I generally think anthropogenic climate change exists, and that it represents a real danger to the earth. But I've seen a lot of research on it that basically says that the CO2 emissions from human activity are not significant and that many current studies and a lot of current data is either invalid, exaggerated, or wrong.
Another argument that I've used in the past, but I am now less sure of, is that there is a complete global consensus that anthropogenic climate change exists. I know there is a consensus, sure, but that in and of itself doesn't mean much if there is conflict within fields, and times do change. 50 years ago or so there was a scientific consensus that dietary cholesterol and saturated fats directly caused or were directly correlated with heart disease and obesity, conclusions that are now challenged as, if not outright wrong, at the very least highly flawed.
So, /sci/, present your arguments. I'm open-minded and want to know what you guys have to say.
This article was posted yesterday and really made me think. Specific refutations/support for the article would be nice.http://folk.uio.no/tomvs/esef/Jaworowski%20CO2%20EIR%202007.pdf
