More than 90% certain that climate change is being caused by human activity.
The Intergovernmental Panel on Climate Change (IPCC) said temperatures were probably going to increase by 1.8-4C (3.2-7.2F) by the end of the century.
It also projected that sea levels were most likely to rise by 28-43cm, and global warming was likely to influence the intensity of tropical storms.
The argument is all but over, now its time for action.
The IPCC aren't as enlightened as they want us to think.
There are MANY factors in climate change. Do we as humans have an effect? Probably some, but I don't think it's all due to us. There is a lot of evidence that the Milankovitch cycles (where the earth's axial tilt changes over time) are at a critical point just as they were at the end of the last ice age. Also, the sun's output overall seems to be increasing as of late (less than 1% but that's enough to make a few degrees change here) as well as sunspot activity.
I guess my point is this - sure, reduce emissions, but do it sensibly. If we don't we might find us destroying every major economy on the planet and living like Thoreau because we think we aren't doing enough, when in fact, only a portion of the change was due to us in the first place.
