Rising CO2 has unforeseen strong impact on Arctic plant productivity

In a new study, a team of researchers around Alexander Winkler and Prof Victor Brovkin from the department “The Land in the Earth system” at the Max Planck Institute for Meteorology (MPI-M) show that most Earth system models (ESM) underestimate the response of Arctic plant productivity to rising atmospheric carbon dioxide (CO2) concentration. These...

MiKlip publishes the decadal climate forecasts for 2019–2028 including the annual forecast for 2019

The MiKlip project, led by Prof Jochem Marotzke and coordinated by Dr Sebastian Hettrich at the Max Planck Institute for Meteorology, has made its decadal climate forecasts for 2019–2028 available online.

Decadal climate predictions cover time-scales of several years up to a decade. They close the gap between short-term weather predictions,...

China and India dominate in greening the Earth

A team of researchers led by Prof Ranga Myneni of Boston University, USA, a winner of the prestigious Humboldt Research Award and a long-term guest at the Max Planck Institute for Meteorology (MPI-M), show in a new study that there is now about five and half million square kilometers of extra green leaf area yearly compared to the early 2000s. This...

Quantifying the Irreducible Uncertainty in Near-Term Climate Projections

Recently, Prof Jochem Marotzke, managing director at the Max Planck Institute for Meteorology (MPI-M) and head of the department “The Ocean in the Earth System” published in a recent paper in WIREs that even if CO2 emissions fall after 2020, there is a one-in-three chance that global surface warming will speed up until 2035 instead of slowing down,...
