A more intense global water cycle

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 »

Apparently the selection of a few lead authors who are not hoary old farts who have gone emeritus, disqualifies the IPCC from saying anything useful.

Preferred IPCC author by those who deny the IPCC is of any use – no young scientists here, thankyou!
