The kids are not all right. Children born in 2020 could live through seven times as many extreme heat waves as people born in 1960.
That’s the projected generational disparity if global greenhouse gas emissions are curbed by the amount currently promised by the world’s nations, climate scientist Wim Thiery of Vrije Universiteit Brussel in Belgium and colleagues report September 26 in Science. Under current pledges, Earth’s average temperature is expected to increase by about 2.4 degrees Celsius relative to preindustrial times by 2100. While the older generation will experience an average of about four extreme heat waves during their lifetime, the younger generation could experience an average of about 30 such heat waves, the researchers say.
