I have heard a lot about global warming, and while it would seem that there is good evidence that the world is getting warmer, the evidence as to the size of the human contribution is not clear, or indeed if it is possible to correct the problem. On one hand I have been told that it takes a number of years for to-days CO2 emissions to get up high in the atmosphere, which if the case anything we do now will not be felt for some time. On the other hand it would be foolish to ignore it totally.
