The Sunday London Telegraph reports that when the UN's Intergovernmental Panel on Climate Change (IPCC) releases its upcoming report this February, they will downgrade their estimates of man's role in global warming by 25%. The Telegraph says that the report will reduce its estimate of man's role in global warming by 25 percent. However, the IPCC will still project global temperatures to climb by 4.5 C during the next century and rising sea levels, albeit by half the amount -- 17 inches instead of 34 inches by 2100 -- forecast by the IPCC's 2001 report.
The report will also claim that atmospheric carbon dioxide levels have indeed continued to climb over the past five years but that the overall human effect on global warming since the industrial revolution has been dampened by cooling caused by particulate matter and aerosol sprays, which accumulate in the upper atmosphere and reflect heat from the sun.
The UN will explain that the findings are the result of more refined estimates based on new data rather than "a reduction in the risk posed by global warming." The reduced anthropologic impact on climate change is expected to produce ammunition for newly-emboldened global warming skeptics who've recently been beleagured by proponents of anthropomorphic global warming.
Climate change has occured throughout human history. Historical records show that grapes grew in England as recently as 650 years ago, requiring much warmer temperatures than we have now. Global temperatures have been estimated to have been even warmer than that 2,000 years ago, during the early years of the first Millenium AD.
In between that point, especially during the Middle Ages Europe's temperatures sunk to some of the lowest in recorded human history.
