The Arctic has warmed nearly four times faster than the globe since 1979
evidence
Observational analysis over 1979-2021 finds Arctic warming close to four times the global mean rate, higher than the two-to-three times commonly quoted previously, with the ratio sensitive to how the Arctic region is defined. V55 VERIFICATION BASIS: the paper was not opened during production - no research channel was available. The title, journal and DOI are given from the producer's prior knowledge and must be confirmed before publication; the ratio should not be quoted more precisely than "close to four times" on this basis.
A evidence is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
