The coronavirus crisis has forced Nordic universities, including Stockholm University, to run their programmes largely online. Right now there are disruptions in the videoconferencing service Zoom throughout the Nordic region due to high usage in conjunction with the start of the spring semester. The interruptions can lead to longer response times, slow connection or choppy video streams. Users may also …
Department researchers secure solid funding despite Covid Pandemic
The Department of Environmental Science received a combined 59,4 million SEK (€5,8 million) in external research funding in fiscal year 2020. The Swedish Research Council (Vetenskapsrådet) and The Swedish Research Council for Environment, Agricultural Sciences and Spatial Planning (Formas) awarded 11– and 19 million SEK (€1 million and €1,9 million), respectively, while 28 million SEK (€2,9 million) were awarded by …
Teaching at the Department of Environmental Science spring 2021
Based on current pandemic situation and responsible authorities’ recommendations, the teaching at the Department of Environmental Science will take place online during the first half of the spring semester 2021 (January – March). This means that e-meeting service Zoom is used for lectures, workshops and seminars and learning platform Athena for other course specific communication. Information about the courses that …

On the way to achieving climate neutrality
In order to manage the mammoth task of reaching climate neutrality, researchers at the Department of Environmental Science along with colleagues from other departments are collaborating within the Stockholm University Environmental Council to produce a roadmap for bringing university emissions down to zero and become climate neutral by 2040. Last year, the university made a commitment to achieving climate neutral by 2040. …

New study highlights shortcomings in current modelling of water uptake by aerosols
Atmospheric aerosols are tiny particles suspended in the air that represent one of the greatest uncertainties in our knowledge about climate change. Earth system models are the scientists’ best tool to forecast future scenarios of climate change but they require accurate information to produce reliable predictions. Now a new study by researchers at the Department of Environmental Science and colleagues …

New study unravels potential new source of mercury-containing neurotoxin in oceans
Mercury is highly toxic to humans, where exposure can lead to, for example, developmental impairment among children, loss of motor function and senses, and even death. The most common route of mercury exposure is through ingestion of fish and seafood, in the form of monomethylmercury. Now, scientists at the Department of Environmental Science have discovered a pathway that could produce …
Bacterial community composition affects persistence of chemicals in aquatic sediments
Current methods for risk assessment of persistent chemicals in aquatic sediments do not take into account the effect of bacterial communities on degradation. Now, a new study by researchers at the Department of Environmental Science and international colleagues, published in Environmental Science and Technology shows that the composition of bacterial communities present in aquatic sediments influences how long chemicals can …
Christina Rudén selected advisor to EU on chemicals
Professor Christina Rudén at the Department of Environmental Science has been selected as an observer to CARACAL, an expert group under the European Commission. Stockholm University is the only academic organisation in this important advisory group on chemicals. “To now be able to closely follow the decision-making process in the EU, we can directly contribute to the discussions with scientific knowledge and …
Swedish-Russian expedition finds new hotspots of methane emissions in Siberian Arctic seabed
Twelve researchers from the Department of Environmental Science participate in the ISSS-2020 expedition on board a Russian research vessel to study the link between biogeochemical cycles and climate change. The international research team has recently observed emissions of methane gas from new systems in the Arctic seabed. Thawing permafrost and collapsing methane hydrates in the Siberian-Arctic coast could trigger increasing emissions …
Arctic Ocean sediments reveal permafrost thawing during past climate warming
Sea floor sediments of the Arctic Ocean can help scientists understand how permafrost responds to climate warming. A multidisciplinary team from Stockholm University has found evidence of past permafrost thawing during climate warming events at the end of the last ice age. Their findings, published in Science Advances, caution about what could happen in the near future: That Arctic warming …

Iodic acid may play pivotal role in Arctic cloud formation
An international team of scientists from the Department of Environmental Science and the Bolin Centre of Climate Research at Stockholm University, the Swiss Federal Institute of Technology Lausanne (EPFL), and the Paul Scherrer Institute’s Laboratory of Atmospheric Chemistry (PSI), both in Switzerland, has identified iodic acid as a novel driver of new aerosol particle formation in the Arctic during the …
