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 David Wallace-Wells 6 September 2023 (The New York Times) – Canadian wildfires have this year burned a land area larger than 104 of the world’s 195 countries. The carbon dioxide released by them so far is estimated to be nearly 1.5 billion tons — more than twice as much as Canada releases through transportation, […]
By Liny Lamberink 28 August 2023 (CBC News) – Wildfires in the N.W.T have emitted 97 megatonnes of carbon into the air so far this year — 277 times more than what was caused by humans in the territory back in 2021. Mark Parrington, a senior scientist working at the European Union’s Copernicus Atmosphere Monitoring Service (CAMS), […]
By Kathy Gunn, Matthew England, and Steve Rintoul 25 May 2023 (The Conversation) – Antarctica sets the stage for the world’s greatest waterfall. The action takes place beneath the surface of the ocean. Here, trillions of tonnes of cold, dense, oxygen-rich water cascade off the continental shelf and sink to great depths. This Antarctic “bottom […]
18 March 2022 (Max Planck Institute for Chemistry) – Rapid warming in the Arctic and accelerated glacier and sea ice melting have a huge impact on the global environment. Greenhouse gases, such as carbon dioxide, and black carbon aerosols are well-known warming agents. In contrast, atmospheric, light absorbing brown carbon particles belong to the least […]
By Adam Voiland 23 July 2021 (NASA) – While plumes of wildfire smoke from western North America have passed over the northeastern U.S. and Canada multiple times each summer in recent years, they often go unnoticed. That is because smoke that spreads far from its source typically moves at a fairly high altitude—between 5 and 10 kilometers—as […]
By Bernard Looney 17 June 2020 (BP) – The COVID-19 pandemic may well turn out to be the most tragic and disruptive event that many of us will ever live through. As I write this – in the middle of June – over 400 thousand people globally have lost their lives to the infection. Millions […]
By Jennifer Chu 8 July 2019 (MIT News) – In the brain, when neurons fire off electrical signals to their neighbors, this happens through an “all-or-none” response. The signal only happens once conditions in the cell breach a certain threshold. Now an MIT researcher has observed a similar phenomenon in a completely different system: Earth’s […]
By Blaine Friedlander 14 August 2019 (Cornell Chronicle) – As methane concentrations increase in the Earth’s atmosphere, chemical fingerprints point to a probable source: shale oil and gas, according to new Cornell research published 14 August 2019 in Biogeosciences, a journal of the European Geosciences Union. The research suggests that this methane has less carbon-13 relative […]
By Kasha Patel 1 August 2019 (NASA) – In June and July 2019, more than 100 long-lived and intense wildfires blazed within the Arctic Circle. Most of them burned in Alaska and Siberia, though a few raged even in Greenland. As these fires lofted thick plumes of smoke into the skies, they also launched megatons of tiny, harmful particles into the […]
