AS IF Al Gore's last apocalyptic PowerPoint presentation wasn't boring and deceptive enough, he had to go and do it all again - for a marathon 24 hours.
A farrago of spurious connections, conspiracy theories and misrepresented facts as outlandish as any doomsday cult's, the former US vice-president's Climate Reality Project finally ended at 10am on Friday.
"The climate crisis is happening now and it's happening fast" was the message.
Gore and 24 presenters whizzed through slides of bushfires in Victoria and Russia, floods in Queensland and Pakistan, droughts in Texas and France, drowning people in China, starving children in Africa, singed koalas in Australia.
"Every extreme weather event for the past year was caused by man-made global warming and much worse is to come. The new normal is setting in ... it's the planet telling us we can expect more wacky weather in the decades to come if we don't do something about climate change," he said.
