Boreal peatlands store large amounts of carbon, but warmer and drier conditions caused by climate change may turn these ecosystems into carbon sources. Equipped with drones and thermal cameras Julia Kelly, who recently received her doctorate at the Centre for Environmental and Climate Science (CEC), has studied what factors affect the CO2 fluxes in peatland ecosystems. Boreal forests and peatlands

Two Lund University climate scientists, Kimberly Nicholas, who has acted as an observer at two global climate summits, and Markku Rummukainen, Sweden’s IPCC representative, talk about what comes next following the recent IPCC report. What do you view as the next steps following what was concluded in the IPCC report? Kimberly: Something the report makes absolutely clear is that to stop warming, hum

Climate change and biodiversity losses have long been addressed in parallel organisations. Now the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) and the UN Intergovernmental Panel on Climate Change (IPCC) are launching the first global report that integrates the two issues. This is a welcome and much needed move, according to three researchers at the Univ

At this ClimBEco summer meeting, mostly held online but with parallel in-person workshops in Gothenburg, Lund and Malmö, was themed around one of humanities ultimate equalizers; that of food. The way we produce, move and use food globally has important implications on just about every challenge we currently face in the world, reflected in the overall title of the summer meeting. To start off the e

Primitive stoves and diesel engines produce soot particles, besides being bad for your health, have a negative effect on the climate. By affecting the atmosphere’s ability to form cloud droplets and ice particles, soot can dislodge the radiation balance. This according to doctoral student John Falk, who is currently working on his dissertation about cloud droplet and ice particle formation in clou

Earlier this week, The Royal Swedish Academy of Sciences awarded the Nobel Prize in Physics 2021 to Syukuro Manabe, Princeton University, USA, and Klaus Hasselmann Max Planck Institute for Meteorology, Hamburg, Germany, “for the physical modelling of Earth’s climate, quantifying variability and reliably predicting global warming”. Birgitta Svenningsson and Deliang Chen are happy about the choice o

The Polar regions play a crucial role in balancing global climate – with the poles heating up much faster than the rest of the world. Yet, climate projections for the Polar regions still have significant uncertainties. This is hampering efforts to curb climate change and deal with the effects we already see at play not only within the Polar regions, but also in Europe and the rest of the world. Po

Dear all, We are proud to welcome you to the first national scientific climate conference in Sweden - a unique opportunity for climate scientists to interact, reflect, and identify knowledge gaps and opportunities for the future. The Swedish Climate Symposium will highlight the main conclusions of the 6th Assessment Report (AR6) of the IPCC and its consequences for Sweden. In a series of topical p

In February, ClimBEco PhD students gathered for our annual winter meeting. For the second consecutive year – but hopefully for the last time – the meeting was held digitally due to pandemic restrictions, with a small lunch gathering at the conclusion. During this two-day event, participants presented their PhD research to each other in an interdisciplinary setting. They had the option of sharing e

Where, how often, and how much it is going to rain or snow in the future is difficult to predict. Anders Ahlström studies the importance of precipitation for ecosystems on Earth – and contributes with new knowledge in a complex and fraught area. Across the world, researchers are in agreement on future warming patterns. However, future precipitation is more difficult to predict, and climate models

Thomas Pugh, principal investigator at BECC and researcher at MERGE, is one of the researchers behind a new study that is published in Science. In the study, the researchers compared results from three major modeling approaches that provide information on different aspects of risk on the impact of climate change on forests in the 21st century. Forests harbor enormous biodiversity and are a major c

China has suffered an extreme heat wave this summer and the Yangtze River has been completely dried up in parts. This is the topic of a new episode of the Swedish podcast Kinapodden with MERGE-researcher Deliang Chen as one of the guests. China has suffered an extreme heat wave this summer. The Yangtze River has been completely dried up in parts, resulting in an acute energy shortage. In a new epi

Effects of a warmer Arctic are not only negative for the climate, according to a new thesis from the Centre for Environmental and Climate Science at Lund University, Sweden. Modelling showed that moving the tree line upwards could increase carbon storage, as trees sequester more carbon in their biomass than tundra plants. But the results are uncertain. The Arctic – the area north of the Arctic Cir

After this summer meeting, one cannot understate the importance of and unmistakeable delight in meeting in-person after a long, pandemic-sized hiatus. On the shores of the Baltic Sea, in the crisp early autumn of Skåne, a group of 28 ClimBEco PhD students spent two nights and two days getting to know one another and learning about the topic of sustainable coastal environments. Hosted by the Simris

The UN’s annual climate change conference takes place this year in Sharm el-Sheikh in Egypt. Over the course of two weeks, representatives of the world’s nations will gather to discuss how to achieve the goals of the 2015 Paris Agreement and contribute to the climate transition. At this year’s COP, the focus will be on topics such as climate finance, loss and damage, adaptation to climate change a

Swedish, previously uncut forests have been converted to plantations at a steady rate since 2003. In a new study, MERGE-researcher Anders Ahlström and his research team find that old forests have been cut and lost by ∼1.4% per year since 2003, and at this rate they will disappear by the 2070s. Natural ecosystems that have experienced limited direct human impact are threatened by land use change. O

MERGE is one of the partners in CLIMB-FOREST - a new Horizon Europe project that will investigate how the climate is affected by different ways of managing the forest. There is a lot of expertise in each individual country, but there is no coordinated overview of Europe’s forests and forest health. A major new EU project, CLIMB-FOREST, will create an overview of European forests and forestry over

Tipping elements are regions that are vulnerable to climate change and capable of sudden drastic changes. However, it is not well understood to what degree tipping of one element in the system can influence other tipping elements. In this study, the researchers establish long-distance connections (teleconnections) between tipping elements using network analysis – thus applying a new approach in cl
