If the definition of insanity is doing the same thing again and again and hoping for a different result, then surely that must apply to COP 26.

This conference has been preceded by 25 other conferences and yet again we are told that we have only minutes to save the planet.

Even the Queen who normally does not comment on such matters has been heard to say, “It’s really irritating when they talk, but they don’t do.”

After jetting into Rome for the G20 meeting, world leaders, together with business executives, the latter in private jets, then jetted to Glasgow.

Gas-guzzling convoys whisked them from the airport to their luxury hotels where they sat down to five-star meals.

Now they are wringing their hands as they discuss how in order to save the world, we hoi polloi should only take one flight a year, use electric cars, eat less meat and convert to spasmodic solar panels, wind turbines and less than efficient heat pumps.

Once again we are witnessing people preaching water while quaffing Champagne.

It promises to be one of most nauseating displays of hypocrisy of recent times.
