Arguments by Plimer	vs	What the Science Says
"CO2 limits will harm the economy"		The benefits of a price on carbon outweigh the costs several times over.
"CO2 was higher in the past"		Climate has changed along with CO2 levels through geological time.
"Global warming stopped in ~~1998~~, ~~1995~~, ~~2002~~, ~~2007~~, ~~2010~~, ????"		Global temperature is still rising and 2010 was the hottest recorded.
"Human CO2 is a tiny % of CO2 emissions"		The natural cycle adds and removes CO2 to keep a balance; humans add extra CO2 without removing any.
"IPCC ‘disappeared’ the Medieval Warm Period"		The IPCC simply updated their temperature history graphs to show the best data available at the time.
"It warmed just as fast in 1860-1880 and 1910-1940"		The warming trend over 1970 to 2001 is greater than warming from both 1860 to 1880 and 1910 to 1940.
"It's a natural cycle"		No known natural forcing fits the fingerprints of observed warming except anthropogenic greenhouse gases.
"It's cooling"		All the indicators show that global warming is still happening.
"It's not bad"		Negative impacts of global warming on agriculture, health & environment far outweigh any positives.
"It's not us"		Multiple sets of independent observations find a human fingerprint on climate change.
"It's the sun"		In the last 35 years of global warming, sun and climate have been going in opposite directions
"Models are unreliable"		Models successfully reproduce temperatures since 1900 globally, by land, in the air and the ocean.
"Ocean acidification isn't serious"		Ocean acidification threatens entire marine food chains.
"Positive feedback means runaway warming"		Positive feedback won't lead to runaway warming; diminishing returns on feedback cycles limit the amplification.
"There is no consensus"		97% of climate experts agree humans are causing global warming.
"Volcanoes emit more CO2 than humans"		Humans emit 100 times more CO2 than volcanoes.
"We're coming out of the Little Ice Age"		Scientists have determined that the factors which caused the Little Ice Age cooling are not currently causing global warming.
