In 2022 the water cycle was dominated by heat ocean waters within the western Pacific, jap and northern Indian Ocean as air temperature over land adopted the long-term warming pattern, and air humidity declined.
This in flip fuelled excessive pure disasters throughout the globe.
Warm ocean temperatures led to the formation of a extreme heatwave in South Asia early within the 12 months, adopted by an excessive monsoon that induced huge floods in Pakistan.
The 12 months additionally coincided with the rise of “flash droughts” – dry spells which quickly develop inside a number of months following extreme heatwaves – throughout Europe and China.
Lead creator Professor Albert van Dijk warned occasions like flash droughts and excessive floods, will develop into extra frequent because the water cycle shifts.
“If La Niña or El Niño patterns are going to stay around longer in future, that is going to cause a lot of trouble, with worse, longer droughts and worse floods alike,” he stated.
“It’s a safe prediction that we will see more and more of these heatwaves and flash droughts.
“We additionally see proof of the influence of worldwide warming on glaciers and the water cycle in chilly areas, and actually melting glaciers contributed to the Pakistan floods.
“That will continue until those glaciers are gone.”
One cannot discuss 2022 with out making reference to the very fact it was the third La Niña 12 months in a row.
While three consecutive years are uncommon it is not solely unprecedented, however because the water cycle shifts it stays unclear whether or not back-to-back occasions are actually the norm.
“The jury is still out on whether those three La Niña years were a statistical fluke or the first signs of something more sinister,” Van Dijk stated.

To collate their findings researchers mixed water measurements from 1000’s of floor stations and by satellites, producing up-to-date data on rainfall, air temperature and humidity, soil water, river flows and the quantity of water in pure and synthetic lakes.
