Observations show: assumption of a large trade cumulus reduction with global warming refuted

The response of trade cumulus clouds to warming is a major uncertainty in climate projections. In the last decade, a hypothesis was developed according to which the interplay of convection and cloud cover leads to increased warming.

Climate feedback to stratospheric aerosol forcing: the key role of the pattern effect

In a recent study in Journal of Climate Moritz Günther, Hauke Schmidt, Claudia Timmreck (all MPI-M), and Matthew Toohey (University of Saskatchewan) argue why the cooling following large volcanic eruptions is smaller than what one might expect from simple energy balance arguments.

The conundrum of forest expansion after the last ice age

How fast the Northern Hemisphere forest macro ecosystem tracks strongly warming climates such as projected for the near future is largely unknown. In a recent study published in Nature Communication, scientists investigated the Northern Hemisphere forest expansion after the last glacial maximum. They compared a new synthesis of pollen-based…

Earth´s orbit and greenhouse gas concentrations influence African humid periods

[Translate to englisch:]

In a new study, researchers at the Max Planck Institute for Meteorology have investigated what caused African humid periods to vary in duration and strength in the past. They found that changes in the Earth´s orbit are the most important factor and that there is a critical threshold that affects the onset of a greening Sahara. This threshold for…

One of a kind in Germany: New high-performance computer for Earth system research inaugurated

A new supercomputer named “Levante” was inaugurated at the German Climate Computing Center (DKRZ) on 22 September 2022. For the Max Planck Institute for Meteorology, it represents the essential research infrastructure for climate modeling. The supercomputer is virtually the laboratory and main tool of the researchers and thus of utmost importance…
