I can tell you, a 2C hotter world is a death sentence for countries like mine.” Five years ago this week, almost all of the world’s countries pledged to limit global warming to “well below” 2C above pre-industrial levels and to strive to keep temperatures at 1.5C by the end of the century as part of the historic Paris Climate Agreement. Cutting emissions at the pace needed to hit net zero by 2050 will not be an easy task for any country, said Dr Hausfather: “We’re not just talking about building a lot of wind and solar, we are talking about decarbonising every single sector of the economy: agriculture, industry, transport, aviation.” The IPCC’s landmark 1.5C report examined the possible pathways the world could take to limit global warming to 1.5C by the end of the century. “While the IPCC special report on land highlighted these important risks and trade-offs, it also shows if you implement best practices, these trade-offs can be avoided.” However, even if efforts to cut emissions are ramped up and negative emissions technologies are developed at scale, it would still not guarantee that global warming is kept to 1.5C, he added. “It would be great to limit global warming at 1.5C, but if we end up at 1.6 or 1.7C, the world doesn’t end.
