A new program to develop computational models of how marine microbes live and evolve in the global ocean has been launched to help researchers understand and simulate the relationships between climate change, marine ecosystems and the ocean carbon cycle. The collaborative effort is led by Mick Follows, and includes participants Penny Chisholm, Stephanie Dutkeiwicz, John Marshall and Chris Hill, among others. (More about the Darwin Project.)

Simulation condenses 10 years' evolution into five days of computing - Scientists at MIT have created an ocean model so realistic that the virtual forests of diverse microscopic plants they "sowed" have grown in population patterns that precisely mimic their real-world counterparts.

Dr. Denny Ellerman participated in a Hearing of the U.S. Senate Committee on Energy & Natural Resources to discuss the progress of the European Union’s Emissions Trading Scheme and to receive information on lessons learned for policymakers who want to better understand how a market-based trading program could operate efficiently and effectively in the United States.

Prof. Ronald Prinn participated in a Hearing of the U.S. House Ways and Means Committee, the first in a series on energy and tax policy, which focused on climate change. (Hearing transcript.)

Prof. Henry Jacoby participated in a Hearing of the U.S. Senate Committee on Energy and Natural Resources on the Stern Review of the Economics of Climate Change, examining the economic impacts of climate change and stabilizing greenhouse gases in the atmosphere.

Today's release of a widely anticipated international report on global warming coincides with a growing clamor within the United States to reduce greenhouse gas emissions and prevent the potentially devastating consequences of global climate change. "There's clear evidence that greenhouse gases have been increasing by very large amounts since preindustrial times, and the vast majority of these increases are due to human activity," said Prinn, whose specific task on the panel was to assess this issue.

Better models are rapidly defining the uncertainties ahead, says leading climate scientist Ronald Prinn. - The most definitive scientific assessment of global warming to date, a report released earlier this month from the Intergovernmental Panel on Climate Change (IPCC), concluded with "very high confidence" that humans are contributing significantly to global warming. The report also precisely defines the scientific uncertainties concerning the extent, impacts, and timing of global warming. Ronald Prinn, professor of atmospheric chemistry at MIT and one of the lead authors of the report, says that estimating and understanding these uncertainties is key to evaluating climate data and to deciding on a course of action. Prinn, a leading climate scientist and the director of a worldwide project that carefully monitors the amounts of dozens of greenhouse gases, recently sat down with Technology Review to explain why climate-change science is uncertain, how technology is reducing that uncertainty, and what challenges remain.
