The Sun Shines Alone: The True Cause of Global Warming?
By Noah Shachtman June 03, 2008 | 1:46:00 PMCategories: Science!
The Army is weighing in on the global warming debate, claiming that climate change is not entirely man-made. Instead, Dr. Bruce West, with the Army Research Office, argues that "changes in the earth’s average surface temperature are directly linked to ... the short-term statistical fluctuations in the Sun’s irradiance and the longer-term solar cycles."
In an advisory to bloggers entitled "Global Warming: Fact of Fiction [sic]," an Army public affairs official promoted a conference call with West about "the causes of global warming, and how it may not be caused by the common indicates [sic] some scientists and the media are indicating."
In the March, 2008 issue of Physics Today, West, the chief scientist of the Army Research Office's mathematical and information science directorate, wrote that "the Sun’s turbulent dynamics" are linked with the Earth's complex ecosystem. These connections are what is heating up the planet. "The Sun could account for as much as 69 percent of the increase in Earth’s average temperature," West noted.
It's a position that puts West at odds with nearly every major scientific organization on the planet. "The American Meteorological Society, the American Geophysical Union, and the American Association for the Advancement of Science all have issued statements in recent years concluding that the evidence for human modification of climate is compelling," Science magazine observes. So has the United Nations' Intergovernmental Panel on Climate Change (IPCC), which shared the 2007 Nobel Peace Prize with Al Gore, for their work on global warming. [UPDATE: West himself said during a Thursday conference call that global warming is at least partially man-made -- and maybe as much as "70 percent" due to human intervention.]
West faults the IPCC and other scientific groups have "conclude[d] that the contribution of solar variability to global warming is negligible." He argues that these groups have done a poor job modeling the Sun's impact, however, and that's why they have "significantly over-estimated" the "anthropogenic contribution to global warming."
In recent days, the science and politics of climate change have once again taken center stage. NASA's Inspector General just issued a report, acknowledging that political appointees "reduced, marginalized or mischaracterized climate change science made available to the general public." Yesterday, the Senate began debating a bill that would cap carbon dioxide emissions -- considered one of the leading causes of man-made global warming.

It does seem that the sun's heat is getting hotter and more intense...I wonder if the army's nailed this one right on the head?
