The climate shifts paper on non-linear anthropogenic climate change in SE Australia with earlier descriptions here and here, has been published in the Journal of Geophysical Research. We had plans to make it open access but must not have paid the invoice yet, so it’s behind a paywall here (pdf). If you can’t get access, get in touch with me via comment below or email (firstname.lastname at vu.edu.au) and I’ll send a reprint.
Following is an edit of the draft press release that should go out in the next week or so. The press release implies that this pretty much goes on everywhere – not just SE Australia. That’s what I believe from further work currently underway – the ocean runs the climate system and the atmosphere doesn’t warm quite the way people assume it does. The energy from greenhouse warming goes into the ocean first, then is re-emitted periodically into the atmosphere. The atmosphere doesn’t warm in situ (or not yet to any significant degree). It may later under increased radiative forcing, but at the moment the ocean is pretty much running the show. This pattern of non-linear change fits in with palaeoclimatic evidence from the region that I’ll get round to describing some time.
