Climate change is rapidly transforming the Arctic into an almost unrecognisable new region , the National Oceanic and Atmospheric Administration ’s annual Arctic Report Card has rule .
The story , free Tuesdayand author by 147 scientist from 11 countries , is full of cheerful update on just how rapidly clime change is spay one of the earth ’s most sensitive regions . For case , the story find that 2022 had the sixth warmest air travel temperature ever recorded in the Arctic ; the past seven yr have together been the warmest since records get in 1900 . To make matter even sorry , 2022 marked the twenty-fifth consecutive twelvemonth that the Greenland ice shroud , which “ has immediate and global influence on sea grade rise , ” has ended the twelvemonth smaller than it begin . Fun !
This is the 17th year that NOAA has been compiling this comprehensive , match - review research on the Arctic , and the length of the report identity card format really helps to drive home the gravity of some of these annual metrics that , in closing off , do n’t seem as extreme as in other age . In 2022 , sea ice covering fire in the Arctic reverberate after disc lows in 2021 ; 2022 ice level , however , were still far below the median observed from 1981 to 2010 . likewise , vegetation growth on the tundra — what ’s bang as greening — was down in parts of the Arctic compare to 2021 and 2020 , but this year was still the fourth - bad for greening since scientists start taking measurement in 2000 .

Even when some certain conditions seemed to be trending in a good direction , the large - scale changes going on in the region can quickly counteract that . Charles Percy Snow accumulation across the Arctic was above norm during the 2021 - 2022 wintertime season , but the onset of spring and warmer temperatures apace melted all that extra snow , creating a snow - barren spring in Eurasia that was 30 % to 50 % farsighted than common . cold temperatures at the start of the summer , meanwhile , imply that the Greenland water ice sheet did n’t melt very much through the season . Come September , however , the sparkler sheet have an “ unprecedented ” melting case during a stark heatwave that direct out more than one - third of the frappe sheet ’s entire surface region .
This composition is the first Arctic Report Card to turn to hurriedness , a notoriously difficult set of trend to quantify in the realm . clime change is helping increase atmospherical wet which , in the main , has give to great overall hurry globally , create heavy rain and snow events . In the Arctic , the report finds , the menstruum from September 2021 to October 2022 was the third - wettest year on record since 1950 ; the only two wetting agent years were in 2018 and 2020 . This break in precipitation , the report finds , also correlate with regions in the Arctic where sea ice has become scarcer , which countenance storms strengthen over warm and open sea water .
“ On the fringes of the [ Arctic ] region … in the next few X we ’re sound to see a major transition from snow to rain , ” John Walsh , a research professor at the International Arctic Research Center and one of the authors of the report card , said at a press group discussion at the American Geophysical Union league in Chicago on Tuesday . “ Rain will become the predominate hastiness annually . ”
All this mess in the Arctic is not only change ecosystems and wildlife but also seriously impact human life and culture . Indigenous folks inhabit in the neighborhood are experiencing monumental and wide - scurf changes to their room of life , as account in a chapter of the report bill of fare that advise policymakers to work more nearly with Indigenous knowledge holder on root . And many of the world ’s major powers are taking advantage of the changes in the north : satellite data shows increasing merchant marine in areas of the Arctic previously covered by ice , opening up raw routes for global craft and exposing ecosystem to newfangled kinds of hurt from human activity .
“ The wildcat is in the sign of the zodiac , ” NOAA Administrator Rick Spinrad said at the AGU league , speaking of a late trip he ingest to Alaska . “ By that I stand for that the climate impacts we ’re examine in Alaska — melting permafrost that ’s warping roads , melting ice that ’s forcing entire autochthonous community to relocate , warming waters that are forcing fish to migrate and having ripple effects for the entire Alaskan seafood manufacture , fire time of year that last far longer than they ever have — that ’s just a shot of what parts of the Lower 48 might expect in the very near future . ”
