We are not accelerating ANYTHING..... Haven't you read ALREADY that ALL green biomass of Earth NEEDS AND CRAVES for atmospheric CO2?....
Haven't you read the dozens, upon dozens of links, and research that SHOWS CO2 changes do not coincide with temperature changes?....on the contrary CO2 lags an average 800 years, sometimes it is longer, and somtimes less, but it ALWAYS lags temperature changes...
Even in longer periods of millions of years you can see that SEVERAL times temperatures were higher and CO2 was lower, and vice versa...
Even during the continuing Climate Change, which is natural, the Earth began to warm for most of the world in the 1600s, but in some parts it began to warm in the 1500s, and then in the 1860s was when CO2 began to slowly increase at first, temperatures continued to incrase, and CO2 took longer to increase.....
There is NO EVIDENCE but flawed computer models which claim that CO2 causes the warming claimed by the AGWers, and it is a FACT that GCMs are flawed....

Geographically distributed predictions of future climate, obtained through climate models, are widely used in hydrology and many other disciplines, typically without assessing their reliability. Here we compare the output of various models to temperature and precipitation observations from eight stations with long (over 100 years) records from around the globe. The results show that models perform poorly, even at a climatic (30-year) scale. Thus local model projections cannot be credible, whereas a common argument that models can perform better at larger spatial scales is unsupported.

Abstract Observations from the International Satellite Cloud Climatalogy Project (ISCCP) are used to demonstrate that the 19-level HadAM3 version of the United Kingdom Met Office Unified Model does not simulate sufficient high cloud over land. By using low-altitude winds, from the European Centre for Medium Range Weather Forecasting (ECMWF) Re-Analysis from 1979 to 1994 (ERA-15) to predict the areas of maximum likelihood of orographic wave generation, it is shown that much of the deficiency is likely to be due to the lack of a representation of the orographic cirrus generated by sub-grid scale orography. It is probable that this is a problem in most GCMs.

The widely accepted (albeit unproven) theory that manmade global warming will accelerate itself by creating more heat-trapping clouds is challenged this month in new research from The University of Alabama in Huntsville.
Instead of creating more clouds, individual tropical warming cycles that served as proxies for global warming saw a decrease in the coverage of heat-trapping cirrus clouds, says Dr. Roy Spencer, a principal research scientist in UAHuntsville's Earth System Science Center.
That was not what he expected to find.
"All leading climate models forecast that as the atmosphere warms there should be an increase in high altitude cirrus clouds, which would amplify any warming caused by manmade greenhouse gases," he said. "That amplification is a positive feedback. What we found in month-to-month fluctuations of the tropical climate system was a strongly negative feedback. As the tropical atmosphere warms, cirrus clouds decrease. That allows more infrared heat to escape from the atmosphere to outer space."
The results of this research were published today in the American Geophysical Union's "Geophysical Research Letters" on-line edition. The paper was co-authored by UAHuntsville's Dr. John R. Christy and Dr. W. Danny Braswell, and Dr. Justin Hnilo of Lawrence Livermore National Laboratory, Livermore, CA.
