The stakes at COP26, the U.N. climate summit that begins Nov. 1 in Glasgow, couldn’t be higher. U.S. climate envoy John Kerry has called the summit the world’s “last best hope” to avoid the worst consequences of climate change. Over two weeks, some 20,000 delegates representing 195 countries will try to resolve significant differences on how the world should cut its greenhouse gas emissions, with the aim to “keep 1.5°C alive.” That is, to meet the Paris Agreement’s target of limiting global average temperature rise to 1.5°C over the preindustrial era by 2050, after which point climate change will likely reach catastrophic proportions .
