When it comes to studying climate change, we generally assume that the total amount of carbon emissions determines how much the planet will warm. A new study suggests that not only the amount, but also the timing of those emissions controls the amount of surface warming that occurs on human time-scale.
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.
Removing a tonne of CO2 from the air and thus undoing a tonne of emissions? Doesn't quite work, says a study. And provides four objections in view of Earth systems.
The international Cabo Verde Atmospheric Observatory (CVAO) is being further expanded: The President of the Republic of Cabo Verde José Maria Neves and German President Frank-Walter Steinmeier laid the foundation stone on Thursday for a new laboratory building on São Vicente, one of the Cape Verde Islands off Africa. The Max Planck Institute for Biogeochemistry was involved in the construction of the station and has since been conducting long-term measurements of the greenhouse gases methane, carbon dioxide and nitrous oxide, among others, at the CVAO.
Within the framework of IAGOS, several projects for the realization of IAGOS infrastructure were carried out at the MPI-BGC under the leadership of Dr. Christoph Gerbig starting in 2005. In particular, the team developed the system for the simultaneous detection of the greenhouse gases carbon dioxide (CO2), methane (CH4), carbon monoxide (CO) and water for continuous application on airliners.
The Global Carbon Project presents its new report on global greenhouse gas budget trends. For the current year, CO2 emissions are projected to be slightly higher than before the pandemic, only slightly below the 2019 peak. If emissions remain at this high level, stabilization of the climate and achievement of the Paris climate targets is questionable.
The sources and sinks of greenhouse gases in Germany are to be better monitored in future. This is the goal of the Integrated Greenhouse Gas Monitoring System (ITMS) for Germany, which was officially launched with a three-day meeting from 18 to 20 October 2022 at the Max Planck Institute for Biogeochemistry in Jena. The ITMS is funded by the German Federal Ministry of Education and Research (BMBF) and aims to provide the German government and the public with reliable information on the state and development of greenhouse gas fluxes.
In August and September 2022, the HALO research aircraft is on mission over Canada. Also on board is Dr. habil. Christoph Gerbig, group leader at the MPI for Biogeochemistry. Together with researchers from DLR, the University of Bremen and LMU Munich, the scientists want to find out more about the natural and anthropogenic sources and sinks of methane and carbon dioxide. The CoMet 2.0 Arctic mission will also test new instruments for measuring greenhouse gases.
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). This allowed them to distinguish between natural CO2 emissions from the land surface and those from fossil fuels.
After falling significantly on average globally in 2020, fossil carbon dioxide emissions this year are approaching pre-Corona pandemic levels again. This is the conclusion of the international Global Carbon Project, published in a preliminary report.
The increasing amount of greenhouse gases in the atmosphere is leading to an alarming warming of our climate. The resulting changes are unprecedented and difficult to predict due to the complexity of the Earth system. This information is of paramount importance for decisions on pathways to climate neutrality. European ICOS research provides this information, as described in a recent article.
