Is Global Warming a natural cycle of our planet?
At the request of the U.S. Congress, a special “Committee on Surface Temperature Reconstructions for the Past 2,000 Years” was assembled by the National Research Council’s Board on Atmospheric Sciences and Climate. The Committee consisted of 12 scientists from different disciplines and was tasked with explaining the current scientific information on the temperature record for the past two millennia, and identifying the main areas of uncertainty, the principal methodologies used, any problems with these approaches, and how central the debate is to the state of scientific knowledge on global climate change. The panel published its report in 2006.[28] The report agreed that there were statistical shortcomings in the MBH analysis, but concluded that they were small in effect. The report summarizes its main findings as follows:[29] * The instrumentally measured warming of about 0.6 °C (1.1 °F) during the 20th century is also reflected in borehole temperature measurements, the retreat of gla
