The dramatic vanishing of polar ice sheets will cause catastrophic sea level rise that will threaten cities, according to a major new study
The climate crisis has pushed the planet’s stores of ice to a widespread collapse that was “unthinkable just a decade ago”, with Arctic sea ice certain to vanish in summers and ruinous sea level rise from melting glaciers now already in motion, a major new report has warned.
Even if planet-heating emissions are radically cut, the world’s vast ice sheets at the poles will continue to melt away for hundreds of years, causing up to three metres of sea level rise that will imperil coastal cities, the report states. The “terminal” loss of sea ice from the Arctic during summers could arrive within a decade and now cannot be avoided, it adds.
