Over the next few decades, global warming-related rises in winter temperatures could significantly extend the range of the southern pine beetle, one of the world’s most aggressive tree-killing insects, through much of the northern U.S. and southern Canada.

Over the past day and a half, Hurricane Harvey’s winds have quickened from about 35 to 109 miles per hour. Columbia University researchers explain what’s driving this massive power-up.

A new study from Columbia University’s Lamont-Doherty Earth Observatory and Indiana University-Purdue University Indianapolis validates that the central core of the East Antarctic ice sheet should remain stable even if the West Antarctic ice sheet melts.

With its mission complete, the Rosetta-Ice Project, led by Columbia University polar geophysicist Robin Bell, will give scientists an unprecedented look at the Ross Ice Shelf and how it’s changing with the climate.

In this video, Lamont-Doherty Earth Observatory scientists explain their research and how it can help improve adaptation practices and make our homes, livelihoods, and the systems we rely on more resilient to extreme weather and sea level rise.
