25 September 2024 (IBS Center for Climate Physics) – A study, published in the journal Nature Communications by an international team of climate scientists and permafrost experts shows that, according to new climate computer model simulations, global warming will accelerate permafrost thawing and as a result lead to an abrupt intensification of wildfires in the Subarctic and […]
By Rick Bowmer and Mark Thiessen 28 September 2024 MERTARVIK, Alaska (AP) – Growing up along the banks of the Ninglick River in western Alaska, Ashley Tom would look out of her window after strong storms from the Bering Sea hit her village and notice something unsettling: the riverbank was creeping ever closer. It was […]
By Sara-Lena Brännström 17 April 2024 (Umeå University) – A team of over 70 scientists from different countries used so called open-top chambers (OTCs) to experimentally simulate the effects of warming on 28 tundra sites around the world. OTCs basically serve as mini-greenhouses, blocking wind and trapping heat to create local warming. The warming experiments […]
By Alec Luhn 24 December 2023 (Scientific American) – It was a cloudy July afternoon in Alaska’s Kobuk Valley National Park, part of the biggest stretch of protected wilderness in the U.S. We were 95 kilometers (60 miles) from the nearest village and 400 kilometers from the road system. Nature doesn’t get any more unspoiled. […]
By Kat Kerlin 8 November 2022 (UC Davis) – From Sierra Nevada forests to Arctic peatlands, climate warming is turning some long-held carbon sinks into carbon sources as wildfires increasingly send stored carbon up in smoke. In the Arctic, vast amounts of carbon have been locked beneath frozen soil, much of it in peatlands. Climate warming dries […]
8 September 2022 (Stockholm Resilience Centre) – Multiple climate tipping points could be triggered if global temperature rises beyond 1.5°C above pre-industrial levels, according to a major new analysis published in the journal Science. Even at current levels of global heating the world is already at risk of passing five dangerous climate tipping points, and risks […]
25 May 2022 (AWI) – Due to global warming, temperatures in the Arctic are climbing rapidly. As a result, the treeline for Siberian larch forests is steadily advancing to the north, gradually supplanting the broad expanses of tundra which are home to a unique mix of flora and fauna. Experts from the Alfred Wegener Institute […]
By Jake Spring 28 April 2022 SAO PAULO, April 28 (Reuters) – The world lost an area of forest the size of the U.S. state of Wyoming last year, as wildfires in Russia set all-time records and Brazilian deforestation of the Amazon remains high, a global forest monitoring project report said on Thursday. Global Forest Watch, which […]
14 December 2021 (BBC News) – The highest temperature ever recorded in the Arctic, 38C (100F), has been officially confirmed, sounding “alarm bells” over Earth’s changing climate. The World Meteorological Organization (WMO) on Tuesday verified the record, reported in the Siberian town of Verkhoyansk on 20 June last year. The temperature was 18C higher than […]
By T. A. Moon, M. L. Druckenmiller, and R. L. Thoman 6 December 2021 (NOAA) – As the influences of human-caused global warming continue to intensify, with the Arctic warming significantly faster than the globe overall, the 2021 Arctic Report Card (ARC2021) brings a broad view of the state of the Arctic climate and environment.
