‘It ain’t what you don’t know that gets you into trouble. It’s what you know for sure that just ain’t so.’

That quote, attributed to Samuel Clemens’ alter ego Mark Twain, sums up so much of ‘collective wisdom’ in the world today. Some claim the quote originated before his time but he’s one of my favourite boyhood authors so I’ll go with him; nowhere is it more apt than with the Western world’s current obsession with ‘climate change’.
