Posters note: 'accidental geoengineering' is already occurring due to trop aerosols, and changes in emissions background are not being fully considered by legislators and some scientists.
http://onlinelibrary.wiley.com/doi/10.1002/grl.50459/abstract Keywords: climate extremes;aerosols;climate change;Europe;ECHAM5-HAM[1] This study investigates changes in extreme temperature and precipitation events under different future scenarios of anthropogenic aerosol emissions (i.e., SO2, black and organic carbon) simulated with the ECHAM5-HAM global climate model with focus on Europe. The simulations include a maximum feasible aerosol reduction (MFR) scenario, a CLEmod scenario where Europe implements the MFR scenario, but the rest of the world follows the current legislation scenario and a greenhouse gas scenario following SRES B2. Strongest changes relative to the year 2000 are projected for the MFR scenario in which the global aerosol reduction greatly enforces the general warming effect due to greenhouse gases and results in significant increases of temperature and precipitation extremes in Europe. Regional warming effects can also be identified from aerosol reductions under the CLEmod scenario. This becomes most obvious in the increase of the hottest summer day-time temperatures in Northern Europe. J. Sillmann L. Pozzoli E. Vignati S. Kloster J.
