Editor's note

We are on track to reach 1.5°C of global warming within 16 years, according to new data. H. Damon Matthews, Glen Peters, Myles Allen and Piers Forster explain why this is an important threshold: it will bring a rise in weather extremes like heat waves and extreme rainfall. There’s also the danger that, as the world inches closer to 2℃ warming, there’s the risk of irreversible ice sheet loss. This will drive sea levels up and wipe out nearly all the world’s corals.

Meanwhile in Africa, while a lot of attention has been given to agriculture and how changing weather patterns will affect output, there’s not been much focus on how small and medium businesses will be hit. Kate Elizabeth Gannon and Declan Conway reveal how even small changes in rainfall will interrupt cities’ water and electricity supplies, with major consequences.
