Excellent Jo Chandler piece in the Age of 29 June, about many things, including the nonsense that was Climategate.
Meanwhile, in real news, the journal Nature Geoscience published a paper by American and British scientists that found West Antarctica’s Pine Island glacier is now melting 50 per cent faster than in 1994.
In an effort to better understand the hidden mysteries of ice sheet dynamics, which have obvious implications for every coast on the planet, the team also sent a submarine beneath the floating portion of the ice. It found the glacier had broken free from the ridge that once grounded it, allowing warmer waters to circulate and melt it from beneath. This had long been the theory – now they had some observed evidence.

Their collapse is a nightmare cited as one of the tipping-point scenarios scientists most fear – potentially pulling the plug to drain the western ice plateau, and possibly even destabilising the sleeping giant next door: the East Antarctic ice sheet.
The uncertainties of these processes are to blame for the wide, wild variations in anticipated global sea level rise – the hottest, most disputed topic in forecasts for a warmer world. So you might imagine that this latest insight would merit a mention. But it didn’t make the cut for publication in any Australian newspapers.
