Been meaning to post on Paul Durack, Susan Wijfells and Richard Matear’s work on the intensification of the global water cycle using changing ocean salinity, but Paul has written a great article for The Conversation (reproduced below). Paul and I used to give each other grief when we were both at CSIRO, so for light relief he went and did a Ph D, doing this great work in the process.

The work cracked Science magazine (full article behind paywall) and has been featured on Real Climate. It has also attracted a rejoinder in correspondence by Roderick and colleagues who maintain that the evidence of an intensified rainfall response on land is not there (all of which is behind a paywall). I reckon they’re wrong and there is growing evidence that the models are understating hydrological sensitivity. This means that droughts and floods are changing faster than projected by the models. Furthermore, I think these changes are strongly non linear as has been observed in south-eastern Australia – something that Paul is a bit dubious about (for the moment!). Anyhow, from the man himself, read on … Read the rest of this entry »
