There are two fast indicators to look at for. First, how formidable will the Biden administration be in its emissions reductions targets? It’s underneath strain from advocacy teams to scale back emissions by 50 p.c by 2030, in comparison with 2005 ranges.

And second, how a lot cash will the US present to assist poor international locations adapt to the calamities of world warming and shift their economies away from fossil fuels?
