Re: Climate Change is real
You should do your homework before posting studies have been disproven and de-bunkded. Check out here: http://stephenschneider.stanford.edu/Climate/Climate_Science/CliSciFrameset.html?http://stephenschneider.stanford.edu/Climate/Climate_Science/Contrarians.html and here: http://www.nytimes.com/2005/08/12/science/earth/12climate.long.html?ex=1281499200&en=2588a631b8c5cc5d&ei=5090&partner=rssuserland&emc=rss
Some scientists who question whether human-caused global warming poses a threat have long pointed to records that showed the atmosphere’s lowest layer, the troposphere, had not warmed over the last two decades and had cooled in the tropics.
Now two independent studies have found errors in the complicated calculations used to generate the old temperature records, which involved stitching together data from thousands of weather balloons lofted around the world and a series of short-lived weather satellites.
A third study shows that when the errors are taken into account, the troposphere actually got warmer. Moreover, that warming trend largely agrees with the warmer surface temperatures that have been recorded and conforms to predictions in recent computer models.
The three papers were published yesterday in the online edition of the journal Science.
The scientists who developed the original troposphere temperature records from satellite data, John R. Christy and Roy W. Spencer of the University of Alabama in Huntsville, conceded yesterday that they had made a mistake but said that their revised calculations still produced a warming rate too small to be a concern.
“Our view hasn’t changed,” Dr. Christy said. “We still have this modest warming.”
Other climate experts, however, said that the new studies were very significant, effectively resolving a puzzle that had been used by opponents of curbs on heat-trapping greenhouse gases.
“These papers should lay to rest once and for all the claims by John Christy and other global warming skeptics that a disagreement between tropospheric and surface temperature trends means that there are problems with surface temperature records or with climate models,” said Alan Robock, a meteorologist at Rutgers University.
Seminole, the same studies also show that changing climates is the norm. It happened before in the 17th century and is happening again. You do a masterful job of spin doctoring…picking and choosing the part of studies that suit your need. That is exactly what Al the Stiffy Gore does. Model used by Al Gore to predict doom and gloom has been debunked by several scientists. So please, try som other approach. I see you had nothing to say about the questions raised by those scientists.
