So saith many people with tremendous expertise in this field and no political axe to grind. Forget Al Gore - he is not a scientist. Now, follow the money. Is there more money behind the research scientists (who are usually way under-funded by government grants) or the spokespeople for the fossil fuels industry?

What on earth is the possible motivation for the huge, global, cross-cultural scientific conspiracy that you deniers are proposing?

Guest_racer nails it above:
"We are burning millions of years of stored energy from the sun in a span of about 200 years"
How can that not have a huge effect?
