Antarctic sea ice grows to all-time record high

While we are seeing decline of Arctic sea ice, Antarctic sea ice hit its annual winter maximum on September 22, 2014 reaching a record area of 20.11 million square kilometers (7.76 million square miles). The National Snow and Ice Data Center (NSIDC) announced on

Study suggests current changes in the ocean around Antarctica could trigger steep rise in sea levels

A new study suggests that current conditions in the ocean around Antarctica​ could led to the rapid melting of Antarctic ice and an abrupt 3-4 meter rise in global sea level. Warming in parts of Antarctica is causing land-based ice to melt, adding massive amounts of

"We are sniffing methane" - vast methane plumes discovered escaping from the seafloor of Arctic ocean

Just a week into the methane sampling program and SWERUS-C3 Arctic expedition scientists have discovered vast methane plumes escaping from the seafloor of the Laptev continental slope. These early glimpses of what may be in store for a warming Arctic Ocean could he

Coldest June since measurements began in Adélie Land, Antarctica

Meteo-France is reporting an unusually cold month of June at their station base Dumont d'Urville located in Adélie Land (Terre Adélie), Antarctica. They recorded an average temperature of -22.4° C throughout June, which is 6.6&d

Today’s Antarctic region once as hot as California, Florida

Parts of ancient Antarctica were as warm as today's California coast, and polar regions of the southern Pacific Ocean registered 21st-century Florida heat, according to scientists using a new way to measure past temperatures.The findings, published the week of A

Volcanoes_Helped_Species_Survive_Ice_Ages

Volcanoes helped species survive ice ages

An international team of researchers has found evidence that the steam and heat from volcanoes and heated rocks allowed many species of plants and animals to survive past ice ages, helping scientists understand how species respond to climate change. The research

Increase in Arctic cyclones linked to climate change, new study shows

Winter in the Arctic is not only cold and dark, it is also storm season when hurricane-like cyclones traverse the northern waters from Iceland to Alaska. These cyclones are characterized by strong localized drops in sea level pressure, and as Arctic-wide decreases in

Giant trench discovered under Antarctic ice

UK scientists have discovered a giant trench under the ice in West Antarctica. The Ellsworth Trough trench is up to three kilometers deep and more than 300 kilometers long and up to 25 kilometers across (deeper than the Grand Canyon). The floor of this

Arctic cyclones more common than previously thought

Weather data at the Ohio Supercomputer Center reveals in a new study hundreds of smaller storms that had previously escaped detection. From 2000 to 2010, about 1 900 cyclones churned across the top of the world each year, leaving warm water and air in their

Three-year observation of West Antarctic Ice Sheet loss by CryoSat

Three years of measurements by ESA's "CryoSat" satellite show that the West Antarctic Ice Sheet is estimated to be losing over 150 cubic kilometers of ice each year which is considerably more than when last surveyed.CryoSat observes Earth with a radar alti

New volcano discovered smoldering under a thick ice of West Antarctica

During a project to reconstruct Antarctica’s climate history, scientists from Washington University in St. Louis discovered that a new volcano is smoldering under a 1.2 - 2 km thick ice. They say its heat may increase the rate of ice
