“Global Warming” Computer Models Are Wrong – Again
The issue of “global warming”/”climate change” is a highly charged political debate with President Obama squarely weighing in on the side of the alarmists. He believes “climate change” is the greatest threat to U.S. national security. But, is his concern based on facts, or ideology? One new study suggests it is based on radical, left-wing ideology rather than science.
University of Alabama climatologists have released the newest version of their satellite temperature datasets. Interestingly enough, the updated satellite data came with a surprise: it lowered the Earth’s warming trend.
Version 6 of the satellite data shows faster warming in the early part of the satellite record, which stretches from Dec. 1978 to March. 2015, but shows reduced, or even eliminated, warming in the latter part of the record,wrote climatologists Roy Spencer, John Christy and William Braswell. UAH Version 6 satellite data now shows a decreased warming trend of 0.114 degrees Celsius per decade, compared to Version 5.6’s 0.140 degree trend.
This includes a decrease in the warming trend for the U.S. since the late 1970s. Spencer, Christy and Brasell noted that the U.S. “trend decreased from +0.23 to +0.17 C/decade” and the “Arctic region changed from +0.43 to +0.23 C/decade.”
“Near-zero trends exist in the region around Antarctica,” according to the UAH scientists.
So, the “sky isn’t falling” after all.
Of course not all those firmly committed to “climate change” agree with this latest revelation as the Daily Caller reveals:
The updated UAH satellite temperature data comes as scientists are looking into allegations of data tampering by government climate agencies, like NASA and NOAA. Scientists skeptical of man-made global warming argue that data adjustments made by climate agencies may not be scientifically justified.
Skeptics argue that NOAA, for example, makes adjustments that artificially cool past temperature data while warming more recent records. This creates a significantly bigger warming trend than is borne out in the raw temperature data, argue skeptics.
“While we believe that the 20th century warming is real, we are concerned by claims that the actual trend is different from – or less certain than – has been suggested,” said Kealey, who has been appointed chairman of the foundation’s investigative task force. “We hope to perform a valuable public service by getting everything out into the open.”
NOAA justifies these adjustments by saying they are necessary to correct for “biases” in the raw data. Corrections made by NOAA help make the data more accurate, they argue. NOAA’s temperature readings are based on surface thermometers from weather stations, buoys and such.
