Dear colleagues,
For a review paper on SRM scenario framing, we would like to study how experts think about commonly used baselines to which to compare SRM simulations.
Two frequently used baselines are as follows:
A) “Same Global Mean Surface Temperature” framing
Comparing a “moderate / high greenhouse gas with SRM” scenario to a scenario with lower greenhouse gas concentrations and no SRM, but the same GMST
B) “Same Greenhouse Gas” framing:
Comparing a “moderate / high greenhouse gas with SRM” scenario to a scenario with the same greenhouse gas concentrations and no SRM, hence higher GMST

We would like to hear from SRM researchers which of these two baselines - or others - you perceive as being dominant, and most useful.
If you would like to contribute, please fill in our short survey below. It should only take a few minutes.
