I think what he is trying to say is that it is warming up faster that earlier evidence shows, and that the reasons are different from previous warming periods.

Basically. There have been periods during the glacial/interglacial transitions when there were very fast, very large changes (notably at the termination of the Younger Dryas). But the current rate of change within a stable interglacial appears highly unusual (bordering on unprecedented, as far as can be ascertained from data with insufficient temporal resolution to be sure), and the main forcing, increasing atmospheric CO2 during a warm interglacial phase, is indeed different than seen in the ice core record.

So this is hardly unprecedented. :-)

My, my, my.

You're in my field of expertise, now. The 'Y2k computer crash' story was a hoax. Complete hoax. And was proven wrong. Completely.

But somehow, it is comforting to see you pushing that story too . . .
