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 […]

2010-2019: Earth’s hottest decade on record marked by extreme storms, deadly wildfires – “The climate of the 20th Century is gone. We’re in a new neighborhood.”

By Bob Berwyn 19 December 2019 (InsideClimate News) – Deadly heat waves, wildfires and widespread flooding punctuated a decade of climate extremes that, by many scientific accounts, show global warming kicking into overdrive. As the year drew to a close, scientists were confidently saying 2019 was Earth’s second-warmest recorded year on record, capping the warmest […]

Scientists update status of polar bear populations with 2019 data

By Dag Vongraven 20 September 2019 (PBSG) – At the last meeting of the IUCN/SSC Polar Bear Specialist Group (PBSG) in Anchorage in 2016, the group agreed that there was a need for new and documented criteria for the assessment of status and trends of polar bear populations. Work to develop a new set of […]

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 […]
