Hi is it only fossil-fuel use it's aiming to deal with, rather than including the effects of land use change, deforestation, burping cows, etc? I wonder if geo-engineering aims to
'reduce climate change (or global warming specifically) alongside efforts to reduce ghg emissions.' This can include srm and cdr. This captures other ghg emissions sources, so for example, human release direct to air, but we are also weakening natural carbon draw down pumps in the ocean and may be causing carbon stores to release, from, for example, the oceans, forests and methane hydrates. This also captures the suggestion that geo-eng is expressly intended to be used as well as emissione reductions and not instead and not wait till emissions reductions is declared inadequate because some people are differently optimistic about that and may disagree/ be too late. Best wishes, Emily.

Word Games in the Ongoing Debates Over a Definition How about: "geoengineering schemes seek to mitigate the effect of fossil-fuel combustion on the climate in the event that fossil fuel emissions reductions prove inadequate to avoid dangerous climate change." Due to very different risks and benefits, my preference would be to have geoengineering be synonymous with SRM, and to treat CDR separately.
