Limits on CO2 Climate Forcing From Recent Temperature Data Of Earth
David H. Douglassa and John R. Christyb
Accepted by Energy and Environment Aug 2008
Abstract
The global atmospheric temperature anomalies of Earth reached a maximum
in 1998 which has not been exceeded during the subsequent 10 years. The
global anomalies are calculated from the average of climate effects
occurring in the tropical and the extratropical latitude bands. El
Niņo/La Niņa effects in the tropical band are shown to explain the 1998
maximum while variations in the background of the global anomalies
largely come from climate effects in the northern extratropics. These
effects do not have the signature associated with CO2 climate forcing.
However, the data show a small underlying positive trend that is
consistent with CO2 climate forcing with no-feedback.

"Niņo/La Niņa effects in the tropical band are shown to explain the
1998
maximum while variations in the background of the global anomalies
largely come from climate effects in the northern extratropics. These
effects do not have the signature associated with CO2 climate
forcing.

That is exactly what I have found but the so called "climate forcing"
could be simply due solubility effects.
