Climate Model Mistake Highlights Uncertainty Surrounding Climate Science
Human affect on global warming far from sure thing
DALLAS (April 27, 2006) - The BBC announced last week that a "glitch" in its climate model caused it to show past and present temperatures as higher than those actually recorded and to forecast future temperatures higher than reasonably predicted. The error, termed "fatal" by researchers, demonstrates that climate science continues to evolve and the exact impact of humans on global warming is not fully known, according to an expert with the National Center for Policy Analysis (NCPA).
"Evidence continues to mount that scientists skeptical of the claim that human activities are causing potentially catastrophic climate change are right," said NCPA Senior Fellow H. Sterling Burnett. "The models used by environmental alarmists to stoke climate change fears have repeatedly been shown to be unreliable."
Likewise, a new study released by Duke climatologist Gabriele Hegerl indicates that the climate is less sensitive to greenhouse gases than many predict - with there only being a 5 percent chance that the average worldwide temperature change would exceed 11 degrees Fahrenheit if CO2 levels doubled.
Burnett notes that in spite of the flaws in climate models and new studies refuting alarmists' claims, the media and environmentalists fail to acknowledge this evidence.
Last month a group of scientists sent a letter to Canadian Prime Minister Stephen Harper asking him to reexamine climate data and reconsider the Kyoto Protocol. The media barely covered the event. However, news of another letter to the prime minister by a different group of scientists urging immediate action to prevent further global warming got immediate attention in the blogosphere and mainstream media.
"Hegerl's study and the revelation of the flaw in the BBC's climate model demonstrate that the jury is still out on the cause and future impact of climate change," said Burnett. "Alarmists cherry pick the data that they highlight to promote their agenda."
