There is an overlooked benefit to greatly lowering carbon emissions worldwide, says a new study co-authored by Greg Faluvegi, a researcher at the Center for Climate Systems Research at Columbia University.

A team of Columbia researchers are trekking through New York's Catskill Mountains to collect snowflake samples that could provide information on climate change and snow melt patterns.

“We can definitely see how this is going to be a catastrophe, no matter what,” said Mélody Braun, who studies risk reduction strategies at the International Research Institute for Climate and Society at Columbia University.

“We had 16 experts review it, go through it in detail, see if it meets the congressionally mandated requirements, and we agree that it did,” said Robin Bell of Columbia University’s Lamont-Doherty Earth Observatory, chair of the committee that reviewed the report.

Led by María Uriarte, an ecologist at Columbia University, researchers are studying damage caused by Hurricane Maria in Puerto Rico to better understand how an expected increase in extreme weather may undermine the ability of forests to aid the climate.

With crowdsourced genealogy, “we have the ability to connect a much more vast network of individuals and locations around the world, in a faster, cheaper way,” said Yaniv Erlich, who led the study and is a computer science professor at Columbia University.

A project led by computational geneticist Yaniv Erlich of Columbia University has created what may be the largest family tree ever: a genealogy database stretching back five centuries that links 13 million people related by blood or marriage.
