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. more

The new report by the Global Carbon Project shows: Fossil CO₂ emissions will reach a record high in 2023.
If emissions remain this high, the carbon budget that remains before reaching the 1.5°C limit will probably be used up in seven years. Although emissions from land use are decreasing slightly, they are still too high to be compensated by renewable forests and reforestation. more

In the annual ranking of the world's most cited and thus most influential scientists, five authors from our institute are once again represented in 2023. more

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. more

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. more
