In the Hollywood version of this, if this was an ginormous asteroid on collision course for Earth, rather than sending Bruce Willis up with a nuke in his pocket, our governments would be selling tickets for the light show, and we would be picking our noses on the beach. https://www.bbc.co.uk/news/science-environment-65000182 UN chief Antonio Guterres says a major new report on climate change is a "survival guide for humanity". Governments had previously agreed to act to avoid global temperature rise going above 1.5C. But the world has already warmed by 1.1C and now experts say that it is likely to breach 1.5C in the 2030s. (Yes, that's the 2030s, folks.) "Even in the near term, global warming is more likely than not to reach 1.5C even under the very low greenhouse gas scenario," the report states. "If we aim for 1.5C and achieve 1.6C, that is still much much better than saying, it's too late, and we are doomed and I'm not even trying," Dr Friederike Otto, from Imperial College, a member of the core writing team for this report, told BBC News. "And I think what this report shows very, very clearly is there is so much to win by trying." |  |
