I’ve seen some mad political debates in my time, but none as bonkers as last night’s climate debate on Channel 4. It summed up beautifully how unhinged climate-change alarmism has become.

It wasn’t a debate at all, in fact. Everyone in the studio agreed that the end of the world is nigh, that mankind is polluting himself out of existence and that if we don’t take action right now against plastic straws and cotton buds — seriously — then our kids will inherit a barren planet.
