Das internationale Cabo-Verde-Atmosphären-Observatorium (CVAO) wird weiter ausgebaut: Der Präsident der Republik Cabo Verde José Maria Neves und Bundespräsident Frank-Walter Steinmeier legten am Donnerstag den Grundstein für ein neues Laborgebäude auf São Vicente, einer der Kapverdischen Inseln vor Afrika. Das Max-Planck-Institut für Biogeochemie war am Aufbau der Station beteiligt und führt seitdem am CVAO Langzeitmessungen u.a. der Treibhausgase Methan, Kohlendioxid und Lachgas durch.
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.
Mathias Göckede und Martin Heimann erhalten gemeinsam mit Kooperationspartner ein prestigereiches ERC Synergy Grant für klimarelevante Permafrost-Forschung.

The who’s who of highly cited scientific authors includes for 2018 five scientists from MPI-BGC at different career levels. Altogether, with 76 highly cited scientists the whole Max Planck Society ranks on 5th place among worldwide research institutions.
Im Who's Who der weltweit hoch-zitierten Forscher sind 2018 gleich fünf Wissenschaftler unseres Max-Planck-Instituts für Biogeochemie (MPI-BGC) auf verschiedenen Karrierestufen vertreten. Insgesamt rangiert die Max-Planck-Gesellschaft mit 76 hoch-zitierten Forschern auf Rang 5 der Liste weltweiter Forschungsorganisationen.
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.
Lange Zeit wurde das Montrealer Protokoll als Erfolgsbeispiel genannt, wie ein internationales Umweltabkommen umzusetzen ist. Es war der Meilenstein zum Schutz der Ozonschicht. Jedoch entdeckten vor Kurzem Forschende, dass die FCKW-Emissionen wieder zugenommen haben. Dieser Fall zeigt, wie wichtig unabhängiges Monitoring ist – auch für…
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.
Emeritus Direktor Prof. Dr. Martin Heimann und Gruppenleiterin Dr. Julia Marshall vom MPI-BGC reisten diese Woche nach Indien, um am Kick-Off Workshop der Max-Planck-Partnergruppe am Indian Institute of Science Education and Research in Bhopal (IISER-B) teilzunehmen. Der Workshop brachte internationale Experten sowie Indiens nationale Wissenschaftler auf dem Gebiet der Messung und Modellierung von Treibhausgasen zusammen.
