0 the study and activity of finding ways to change the earth's atmosphere in order to reduce global warming (= the gradual increase in world temperatures):
Creating stratospheric sulfur aerosols deliberately is a proposed geoengineering technique which offers a possible solution to some of the problems caused by global warming.
Current biochar projects make no significant impact on the overall global carbon budget, although expansion of this technique has been advocated as a geoengineering approach.
Conservation of resources and reduction of greenhouse emissions, used in conjunction with geoengineering, are therefore considered a viable option by some commentators.
This study is intended to provide a careful, clear scientific foundation that informs ethical, legal, and political discussions surrounding geoengineering.
A new legal framework may be necessary in the event that large-scale geoengineering becomes established.
The geoengineering techniques would, in many instances, be vulnerable to being switched off or deliberately destroyed.
These processes are sometimes considered as variations of sinks or mitigation, and sometimes as geoengineering.
The active nature of geoengineering may in some cases create a clear division between winners and losers.
