Southern Ocean cooling in a warming world

Study: Antarctica and the Southern Ocean may be experiencing a period of cooling before warming takes over, thanks to the ozone hole.

"The Southern Ocean is a very special place," says lead author Yavor Kostov. "Unlike other parts of the world’s oceans, salinity — not temperature — governs the stratification of the Southern Ocean, so layers of cold relatively fresh water float atop warmer saltier water." More...

Exploring the Impact of Global Environmental & Economic Change

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...
