How is it possible that Global warming controversy reaches NASA climate data?”
The Little Ice Age (LIA) was a period of cooling that occurred after a warmer era known as the Medieval Warm Period. While not a true ice age, the term was introduced into scientific literature by François E. Matthes in 1939.[1] Climatologists and historians working with local records no longer expect to agree on either the start or end dates of this period, which varied according to local conditions. Some sources confine the Little Ice Age to approximately the 16th century to the mid-19th century.[2] It is generally agreed that there were three minima, beginning about 1650, about 1770, and 1850, each separated by intervals of slight warming.[3] The Intergovernmental Panel on Climate Change (IPCC) describes areas affected by the LIA: Evidence from mountain glaciers does suggest increased glaciation in a number of widely spread regions outside Europe prior to the 20th century, including Alaska, New Zealand and Patagonia. However, the timing of maximum glacial advances in these regions d
The fight over climate science is about to cross the Atlantic with a U.S. researcher poised to sue NASA, demanding the release of the same kind of information that landed a leading British center in hot water over charges that it skewed its data. Christopher C. Horner, a senior fellow at the Competitive Enterprise Institute, said NASA has refused for two years to provide information under the Freedom of Information Act that would show how the agency has shaped its climate data and explain why the agency has repeatedly had to correct its data dating as far back as the 1930s. “I assume that what is there is highly damaging,” Mr. Horner said. “These guys are quite clearly bound and determined not to reveal their internal discussions about this.” The numbers matter. Under pressure in 2007, NASA recalculated its data and found that 1934, not 1998, was the hottest year in its records for the contiguous 48 states. NASA later changed its data again, and now 1998 and 2006 are tied for the hotte
