UK PM Boris Johnson has warned world leaders that it is “one minute to midnight” in the race to prevent global warming from reaching devastating levels. And David Attenborough has delivered a pep talk as the big climate summit that kicked off overnight. The United Nations has warned the stakes for the COP26 meeting “couldn’t be higher.” The meeting has also been described as the “last chance saloon” by Prince Charles and one of history’s most important diplomatic meetings. No pressure… Out of the blocks early is India – PM Narendra Modi is not only attending, but he has also committed his country – the world’s 4th biggest emitter of carbon dioxide after China, the US and the European Union – to a target of net zero emissions by 2070. It’s 20 years later than hoped but it is seen by some as progress. PM Morrison will deliver his address to the meeting today.
