Stability diagram of the West Antarctic Ice Sheet (WAIS), rate R versus duration T of mass addition with unstable regime in red and stable regime in blue. Interpolation of the field is based on the conducted ensemble of stabilization experiments (gray circles). The critical threshold Rc (white curve) of stabilization is approximated by function given at the top right corner. White stars highlight simulations that share the same total amount of deposited mass (M = 8000 Gt), added at differing rate and duration, showing that the combination of both determines potential stabilization.

Adding 8 trillion tons of artificial snow to the West Antarctic Ice Sheet could stop it from collapsing – “The fundamental trade-off is whether we as humanity want to sacrifice Antarctica to save the currently inhabited coastal regions”

By Katherine J. Wu 17 July 2019 (PBS) – Gird your loins, humans: The time has come to turn part of the South Pole into our own giant snow globe. Or has it? In a study published today in the journal Science Advances, a team of German researchers suggests that dumping 8 trillion tons of artificial snow onto […]

Residents of Yakutsk, the world’s coldest city, escape 32°C heatwave by chilling on Siberian glacier

14 July 2019 (The Siberian Times) – Today it’s +32°C (89.6°F) in Yakutsk, the world’s coldest city, and locals escape heatwave like true Siberians – by chilling on ice. Today the Buluus glacier is as packed with visitors as the only official beach in Yakutsk, the world’s largest city built on permafrost. A hidden gem […]

Wildfires rage in Siberia around the “Mouth of Hell” – Scientist warns fires will accelerate growth of Batagai Depression, a giant gash in the tundra

16 July 2019 (The Siberian Times) – After a month of warm, dry weather and wildfires, the huge crater nicknamed ‘Mouth of Hell’ is now under direct threat. The fear is that flames burning on the rim of the depression will weaken the permafrost and cause a major enlargement of the Batagai or Batagaika ‘megaslump’, […]

By Brian Kahn 18 July 2019 (Gizmodo) – Vast stretches of Earth’s northern latitudes are on fire right now. Hot weather has engulfed a huge portion of the Arctic, from Alaska to Greenland to Siberia. That’s helped create conditions ripe for wildfires, including some truly massive ones burning in remote parts of the region that […]

June 2019: Earth’s hottest June on record and greatest June heat wave in European history

By Dr. Jeff Masters 18 July 2019 (Weather Underground) – June 2019 was the planet’s warmest June since record keeping began in 1880, said NOAA’s National Centers for Environmental Information (NCEI) on Tuesday. NASA also rated June 2019 as the warmest June on record, well of ahead of the previous record set in 2015. The global heat in June […]

Melting of Himalaya glaciers has doubled in recent years

By Kevin Krajick 19 June 2019 (Columbia University) – A newly comprehensive study shows that melting of Himalayan glaciers caused by rising temperatures has accelerated dramatically since the start of the 21st century. The analysis, spanning 40 years of satellite observations across India, China, Nepal and Bhutan, indicates that glaciers have been losing the equivalent of more than […]

Anchorage, Alaska roasts in 90°F heat, smashing all-time record by 5°F

By Dr. Jeff Masters 5 July 2019 (Weather Underground) – The temperature in Alaska’s largest city of Anchorage soared to an astonishing 90°F on Thursday, July 4, smashing the city’s previous all-time heat record by a remarkable 5°F. Anchorage’s average high temperature for July 4 is 65°F; records for Anchorage date back to 1952. All-time […]

Hurtigruten’s cruise ship MS Roald Amundsen is seen in the sea near Ulsteinvik, Norway, on 1 July 2019. The Roald Amundsen is the world’s first cruise ship propelled partially by battery power and is set to head out from northern Norway on its maiden voyage, cruise operator Hurtigruten said on Monday. The hybrid expedition cruise ship can take 500 passengers and is designed to sail in harsh climate waters. Named after the Norwegian explorer who navigated the Northwest Passage in 1903-1906 and was first to reach the South Pole in 1911, the ship heads for the Arctic from Tromsø this week and will sail the Northwest Passage to Alaska before heading south, reaching Antarctica in October 2019.

First hybrid electric cruise ship sails for the Arctic

By Victoria Klesty 1 July 2019 OSLO (Reuters) – The world’s first cruise ship propelled partially by battery power is set to head out from northern Norway on its maiden voyage, cruise operator Hurtigruten said on Monday. The hybrid expedition cruise ship, the Roald Amundsen, can take 500 passengers and is designed to sail in […]

“Precipitous” fall in Antarctic sea ice since 2014 revealed – “The rapid decline has caught us by surprise and changes the picture completely”

By Damian Carrington 1 July 2019 (The Guardian) – The vast expanse of sea ice around Antarctica has suffered a “precipitous” fall since 2014, satellite data shows, and fell at a faster rate than seen in the Arctic. The plunge in the average annual extent means Antarctica lost as much sea ice in four years […]

Glacier National Park’s name will outlive its glaciers – “It’s just kind of sad to see”

By Doug Struck 18 June 2019 GLACIER NATIONAL PARK, MONTANA (The Christian Science Monitor) – Maria Clemens took time off from her post-college summer job on a Montana ranch to hike into this national park to see a glacier. “I don’t like it,” she pronounced on the trail as she returned. “It’s just kind of […]
