The return last week of opposition energy and emissions-reductions spokesperson Dan Tehan from his fact-avoiding mission to the US shows this nonsense has gone too far.

Some of the incessant non-journalism in the Murdoch press in the past few months would verge on the comical if the issue were not so serious. Offshore wind farms kill whales; onshore wind farms kill endangered birds; discarded solar panels are clogging landfills; electric-vehicle batteries are exploding, causing fires; electric vehicles are smashing up roads and paying no fuel tax; on and on it goes. Any grab-bag argument against moving from fossil fuels to renewables will be used by the fossil quartet to keep the profits rolling, whatever the long-term damage.
