Columbia engineers lead the first global analysis to characterize the responses of storm runoff extremes to climate and human-induced changes. The study sheds new light on rising magnitude of extreme flash floods.

A panel discussion and book launch event held at Columbia’s Mailman School for Public Health outline how better communication can help to bridge the research divide between climate and health.

The Global Famine was one of the worst humanitarian disasters in history, killing as many people as World War II. A new analysis suggests it could happen again, only worse because of climate change.

A special report published this week finds that things will get a lot worse if we let the planet reach 2 degrees of warming. To limit climate change to 1.5ºC of warming, the world needs to reach zero net emissions by 2050. This will be challenging, but not impossible.

A small team of scientists ventures out onto the Greenland ice sheet to study the forces large and small that are accelerating the melting of the world’s second-largest ice mass.
