A new study shows that future ecosystem functioning will increasingly depend on water availability. Using recent simulations from climate models, an international team of scientists found several “hot spot regions” where increasing water limitation strongly affects ecosystems. These include Central Europe, the Amazon, and western Russia.
Scientists have succeeded in detecting changes in carbon dioxide emissions from fossil fuels much faster than before. Using a new method, they combined atmospheric measurements of carbon dioxide (CO2) and oxygen (O2) from the north coast of the United Kingdom. The study, with the participation of the Max Planck Institute for Biogeochemistry, was published Apr. 22 in Science Advances.
After fossil carbon dioxide emissions fell significantly on average globally in 2020, they are approaching pre-Corona pandemic levels again this year. This is the conclusion of the international Global Carbon Project. The project is now publishing its preliminary report in the journal Earth System Science Data.
The increasing amount of greenhouse gases in the atmosphere is causing our climate to warm at an alarming rate. Information is vital for societies who must decide on pathways to climate neutrality. The European ICOS research structure, including Max-Planck Institute for Biogeochemistry, provides this information, as described in a recent article.
The recent Greenhouse gas Bulletin, published by the World Meteorological Organization (WMO), highlights the importance of measuring greenhouse gases in the atmosphere to monitor emissions of such climate-threatening compounds.
For a long time, the Montreal protocol has been taken as a success story on how to implement an international agreement on environmental sustainability. It was key to protect the Earth's ozone layer. Recently, however, researchers found out that chlorofluorocarbon (CFC) emissions have been increasing again.
Director Emeritus Martin Heimann and group leader Julia Marshall of the MPI-BGC travelled to India this week, to attend the Kick-Off Workshop of our Max Planck Partner Group at the Indian Institute of Science Education and Research in Bhopal (IISER-B). The workshop provided the opportunity to bring together international key note speakers and the national community of researchers working in the field of greenhouse gas measurement and modelling
The climate conference in Bonn also sends a message to Berlin, where the parties are now negotiating the formation of a new German government - this was declared on Thursday by leading researchers who are members of the German Climate Consortium (DKK). The effects of climate change are already being felt today and Germany should start phasing out coal-fired power generation to reduce greenhouse gases, according to a joint statement published by the scientists.
The Max Planck Society supports a new Partner Group between the Max Planck Institute for Biogeochemistry (MPI-BGC), Jena, Germany, and the Indian Institute of Science Education and Research, Bhopal (IISER-B), India. The partner group‘s program aims at implementing and further developing a high-resolution inversion framework to quantify CO2 and CH4 sources and sinks that are consistent with atmospheric observations. The focus will be on the Indian subcontinent.
Within the series of "Noble talks" Prof Dr. Dr. h.c. Meinrat O. Andreae, director at MPI for Chemistry in Mainz, will talk about "Greenhouse gases and aerosoles: tug-of-war about climate".The public talk will be in German language and starts after the awarding of the Beutenberg Science Prizes at 5 p.m. in the Abbe Center Beutenberg.
For now five years the unique research aircraft HALO (High Altitude and Long Range Research Aircraft) is set to target greenhouse gases in the atmosphere. Halo operations range from the entry in the stratosphere, overflying the North and South poles up to collecting climate data in the most remote areas of the globe. During the HALO symposium on…
CO2 emissions caused by changes of land use may possibly be higher than assumed so far. This is the outcome of a study coordinated at the Karlsruhe Institute of Technology (KIT), including MPI-BGC scientist Sönke Zaehle.
