What would be the most compelling SCIENTIFIC FACT that convinced you that AGW will severely impact the earth?
Well you’re asking 2 different things. 1) Convincing fact that global warming will impact the Earth. 2) Convincing fact that AGW is a significant contribution to global warming. For #1, I think the most complelling fact is that we’re currently warming at a rate 20 times faster than when the planet naturally comes out of an ice age. From the coolest portion of the last ice age to when it reached the current stable temperature range, the planet warmed about 8°C in ~8,000 years (0.001°C per year). http://globalwarmingart.com/wiki/Image:I… Over the past 30 years the planet has warmed nearly 0.6°C (0.02°C per year). http://data.giss.nasa.gov/gistemp/graphs… Assuming this rate of warming continues – and there’s no reason to believe it won’t, unless we do something about it – I think it’s pretty obvious that warmin
