evidence: One difference is the faster pace that land areas are warming compared to the ocean. But perhaps the biggest outlier is the Arctic, which is warming more than two times faster than the global average (pdf). [...] The chart below shows annual average surface temperatures, relative to 1951-80, for the whole planet (blue line) and the Arctic (red). Since around 1990, the Arctic is clearly warming faster than the rest of the planet. Annual average surface air temperature anomalies for the Arctic (red line) and the global average (blue) from 1950 to 2020. Linear trend lines (dashed) are also shown over the 1990 to 2020 period.

Back in 1896, the Swedish chemist Svante Arrhenius noted that "those places that alter their albedo through the progression or regression of the snow-covering…will probably remove the maximum effect [of increased carbon dioxide] from lower parallels to the neighbourhood of the poles".
