The Island of Doubt

New Scientist has assembled a marvelous list of 26 of the most-cited objections to the scientific consensus on climate change. Temperatures rise before carbon dioxide; polar bear population is increasing; there is no consensus; it's all there. This handy-dandy resource -- the answers include source materials -- should be bookmarked. Here's the complete list:

• Human CO2 emissions are too tiny to matter

• We can't do anything about climate change

• The 'hockey stick' graph has been proven wrong

• Chaotic systems are not predictable

• We can't trust computer models of climate

• They predicted global cooling in the 1970s

• It's been far warmer in the past, what's the big deal?

• It's too cold where I live - warming will be great

• Global warming is down to the Sun, not humans

• It's all down to cosmic rays

• CO2 isn't the most important greenhouse gas

• The lower atmosphere is cooling, not warming

• Antarctica is getting cooler, not warmer, disproving global warming

• The oceans are cooling

• The cooling after 1940 shows CO2 does not cause warming

• It was warmer during the Medieval period, with vineyards in England

• We are simply recovering from the Little Ice Age

• Warming will cause an ice age in Europe

• Ice cores show CO2 increases lag behind temperature rises, disproving the link to global warming

• Ice cores show CO2 rising as temperatures fell

• Mars and Pluto are warming too

• Many leading scientists question climate change

• It's all a conspiracy

• Hurricane Katrina was caused by global warming

• Higher CO2 levels will boost plant growth and food production

• Polar bear numbers are increasing

And again, the answers are here.
