May. 28th, 2024 02:46 pmEarly aerial expedition photos reveal 85 years of glacier growth and stability in East Antarctica.
... the stability and growth in ice elevations observed in terrestrial basins over the past few decades are part of a trend spanning at least a century...
Такой вот афронт вместо того чтобы изо всех сил таять и угрожать человечеству неминуемой гибелью. А виновато конечно глобальное потепление.
While previous research on Antarctic snowfall found no statistically significant changes since the 1950s, recent studies utilizing compiled data on ice core records indicate increased Antarctic-wide snow accumulation during the past 200 years, with links to atmospheric warming, ozone depletion, and a positive shift in Southern Annular Mode (SAM).

Date: 2024-05-28 08:25 pm (UTC)Despite large variations in size and characteristics, all six glaciers in Lützow-Holm Bay experienced a net retreat between 1937 and the 1980s, when they reached an almost simultaneous minimum (Fig. 2) associated with a complete break-up of fast ice in the bay35,46. Another smaller retreat phase occurred around the mid-2000s, with the exception of Shirase, and again during 2016-1847. By far, the largest fluctuations are observed at Shirase Glacier with a total range of almost 90 km in the ice-front position from its 1963 maximum to its minimum in 1988. In contrast, Langhovde and Hovdebreen Glacier show frontal variations of less than 1 km between 1937 and 2023. Since the retreat in the 1980s, all glaciers except Langhovde and Honnörbrygga have, at some point, advanced to a similar marginal position or even extended beyond their extent recorded in 1937. The frontal collapse of Honnörbrygga Glacier from 1937 to 1956 was observed in 196442, but has never before been quantified. From 1956 to 1974, Honnörbrygga Glacier retreated an additional 4.5 km, resulting in a total retreat of more than 10 km. Since 1974, the glacier has been able to regrow less than half of its total retreat. From its current position, it would require 17 years of uninterrupted advance at its current flow speed in order to reach its 1937 maximum extent.
а на єтой кратинке даже наглядно видно по сравнению с 1930

Многие изменения там, кстати, были напрямую связаны со сменой команд в главном офисе — как в сторону запретительную, так и в послабительную.
