Scientists say next few years vital to securing the future of the West Antarctic Ice Sheet

A study published in Communications Earth & Environment suggests that a four-meter global sea level rise could be triggered if the West Antarctic Ice Sheet collapses, with temperatures just above present-day levels being sufficient to trigger collapse. Immediate actions to reduce emissions could still prevent this catastrophic outcome.
