| Zusammenfassung |
| In recent years, several methods have been suggested for "geoengineering" the climate to
limit global temperature increase. One of these assumed geoengineering techniques tries to
reduce the incoming solar radiation through space-born reflectors at the Lagrangian
point.
With the MPI-ESM, including the GCM ECHAM6 and the ocean model MPIOM,
simulations have been performed to balance an CO2 increase by reducing the incoming solar
radiation. The simulations were preformed within the EU project IMPLICC and follow the
suggestions of the GeoMIP initiative. We are going to present results balancing a 4x CO2
increase as well as an increase of 1% CO2 per year. First results show a global decrease of
precipitation of roughly 4%, with locally stronger impacts e.g. over Eurasia and North
America as well as an impact on the surface pressure causing implications on regional
weather regimes. |
