We can stop global warming by midcentury if we reach global net-zero CO₂ by 2050
Every year above 1.5°C raises the risk of crossing tipping points—irreversible ice loss, shifts in ocean circulation, ecosystem collapse, increasing economic damage due to heat, flooding, more intense storms.

Getting back well below 1.5°C before 2100 is still possible, but only if we act now to peak global warming as close as possible to 1.5˚C and minimise overshoot to reduce chance of crossing tipping points and to avoid catastrophic damages.

The ethical use case for SRM is one in which governance conditions fail to enable adequately rapid decarbonization, and then there is a revolutionary change in governance that allows effective and equitable management of SRM
