The silicate + CO2 - > different silicate + carbonate chemical weathering rate tends to
increase with temperature globally, and so is a negative feedback (but is too slow to damp out short term changes)-- but chemical weathering is also affected by vegetation, land area, and terrain (and minerology, though I'm not sure how much that varies among entire mountain ranges or climate zones)-- ie mountanous regions which are
in the vicinity of a
warm rainy climate are ideal for enhancing chemical weathering (
see Appalachians
in the Paleozoic, more recently the Himalayas).

in the ancient past.

Absorption of thermal radiation cools the thermal spectra of the earth as
seen from space, radiation emitted by de-excitation is what results
in the further
warming of the surface, and the surface continues to
warm until the rate at which energy is radiated from the earth's climate system (given the
increased opacity of the atmosphere to longwave radiation) is equal to the rate at which energy enters it.

increase south and southwest of Greenland also

I don't think it's on its face unreasonable for Trenberth to point to the 2004 North Atlantic and (the even nastier, although it didn't get much play
in the US media) East Pacific seasons, plus the anomalous hurricane
in what I guess we now must call the South Atlantic season, and speculate as to whether there might not be a climate connection and that
in any case this is the sort of thing we're likely to
see with
increased warming.
I've been to the Arctic three times for the newspaper since 2003 — visiting the North Slope, North Pole, and Greenland to examine what mix of human and natural forces is driving the

in a region increasingly
seen as a resource trove and shortcut for shipping.
In a region where the ocean was already being heated, the same pattern would be
seen but now since the skin SST was

in Japan gumming up the wind system.
Higher clouds are an expected effect of
warming, and to first order, independent of GCRs —
see ftp://eos.atmos.washington.edu/pub/breth/papers/2007/Zhu-etal-LowCldClimSens-JGR-2007.pdf Note the
increase in high clouds (Fig2b3) and decrease
in low clouds (Fig2e1) downwind of S America
in the equatorial trade winds..
In terms of the aerosols: If you want to argue really simplistic, you could still explain what is seen in Dave's NH - SH time series: due to the larger thermal inertia of the SH, you would expect slower warming there with greenhouse gas forcing, so an increase in NH - SH early on, which would then be reduced as aerosol forcing becomes stronger in the N

increasing there is presumably an absolute

see how the system is changing.
Does this explain why the Solar can seem to account for the full measured 0.8 C
increase in global temperature (
see # 126), BUT the GCMs say that GHG
warming should be 5 times larger than solar (1.5 vs 0.3 forcing -
see Hansen et al above at the top.)
