THE Australian government relies on various science experts to argue its case in favour of anthropogenic global warming [AGW]; people like Will Steffen, David Karoly and the ubiquitous Tim Flannery supply the scientific credentials for the government’s belief in AGW.
The economic gravitas to the government’s proposed economics measures to solve AGW are provided by their go-to man, Professor Ross Garnaut. Garnaut does come with some impressive economic academic credentials from ANU and the University of Melbourne. Garnaut also has considerable experience in private industry and is chairman of Lihir Gold, the New Guinea based gold-mining company.
In 2008 former PM Rudd engaged Garnaut to prepare an Interim Report to support the then Rudd government’s intention to introduce an ETS to solve AGW. With Rudd no longer PM, the current government under PM Gillard has commissioned Garnaut to provide updates to his 2008 Interim Report to justify the Gillard government’s intention to introduce a carbon tax to solve AGW; make of that what you will.
This article looks at Garnaut’s second update [there is a link to a critique of Garnaut’s first update below]. Garnaut’s second update looks at the science supporting AGW. This science shows warming over the recent period. That much can be agreed with, but just about everything else Garnaut’s science says, how much warming and particularly what has caused that warming, is problematic and subject to strong contrary scientific evidence. So, when Garnaut boasts in the press “I was right about climate change” that is a hollow boast.
