GLIN==> Visiting Scientist to Discuss Why "Global Warming Is Unequivocal"



Scientists have completed a thorough examination of the Earth’s vital signs and concluded that the planet “is running a fever,” says one of the nation’s leading climate researchers and a lead author of the latest report from the Intergovernmental Panel on Climate Change (IPCC).


And the situation is apt to get much worse, says Kevin E. Trenberth, head of the Climate Analysis Section at the National Center for Atmospheric Research in Boulder, Colo.


Trenberth will present a free public lecture at 7 p.m. Monday, April 23, in UW-Madison’s Morgridge Auditorium, Room 1100, Grainger Hall, 975 University Avenue, Madison, Wis. Limited metered parking is available below Grainger Hall in Lot 7 (Brooks Street), with additional public parking available in the State Street Campus Ramp.


Trenberth is one of 140 authors who worked on the first volume of the IPCC’s latest assessment report. Entitled “Climate Change 2007: The Physical Science Basis,” it is considered the “gold standard” on the state of scientific knowledge of climate change, and it affirms that “warming of the climate system is unequivocal” and it is “very likely” (90 percent certainty) due to human activities. Trenberth will discuss the evidence for these conclusions and what they mean for the future.


Trenberth’s lecture is the keynote presentation in the 2007 seminar series “Climate Change in the Great Lakes Region: Starting a Public Discussion,” sponsored by the UW Sea Grant Institute and the Wisconsin Coastal Management Program. Over the next several months, experts will speak at sites throughout Wisconsin about what is known about the effects of climate change on our region, what is predicted and what can be done to adapt.
