It also concluded that the sun's activity would soon lessen and so that the earth would again start to cool (as it has done since 1998). Between January 2007 and February 2008, the earth's temperature fell by 0.59 degrees C (the Met Office's Hadley Centre's figure), or 0.75 degrees C (the Goddard Institute of Space Studies' figure).
On estimates of sea-levels by 2100, the journal Science said, "increases of two metres are physically untenable." The Intergovernmental Panel on Climate Change's Fourth Assessment Report estimates a rise of 13 centimetres by 2100, dropping its earlier estimate of 30 centimetres. Al Gore said six metres!
Antarctica's temperature averages 46 degrees C below zero. So, unsurprisingly, it is not melting or warming: in fact, it has been gaining ice and cooling since 1980. The Arctic is losing ice, but overall sea ice levels are nearly the same as they were in 1979.
Wishart shows how giant corporations and the EU use climate change to profit from emissions trading schemes. Enron and George Soros both fund green groups.
