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 […]
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 […]
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 […]
By Bob Henson 20 June 2019 (Weather Underground) – The summer solstice arrives on Friday, 21 June 2019, and so does the second year of “warming stripes”. Launched in 2018, this growing campaign builds on a set of imagery developed by University of Reading climate scientist Ed Hawkins: colored stripes that portray a century-plus of global […]
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 […]
By Umair Irfan 21 May 2019 (Vox) – The weather is warming. The flowers are blooming. Noses are running. Eyes are watering. It’s allergy season, and this year it’s been severe in states like Georgia, and cities like Chicago, where the frigid winter delayed the onset. Now that it’s late May, we’re moving away from peak tree […]
By Tim Lydon 29 May 2019 (Hakai Magazine) – Alaska in March is supposed to be cold. Along the north and west coasts, the ocean should be frozen farther than the eye can see. In the state’s interior, rivers should be locked in ice so thick that they double as roads for snowmobiles and trucks. […]
By James Temple1 May 2019 (Technology Review) – Climate change is clearly making some regions wetter and others drier. But it’s been difficult for scientists to detect a clear, consistent human role in increasing the frequency and severity of global droughts given natural climate variability, regional differences, and limited data. A new report in Nature adds evidence […]
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 […]
By Hannah Hoag 11 April 2019 (Science News) – The Chugach people of southern Alaska’s Kenai Peninsula have picked berries for generations. Tart blueberries and sweet, raspberry-like salmonberries — an Alaska favorite — are baked into pies and boiled into jams. But in the summer of 2009, the bushes stayed brown and the berries never […]
