BOM amd the CSIRO have produced the State of the Climate – 2012 report. BOM has a handy summary summary and link to the brochure. The CSIRO site has some added interviews. I’ve extracted two images. First is the relentless increase in ocean heat content:
Second is the rainfall pattern for April to September from 1997 to 2011:
According to the report we can expect the same only more so in the future.

Substantively the post outlines the carbon budget approach to climate stabilisation which gives prime place to carbon equity. If Australia wants to show leadership in climate change internationally we should seek zero net emissions by 2030. We would still blow our equitable carbon budget which requires zero emissions by 2019, but with that kind of leadership we should get away with it. Also we should use our land and our forests to create carbon sinks in order to then go negative in net emissions.
The reprised post is below the fold. Continue reading Climate crunch: the fierce urgency of now
