From: Industrial-age doubling of snow accumulation in the Alaska Range linked to tropical ocean warming
The Mt. Hunter accumulation record. Annual (light gray line) and 21-year smoothed (black line) accumulation time series from the year 810 CE to present, constrained by 21-year smoothed error envelopes (blue shading) inclusive of stochastic, peak position and layer-thinning model uncertainties (see Methods section), including the total uncertainty range among all four modeling approaches. The inset shows seasonal trends in accumulation since 1867 with 21-year running means (bold lines). Snowfall accumulating between September and April (blue) has more than doubled, with a faster rise since 1976. Summer accumulation (April to August; red) remained comparatively stable except for a baseline shift between 1909 and 1925.
