Britain’s Prime Minister Boris Johnson has opened the UN climate summit in Glasgow, following a bagpipe performance and a poetry recitation.

He reprised the words of teenage climate activist Greta Thunberg, who described the words of world leaders who aren’t committing to climate action as “blah, blah, blah”.

Addressing an audience that includes US President Joe Biden, India’s Prime Minister Narendra Modi and Sir David Attenborough, Johnson said the world is facing a James Bond-like doomsday scenario where the clock is ticking down on life as we know it.

“The longer we fail to act the worse it gets and the higher the price when we are eventually forced by catastrophe to act,” he said.

“It’s one minute to midnight on that doomsday clock and we need to act now.”

He told world leaders they needed to deliver on the promises they made in Paris in 2015 to arrest global warming.

“All those promises will be nothing but ‘blah blah blah,’ to coin a phrase, and the anger and the impatience of the world will be uncontainable unless we make this COP26 in Glasgow the moment we get real about climate change, and we can,” Johnson said in his opening speech.

He says it will be too late for our children tomorrow if the world does not act now.
