United Nations-Sigma Xi Experts Address Climate Change

RESEARCH TRIANGLE PARK, NC — The world is warming, and human activity plays a significant role. While scientists typically shy away from pronouncing certainty, the vast preponderance of evidence has convinced the majority of scientists that carbon emissions from smokestacks and tailpipes are changing the climate.

Some questions do exist about how much and how fast these greenhouse gases are pushing the recent rise in temperatures. But within the scientific community there exists a broad consensus that a global response to climate change is necessary and that a wide range of options already exist to mitigate, or slow down, the warming trend and adapt to those impacts of climate change that are already underway.

So, to help develop a slate of practical policy responses, the United Nations Division for Sustainable Development and Sigma Xi have formed a Scientific Expert Group (UN-Sigma Xi SEG) to undertake a rigorous review of the existing scientific literature. The group will also discuss new and innovative ways to combat climate change.

The UN-Sigma Xi SEG kicked off that process at its inaugural meeting December 3-5, 2004 at the Sigma Xi Center in Research Triangle Park, North Carolina.

Over an 18-month period, the SEG will identify the most promising technologies

and methods the world can effectively employ,
and will make concise recommendations to the UN Commission on Sustainable Development.

The UN-Sigma Xi SEG includes experts from around the world, among them Nobel laureate Mario Molina, Sigma Xi past-president Peter Raven, and Zara Khatib of Shell International, representing a variety of scientific disciplines and backgrounds.

The UN-Sigma Xi SEG will not debate how much of climate change is attributable to human influence, and how much of it is the result of natural variability. Instead, the group will make actionable recommendations based on existing technologies and tailored to a range of social, political, economic and geographic circumstances. The UN-Sigma Xi SEG recommendations will be part of a written report delivered to representatives who sit on the UN Commission on Sustainable Development.

"The recommendations can then be deployed throughout the world to scale back various influences on climate change and to prepare for its effects," says Raven, director of the Missouri Botanical Garden. "Some degree of uncertainty will always be attached to the study of climate change, or almost any science, for that matter. But since science and economic considerations should inform the policies crafted to address climate change, decision makers must forego absolutes."

As the international honor society of science and engineering, Sigma Xi is in a unique position to bring together experts from different fields to consider practical ways of addressing global climate change. The Society's 500 chapters and more than 60,000 members also provide an effective network for disseminating information.
