If we (society as a whole) had started switching to renewables when Greenpeace first started campaigning for them, I suspect we wouldn't have the climate emergency that makes nuclear look attractive.
It's hard to expect them to change their stance just because we failed to follow their lead for decades.
Focus follows mouse. And programs that raise the window when you click in it? Unusable.
I suggest you read up about Deism.
As a Brit, I fully support the idea that we should rejoin with full commitment. No way do I want a repeat performance where we can be taken out by a minority of gullible idiots.
I believe that the more tolerable climate predictions assume that not only will we cut emissions but that we will also find a way to remove significant amounts of CO2 from the atmosphere.
So you are both right.
I liked your first iteration better, to be honest. The left-hand one here is too squat. The right-hand one is cute, though - people are not wrong about that.
If you think of it in terms of carbon footprint and what your children's future is worth to you, then the train wins no contest.
