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 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 […]
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 Svetlana Skarbo 1 August 2019 (The Siberian Times) – Predators seek food in villages all around Siberia as climate expert warns of worse fires each year due to soaring rise in temperatures, 10°C above average. Wild animals are turning to humans as they escape gas-chamber-like woods, with wildfires continuing to rage across almost 3 […]
1 August 2019 (WMO) – According to the new data from the World Meteorological Organization and Copernicus Climate Change Programme, July 2019 at least equalled, if not surpassed, the hottest month in recorded history. This follows the warmest ever June on record. The data from the Copernicus Climate Change Programme, run by the European Centre […]
30 July 2019 (AFP) – Gigantic forest fires have regularly raged through the vast expanses of Russia’s Siberia, but the magnitude of this year’s blazes has reached an exceptional level with fears of a long-term impact on the environment. As fires sweep across millions of hectares enveloping entire cities in black smoke and noxious fumes, […]
29 July 2019 (The Siberian Times) – A series of natural disasters are hitting Siberia, with the latest a dire threat from severe flooding to Baikal – the oldest and deepest lake in the worth, containing 20% of the planet’s unfrozen freshwater. The alert concerns flooding in Baikalsk – where evacuation has begun – and […]
By Edward Helmore 26 July 2019 (The Guardian) – The Arctic is suffering its worst wildfire season on record, with huge blazes in Greenland, Siberia, and Alaska producing plumes of smoke that can be seen from space. The Arctic region has recorded its hottest June ever. Since the start of that month, more than 100 wildfires have […]
16 July 2019 (The Siberian Times) – After a month of warm, dry weather and wildfires, the huge crater nicknamed ‘Mouth of Hell’ is now under direct threat. The fear is that flames burning on the rim of the depression will weaken the permafrost and cause a major enlargement of the Batagai or Batagaika ‘megaslump’, […]
![Effects of experimental open-top chamber (OTC) warming on ecosystem respiration (ER). Experimental warming increased ER across the tundra biome but the magnitude of the response varied across time and space. Effect of OTC warming on ER Hedges’ SMD calculated as (mean ER of the warmed plots − mean ER of the control plots)/pooled standard deviation across the 136 growing season datasets (that is, unique experiment × ER measurement year combinations). On the top of the graph, a blue diamond shows the mean estimate (est. = 0.57 and 95% CI [0.44–0.70], error bars) of the ER response across the 136 datasets, as well as the Q value testing for heterogeneity and P value from the meta-analysis. Black dots represent ER Hedges’ SMDs of individual datasets and 95% CIs (black error bars) in alphabetical and chronological order. Individual datasets are represented by the experiment ID in black (left) and ER measurement year (right) in a colour scale ranging from dark blue, light blue, orange to red which represents increasingly longer warming duration at the time of ER measurements. Experiments with more than 1 year of ER data are grouped. See Supplementary Tables 1, 2 and 4 for details on the datasets and SMD and CI values. The black dashed vertical line (SMD = 0) represents no change in ER with warming whereas the areas to the right and left of it represent increased (SMD > 0) versus decreased (SMD](https://desdemonadespair.net/wp-content/uploads/2024/04/image-47.png)
