Arctic sea ice cover to be second-lowest recorded

Arctic sea ice cover is set to reach to the second-lowest extent since satellite observations began in 1979, according to scientists from Chinese Academy of Sciences (CAS).

To support photosynthesis, Serbian workers cut out holes in frozen lake

A team of public employees on Thursday undertook the laborious task of cutting holes in thick ice covering a lake in Serbia to help wildlife benefit from the sun's rays, as seen in images supplied by an epa photographer on site.

Melting Away: Greenland's Ice Melt Seven Percent Faster Than Predicted

A new study has revealed that ice in Greenland is melting seven-percent faster than was earlier predicted by scientists, due to the long-lasting effect of a hotspot in the Earth’s mantle under the landmass.

Earth warmer than 100,000 years ago: study

Earth is now warmer than at any time in the past 120,000 years, according to a new study Monday that provided global climate data for the past 2 million years.

Melting ice sheet may expose Cold War base, hazardous waste

United States military officials in the 1960s thought it could be thousands of years before an abandoned base in Greenland was again visible without a lot of digging, but that's only because they didn't count on the Greenland Ice Sheet melting so soon.

Greenland's ice sheet from 40,000 feet

The National Aeronautics and Space Administration (NASA) on Tuesday released a stunning image of Greenland's ice sheet taken from 40,000 feet by the Oceans Melting Greenland (OMG) field campaign team.

CO2 emissions pose huge threat to Antarctic ice sheet. Would raise the global sea level by about 60 meters

The world is on track for massive sea level rises resulting from the melting of an Antarctic ice sheet if carbon dioxide emissions continue as predicted, a leading New Zealand expert said Friday.

Threat of Sea Level Rise Intensifies as Antarctica’s Melting Ice Sheet at ‘Point of No Return’

British researchers have reinforced recent evidence that melting in the Antarctic caused by the warming of the Southern Ocean could ultimately lead to global sea levels rising by around 3 meters or nearly 10 feet.

DekoEco Geo climate news (December 2015)

 --
La Nasa vient de faire un beau cadeau aux climatosceptiques… en apparence. Une étude publiée samedi 30 octobre “contredit les conclusions notamment du Giec [Groupe d'experts intergouvernemental sur l'évolution du climat, NDLR] qui affirme que l’Antarctique perd en surface de glace”, affirme l’agence spatiale américaine.

Au contraire, la masse totale de glace aurait augmenté grâce à une accumulation continue de neige depuis 10 000 ans. Cet enneigement serait plus important que les pertes dues à la fonte des glaciers........Plus il fait chaud, plus il neige

Mass gains of Antarctic ice sheet greater than losses (NASA)

A new NASA study says that an increase in Antarctic snow accumulation that began 10,000 years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers.

Methane emission in Arctic can contribute to global warming

Scientists from the Tomsk Polytechnic University (TPU) have discovered anomalous fields where methane is emitted because of permafrost degradation on the Arctic shelf in Siberia. This can significantly change the climate on the Earth, Professor at Department of Geology and Mineral Exploration Natalya Shakova told journalists on Monday.

Arctic sea ice reaches 4th lowest extent on record

Arctic sea ice cover appears to have reached its annual minimum, measuring at 4.41 million square kilometers, the National Snow and Ice Data Center (NSIDC) said yesterday.

Scientists: Global Sea Level Rise Happening, Unavoidable

Sea levels worldwide have risen an average of nearly 3 inches (8 centimeters) since 1992, the result of warming waters and melting ice, a panel of NASA scientists said Wednesday. In 2013, a United Nations panel predicted sea levels would rise from 1 to 3 feet (0.3 to 0.9 meters) by the end of the century.

Antarctic ice study provides new insight into climate change

New Zealand scientists said Tuesday they have made a breakthrough in measuring the loss of Antarctica's ice shelves, which could better assess the effects of global climate change.

Karakoram Glaciers' Secret Revealed

Although the global warming continues to melt glaciers around the world, the ice mass in the Himalaya’s Karakoram region have been expanding, causing a fuss among the scientific community; however, the mystery has been finally revealed by a recent study published in Nature Geoscience on October 12.

“It has been a source of controversy that these glaciers have not been changing while other glaciers in the world have”, said Sarah Kapnick, a researcher at the Princeton University, as quoted by Discovery News.

Double threat for Tibet (Climate change and human development are jeopardizing the plateau’s fragile environment.)

The plateau and its surrounding mountains cover 5 million square kilo­metres and hold the largest stock of ice outside the Arctic and Antarctic; the region is thus often referred to as the Third Pole. And like the actual poles, it is increasingly feeling the effects of climate change, but rapid development is putting it doubly at risk, the report says.

Greenpeace complaint halts Norway plans to drill northermost oil well

Environmental activists from Greenpeace have blocked plans by Norwegian state-owned oil company Statoil to drill the world’s northernmost oil well, the activists' organization told ITAR-TASS on Monday. Campaigners accuse Statoil of violating the law that bans drilling in ice and near an ice boundary. Russia to apply for Arctic shelf borders in 2015 — minister Sergei Donskoy said.

The halt was called as Transocean operators' Spitsbergen rig made its way towards the site in the Norwegian sector of the Barents Sea. Work is now on hold until a Greenpeace complaint is investigated, said the protest group's press officer, Maria Favorskaya.

Could volcanoes be causing Antarctic ice loss?

AFP - Accelerating ice loss from the Antarctic ice sheet could be due in part to active volcanoes under the frozen continent's eastern part, a study said on Sunday.
From 2002 to 2011, the average annual rate of Antarctic icesheet loss increased from about 30 billion tonnes to about 147 billion tonnes, the UN's panel of climate scientists reported in September.
The icesheet is a mass of glacial land ice -- one such sheet covers most of Greenland and the other Antarctica, and together they contain most of the freshwater on Earth.
The sheets are constantly moving, slowly flowing downhill and seawards under their own weight. Portions that extend out over the water are called ice shelf.
