UN chief António Guterres warned the COP27 summit that humanity must cooperate or perish. He warned world leaders, ‘We are on a highway to climate hell with our foot still on the accelerator.’ https://www.bbc.co.uk/news/live/science-environment-63330171 Rishi Sunak said the war in Ukraine and rising energy prices globally are no reason to go slow on climate change. They are reasons to act faster. Boris Johnson and Emmanuel Macron also urged world leaders to deliver climate justice. The UN said progress on cutting global warming emissions has been ‘woefully inadequate’ since COP26 last year. The planet has warmed 1.1C since pre-industrial times. Scientists say rises must only be 1.5C by 2100 to avoid the worst effects. Continuing current policies would cause a higher rise of 2.8C.
