you're being facetious. We don't "have to first lose", its just the very likely outcome is that we will lose.
That's not to say its not worth trying but that we should assume failure, otherwise you end up like the UK's Brexit negotiators who were "all-in" on the "oh they'll buckle as the time runs out" strategy and have no plan if that doesn't pan out beyond "so what now?".
The basic strategy right now seems to run on the basic belief that human-kind will figure out its slowly destroying its habitat and change accordingly. I don't think we've even managed to all figure out the extent of the destruction let alone even start to change accordingly.
What habits have we changed since the 1990s within our population to cut global carbon emissions? I'm struggling to glue a couple of things together. If I'm not mistaken, global air travel has _soared_ within that time window and everyone is just sitting on their hands under the mistaken belief that renewables will bail us out while we all still drive in a car to go to the supermarket.
