Changing temperatures around the world have led to several climate emergencies so far in 2022, from historic flooding in Pakistan that's displaced millions of people to the rapid melting of a major glacier in Antarctica.
Parts of the world are expected to experience severe weather for the rest of the year and into 2023, as part of a rare "triple dip La Niña" event, according to the World Meteorological Organization .A "triple-dip" La Niña is a multiyear cooling of the surface temperature of the equatorial Pacific Ocean, which can cause droughts, fierce winds and heavy rainfall.
"It is exceptional to have three consecutive years with a la Niña event. Its cooling influence is temporarily slowing the rise in global temperatures - but it will not halt or reverse the long-term warming trend," Petteri Taalas, the secretary-general of WMO, said in a recent report. The weather has caused droughts in North and South America and equatorial eastern Africa. La Niña is also linked to floods in Asia, such as the devastating floods Pakistan has endured since June, Seager said.
