I don't know where this number comes from, but Hansen's 1988 prediction
"Scenario B" was for approximately 2.6 C/century. The HADCRUT data
since 1988 show about a 1.9C/century increase. I do not think it is accurate
to say that one degree Celsius is on the high end of lastest estimates, unless
you are talking about a significantly shorter period than a century.

The current sea level rate is about 3 mm/year, and the rate will increase if
current warming trends continue.

I don't agree that the Midieval warm period was warmer than now. If you want to
say it was as warm as it was in 1900, I'd not argue, but that's a different

Given how much of the science is done by Michael Mann, and how he is
dismissed out of hand by many skeptics, I'll give a reference not
involving Mann.

The science tell us there is a problem. What do to about the problem is politics, and
with USA politics being banned from the list, I'll not discuss any of the solutions.
