Neue Daten von ICOS bestätigen, dass natürliche Kohlenstoffsenken wie die Ozeane und Wälder nicht stabil sind. Der Klimawandel macht diese Senken anfälliger und verwandelt sie in einigen Fällen sogar in Kohlenstoffemittenten. Dies gefährdet die…
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.
At the Amazon Tall Tower Observatory (ATTO), the research station of a joint German-Brazilian project in the Brazilian rainforest, scientists have been studying the ecosystems of the Amazon and their interactions with the atmosphere and climate for more than 10 years. Recently, representatives of the Brazilian Ministry of Research and foreign ambassadors visited the station.
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.
Die zunehmende Menge an Treibhausgasen in der Atmosphäre führt zu einer alarmierenden Erwärmung unseres Klimas. Informationen für Entscheidungen über Wege zur Klimaneutralität sind von höchster Bedeutung. Die europäische ICOS-Forschung, darunter das Max-Planck-Institut für Biogeochemie, liefert diese Informationen, wie in einem kürzlich erschienenen Artikel beschrieben.
Within the framework of the German-Brazilian joint project ATTO (Amazon Tall Tower Observatory) with its research station in the Brazilian rainforest, scientists for several years have gained valuable data and insights for climate and environmental research. For German partners, the Max Planck Society will continue to ensure the operation of the station and the research. In addition, the German Federal Ministry of Education and Research (BMBF) will fund the project for another three years with around 5 million euros through ATTO+.
Die in einer Sonderausgabe von Philosophical Transactions B veröffentlichten Ergebnisse verdeutlichen, dass im Dürre-Sommer 2018 die Fähigkeit der Vegetation, CO2 aus der Atmosphäre zu binden (Kohlenstoff-Senke), um 18 Prozent zurückgegangen ist. Gleichzeitig wurden die niedrigsten Ernteerträge seit Jahrzehnten erreicht.
In einem allgemein verständlichen Bericht erläutern ICOS-Wissenschaftler die messbaren Effekte der Corona-Krise auf den CO2-Gehalt der Atmosphäre. Sie stellen in Aussicht, wie die Bemühungen, weitere Infektionswellen sowie einen ökonomischen Kollaps zu verhindern, nicht nur die Infektionskurve sondern idealerweise auch die CO2-Emissionskurve abflachen könnte.
