“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 […]

Alaska could see all-time temperature record today in “unbelievable” heat wave – “It’s not just the magnitude of the heat, it’s how long it will last”

By John Bacon 4 July 2019 (USA TODAY) – Alaska’s biggest city won’t be marking the nation’s 243rd birthday with fireworks displays as Anchorage struggles with dry conditions, wildfires and what could become the hottest day on record. The city’s all-time high temperature record of 85 degrees dates back 50 years. It could fall today, with a […]

Russia plans to tow a nuclear power station to the Arctic. Critics dub it a “floating Chernobyl”

By Mary Ilyushina 30 June 2019 Murmansk, Russia (CNN) – Next month, a floating nuclear power plant called the Akademik Lomonosov will be towed via the Northern Sea Route to its final destination in the Far East, after almost two decades in construction. It’s part of Russia’s ambition to bring electric power to a mineral-rich region. The 144-meter […]

Warming Arctic permafrost releasing 12 times more nitrous oxide, a potent greenhouse gas, than previously thought – “This needs to be taken more seriously than it is right now”

By Caitlin McDermott-Murphy 6 June 2019 (The Harvard Gazette) – About a quarter of the Northern Hemisphere is covered in permafrost. Now, it turns out these permanently frozen beds of soil, rock, and sediment are actually not so permanent: They’re thawing at an increasing rate. Human-induced climate change is warming these lands, melting the ice […]

A dog sled team travels through meltwater on sea ice in northwest Greenland, 13 June 2019. Steffen Malskaer got the difficult task of retrieving oceanographic moorings and weather station. Rapid melt and sea ice with low permeability and few cracks leaves the melt water on top. This photo was taken around mid afternoon local time on sea ice, in the middle of Inglefield Bredning.

By Eric Mack 18 June 2019 (CNET) – Over the past week temperatures in northern Greenland have been comparable to the weather in Seattle, causing the top layer of sea ice near the village of Qaanaaq to turn into the Arctic equivalent of a kiddie pool. Danish climate researcher Steffen Olsen took the above photo of a […]

Video: Starving polar bear wanders into Russian city of Norilsk, hundreds of miles from home

By Gianluca Mezzofiore and Nathan Hodge 19 June 2019 (CNN) – A hungry and exhausted young polar bear was spotted wandering in the suburbs of the Siberian industrial city of Norilsk this week, hundreds of miles from its usual habitat. [Over the years, Desdemona has developed a pretty think skin for doom and mass animal […]

Alaska is melting and it’s likely to accelerate global heating – “Every year there’s a new temperature record, it’s getting worse and worse and you feel like a broken record saying it”

By Oliver Milman 14 June 2019 (The Guardian) – A city in western Alaska has lost a huge stretch of riverbank to erosion that may turn it into an island, amid renewed warnings from scientists over the havoc triggered by the accelerating melting of the state’s ice and permafrost. Residents of the small city of […]

Arctic permafrost melting 70 years sooner than expected, study finds – “This change is unprecedented on this kind of time scale”

By Jan Wesner Childs 14 June 2019 (The Weather Channel) – Scientists studying climate change expected layers of permafrost in the Canadian Arctic to melt by the year 2090. Instead, it’s happening now. A new study published this week in the journal Geophysical Research Letters revealed that unusually warm summers in the Canadian High Arctic between 2003 […]

Rapid permafrost thaw unrecognized threat to landscape, global warming researcher warns – “We are watching this sleeping giant wake up right in front of our eyes”

Rapid permafrost thaw unrecognized threat to landscape, global warming researcher warns – “We are watching this sleeping giant wake up right in front of our eyes”

30 April 2019 (University of Guelph) – A “sleeping giant” hidden in permafrost soils in Canada and other northern regions worldwide will have important consequences for global warming, says a new report led by University of Guelph scientist Merritt Turetsky. Scientists have long studied how gradual permafrost thaw occurring over decades in centimetres of surface […]

Status of polar bear populations for 2014

24 January 2015 (Polar Bear Specialist Group) – The present table was discussed during late fall and early winter 2014, and agreed upon by the group on 20 January 2015. This status table will be updated whenever there is new information available that is considered credible and valid by the group. This year’s status table […]
