I came across this quote in the economist the other day. There are places in australia which is one of the bread baskets" in the world and in some places it hasn"t rained in 13 years. New south whales had a little rain so he borrowed money to plant his crop and now he has a problem. There is no rain and that is devastating. Also i checked the weather network the other day and they have something called climate change" and it is put up by david suzuki. He has an interesting analogy and i suggest you take a look at it. It says that the evidence is overwhelming that climate change is happening. It say that we are all in a car and heading for a brick wall and the car is speeding up and the point is that everyone in the car is arguing about where they are sitting.
