Well. The IPCC has come out with their new report saying that things are mighty bad and if we don't do something really fast, we face a world with "abrupt or irreversible" climatic effects.
Without such action, "unmitigated climate change would, in the long term, be likely to exceed the capacity of natural, managed and human systems to adapt," the Synthesis Report warns.
However, you will not be surprised to hear that Jim Connaughton, chairman of the Council of Environmental Quality, believes that things are still uncertain and although urgent action is needed, we can't set targets because we need more time to figure out what to do. I suspect this is because it might interfere with Bush's friends getting richer while the world burns.
This is an open thread.
