The thing is that, for businesses and governments, complying with the 1.5ºC goals/projections is already a monumental task. If it does happen, even though it won't be enough, we should at least get an A for effort ... too bad nature is not forgiving.

Anyway, what is still nice is that it should be easier to adapt to 3-5ºC once we're all doing something for 1.5ºC than if we were doing nothing at all, i.e. static friction is always higher than kinetic friction. I think the true covert goal at the moment is to at least get things moving and have everyone jump on it asap.

Youre right about the difficulty of the task, but should we even be considering 3 degrees of warming as acceptable? That’s a nightmare scenario for most of the global south

5 degrees is a nightmare scenario for the whole world. Albeit I think it’s far more likely if we have to finally admit we’re on the pathway to 3 degrees, many countries might independently deploy solar geoengineering projects to save their skin (especially island nations)

I agree, actions (what and to which degree needs to be done) will differ if you plan for 1.5 °C or 3 °C.

[moralestapia]

The degree (no pun intended) changes, but the kind of actions you engage with are more or less the same.

This, from a business point of view, if we talk about things like "the entire city will flood in 20 years" (which is what would happen to some places on the 5ºC pathway), then there's not really much to do, honestly.
