Study Finds the Hidden—and Uneven—Price of Piecemeal Energy Policies

MIT researchers compare regulatory policies to a price on greenhouse gases and discover both the national and regional impacts. 

In a study published in a special edition of Energy Journal researchers examine the costs of a variety of plans to reduce carbon emissions. They find that plans that address only one sector of the economy, like the recently-proposed EPA rule on coal power plant emissions, costlier than policies that address emissions from all parts of the economy. More...

Pinpointing Climate Change Uncertainty

How severely will climate change affect the U.S.? It depends on climate policy, says a new study by MIT researchers. 

In a study published in Climatic Change, researchers examine the factors that contribute to differing predictions of regional climate change. They find that uncertain estimates of emissions are the single biggest factor. More...


MIT Announces New Initiative on Environment

Multidisciplinary program, to be led by Susan Solomon, will encourage collaborations among researchers in different fields.

This new initiative will promote research that engages wide participation by members of the MIT community to address the most significant interdisciplinary problems in our environment, spanning the physical and social sciences; engineering; and urban planning and policy. More...


National Climate Assessment: Clear and Present Danger

Henry D. Jacoby talks to Amanda Lang of the CBC's The Lang and O'Leary Exchange about the report's findings.

Climate change is happening now Jacoby says in this interview about the findings of the Third National Climate Assessment. Jacoby, the codirector emeritus of the Joint Program, is a lead author of the report's chapter on climate change mitigation. More...

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 examine the factors that contribute to differing predictions of regional climate change. They find that uncertain estimates of emissions are the biggest factor contributing to varying predictions of climate change. 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...
