While the ice sheets on West Antarctica and the Antarctic Peninsula are usually the ones to make the news in relation to climate change, recent studies have documented transformations that are taking place on the East Antarctic Ice Sheet as well. On the continent as a whole, large areas of ice have already melted and this trend shows no sign of slowing, meaning the implications for global sea level rise in this century could be more dramatic than earlier projections anticipated.

Anthropocene and Its Victims: Migration as Failure or Adaptive Strategy?

Gemenne argues that climate change is a form of political persecution, that victims of the anthropocene are also victims of political persecution, thus, we should reinstate the term “climate refugee.”

Because we know little about hurricane behavior during periods when Earth was warmer or colder than at present, it’s challenging to construct models to predict future trends in hurricane activity as Earth’s climate changes. To remedy this problem, researchers have been working to reconstruct records of hurricane strikes in the past.

Climate change has many asking if the days of being able to summit the world’s highest peak are numbered.

“Faux pause”

The global ocean buoy network has been expanding in recent years. Accounting for small, consistent offsets between temperatures measured by buoys and by ships reveals a greater global warming trend than previously calculated for the past 15 years. Image: Maintenance workers on an ocean buoy, NOAA.

New data support the conclusion
The “hiatus” was mostly illusion…

Two women investigating climate change from different perspectives—Christine McCarthy, a geophysicist at Lamont-Doherty Earth Observatory, and Denise Iris, a multimedia artist from Brooklyn—had a chance to spend several days together recently. In the Rock Mechanics Lab at Lamont, where McCarthy works, and a nearby “cold room” chilled to the climate of an industrial freezer, they exchanged notes on two ways of looking at ice.

Nine Columbia graduate students landed in Amman, Jordan last Friday night, after over 20 hours of travel, to begin the field study component of their course in Regional Environmental Sustainability in the Middle East. Though exhausted, they were eager to get to the hotel to meet students from Tel Aviv University – who had crossed the border earlier in the day – with whom they would be traveling through Israel and Jordan for the next 13 days.

Coming up with an international climate agreement is hard work. But the students at the Make It Work simulated negotiations in Paris managed to find a way, though they left disagreeing over just how effective the pact would be.

Hurricane Histories and Carbon Mysteries

Bahamas, hurricanes

The Bahamas might be a vacation destination for most people. But for us, they represent an excellent site to study several different questions about past, present and future climates.
