Climate change is real. Obviously, because the climate has always been changin. why would it stop today?
Are humans responsible? Not clear. It could also just be a natural cycle. Or humans could actually have stopped the ice age that should have already started. As you can see opinions diverge.
Can we stop climate change then?
Producing, driving and recycling electric cars has about the same impact on the environment as a normal gasoline driven car. Raising oil taxes is 1. way too slow and 2. there are the chinese... And most importantly: all those subventions cost a freakin load of money and wether they will have the desired effect is all but certain.
I say we are investing in the wrong place. The right place to invest is the next generation, globally. One of our children (or actually many) will be the genious who finds an actual solution to the problem, on which we are just wasting our money senselessly.
