Stewart Franks supports my earlier claim that the current dought in the Murray-Darling Basin cannot be attributed to climate change. It can be more accurately attributed to the 2002 El Niño event and there is no convincing evidence increased frequencies of such events can be linked to climate change. In the past such events have been bunched at high frequencies. An excellent older post on this same issue is at RealClimate.

An article from The Economist, provides a pessimistic assessment of the medium term implications of climate change for developing countries and a strong argument for emphasising the use of adaptation policies. This new emphasis is a sign of increasing pessimism in climate change debates.
