On October 31st, representatives from across the globe will gather in Glasgow for two weeks to attend the UN climate change conference COP26. Expectations are high following last year's canceled conference, and the IPCC report released in August. As part of the Paris Agreement in 2015, it was decided that all nations would renew their climate pledges or national climate plans, so-called NDCs (Nati

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

Lack of habitats and climate change – parameters that scientists know affect the number of pollinators in the world. But exactly how big is the effect and what else contributes to the decline of bees and bumblebees? This has Maria Blasi i Romero tried to find out in her dissertation which will be presented on November 26. A sure sign of spring is the buttery yellow rapeseed fields that every year

The type of tree you plant – whether you choose native or non-native species – is of great significance for insect life in a city, more so than researchers previously thought. This is what emerges from a new study by researchers at Lund University in Sweden, who investigated the parks in the city of Malmö. Trees are crucial to insects, birds and even people in a city. They lower the temperature, p

Scientific advice to decision makers requires transparent scientific assessments, in which communication of uncertainty is important in order to avoid over- or underestimating conclusions. In her dissertation ”Robust analysis of uncertainty in scientific assessments”, doctoral student Ivette Raices Cruz, who recently defended her dissertation at Center for Climate and Environmental Science (CEC),

Increasing attention is being paid to the impact of honey bees on wild bees. In a new report from Lund University in Sweden, researchers observed that honey bees compete with wild bees for flower resources, and that more research and knowledge are needed to create the conditions for coexistence between bee-keeping and the conservation of wild bees in Sweden over the long term. In recent years, the

Scientists at Lund University have discovered for the first time that it is possible to detect insect DNA in the air. Using air from three sites in Sweden, insect DNA from 85 species could be identified. This offers scope for exploring a whole new way to monitor terrestrial biodiversity. These preliminary results was presented at Ecology Across Borders (13th-15th December) via an online poster by

On Monday, the UN’s Intergovernmental Panel on Climate Change (IPCC) published a new report on how climate change is impacting nature and people worldwide, and on the necessity for adaptation. According to the researchers, more than three billion people live in environments that are particularly vulnerable to climate change, and the same applies to many species. The researchers establish that thos

CEC is one of 24 European research institutes and organizations that is participating in the EU-funded Safeguard project, where world-leading researchers and experts are collaborating to reverse the loss of wild pollinators in Europe. The project is unique as it takes an interdisciplinary holistic approach to both the problems and the solutions. Losses of wild pollinators in Europe continue. To de

In connection with a new report on measures to mitigate climate change, researchers at Lund University in Sweden see some hopeful signs. Among other things, Lars J Nilsson, Professor of Environmental and Energy Systems at Lund University, thinks there are good prospects for achieving zero emissions by 2050 in industries such as steel, cement, and chemicals, which are currently responsible for majo

Is it possible to put a value on nature and the vital ecosystem services it provides for us? What are the pros and cons of different valuation models? These are the key questions addressed in a new report by IPBES, the UN’s biodiversity panel, to be published on 11 July. The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) can be described as the equivalent

A Vice-Chancellor’s decision has been taken on five profile areas for Lund University. One of the areas is ClimBioSis, which involves several CEC researchers. Thirty researchers from over a dozen departments at Lund University were behind the profile area application for Sustainable solutions in the climate change – biodiversity – social nexus – ClimBioSis. “The application is based on a fantastic

New data by the research infrastructure ICOS confirms that natural carbon sinks such as the ocean and forests are not stable. Climate change makes these sinks more vulnerable, in some cases even turning them into carbon emitters. This compromises current climate targets and action plans, reserachers say. Fluxes, the European Greenhouse Gas Bulletin, is a new publication by the reserach infrastruct

A new study led by Lund University in Sweden shows that cities negatively affect the diversity of birds. There are significantly fewer bird species in urban forests compared with forests in the countryside – even if the forest areas are of the same quality. The researchers examined 459 natural woodlands located in or near 32 cities in southern Sweden. They counted the occurrence of different bird

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

The machines have started rolling in at Norunda and are cutting down trees, one by one. Norunda is Sweden’s oldest measuring station for greenhouse gases and it is unique. Following several decades of being surrounded by a hundred-year-old forest, it will instead be surrounded by a clear-cut. - We expect a significant increase in greenhouse gas emissions, says professor Natascha Kljun at CEC.
