Hunger, drought, disease: UN climate report reveals dire health threats – “The basis for our health is sustained by three pillars: the food we eat, access to water, and shelter. These pillars are totally vulnerable and about to collapse.”

By Patrick Galey 23 June 2021 (AFP) – Hunger, drought and disease will afflict tens of millions more people within decades, according to a draft UN assessment that lays bare the dire human health consequences of a warming planet. After a pandemic year that saw the world turned on its head, a forthcoming report by […]

Map showing the age of sea ice in the Arctic at winter maximum in 2000 (left, week of March 18) and 2020 (right, week of March 21). Ice older than 5 years (white) is very rare today; only a small ribbon remains along the islands of the Canadian Arctic. Age is a stand-in for ice thickness and durability; young ice is thinner and more likely to melt in the summer. NOAA Climate.gov map, based on data from the National Snow and Ice Data Center.

Sea ice loss and extreme wildfires mark another year of Arctic change – “The transformation of the Arctic to a warmer, less frozen, and biologically changed region is well underway”

8 December 2020 (NOAA) – NOAA’s 15th Arctic Report Card catalogs for 2020 the numerous ways that climate change continues to disrupt the polar region, with second-highest air temperatures and second-lowest summer sea ice driving a cascade of impacts, including the loss of snow and extraordinary wildfires in northern Russia. The Arctic Report Card is […]

Hottest Arctic temperature record probably set with 100-degree reading in Siberia

By Andrew Freedman 21 June 2020 (The Washington Post) – A northeastern Siberian town is likely to have set a record for the highest temperature documented in the Arctic Circle, with a reading of 100.4 degrees (38 Celsius) recorded Saturday in Verkhoyansk, north of the Arctic Circle and about 3,000 miles east of Moscow. Records […]

May 2020 was hottest May on record – “The really large anomalies started during January, and since then this signal has been quite persistent”

By Kelly Macnamara and Marlowe Hood 5 June 2020 PARIS (AFP) – Temperatures soared 10 degrees Celsius above average last month in Siberia, home to much of Earth’s permafrost, as the world experienced its warmest May on record, the European Union’s climate monitoring network said Friday. Large swathes of Siberia have been unusually warm for […]

The boreal winter season 19/20 was by far the warmest winter season ever recorded in Europe – “Europe has been experiencing its mildest winter on record”

4 March 2020 (C3S) – With persistent mild weather over Europe, particularly in the north and east, the past winter was 3.4 °C warmer than the average winter for the period 1981-2010. The temperature was almost 1.4°C higher than that of the previous warmest winter, 2015/16. Back in November C3S seasonal predictions provided strong indications […]

“Fast and dramatic” permafrost thaw will double previous estimates of potential carbon emissions – “Forests can become lakes in the course of a month”

By Natacha Larnaud 4 February 2020 (CBS News) – Rapidly thawing permafrost in the Arctic has scientists worried. According to a new study published Monday in the journal Nature Geoscience, the ice that holds the soil together is melting, causing hillsides to collapse and massive sinkholes to open up as a result. And that dramatic disruption to […]

Arctic shifts to a carbon source due to winter soil emissions – “The warmer it gets, the more carbon will be released into the atmosphere from the permafrost region, which will add to further warming”

By Samson Reiny 8 November 2019 (NASA) – A NASA-funded study suggests winter carbon emissions in the Arctic may be adding more carbon into the atmosphere each year than is taken up by Arctic vegetation, marking a stark reversal for a region that has captured and stored carbon for tens of thousands of years. The […]

Flowers grow in new meadows in Western Siberia above the 70th parallel, only 1000 miles away from the North Pole. An expedition organised by Tomsk State University in the summer of 2019 found oases of rich vegetation formed in places of actively thawing permafrost. Russian scientists were surprised to find carpets of herbs and flowers, with daisies, dandelions, polar poppies, horsetail, several types of wormwood, cereals, and even willow growing in Arctic “oases”.

Poppies, dandelions, and daisies bloom in never-before-seen Arctic oases

By Olga Gertcyk 16 October 2019 (The Siberian Times) – ‘Blooming’ might be the last word to associate with the Arctic, yet pictures below show meadows bursting with life as brightly-coloured flowers blossom in lush green grass. And while vegetation in khasyreis, basins of drained Arctic lakes, is less of a surprise, researchers discovered ‘bursts […]

Radical warming in Siberia leaves millions on unstable ground – “The permafrost is thawing so fast, we scientists can’t keep up anymore”

By Anton Troianovski and Chris Mooney 3 October 2019 ON THE ZYRYANKA RIVER, Russia (The Washington Post) – Andrey Danilov eased his motorboat onto the gravel riverbank, where the bones of a woolly mammoth lay scattered on the beach. A putrid odor filled the air — the stench of ancient plants and animals decomposing after […]

Russian scientists find giant methane fountains in Arctic Ocean – “This is the most powerful seep I have ever been able to observe”

By Alec Luhn 8 October 2019 MOSCOW (The Telegraph) – Russian scientists in the Arctic Ocean said they have discovered the most powerful methane gas fountain ever recorded, highlighting the danger of this greenhouse gas accelerating climate change or causing an oil or gas spill as it erupts from thawing permafrost. A research expedition from […]
