A clear eyed view of what we need to do next.
One thing 2025 made clear: Durable progress on climate in the US will require structural reform to our corrupted political systems. Otherwise, steps forward will always be vulnerable to the bloody clawbacks we saw this year. A political strategy that doesn't center system reform is not "pragmatic."

Time for rapid, deep introspection by the town's citizenry, in my opinion. Apart from immediate change in cruise ship volume in the local government's proposal, creep is built into the scheme.

Climate modelling work (e.g. GeoMIP) suggests that SRM geoengineering could work as a temporary/emergency way to cool the climate. This certainly does not justify large-scale implementation at this stage. However, open research on SRM needs to be encouraged, not driven underground.

Sink it, over the next decade. Calling for shrinking it is ambiguous & insufficient.
Phase-out policy is the easier part. Policy development should mainly focus on making a palatable & fair transition to (most likely) less overall available energy.

New paper just dropped about sticks and carrots in climate policy: “Policy carrots alone do not dramatically reduce future emissions. Only with policy sticks are there unambiguous signals to substantially shrink the size of incumbent fossil fuel industries.”
