Updated basic facts about climate change that are undisputed in the scientific community.

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.

A new study reveals that surprisingly small increases in atmospheric CO₂ lead to detectable effects on ecosystem functioning. Using simulations of the land surface model developed at the Max Planck Institute for Biogeochemistry, an international team of scientists finds that enhanced CO₂ first affects entities of the carbon cycle such as vegetation productivity and the extension of leaf area.
