Global lockdowns have lowered emissions but longer-term changes needed, say scientists
This year is on course to be the world’s hottest since measurements began, according to meteorologists, who estimate there is a 50% to 75% chance that 2020 will break the record set four years ago.
Although the coronavirus lockdown has temporarily cleared the skies, it has done nothing to cool the climate, which needs deeper, longer-term measures, the scientists say.
