Now, a study published in the Indian Journal Current Science (reported here) -a paper by U R Rao, former chairman of Indian Space Research Organisation, released by Environment minister Jairam Ramesh.
"Consequently the contribution of increased CO2 emission to be observed global warming of 0.75 degree Celsius would only be 0.42 degree Celsius, considerably less than what predicted by IPCC," the paper said to be published in Indian Journal Current Science had said. This is about 44 % less than what IPCC had said.(Thanks to Marc Morano)
Ramesh in 2009 had released a similar scientific paper saying that the IPCC's claim that most Himalayan glaciers will melt by 2035 was wrong. A few months later, after a review the IPCC regretted the error. If Ramesh latest bid gets globally recognition, it can alter the rules of UN run climate negotiations of 200 nations.
Clegg, B.F., Clarke, G.H., Chipman, M.L., Chou, M., Walker, I.R., Tinner, W. and Hu, F.S. 2010. Six millennia of summer temperature variation based on midge analysis of lake sediments from Alaska. Quaternary Science Reviews 29: 3308-3316.
The results of the study are portrayed in the accompanying figure, where it can be seen, in the words of Clegg et al., that "a piecewise linear regression analysis identifies a significant change point at ca 4000 years before present (cal BP)," with "a decreasing trend after this point." And from 2500 cal BP to the present, there is a clear multi-centennial oscillation about the declining trend line, with its peaks and valleys defining the temporal locations of the Roman Warm Period, the Dark Ages Cold Period, the Medieval Warm Period, the Little Ice Age -- during which the coldest temperatures of the entire interglacial or Holocene were reached -- and, finally, the start of the Current Warm Period, which is still not expressed to any significant degree compared to the Medieval and Roman Warm Periods.
UPDATE 2 31/1/2010 From Energy Tribune.
Reluctantly, alarmists and their cheerleaders in the media changed their tune and the promise of warm and snowless winters with ‘global warming’ morphed into global warming means cold and snowy winters. ABC News even said cold and snowy winters would be the new norm because of global warming. Non sequiturs like that have sadly become ‘the new norm’ in the wacky world of the mainstream media.(From CO2 Science)
In Australia, the government’s Bureau of Meteorology and university alarmist scientists promised major drought and blocked dams and flood mitigation projects, but when devastating floods occurred this summer, they blamed that on global warming and again enviros and government agencies escaped the blame. Other scientists had warned that changes in the Pacific would lead to a return of the flood years like 1974, but they were ignored by agenda driven, green leaning government.
