The journalist George Monbiot has challenged climate change denialist, Professor Ian Plimer, to a ‘dual’. Monbiot has taken issue with a number of points made in Plimer’s book, Heaven and Earth, and seeks clarification on them in writing before a public debate begins. Here is a sample of points made in Plimer’s book that Monbiot, quite rightly, questions:
“the last two years of global cooling have erased nearly thirty years of temperature increase.”
“NASA now states that […] the warmest year was 1934.”
“the sea ice has expanded”
“If the current atmospheric CO2 content of 380 ppmv were doubled to 760 ppmv […] [a]n increase of 0.5C is likely”
“About 98% of the greenhouse effect in the atmosphere is due to water vapour.”
“satellites and radiosondes show that there is no global warming.”
“The Hadley Centre in the UK has shown that warming stopped in 1998″
“Volcanoes produce more CO2 than the world’s cars and industries combined.”
“termite methane emissions are 20 times potent than human CO2 emissions”.
