Satellite data confirms ‘calving’ of trillion-tonne, 5,800 sq km iceberg from the Larsen C ice shelf, dramatically altering the landscape

July 12, 2017 — A giant iceberg twice the size of Luxembourg has broken off an ice shelf on the Antarctic peninsula and is now adrift in the Weddell Sea. Continue reading Iceberg twice size of Luxembourg breaks off Antarctic ice shelf

Receding glacier causes immense Canadian river to vanish in four days

First ever observed case of ‘river piracy’ saw the Slims river disappear as intense glacier melt suddenly diverted its flow into another watercourse

April 17, 2017 — An immense river that flowed from one of Canada’s largest glaciers vanished over the course of four days last year, scientists have reported, in an unsettling illustration of how global warming dramatically changes the world’s geography. Continue reading Receding glacier causes immense Canadian river to vanish in four days

Three main dams supplying water to La Paz and El Alto are no longer fed by Andean glaciers and have nearly run dry

November 28, 2016 — The government of Bolivia, a landlocked country in the heart of South America, has been forced to declare a state of emergency as it faces its worst drought for at least 25 years.  Continue reading Shrinking glaciers cause state-of-emergency drought in Bolivia

The Smith Glacier, spilling into the Amundsen Sea, shed up to 70 meters (230 feet) per year between 2002 and 2009, according to a study

PARIS, France (Oct. 27, 2016) — A large glacier in West Antarctica lost up to half a kilometer in thickness in 7 years, thinning more quickly than scientists thought possible, according to a study released Tuesday, October 25.  Continue reading Antarctic glacier thinning more rapidly than thought – study

Sea level rise is accelerating, how much it costs is up to us

Important new research shows that sea levels are rising at unprecedented rates, and will have tremendous costs if we don’t slow them

March 14, 2016 — As humans emit heat-trapping gases into the atmosphere, it’s causing the Earth to warm. It’s also causing the ocean waters to rise. In fact, water rise is one of the clearest signatures of a warming world. The questions we want to answer are, how much will sea levels rise, and how fast?
