Melting at one of the largest ice caps on Earth has produced a big jump in its flow speed, satellite imagery suggests.
Austfonna on Norway's Svalbard archipelago covers just over 8,000 sq km and had been relatively stable for many years. But the latest space data reveals a marked acceleration of the ice in its main outlet glacier to the Barents Sea.
The research was presented in Brussels on Thursday to mark the launch of the EU's new Sentinel-1a radar spacecraft.

New report: Climate change has 'moved firmly into the present' and nation needs to adapt
Saying that climate change has “moved firmly into the present,” a federal scientific panel Tuesday released a report cataloging the impacts of such changes, saying some would actually be beneficial “but many more are detrimental.”
The American Southeast and Caribbean regional is “exceptionally vulnerable” to rising sea levels, extreme heat events, hurricane and decreased water resources, the report said. Seven major ports in the region are vulnerable. And residents can expect a significant increase in the number of hot days – defined as 95 degrees or above – as well as decreases in freezing events.
Oklahoma earthquakes tied to oil, gas work
The U.S. and Oklahoma Geological Surveys said an increase in earthquakes in the state may be attributed to heightened oil and gas activity.
USGS said it examined the rate of increase in earthquakes in Oklahoma and found they weren't due to random fluctuations in seismic activity in that state.
The joint study found injecting wastewater underground can lead to pressure increases that may contribute to earthquakes.
"Much of this wastewater is a byproduct of oil and gas production and is routinely disposed of by injection into wells specifically designed and approved for this purpose," USGS said.
Antarctic Ice Shelf On Brink Of Unstoppable Melt That Could Raise Sea Levels For 10,000 Years
Part of East Antarctica is more vulnerable than expected to a thaw that could trigger an unstoppable slide of ice into the ocean and raise world sea levels for thousands of years, a study showed on Sunday.
The Wilkes Basin in East Antarctica, stretching more than 1,000 km (600 miles) inland, has enough ice to raise sea levels by 3 to 4 metres (10-13 feet) if it were to melt as an effect of global warming, the report said.
The Wilkes is vulnerable because it is held in place by a small rim of ice, resting on bedrock below sea level by the coast of the frozen continent. That "ice plug" might melt away in coming centuries if ocean waters warm up.
U.S. Youths sue U.S. government over climate inaction
Young people across the country are suing several government agencies for failing to develop a climate change recovery plan, conduct that amounts to a violation of their constitutional rights, says their lawyer Julia Olson.
Their futures are at stake, say the young plaintiffs.
“Climate change is the biggest issue of our time,” said 13-year-old Xiuhtezcatl Roske-Martinez, a member of nonprofit Kids vs. Global Warming, a plaintiff in the suit.
“It’s not every day you see young people getting involved politically but the climate crisis is changing all that. Every generation from here on out is going to be affected by climate change,” added Roske-Martinez, who also founded environmental nonprofit Earth Matters and organized successful actions in his hometown of Boulder, Colo.
Lynchburg, Va., oil train derailment illustrates threat to rivers
As Pat Calvert steers a small motorboat over the James River, it’s impossible to not notice the smell of motor oil, and it’s not coming from the boat.
Two days after a CSX train derailed and put three tank cars full of crude oil into the river, Calvert, who keeps tabs on the Upper James River for the James River Association, is only beginning to survey the spill’s impact. Wednesday’s derailment spared the town from catastrophe, but not the river.
Geophysicists link fracking boom to increase in earthquakes
The swarm of earthquakes went on for months in North Central Texas, rattling homes, with reports of broken water pipes and cracked walls and locals blaming the shudders on the fracking boom that’s led to skyrocketing oil and gas production around the nation.
Darlia Hobbs, who lives on Eagle Mountain Lake, about a dozen miles from Fort Worth, said that more than 30 quakes had hit from November to January.
“We have had way too many earthquakes out here because of the fracking and disposal wells,” she said in an interview.
Greenpeace activists block Russian tanker, arrested
Dutch police arrested 44 Greenpeace activists attempting to stop a Russian oil tanker from unloading its cargo of arctic oil in Rotterdam.
Armed anti-terrorist police boarded the Greenpeace ship Rainbow Warrior and made the arrests. Although the ship was towed ashore and those arrested were taken to several Rotterdam police stations, the activists were quickly released. Several were members of the “Arctic 30” who were arrested in Russia in 2013 and jailed for over two months on piracy charges.
Megacities contend with sinking land
Subsiding land is a bigger immediate problem for the world's coastal cities than sea level rise, say scientists. In some parts of the globe, the ground is going down 10 times faster than the water is rising, with the causes very often being driven by human activity.
Decades of ground water extraction saw Tokyo descend two metres before the practice was stopped.
Speaking at the European Geosciences Union General Assembly, researchers said other cities must following suit.
