Like I said reasonable people can disagree on where/how fast we are headed, and exact dates are squirrelly given the short-term variability in climate/weather patterns.
As an aside, many of the climate models made 20 years ago have been compared to measurements since then, and the scare part for at least SLR, which I am most well-versed in, is that we are trending towards the higher predictions.... Rahstorf et al out of Germany have numerous peer-reviewed papers on this.
Good primer here:

Bryan, I love nature, and I spend a lot more time in the woods, deep in the woods, than most.
You cannot tell me that the global freezing scare was one article. It wasn't. I remember very clearly.
If those models are accurate, why are none of the predictions coming true? Global warming changed very abruptly to 'climate change'.
And why isn't it valid to ask why Al Gore lives the way he does, if he believes what he claims to believe?
