Holocene vegetation transitions and their climatic drivers in MPI-ESM1.2

Do we understand the migration of global vegetation patterns over the last millennia during the transition from the mid Holocene some 8000 years ago to present-day climate? Can we even predict what to expect in paleo-botanical records based on what we know? To tackle these questions Anne Dallmeyer, Martin Claussen (both MPI-M), Ulrike Herzschuh…

Atmospheric data treasure for the trade wind region collected, processed, and made available

Thirteen scientists from Germany, France and the United States collaborated to collect measurements and process them into a dataset that provides a rich characterization of the thermodynamic and kinematic aspects of the atmosphere in the North Atlantic trades. The effort was led by Dr. Geet George, a post-doctoral scientist at the Max Planck…

Predicting global warming: how water vapor affects the radiative forcing of CO2

In a new study in Geophysical Research Letters, Dr. Lukas Kluft, Dr. Sally Dacie, Prof. Dr. Bjorn Stevens (scientists at the Max Planck Institute for Meteorology) and Dr. Manfred Brath and Prof. Dr. Stefan A. Buehler (both scientists at Universität Hamburg) show that the use of a widely used radiative transfer scheme leads to incorrect predictions…

Global Carbon Project: Tracking the fate of man-made CO2

After the global average of fossil carbon dioxide emissions dropped significantly in 2020, this year they are again approaching levels before the COVID-19 pandemic. This is the finding of the Global Carbon Project (GCP). Every year, scientists take stock of how much CO2 has been anthropogenically emitted around the world and is absorbed again by…

Humidity differences and their effect on the clear-sky radiation budget in global storm-resolving models

In a new study in the Journal of Advances in Modeling Earth Systems Theresa Lang, Dr. Ann Kristin Naumann, Prof. Bjorn Stevens and Prof. Stefan A. Bühler show that the model disagreement in the distribution of tropical humidity is reduced in the next generation of global climate models.

Tracking the fate of anthropogenic carbon in the ocean — Modeling the global 13C-Suess effect

Rising fossil-fuel CO2 emissions deplete the atmospheric concentrations of the heavy carbon isotope 13C. This phenomenon, called the 13C Suess effect, can be used to discern the pathways of anthropogenic carbon in the Earth system. In a new study, Dr. Bo Liu, Dr. Katharina D. Six, and Dr. Tatiana Ilyina investigated the sources of uncertainty in an…
