Roy W. Spencer, PhD Biography

Title:
Principal Research Scientist at the Earth System Science Center at the University of Alabama in Huntsville
Position:
Con to the question "Is Human Activity Primarily Responsible for Global Climate Change?"
Reasoning:

“[W]e are finding satellite evidence that the climate system is much less sensitive to greenhouse gas emissions than the U.N.’s Intergovernmental Panel on Climate Change (IPCC, 2007) climate models suggest that it is. And if that is true, then mankind’s CO2 emissions are not strong enough to have caused the global warming we’ve seen over the last 100 years…

[M]ost of the warming could be the result of a natural cycle in cloud cover forced by a well-known mode of natural climate variability: the Pacific Decadal Oscillation (PDO). While the PDO is primarily a geographic rearrangement in atmospheric and oceanic circulation patterns in the North Pacific, it is well known that such regional changes can also influence weather patterns over much larger areas…

[R]ecent satellite measurements – even though they span only 7.5 years – support the Pacific Decadal Oscillation as a potential major player in global warming and climate change.”
