Doomsday Glacier may collapse sooner than expected as scientists ... (Economic Times)

A new study suggests the Thwaites Glacier in Antarctica, known as the "Doomsday Glacier," may collapse sooner than expected, leading to a potential ...

The melting occurring in the glacier is complicated, and there is a reason for greater concern, according to senior climate and energy reporter In a reversal of events due to climate change, the ACC is getting faster, just as most climate models predicted. The views expressed here are that of the respective authors/ entities and do not represent the views of Economic Times (ET). Despite the alarming news, there is some optimism about the Thwaites Glacier – the data obtained from the studies show there is a reason for concern and alarm, but it also leads to additional questions and additional worries. However, this goal is not realistic as we're already at 1.2 C, and if all global pledges are met, we would go only to 2.4 C.

Antarctica's 'Doomsday' glacier is 'in trouble' (Sky News)

Antarctica's vast Thwaites glacier, which could push up global sea levels by half a metre because of its melting ice, is "in trouble", according to ...

What we have found is that despite small amounts of melting there is still rapid glacier retreat, so it seems that it doesn't take a lot to push the glacier out of balance." It shatters," said Ms Schmidt, lead author of one of two studies published yesterday in the peer-reviewed journal Nature. "That's how the glacier is falling apart. The more the glacier breaks up or retreats, the more ice floats in water, displacing water levels like an ice cube in a glass of water. "If an ice shelf and a glacier is in balance, the ice coming off the continent will match the amount of ice being lost through melting and iceberg calving. The glacier retreating - whereby ice breaks off into the sea - is a more severe problem than the melt, Mr Davis said.

D. Wake, D. Spears, D. Nicholls, D. E. They found the staircases, called terraces, as well as crevasses in the ice base are melting rapidly. The observations Icefin made of the seafloor and ice around the grounding zone provide more detail on the picture of how melting varies beneath the ice shelf. Over a nine-month period, the ocean near the grounding line became warmer and saltier but the melt rate at the ice base averaged 2-5 m per year: less than previously modeled. The MELT team undertook observations of the grounding line (where the ice first meets the ocean) beneath the Thwaites Eastern Ice Shelf in order to understand how the ice and ocean interacts in this critical region. Much of the ice sheet is below sea level and susceptible to rapid, irreversible ice loss that could raise global sea-level by over half a meter within centuries. Results show that although melting has increased beneath the floating ice shelf, the present rate of melting is slower than many computer models currently estimate. It is one of the most critical glaciers in West Antarctica, and its potential collapse could trigger a significant rise in sea level, which could have catastrophic consequences for coastal communities worldwide.
