A new report from the United Nations finds that the warming effect of greenhouse gases on the planet has increased 43 percent just since 1990. Columbia University’s Radley Horton discusses the problem and potential solutions.

Kate Marvel, a Columbia climate scientist, is committed to spreading the word about climate science. Her TED Talk on the subject drew more than a million viewers.

To predict how much climate change will raise sea level, researchers like Lamont-Doherty Earth Observatory's Stan Jacobs are studying ice shelves, where vast expanses of ice meet the ocean.

“I think what we’re going to have to figure out is how we can adapt to the conditions we are stuck with in terms of increases in fire,” says Winslow Hansen, a climate scientist at Columbia's Lamont-Doherty Earth Observatory.

Park Williams, a climate scientist at Columbia's Lamont-Doherty Earth Observatory, explains the complex drivers of California's big autumn wildfires.

“When I look at any of these events and see the headlines, it’s almost always a situation where [the disaster] is caused by natural variability … and the climate change part of it is making it worse,” said Lisa Goddard, director of the International Research Institute for Climate
