Indeed, what could go wrong...

The author wants the scientists to be involved in the coming COP27, as if they were not already. As if no technical anf scientific solutions had been provided to climate change!

Plenty of solutions have been found already. We absolutely know how to resolve this issue on the technical aspects ; this doesn't mean that no research and development is needed: we can and will come up with even better solutions.

But we already have the solutions. No technical challenge here, just a political challenge: decide how to share the costs.

Because we are lazy and don't understand what game theory tells us about the current stand-still. This is a game where each country would benefit the most if it succeeds doing the least - as long as the others do enough.

Hence the need for a political COP27: the only issue is to find a consensus and start acting promptly at the required scale (which is a big one, but much smaller than WWII for example on the economic side).

Geo-engineering is a quest for the silver bullet.

As if technology had ever provided a solution to a political issue... It hasn't. When it looks like it has, it's always because the policies are embbeded into the technogly: cf "code is law" for example.
