No, it's not and we can't even make a measurable change, it's a waste of money that could be better spent advancing nano technology and medical science that can and in time will help so many people.
We have to get past greed and waste in order to advance faster and climate change is mostly a ploy to exert control, it is not an existential threat, it's simply not and nobody can prove that it is, a 1-degree temp change over 100 years happens naturally, we can't even prove that it's man made, it's a theory, man caused climate change is only a theory.
Now pollution we need to control, forever plastics, radiation, carcinogenic chemicals and harmful airborne emissions, even bio weapon leakage, it all needs to be controlled.
