The step change in WA

The above article demonstrates that climate change has already affected precipitation in Australia. Whether Canberra has been similarly affected is not known. But as I have previously reported the CSIRO believes, based on the statistics, that it is possible that Canberra has undergone a step change in precipitation.

They are understandably cautious: scientists usually are, and scientists working for government agencies even more so. But I think that the statistical evidence is very clear indeed. While I am unable to detect the mechanism by simply using statistical data, it is possible that a mechanism similar to that discussed in the article above is operating here.

Climate change is not some distant threat. Climate change is here.
