Near the end of “Chasing Ice,” a hunk of glacier the size of lower Manhattan explodes, rolls and crashes into the sea. If that sounds like a spoiler, well, go see the movie and you’ll know you would have known it was coming anyway. And the beauty of the movie is that it will still astound you.
Mothers, carbon, trash, vanishing ice and “secret lives”: Watch a movie for Earth Day and learn.
Otis Redding sang “you don’t miss your water ’til your well runs dry” in 1965 about pining for a lost love. Last week, Climate and Society founder and Lamont-Doherty Earth Observatory scientist Mark Cane reprised it with a much different, more literal focus: water scarcity in the 21st century.
The fourth seminar in the Earth Institute’s Sustainable Development Seminar Series, “Ch Ch Ch Changes – recent trends in temperature extremes and hydroclimate,” brought together experts in the fields of climate change and hydrology to discuss emerging trends in global weather events.
“This is a mess, and it is a mess that we have not attended to yet,” Earth Institute Director Jeffrey Sachs said at a conference on water security held today at Columbia University. “Humanity is the driver, but we don’t have our hands on the steering wheel very much.”
Sea levels are inching up year by year, and by various projections could be two to six feet higher by 2100—enough to make some small, low-lying island nations uninhabitable, or simply to wipe them off the map. What rights will citizens have to live elsewhere; in fact, will these entities actually still be nations, with [...]
Earth Institute research expeditions investigating the dynamics of the planet on all levels take place on every continent and every ocean. Most projects originate with our main research center, Lamont-Doherty Earth Observatory, and are often run in collaboration with other institutions.
Extreme weather and climate-related events already have cost the United States billions of dollars. A recent symposium focused on what we know about the causes and how changing climate affects agriculture, water supplies, wildlife and our economy.
As President Obama embarks on his second term, many Americans are hoping that the extreme weather of 2012 will mark a sea change and finally goad him into making meaningful efforts to deal with climate change.
As earth’s climate warms, scientists have tried to understand why the poles are heating up two to three times faster than the rest of the planet. Airborne dust, it turns out, may play a key role.
