Study: Cutting Emissions Pays for Itself

Savings from healthier air can make up for some or all of the cost of carbon reduction policies. 

In a study published in Nature Climate Change MIT researchers find that savings on health care spending and other costs related to illness from better air quality can be big—in some cases more than 10 times the cost of policy implementation.  More...


Why a Global-Warming Pact Won't Stop Global Warming

How should success at high-stakes international talks be measured?

The National Journal covers an MIT study that finds that the 2015 UN climate talks in Paris are unlikely to limit global temperature increase to frequently stated goals.  More...


THOMSON REUTERS FOUNDATION: Curbing air pollution could help crops thrive

Controlling air pollution could help curb projected declines in global food supplies, says a new MIT study, suggesting policymakers should consider both climate change and ozone pollution in efforts to ensure the world has enough food. More...

Regulations Only a First Step in Cutting Emissions

MIT study finds that sectoral regulations will not cut emissions enough to substantially limit climate change, but are a good first step toward phasing in a price on carbon. 

In a study published in a special edition of Climate Policy researchers examine the costs and effects of single-source regulations, and find that regulations will reduce emissions, but not enough to substantially slow future climate change—and at a steep cost compared to price-based policies.  More...


Study: Climate change and air pollution will combine to curb food supplies

Ozone and higher temperatures can combine to reduce crop yields, but effects will vary by region.

Many studies have shown the potential for global climate change to cut food supplies. But these studies have, for the most part, ignored the interactions between increasing temperature and air pollution — specifically ozone pollution, which is known to damage crops. 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...
