It may well be that the forest climate has been degrading over 40 or so years. Personally I'm a believer that industrial inefficiencies and other human factors such as habitat destruction are contributing to climate change.
However. A one year dry spell does not count as "climate change" especially when it's clearly attributable to a strong Southern Oscillation.
Seriously, not everything is attributable to bloody Climate Change. Stop crying wolf, show some good science, and the message gets stronger instead of being diluted to homeopathic proportions!
