David Hafezi Rachti was awarded twice: for his EGU poster with this year’s “Outstanding Student and PhD candidate Presentation” (OSPP) and for his Bachelor thesis, he received the 1st prize of the “Young Climate Scientist Award 2024”.
The Global Carbon Project shows that fossil CO2 emissions will continue to rise in 2024. There is no sign of the rapid and substantial decline in emissions that would be needed to limit the impact of climate change
Experts from science, journalism, local authorities and non-governmental organizations consider a change of course in communication on climate issues to be urgently needed. The appeal was published on the occasion of the K3 Congress on Climate Communication with around 400 participants in Graz.
The Chapter of the Order has elected the writer, philosopher and filmmaker Alexander Kluge and the mathematician Gerd Faltings as domestic members of the Order and the geologist Susan Trumbore and the literary scholar Stephen Greenblatt as foreign members.
Thuringia is severely affected by climate change, which is already reflected in extreme weather events and rising temperatures. The Climate Council is calling for the consistent implementation and tightening of climate policy targets in order to achieve climate neutrality by 2045. The coming legislative period is crucial for the future of Thuringia.
Nitrogen fertilizers and nitrogen oxides from fossil fuels pollute the air and drinking water, lead to the over-fertilization of water bodies and terrestrial ecosystems, reduce biodiversity and damage the ozone layer. On balance, however, they have a cooling effect on the climate.
On June 24, Prof. Dr. Henrik Hartmann, head of the Julius Kühn Institute for Forest Protection and former group leader at the Max Planck Institute for Biogeochemistry, received an important award for his scientific achievements in the field of forestry. Our warmest congratulations!
Anthropogenic emissions of nitrous oxide (N2O), a much more potent greenhouse gas per molecule than carbon dioxide or methane, increased by around 40% between 1980 and 2020. In 2020, anthropogenic emissions into the atmosphere reached more than 10 million tons per year, according to the new report "Global Nitrous Oxide Budget 2024" by the Global Carbon Project.
A recent study published in Nature, co-authored by Sönke Zaehle, suggests that eucalyptus trees do not benefit from rising CO2. Increased CO2 levels cause soil microorganisms to hold on to their phosphorus. This soil mineral, which is essential for tree growth, is therefore less available.
At the General Meeting on April 26, 2024, the new Board of Directors was elected from among the DKK members in accordance with the Articles of Association. All five candidates were elected unanimously, including Markus Reichstein. The new Board has a younger team and its range of topics has also expanded.
