1: These catastrophic scenarios have historically been great exaggerations of reality.
2: The major culprit at the moment, by a long margin, is China, while the EU has actually a very good track in reducing CO2 emissions.
1. Yep, I somewhat agree. So can you please clarify your stance as to whether the current climate change situation is another example?
2. Yep, and I sincerely hope China also pulls their heads out of their collective asses. However, the UK is also not out of the woods yet [1]. Just because China has a long way to go doesn't mean any other country should be easing off the gas pedal (terrible pun, hope you'll forgive me).

i.e. If all other countries would go on a steady course of diminishing their emissions for about 1%/year like the EU has been doing for the past 3 decades, the problem will be addressed.
