Rift in the Larsen C Ice Shelf as seen from a NASA aircraft on Nov. 10, 2016.

The breakup of the massive Larsen C Ice Shelf in Antarctica is getting closer and will eventually produce an iceberg the size of Delaware prowling the Southern Ocean, according to new NASA data.
On Friday, NASA released an astonishing new image taken by researchers flying above the ice shelf on Nov. 10 showing the crack is getting longer, deeper and wider. Scientists think it will eventually cause a large section of the shelf to break off.

West Antarctic is melting at Triple the rate it was a decade ago

The study found they lost an average 83 gigatons per year (91.5 billion U.S. tons), or the equivalent of losing the water weight of Mount Everest (pictured) every two years

The findings of the 21-year study by Nasa and the University of California, Irvine claim to provide the most accurate estimates yet of just how fast glaciers are melting in the Amundsen Sea Embayment. 

Scientists found the rate by taking radar, laser and satellite measurements of the glaciers’ mass between 1992 and 2013.

They found they lost an average 83 gigatons per year (91.5 billion U.S. tons), or the equivalent of losing the water weight of Mount Everest every two years.

‘The mass loss of these glaciers is increasing at an amazing rate,’ said scientist Isabella Velicogna, jointly of the University of California, Irvine and Nasa’s Jet Propulsion Laboratory.

‘Previous studies had suggested that this region is starting to change very dramatically since the 1990s, and we wanted to see how all the different techniques compared,’ added lead author Tyler Utterley of UCI.

Six caribou stranded on block of ice slowly drift away from their herd after being caught out by ‘ice break-up season’

Stranded on a block of ice, these reindeer were photographed drifting away from their herd in Canada.

The six reindeer, also known as caribou, were seen floating down the Porcupine River in Old Crow, Yukon, Canada towards the border with Alaska.

The images were released by the Alaska department of homeland security and emergency management showing the ice break up season, which can cause flooding as well as catching caribou off-guard.

Dayna Lord, who took a video of the stranded animals, told CBS News: ‘We’ve seen some run off the ice and we’ve seen another bunch of caribou jump off the ice and run up the bank.

‘A lot of people feel bad, but it’s just something that happens every year.’Caribou can weigh up to 50 stone, but luckily for these animals their large hooves enable them to paddle through water, meaning they will be able return to safety when the ice block melts.

Heat flow from Earth’s mantle contributes to Greenland ice melting

The Greenland ice sheet is melting from below, caused by a high heat flow from the mantle into the lithosphere. This influence is very variable spatially and has its origin in an exceptionally thin lithosphere. Consequently, there is an increased heat flow from the mantle and a complex interplay between this geothermal heating and the Greenland ice sheet. The international research initiative IceGeoHeat led by the GFZ German Research Centre for Geosciences establishes in the current online issue of Nature Geoscience (Vol 6, August 11, 2013) that this effect cannot be neglected when modeling the ice sheet as part of a climate study.
