Surely, if there is any improvement in so-called climate change to be made, we all right across the world need to sing off the same hymn sheet.
If I decide to do my bit, install solar panels (which I've already done), buy an electric car, (which I can't afford to do) and stop flying round the world (which I don't do) everyone else needs to do the same and you and I know that simply isn't going to happen.
