Arctic sea-ice loss didn't happen by chance
The ongoing rapid retreat of Arctic sea ice is often interpreted as the canary in the mine for anthropogenic climate change. In a new study, scientists have now systematically examined the validity of this claim. They find that...
A search for large-scale effects of ship emissions on clouds and radiation in satellite data
This publication was chosen as research highlight by Nature Climate Change Aerosols released by ships can locally induce brighter or even new clouds, but it has been unclear whether this phenomenon extends far beyond the...
Multi-year prediction of the Atlantic Meridional Overturning Circulation at 26.5 °N possible
Climate scientists around Dr. Daniela Matei and Prof. Dr. Jochem Marotzke from the Max Planck Institute for Meteorology (MPI-M) and Prof. Dr. Johanna Baehr from Hamburg University's Cluster of Excellence "CliSAP" have...
A winning formula for climate change conferences?
The likelihood of damage caused by climate change in the medium term could bring poor and rich countries to effectively reduce carbon dioxide emissions A global agreement on effective climate change mitigation could be...
Reforestation’s Cooling Influence - A Result of Farmer’s Past Choices
This publication was chosen as AGU journal highlight Decisions by farmers to plant on productive land with little snow enhances the potential for reforestation to counteract global warming, concludes new research from...
Southern Ocean phytoplankton increases cloud albedo and reduces precipitation

Still hope for Arctic sea ice
The substantial decline of Arctic sea ice in recent years has triggered some fears that the ice cover might be approaching a “tipping point” beyond which the loss of the remaining sea ice would become unstoppable. However, new...
Aerosol size confines climate response to volcanic super-eruptions

“Turbulent Mixing Processes in the Earth System”: New Max Planck Research Group at MPI-M
On 1 August 2010 a new Max Planck Research Group began its work at the Max Planck Institute for Meteorology (MPI-M): Dr. Juan Pedro Mellado was one of eight researchers, and the only in the earth sciences, selected by the Max...
Which future emission pathway is required to limit the global warming to no more than 2°C above pre-industrial levels?
This question is investigated by Erich Roeckner and co-authors at the Max Planck Institute for Meteorology (MPI-M) in a study entitled ”Historical and future anthropogenic emission pathways derived from coupled climate-carbon...
