SSP1-2.6 is designed to have a roughly 66% chance to limit warming to below 2C, with a central estimate of around 1.8C. So yes, it’s possible we get unlucky with climate sensitivity and end up past 2C, and that would be a situation where it would make a lot of sense to consider SRM. But saying that we know we will pass 2C in the 2030 is simply not accurate. There is a very small chance across the CMIP6 ensemble (< 5%), and it’s pretty far from the central estimate.
