Fight for climate change is not lost, it's still actively being fought by scientists, entrepreneurs, content creators, journalists and activists all over the planet.
Oil companies like this narrative of lost. It was always, don't worry we still have time until now when it's leaning towards "whoopsie too late". It's not too late, we are not all going to die because of climate change.
Right now climate change is on track to be horrible for large parts of the world but there's plenty more we can fuck up beyond that.
