[Published on The Drum 20 May]
Recently climate sceptics Anthony Cox and David Stockwell published an opinion piece on the ABC’s The Drum claiming climate scientist James Hansen had “admitted” climate models have been wrong, and that human-caused global warming was therefore in doubt. The article contains basic misrepresentations of Hansen and of the substance and implications of a draft paper by Hansen.
The Hansen paper does not weaken the case that humans are the main cause of global warming. On the contrary, it suggests we have unwittingly and temporarily shielded ourselves from the full effects of our activities.
