No geek or tech shindig is complete without an address from a more or less completely bonkers environmentalist and the South-by South West festival in Austin Texas has gone the full 12-Gore this year.
It's always interesting to see what scattergun wildness emerges from the top of Mr Gore's head. Is the Arctic going to look like the Bahamas by next Tuesday? Are hurricanes about to sweep us off to the land of Oz? Are polar bears about to sprout flippers and swim off to Clacton?
Mr Gore does not disappoint. In his talk he apparently claimed that ISIS are a symptom of anthropogenic climate change, made wild claims about the links between extreme weather and carbon dioxide and rounded things off with a call for people who disagree with him to receive unspecified punishments.
Remind me. Was it Mr Gore who went off to live in a yurt in the north of Scotland or am I thinking of someone else?
