An excellent article that raises some very important points. It is very easy to be a pessimist in this field and looking back at my own writing of late I can see that happening and must make some changes there. The problem I see in this up beat scenario is the link between politicians and big oil. That is the link that needs to be broken to bring about change and that may take some aggressive action on the part of green activists. If we take the pressure off for even a second they will kick this into the long grass
