I think nobody should give up hope on this issue TBH! I know we are battling against multi-national corporations like Exxon and others who definitely influence govts and bribe them to "do their bidding", but there has been more exposure of corrupt practise like this and that needs to continue together with civil protests etc. Our extreme weather patterns are clearly becoming the normal and getting worse. People, qualified scientists, reputable institutions, pragmatic politicians, media etc (not just in this country btw) need to keep applying the requisite pressure to demand change "across the board" in order to seriously take on the global warming threat. Giving up or "burying one's head in the sand" is not an option IMO!!
