This winter, now finally ending, has seen disturbing early signs of the Earth’s climate starting perhaps to go out of control. The fierce cold snap in the UK occurred because the Arctic’s normal weather came down here; meanwhile, the Arctic was off-the-scale warm.

It’s time we faced up to reality: humanity is almost certainly going to have to learn to live in a world that has been radically damaged and transformed by human-triggered climate change. We are – virtually all of us, either softly or (less often) explicitly – in climate denial. The greenhouse gases we have polluted the atmosphere with have already set us down a path of serious and possibly irreversible environmental disruption, and the prospect of technocratic rescue is as unlikely as it is worrying on its own terms.
