Although
globally averaged annual temperatures warmed about 1 deg F since the early 1900s (viewed as rapid by paleoclimatologists and geologists), regional climate station annual temperatures in northern Minnesota show warming by several degrees F since the early 1900s.
Granted, while
the globally averaged annual temperatures for the years since the record warm year of 1998 have not exceeded the 1998 record, the global temperatures since 1998 have remained high, ranking as the second, third and fourth warmest years of the last 125 years (and quit possibly the last 2,000 + years).

Not exact matches
Substantial reductions in the extent of Arctic sea ice since 1978 (2.7 ± 0.6 percent per decade in the
annual average, 7.4 ± 2.4 percent per decade for summer), increases in permafrost
temperatures and reductions in glacial extent
globally and in Greenland and Antarctic ice sheets have also been observed in recent decades.
... Polar amplification explains in part why Greenland Ice Sheet and the West Antarctic Ice Sheet appear to be highly sensitive to relatively small increases in CO2 concentration and global mean
temperature... Polar amplification occurs if the magnitude of zonally
averaged surface
temperature change at high latitudes exceeds the
globally averaged temperature change, in response to climate forcings and on time scales greater than the
annual cycle.
