This Antarctic glacier dramatically retreated., then, its ice shelf totally collapsed. | Space
Though Cadman Glacier has been thinning since the early 2000s — or possibly even as far back as the 1970s — the team suggests that warmer-than-normal ocean temperatures in 2018 and 2019 (exacerbated, in part, by human-driven global warming) likely accelerated the process, weakening the ice shelf to the point of collapse. Because ice shelves typically buttress the land-based part of a glacier, it's now expected that Cadman Glacier will lose water more rapidly. Currently, it drains some 2.38 billion tons (2.16 billion tonnes) of ice into the ocean annually, and that rate of flow will likely increase. Such glacial draining directly contributes to sea level rise, which threatens coastal regions across the globe.
