SOME species of Australian birds are shrinking and the trend will likely continue because of global warming, a scientist said.
Janet Gardner, an Australian National University biologist, led a team of scientists who measured museum specimens to plot the decline in size of eight species of Australian birds over the past century.
The research, published last week in the British journal Proceedings of the Royal Society B: Biological Sciences, found the birds in Australia’s southeast had become between 2 per cent to 4 per cent smaller.
Over the same century, Australia’s average daily temperature rose 1.3 degrees Fahrenheit (0.7 deg C), with the sharpest increase since the 1950s.

Fascinating. But an association of trends does not prove causation. Did they publish evidence that warming is the culprit?
