Sweden safest country in world, according to 2017 Social Progress Index

Sweden tops the list when it comes to personal safety, according to the 2017 Social Progress Index, published 20 Jun 2017. The index aims to move “beyond GDP” as a measure of a country’s success, and focuses instead on the “social and environmental elements of the performance of countries”. In the area of environmental quality, Sweden is global number two, …

Is sea spray losing its sparkle?

Atmospheric aerosols are tiny particles that scatter and absorb sunlight but also influence climate indirectly through their role in cloud formation. One of the largest sources of aerosols is sea spray which is produced over the world’s oceans. Understanding how these particles take up water from the atmosphere, their so-called hygroscopicity, is important because it determines how much sunlight they …

ACES researcher received award for excellence in aerosol science

Post-doctoral researcher Jenni Kontkanen received the Finnish Association for Aerosol Research (FAAR) Award during the 20th International Conference for Nucleation and Atmospheric Aerosols (ICNAA) in Helsinki, Finland, for her outstanding work in atmospheric nucleation research. “I am happy to receive the award, and I want to thank my Ph.D thesis supervisors Prof. Markku Kulmala and Prof. Veli-Matti Kerminen and other …

The Arctic subsea permafrost is thawing faster than previously thought

The permafrost in the ocean bottom below the East Siberian Arctic Sea is thawing at a rate of 14 cm per year. That’s a lot faster than for permafrost on land and the process may eventually lead to increased global warming through increased release of methane according to a new study published in Nature Communications by ACES researchers and international colleagues. …

We need to make the ocean visible and inspiring

“The ocean is invisible to most people, and it is easy to ignore something you never see. I think an important step in achieving SDG 14 is to continue and expand the work being done to make the ocean visible and awe inspiring to folks who normally don’t interact with it,” says Kevin Noone, Professor at the Department of Environmental Science and …

PFAS are extensively used for their water- and stain repellency.

ACES joins nationwide effort to reduce the risks of PFAS

ACES is one of the 37 government agencies and research institutions that have agreed to intensify their cooperation to tackle the problems with highly fluorinated substances (PFAS). All partners have signed a joint letter of intent to state their willingness to cooperate in reducing the risks of and increasing knowledge about PFAS. “Highly fluorinated substances are extremely difficult to break …

More microplastics in waters surrounding Stockholm than expected

Levels of microplastics in the waters near Stockholm are as high as those reported near urban areas in California, USA, shows a new study by researchers at ACES and colleagues at Stockholm University and Aquabiota Water Research, Stockholm, published in Marine Pollution Bulletin. Packaging material and boating ropes are likely sources of microplastics in these waters though other sources, such …

ACES scientist receives prestigious award for research on chemicals in textiles

ACES researcher Isabella Karlsson is one of the 14 researchers who was awarded a scholarship by the King Carl XVI Gustaf Foundation’s 50th Anniversary Fund for Science, Technology and the Environment. Isabella Karlsson received 100000SEK (€10.350) for her research project “Chemicals in Textiles – a Potential Source for Human Exposure and Environmental Pollution.” The Foundation’s aim is to promote research, technological …

Forests may store less carbon in a warmer planet

The world’s forests mitigate global warming by taking up the greenhouse gas carbon dioxide (CO2) from the atmosphere. However, a new study by ACES researchers published in Global Change Biology shows that many effects of climate change on forest mortality due to, for example, frost or droughts are still not accounted for in climate models. As a result, these models …

ACES endorses March for Science

ACES endorses March for Science on April 22, 2017 and supports its mission of standing for “robustly funded and publicly communicated science as a pillar of human freedom and prosperity”. The March for Science aims to “unite as a diverse, nonpartisan group to call for science that upholds the common good and for political leaders and policy makers to enact evidence based policies in the public interest.”  …

Stockholm University ranked in top 50 in environmental sciences

When the “QS world university rankings by subject” were announced for 2017, Stockholm University came 40th in the world in environmental sciences. Besides environmental science, Stockholm University was ranked in the top 50 universities in the world in Geography (39th), Social policy & Administration (46th), and Sociology (49th). QS Rankings are published annually by the British firm Quacquarelli Symonds (QS). …

ACES researchers in international research project to understand ocean-atmosphere interaction

On a planet that is dominated by water, determining how the oceans interact with the atmosphere is critical if we are to understand the climate of the Earth. All ocean-atmosphere exchange occurs through the sea surface microlayer that is less than 1 millimeter thick. However, many gaps remain in our understanding of the sea surface microlayer and how it impacts …
