Targets are a hit and miss affair and governmental and international targets more than most. The problem is that once a target is set the underlying reason for the target is forgotten and the target becomes a means in itself. Continue reading

Signing up to targets at Copenhagen will be meaningless

As the world’s nations prepare to negotiate at Copenhagen in December the specific negotiators will be concentrating on targets. Each major nation will have a different idea about which target is right for it, and each small nation will have more ambitious targets than each large nation.I expect that at the end of the negotiations various leaders will attend and as a result of their attendance claim credit for a deal that has saved the world because the nations of the world will have signed up to a series of targets. Hooray! Unfortunately most of targets will be Continue reading

Picturing climate change processes and understanding the puzzle

It can be hard to picture things of complexity. The old puzzles about how long it takes if three people dig a hole if A works twice as hard as B but C works 30% of more than A but  goes to have a cup of tea for half an hour etc, need (for most of us) pencil and paper to work out. Even then we often do not get the right answer We cannot easily visualise the processes that happen because they are rather complex. So it is with climate change and that is probably the reason why our leaders and most of us have such a relaxed attitude to it. Continue reading
