I didn't say its Trump fault. Everything was already going to shit before him. But as I said it doesn't help not to even try.
Trump said he pulled out of the agreement because it was unfair to USA, which means he didn't even understand the agreement.
Tech is not the problem, its already there, and if there was a stronger will to make a difference the tech would be cheaper faster.
But as always things have to go extremely bad before people realize its enough, and when it comes to climate change, it might not be that easy to reverse after the damages are done. But its a complex matter, I hope we get enough shit so that countries are forced into action before its way too late. We'll see. Maybe China will try to fuck with USA by becoming more green, just to collect some pr points :D
