2022 was one other yr of disastrous and lethal climate and local weather extremes world wide, fueled partially by human-caused local weather change, the United Nations climate company mentioned Friday.
Droughts, floods and warmth waves affected folks on each continent and price many billions of {dollars}, the UN’s World Meteorological Group mentioned in its new report “The State of the International Local weather 2022.” Antarctic sea ice fell to its lowest extent on document, ocean warmth and acidity ranges reached document heights and the melting of some European glaciers was, actually, off the charts, the WMO mentioned.
“Whereas greenhouse fuel emissions proceed to rise and the local weather continues to alter, populations worldwide proceed to be gravely impacted by excessive climate and local weather occasions,” WMO Secretary-Normal Petteri Taalas mentioned in a information launch.
Taalas mentioned that present glacier melting and sea-level rise present “we now have already misplaced” on these two key indicators of the planet’s well being.

Eight warmest years on document

And whereas ranges have been increased earlier than human civilization started, the quantity of heat-trapping carbon dioxide and methane within the Earth’s environment reached their highest trendy recorded quantities.
For melting glaciers and sea-level rise, ‘we now have already misplaced’
The impacts of local weather change had been felt worldwide final yr. “In 2022, steady drought in East Africa, document breaking rainfall in Pakistan and record-breaking warmth waves in China and Europe affected tens of thousands and thousands, drove meals insecurity, boosted mass migration, and price billions of {dollars} in loss and harm,” mentioned Taalas.
The important thing glaciers that scientists use as a well being test for the world shrank by greater than 4 ft in only one yr and for the primary time in historical past no snow survived the summer time soften season on Switzerland’s glaciers, the report mentioned.
“Sadly these destructive tendencies in climate patterns and all of those parameters could proceed till the 2060s” regardless of efforts to scale back emissions of heat-trapping gases, due to the air pollution already spewed, Taalas mentioned. “We have now already misplaced this melting of this glaciers sport and sea-level rise sport. In order that’s dangerous information.”

Ice sheets dropping ice
Extra dangerous local weather information got here out Thursday: A separate report discovered the Greenland and Antarctic ice sheets at the moment are dropping greater than thrice as a lot ice a yr as they had been 30 years in the past.
