How the Arctic Ocean became saline
Jun 07, 2017 (SPX)
Every year, ca. 3,300 cubic kilometres of fresh water flows into the Arctic Ocean. This is equivalent to ten percent of the total volume of water that all the w...
Domes of frozen methane may be warning signs for new blow-outs
Jun 07, 2017 (SPX)
These domes are the present-day analogue to what scientists think preceded the craters found in the near-by area, which were recently reported in Science. The c...
Antarctic ice rift close to calving, after growing 17km in 6 days - latest data from ice shelf
Jun 05, 2017 (SPX)
The rift in Larsen C is likely to lead to one of the largest icebergs ever recorded. It is being monitored by researchers from the UK's Project Midas, led by Sw...
Massive craters formed by methane blow-outs from the Arctic sea floor
Jun 05, 2017 (SPX)
"The crater area was covered by a thick ice sheet during the last ice age, much as West Antarctica is today. As climate warmed, and the ice sheet collapsed, eno...
Geoscientific evidence for subglacial lakes
Jun 05, 2017 (SPX)
Hundreds of subglacial lakes currently exist beneath the Antarctic Ice Sheet, with Lake Vostok being the largest and best known. The challenges involved in expl...

NASA Discovers a New Mode of Ice Loss in Greenland
May 26, 2017 (JPL)
This long pulse of mass loss, called a solitary wave, is a new discovery that may increase the potential for sustained ice loss in Greenland as the climate cont...
Methane seeping from Arctic seabed may have an upside
May 26, 2017 (UPI)
For nearly a decade now, scientists have debated the idea. Most agree that the volume of frozen methane, known as methane hydrate, trapped beneath the Arctic Oc...

May 25, 2017 (SPX)
A NASA-led effort to advance our ability to monitor changing Arctic and boreal ecosystems has started its second season, with the first aircraft taking flight o...
Elevation could help explain why Antarctica is warming slower than Arctic
May 23, 2017 (SPX)
Climate models and past-climate studies show that, as the Earth warms in response to an increase in greenhouse gases in the atmosphere, temperatures rise faster...
Antarctica 'greening' due to climate change
May 22, 2017 (SPX)
Few plants live on the continent, but scientists studying moss have found a sharp increase in biological activity in the last 50 years. A team including scienti...
