In this study, an Earth system model has been used to investigate climate feedbacks associated with increasing BVOC emissions due to higher CO₂ concentrations and temperatures. Higher BVOC emissions associated with a changed climate are found to induce an important negative climate feedback through increased aerosol formation and resulting changes in cloud properties. This feedback is found to have the potential to offset about 13 % of the radiative forcing associated with a doubling of CO₂.
