An Arctic Ozone Hole? Not Quite

MIT researchers find that the extremes in Antarctic ozone holes have not been matched in the Arctic.

In a study published in Proceedings of the National Academy of Sciences, researchers show that ozone levels in the Arctic haven't yet sunk to the extreme lows seen in Antarctica, in part because internation efforts to limit ozone-depleting chemicals have been successful. More...

Little-Studied Man-Made Gases have Big Warming Potential

MIT researchers, part of an international team, examine the total warming impact of 25 major synthetic greenhouse gases.

In a study in Geophysical Research Letters MIT researchers estimate the warming impact of the 25 most abundant SGHGs.The authors find that, without additional limits on SGHG use, the resulting increase in warming could outweigh the climate benefits gained thus far from phasing down CFCs More...

Study: Volcanoes Contribute to Recent Warming ‘Hiatus’

Researchers find models must account for volcanic eruptions to accurately predict climate change.

In a study published in Nature Geoscience, a team of scientists from MIT and elsewhere around the U.S. report that volcanic eruptions have contributed to this recent cooling, and that most climate models have not accurately accounted for the effects of volcanic activity. More...

Predicting the Future of Global Water Stress

MIT researchers find that by 2050 more than half the world’s population will live in water-stressed areas and about a billion or more will not have sufficient water resources.

In an effort to assess future water demands and the impacts of climate change, MIT researchers have used a new modeling tool to calculate the ability of global water resources to meet water needs through 2050. More...

Confronting the Climate Challenge

Science and Policy Working Together

Understanding the complex, long-term changes in our land, air and water requires breakthroughs in measurement, modeling and prediction.

Responding to these changes requires innovative policies that comprehend agriculture, energy needs, trade and finance — along with the political and communications savvy to organize a genuinely global approach.

The Joint Program on the Science and Policy of Global Change is MIT's response to these research, analysis, and public education challenges.

At the heart of much of the Program’s work lies MIT’s Integrated Global System Model (IGSM), a linked set of computer models designed to simulate the global environmental changes that arise as a result of human causes. In this way, it explores the interplay between the Earth systems and the human systems. More...
