1.4 Other aspects of climate change

Temperature is far from being the only aspect of the Earth system to consider. In Session 6, you saw GeoMIP predictions of decreases in rainfall: the models predicted the tropics would be drier all year round, and that northern high latitudes would be slightly drier in the summer.

This introduces potential ethical issues and difficulties for Solar Radiation Management. Different regions would see different climate changes, and those might be worse than preindustrial or current climate, or even future climate change without geoengineering. These changes would vary around the world, so making fair decisions would be extremely difficult.

The varying effectiveness of SRM for different regions and aspects of the Earth system poses a serious ethical challenge.
