I dont pretend to know enough about the science to argue on the internet about it, but I know with absolute certainty that if we're all going to burn then there's nothing the EU or anybody else can do about it. China, India, rest of the developing world don't even pretend to care. Arabs wish to encourage fossil fuels for obvious reasons. Americans say they care, but have no political will to change (and they still think a 3 litre V6 is a small car).
The only ones who are interested in change are the Europeans and some of their former colonies ie Australia and NZ, and even if they turned the lights out completely tomorrow in all those countries it would barely even slow down let alone stop the climate change apocalypse thing.
