Climate scientists say the atmospheric warming, mainly from human burning of fossil fuels, is causing ever more extreme and damaging weather including droughts, flooding and dangerous heat. One projected track based on what countries promise to do by 2030 is up to 2.6 degrees Celsius, a tenth of a degree warmer than before. And even the analysts’ most optimistic scenario, which assumes that countries all deliver on their promises and targets, is at 1.9 Celsius, also up a tenth of a degree from last year.
