Extreme Niederschläge sollten bei wärmeren Temperaturen stärker werden. Messdaten aus den Tropen zeigen, dass die abkühlende Wirkung von Wolken diesen Zusammenhang verschleiert. Korrigiert man die Wolkeneffekte, wird klar dass steigende Temperaturen extreme Niederschläge verstärken.
Die Temperaturen an der Landoberfläche werden hauptsächlich durch die Erwärmung durch Sonnenlicht, aber auch durch Verdunstung und konvektive Wärmeübertragung in der Vertikalen bestimmt. In einer neuen Studie wurde die Rolle dieser beiden Prozesse mit Hilfe einer physikalischen Leistungsgrenze bestimmt.
Windturbinen brauchen beim massiven Ausbau Platz, um möglichst effizient zu sein. Generell kann Fotovoltaik deutlich mehr Strom erzeugen als Windkraft.
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.
Microorganisms in aquifers deep below the earth’s surface produce similar amounts of biomass as those in some marine waters. This is the finding of researchers led by the Friedrich Schiller University Jena and the German Centre for Integrative Biodiversity Research (iDiv). The study has been published in Nature Geoscience.
You can't see them with the naked eye, but our forest ground is littered with microorganisms. They decompose falling leaves, thereby improving soil quality and counteracting climate change. But how do these single-celled organisms coordinate their tasks? An international research team has been looking into this little-understood process. The results of the study were recently published in Scientific Reports.
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.
International researchers found a pattern of extreme climate conditions leading to forest dieback. To do this, the team had collected worldwide records of climate-related tree and forest dieback events over the past nearly five decades. The results, recently published in Nature Communications, reveal an ominous scenario for forests in the context of ongoing global warming.
International forest experts analyzed major tree and forest dieback events that occurred globally in the last decades in response to climate extremes. To their surprise many forests were strongly affected that were not considered threatened based on current scientific understanding. The study, led by the MPI-BGC and published in Annual Reviews in Plant Biology, underscores also that further tree and forest dieback is likely to occur.
An international research team succeeded in identifying global factors that explain the diversity of form and function in plants. Led by the University of Zurich, the Max Planck Institute for Biogeochemistry in Jena and the University of Leipzig, the researchers collected and analyzed plant data from around the world.
Precisely how does a forest system and the individual plants within it react to extreme drought? Understanding the processes involved is crucial to making forests more resilient in the increasingly dry climate that will result from climate change, and also important for refining climate models. A research team led by Prof. Dr. Christiane Werner from the University of Freiburg has conducted the most extensive experiment to date into this subject using stable isotopes to trace flows of water and carbon through a forest.
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.
