Climate Myth	What the Science Says
"[we should not] persuade the world to impoverish itself by moving from relatively cheap carbon-based energy to much more expensive non-carbon energy." 29 November 2011 (Source)	When you account for all of the costs associated with burning coal and other fossil fuels, like air pollution and health effects, in reality they are significantly more expensive than most renewable energy sources.
"if there is a resumption of warming, the only rational course is to adapt to it, rather than to try (happily a lost cause) to persuade the world to impoverish itself " 29 November 2011 (Source)	The benefits of a price on carbon outweigh the costs several times over.
"so far this century both the UK Met Office and the World Meteorological Office confirm that there has been no further global warming at all." 29 November 2011 (Source)	Global temperature is still rising and 2010 was the hottest recorded.
"recent research findings show that the increased evaporation from the Arctic ocean, as a result of warming, will cause there to be more cloud cover, thus counteracting the adverse effect he is so concerned about." 29 November 2011 (Source)	Evidence is building that net cloud feedback is likely positive and unlikely to be strongly negative.
"the polar bear population has not been falling, but rising." 29 November 2011 (Source)	Polar bears are in danger of extinction as well as many other species.
"while satellite observations do indeed confirm that the extent of arctic sea ice has been declining over the past 30 years, the same satellite observations show that, overall, Antarctic sea ice has been expanding over the same period." 29 November 2011 (Source)	Arctic sea ice loss is three times greater than Antarctic sea ice gain.
"Although its now famous “hockey stick” chart of temperatures over the last millennium, which inter alia featured prominently in the UK Government’s 2003 Energy White Paper, is almost certainly a myth, the IPCC refuses to entertain any challenge to it" 29 March 2011 (Source)	Recent studies agree that recent global temperatures are unprecedented in the last 1000 years.
"The IPCC’s consistent refusal to entertain any dissent, however well researched, which challenges its assumptions, is profoundly unscientific. " 29 March 2011 (Source)	Numerous papers have documented how IPCC predictions are more likely to underestimate the climate response.
"Clearly carbon dioxide is a greenhouse gas – not the most important greenhouse gas – clearly it’s a greenhouse gas, and clearly, other things being equal, it will have a warming effect, and we all know emissions are rising fast and therefore concentrations are rising fast – that’s clear, no dispute about that. But there is considerable uncertainty about whether other things are equal, and there’s a lot of climate science on that at the moment. There’s also uncertainty as to how big the warming effect is – to use the technical term, how great the climate sensitivity of carbon is. And there’s a lot of dispute about that. It depends for example on the science of clouds, whether they are a positive feedback to amplify warming or whether they’re not, and the climate science community are divided on that. " 1 November 2010 (Source)	Net positive feedback is confirmed by many different lines of evidence.
"While CO2 is indeed a greenhouse gas, increasing concentrations of which may be expected to have (other things being equal) a warming effect, scientists disagree about how large that effect may be (this is particularly affected by ignorance of the effect of clouds). And, of course, other things may not be equal: there is much in climate science that remains unknown. " 1 July 2010 (Source)	That human CO2 is causing global warming is known with high certainty & confirmed by observations.
"On the science, I think that you are clearly right that the science is far from certain, it is very uncertain, and the more you look at it the clearer that is the case, it is certainly the case that carbon dioxide concentrations in the atmosphere have been increasing rapidly that carbon dioxide is a greenhouse gas. Not the most important one but it is a greenhouse gas, and that prima facia you would expect it to have some warming effect." 1 June 2010 (Source)	Rising carbon dioxide drives global warming. The greenhouse effect from water vapour amplifies carbon dioxide warming - a strong positive feedback.
"Whether it [C02] is a major or minor contribution to [global] warming is extremely uncertain, the scientists don’t really know." 1 March 2010 (Source)	Theory, models and direct measurement confirm CO2 is currently the main driver of climate change.
"All true scientists in this field say there is enormous doubt, enormous uncertainty, it is very very slight warming in last quarter of the 20thCentury but no further warming in this century from official Met Office figures. The acid test is temperature, that is what all of the scientists agree. The only reason this becomes an issue is because of the slight rise in temperature in the last half of the Twentieth Century." 1 March 2010 (Source)	Every part of the Earth's climate system has continued warming since 1998, with 2015 shattering temperature records.
"Certainly, it is curious that, whereas their models predicted an acceleration in global warming this century as the growth in emissions accelerated, so far this century there has been no further warming at all." 23 November 2009 (Source)	There are many lines of evidence indicating global warming is unequivocal.
