Tackling global warming expressed as planting trees.

The efforts of most countries have fallen well short of what is required if humanity is to prevent the average temperature rising above 1.5 deg. C, but it seems to me that Trump is actively working towards dismantling even the modest attempts to halt global warming that America has put into place thus far. America is not the biggest emitter of Co2, China is, but by ignoring the threat of global warming it sets a dangerous precedent that many countries are sure to emulate.
