I’ve had the link for the Blog Action Day in the sidebar for what seems like months so I had better make sure that I do actually post something on global warming.  Whether you adhere to the view that it is caused by human interaction or that it is natural phenomenan , I think it is pretty clear that it is happening.  I’m usually of the view that whatever I can do will make little or no difference but lots of small actions can be greater than one large action.  So go and put a brick in your cistern, don’t leave the water running while you brush your teeth and change your wash cycle to cold – it works just as well!
