WHAT IS GEOENGINEERING?

WHAT IS GEOENGINEERING?

Geoengineering also referred to as climate engineering, is deliberate and large-scale intervention of Earth’s climate system in order to mitigate climate warming. Two kinds of techniques are involved in geoengineering, Carbon Dioxide Removal (CDR) and Solar Radiation Management (SRM). CDR is removing greenhouse gases out of atmosphere and SRM attempts to offset greenhouse effect by reducing solar energy absorption. Emission control is always the first option to mitigate climate warming, and geoengineering could serve as a backup plan.

WHY WE STUDY GEOENGINEERING, ESPECIALLY SRM? HOW WE DO IT?

WHY WE STUDY GEOENGINEERING, ESPECIALLY SRM? HOW WE DO IT?

In light of the difficulties in achieving emission control, serious consequences of "business as usual" (Fig. 2) and urgency of approaching climatic ‘tipping point’, SRM seems to be the only feasible option mitigating global warming in a short time (Fig. 3), but the uncertainty of basic mechanism and potential impacts of SRM are so huge, that we absolutely can’t do any experiment on our real planet, instead we use computer modeling as our only way to improve our understanding of geoengineering.
