Most Antarctic ice shelves face long-term threat under worst-case global warming scenario

Antarctic Ice Shelves Under Threat

The survival of Antarctic ice shelves, crucial in sea level rise, depends on greenhouse gas emissions levels, according to a study published in Nature.

An international team of scientists modeled the future of Antarctica's main floating ice shelves, which absorb part of the ice flow toward the ocean, limiting sea level rise.

Researchers found that the long-term stability of these ice shelves heavily depends on reducing human-caused greenhouse gas emissions, assessed through several emission pathways from the IPCC's 2021 report.

The level of greenhouse gas emissions will determine the fate of ice shelves in the centuries to come.

The study highlights the importance of mitigating climate change to preserve the ice shelves and prevent further sea level rise.
