ON 29 June, the village of Lytton in British Columbia recorded a temperature of 49.6掳C, smashing Canadian records. The following day, fire swept through it, razing much of it to the ground.
Last week鈥檚 deadly heatwave in North America聽 is far from the first extreme weather event to shake the world. Apocalyptic blazes hit California last year and Australia in late 2019.

Climate attribution studies show that both earlier events were made more likely by climate change. We hardly need the verdict on the North American heatwave to tell us the risks of continued inaction.
Yet that it is what we are getting. Despite the damage and loss of life, Australia鈥檚 fires for national action on carbon emissions. It seems unlikely that Lytton鈥檚 destruction will lead Canada to rethink the emissions plan promised in April, which is still of the Paris Agreement and limit climate change to liveable levels.
Every failure to act now comes with a human cost. A Intergovernmental Panel on Climate Change report said, baldly: 鈥淟ife on Earth can recover from a drastic climate shift by evolving into new species and creating new ecosystems. Humans cannot.鈥�
Each failure also comes with economic costs, as we need to spend more adapting to a warmer world as well as mitigating the emissions driving it. As our columnist Annalee Newitz points out, we are only just starting to confront how we rebuild infrastructure and social systems to cope with the damage already wrought.
Hope that we can avoid the worst effects comes from the bottom up 鈥� in the youth movements calling for change, the , the firms plans and in court judgments wringing action from recalcitrant governments and firms.
But governments must empower all those movements from the top down, too, if we are to ensure sepia-tinged hellscapes don鈥檛 become a norm.
