Is the sun to blame?
Global warming is down to the Sun, not humans
It's all down to cosmic rays
Does CO2 cause warming?
Human CO2 emissions are too tiny to matter
CO2 isn't the most important greenhouse gas
Ice cores show CO2 increases lag behind temperature rises, disproving the link to global warming
Ice cores show CO2 rising as temperatures fell
The cooling after 1940 shows CO2 does not cause warming
What happened in the past?
The 'hockey stick' graph has been proven wrong
It's been far warmer in the past, what's the big deal?
It was warmer during the Medieval period, with vineyards in England

What is happening now?
Mars and Pluto are warming too
Antarctica is getting cooler, not warmer, disproving global warming
Polar bear numbers are increasing
The lower atmosphere is cooling, not warming
The oceans are cooling
Global warming stopped in 1998
What is going to happen?
Warming will cause an ice age in Europe
Higher CO2 levels will boost plant growth and food production
Hurricane Katrina was caused by global warming
Why should I worry?
It's too cold where I live - warming will be great
We can't do anything about climate change
