Within the activities of the EU HORIZON 2020 project SCIPPER, recordings of NOx (nitrogen oxides) emissions from vessels were remotely collected and analysed. The data originated from different measurement locations in the Baltic Sea and North Sea within 2022. The analysis shows that 50 per cent of the emission measurements of ships that had to comply with the latest Tier III NOx levels, far excee

Not all air pollution are created by humans. As the global average temperature rises, harmful emissions from plants increase and more desert dust is dispersed in the atmosphere. Researchers from the University of Gothenburg ande MERGE-members, among others, warn that this leads to increased health risks. Climate change does not only mean that the global average temperature is rising by several deg

Dense urban areas amplify the effects of higher temperatures, due to the phenomenon of heat islands in cities. Large investments in the electricity network will be necessary to cool us down during heatwaves and keep us warm during cold snaps, according to a new study by researchers from the University of Gothenburg and Lund University. The study presents a modelling platform that ties together cli

As the ice-breaker Odin set sail on the 7th of May, MERGE-researchers Luisa Ickes, Lovisa Nilsson and Nicolas Faure were on it! The purpose of the expedition is to get to the Arctic Ocean at the beginning of the melting season. The researchers within ARTofMELT (Atmospheric rivers and the onset of sea ice melt) want to find out, among other things, when the ice starts to melt and what processes are

Professor Torben R. Christensen has a comment published in the international top science journal Nature. In the comment, he looks back at the scientific work in the field of methane flux research since more than 20 years, and worries about the fact that Arctic methane emissions remain almost as uncertain as they were then, and points out that the research on methane fluxes needs to be extended."Me

The vegetation in Europe has not always looked like it does today. Just as the ice sheet retreated in northern Europe and the population increased, man began to affect the landscape to a greater extent by deforestation. At first on a small scale to facilitate hunting, for example, and then more systematically to make way for agriculture. A new study shows that one of the consequences was changes i

Ice sheets, snow and the ocean as far as the eye can see. No shipping vessels or people in sight, and only polar bears for company. The icebreaker Oden sails between Svalbard and Greenland, and this spring, doctoral student Lovisa Nilsson, and a member of MERGE, joined the ship to study the transition from winter to summer in the Arctic, and how soot affects the melting of sea ice. For six weeks,

In September 13-15, 2023 the ClimBEco summer meeting entitled “Double up and double down: linking the global climate and biodiversity crises to bring about fast, fair and transformative change” was held. My research background is not in marine sciences, nor am I used to living by the sea, yet something about the Kristineberg Center for Marine Research brings about a comfortable feeling of being in

All particles that reach the atmosphere cause different chemical reactions. Particles come partly from natural sources such as volcanic eruptions and forest fires, and partly from pollution and emissions. Aerosol researcher Johan Friberg studies particles at high altitudes. He fears that the global increase in forest fires could have a significant impact on the ozone layer. “I study the air in the

After a year of intensive work by many involved, the Swedish Climate Symposium with its close to 400 participants, has come to an end. Now an evaluation of the conference awaits, but the feeling is that most people experienced it as a successful event. To take the pulse during the symposium itself, we did a couple of short interviews with some of those who were there. Satisfied organisers Josefin

Have you noticed that when scientists are asked whether or not a particular extreme weather event is due to climate change, they usually respond with something like "It fits the pattern, but we can't say for sure that this particular event is worse because of climate change"? Weather attribution is a new phenomenon that is changing this. Climate scientist Wilhelm May at Lund University helps us ge
