 . This is because the climate forcing and response to SRM options are different from the forcing and response to GHG increase. Because of these differences in climate forcing and response patterns, the regional and seasonal climates of a world with a global mean warming of 1.5℃ or 2ºC achieved via SRM would be different from a world with similar global mean warming but achieved through mitigation . At the regional scale and seasonal time scale, there could be considerable residual climate change and/or overcompensating change , and there is low confidence in understanding of the climate response to SRM at the regional scale .
