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 in 2016.
Heat records have been broken from the Antarctic to Greenland since January, which has surprised many scientists because this is not an El Niño year, the phenomenon usually associated with high temperatures.
This January was the hottest on record, leaving many Arctic nations without snow in their capital cities. In February, a research base in the Antarctic registered a temperature of more than 20C (68F) for the first time on the southern continent. At the other end of the world Qaanaaq, in Greenland, set an April record of 6C on Sunday.
