Thunberg, Attenborough and the rest are telling us we are doomed in the next few years, they are proposing remedies that cannot possibly be achieved. CO2 emissions are still rising we are doing nothing effective to counter that, nor are we likely to.
We did see a temporary drop in CO2 during Covid where travel and consumption was severely restricted, if we believe in “man made” climate change those are the type of changes that are needed.
There is no chance of that happening because although we talk about changing we do nothing.
