Ok, so I am punting a topic, but there's a valid addition to the discussion:
This August's Scientific American issue talks covers Global Warming, five writers are in on it.
At the end of a paragraph at the end of the page 72 text, it is noted in two sentences, that in spring-2007, a major research announcement found that the rate of "atmospheric forcing causing warming" for 2000-2004 was
triple the rate found in the decade 1990-2000.
The current IPCC findings for warming, and for crisis warnings, were based on the lower 1990-2000 observed rates.
So is this just another spike in the noise, or is
this piece of data really unprecedented, for once? Or is this piece of data no more conclusive than everything we've seen so far either?
"But the IPCC scientists made their assessment before a study published online this past April in the 'Proceedings of the National Academy of Sciences USA' reported the worldwide carbon dioxide emissions between 2000-2004 increased at three times the rate of the 1990s -- from 1.1 to 3.2 percent a year. In other words, the actual global emissions since 2000 grew faster than those projected in the highest of the scenarios developed by the IPCC.
That research indicates that the situation is more dire than even the bleak IPCC assessment forecasts."
