Wind, warm water revved up melting Antarctic glaciers

By Carol Rasmussen 19 September 2017(Jet Propulsion Laboratory) – A NASA study has located the Antarctic glaciers that accelerated the fastest between 2008 and 2014 and finds that the most likely cause of their speedup is an observed influx of warm water into the bay where they’re located.The water was only 1 to 2 degrees […]

Giant iceberg that broke free from Antarctica has begun drifting

By Erik Ortiz 27 September 2017 (NBC News) – After breaking free from Antarctica this summer, a giant iceberg roughly the size of Delaware is moving on to open waters. New satellite images from TerraSAR-X show the iceberg known as A68 has begun to drift away from the Larsen C ice shelf and is being […]

Methane from tundra, ocean floor didn’t spike during previous natural warming period – “A greater percentage of the methane in the atmosphere today is due to human activities, including oil drilling, and the extraction and transport of natural gas”

By Mark Floyd 23 August 2017CORVALLIS, Oregon (OSU) – Scientists concerned that global warming may release huge stores of methane from reservoirs beneath Arctic tundra and deposits of marine hydrates – a theory known as the “clathrate gun” hypothesis – have turned to geologic history to search for evidence of significant methane release during past […]

Global sea level rise accelerates since 1990 – Greenland ice largely responsible for the accelerating pace of sea-level rise

By Alister Doyle 26 June 2017 OSLO (Reuters) – The rise in global sea levels has accelerated since the 1990s amid rising temperatures, with a thaw of Greenland’s ice sheet pouring ever more water into the oceans, scientists said on Monday.The annual rate of sea level rise increased to 3.3 millimeters (0.13 inch) in 2014 […]

Larsen C responds to the calving of Iceberg A68

By Adrian Luckman and Martin O’Leary 19 July 2017 (Project MIDAS) – On July 12 2017, data from the Sentinel-1 satellite confirmed the calving from the Larsen C Ice Shelf of Iceberg A68, a slab of ice 5,800 km in area and weighing more than 1 trillion tonnes. New Sentinel-1 interferometry data from July 18 […]

Arks of the Apocalypse: All around the world, scientists are building repositories of everything from seeds to corals to mammal milk

By Malia Wollan 18 July 2017 (The New York Times) — It was a freakishly warm evening last October when a maintenance worker first discovered the water — torrents of it, rushing into the entrance tunnel of the Svalbard Global Seed Vault, a storage facility dug some 400 feet into the side of a mountain […]

Antarctica’s Larsen C Ice Shelf calves trillion ton iceberg

By Martin O’Leary and Adrian Luckman 12 July 2017 (Project MIDAS) – A one trillion tonne iceberg – one of the biggest ever recorded – has calved away from the Larsen C Ice Shelf in Antarctica. The calving occurred sometime between Monday 10th July and Wednesday 12th July 2017, when a 5,800 square km section […]

Larsen C rift comes within 5 km of calving – Iceberg will have an area of 5,800 square kilometers

By Adrian Luckman and Martin O’Leary 7 July 2017 (Project MIDAS) – As the Larsen C ice shelf moves closer to calving one of the largest icebergs on record, there are clear signs of changes in the part of the shelf which is about to calve. In late June 2017, the soon-to-be iceberg tripled in […]

Larsen C iceberg accelerates ahead of calving

By Martin O’Leary and Adrian Luckman 28 June 2017(Project MIDAS) – In another sign that the iceberg calving is imminent, the soon-to-be-iceberg part of Larsen C Ice Shelf has tripled in speed to more than ten meters per day between 24th and 27th June 2017. The iceberg remains attached to the ice shelf, but its […]

Widespread snowmelt detected in West Antarctica during unusually warm summer – “We can expect more major surface melt events”

By Pam Frost Gorder 15 June 2017 COLUMBUS, Ohio (OSU) – An area of West Antarctica more than twice the size of California partially melted in 2016 when warm winds forced by an especially strong El Niño blew over the continent, an international group of researchers has determined.In the June 15 issue of the journal […]
