Lamont-Doherty Earth Observatory marine biologists Craig Aumack and Andy Juhl spend a month each spring in Barrow studying the algae dwelling in and under the sea ice. Their goal is to learn more about the different species of algae that compose these communities and their role in the Arctic marine food web.
“One of the ways that climate change is going to manifest is through warmer temperatures. … What we are seeing, in line with our projections, is that even if you assume constant precipitation, the temperature effects are so large that it is going to dry things out. This is going to have really big impacts on soil moisture, reservoirs and stream flow for irrigation and drinking water. The availability of water is going to decline into the future, and the challenge is adjusting for that, and what that means for agriculture and development.”
As environmentalists have pushed for greater investment in wind and solar energy, critics have insisted that renewable sources of power could never provide more than a fraction of world energy demand. Evidence is mounting, however, that the critics are wrong.
The impact of climate change on New York City could be even more severe than previously thought, putting more people at risk from increasingly frequent floods and heat waves, according to a report by the New York City Panel on Climate Change that was released Monday.
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 [...]
