Newswise — A prominent climate researcher and professor at the Department of Geosciences at Texas Tech University can discuss how global climate change has impacted the environment as well as explain how differing emissions of heat-trapping gasses will shape future climate patterns for the coming century.

Katharine Hayhoe said that though global climate change is here and happening now, making immediate changes in the United States' current emissions can dramatically reduce the impacts we can expect down the road. By taking steps now to reduce emissions, the result will be much like the old adage, "an ounce of prevention is worth a pound of cure."

Most recently, Hayhoe co-led the team of more than 20 researchers which assessed the potential impacts of climate change on Chicago's people, ecosystems, water resources and economy. The study was released Thursday (Sept. 18) by Mayor Richard M. Daley.

Hayhoe served as a reviewer and contributor to the United Nations Intergovernmental Panel on Climate Change's massive international analysis of the impact of human activities on Earth's climate. The IPCC won a Nobel Peace Prize in 2007 together with former U.S. Vice President Al Gore.

Also, she has been invited by the Bush Administration to serve as a lead author on a national research assessment to evaluate climate change impacts on the United States.
