Why stratospheric aerosol disproportionately cools the Indian and western Pacific Ocean
In a new study Moritz Günther, Hauke Schmidt, Claudia Timmreck, and Matthew Toohey show how aerosol perturbations in the stratosphere lead to a…
Linear climate response to idealized tropical volcanic eruptions
In a new study, Dr. Claudia Timmreck, Dr. Dirk Olonscheck and Dr. Shih-Wei Fang from the Max Planck Institute for Meteorology, together with…
How a volcanic water vapor cloud influences its own transport through the stratosphere
Dr. Ulrike Niemeier and her co-authors have successfully simulated the transport of a volcanic water vapor cloud through the stratosphere. The…
Climate feedback to stratospheric aerosol forcing: the key role of the pattern effect
In a recent study Moritz Günther, Hauke Schmidt, Claudia Timmreck (all MPI-M), and Matthew Toohey (University of Saskatchewan) argue why the cooling…

The Arctic polar vortex response to volcanic forcing of different strengths
Large volcanic eruptions can inject sulfur containing gases into the stratosphere where they build sulfate aerosols. These particles, on the one…
Risky Cooling | Dr Ulrike Niemeier
Volcanoes are sources of ideas. When they erupt, they emit large amounts of sulfur dioxide, cooling the climate.
Large explosive volcanic eruptions outside the tropics influence climate more than assumed
In a study performed within the BMBF-funded MiKlip project ALARM Dr Matthew Toohey from GEOMAR Helmholtz Centre for Ocean Research in Kiel, Dr Hauke…
