Geoengineering Delay of Climate Change Sea-Level Rise?

At current rates, global warming will force coastal cities to contend with about 1 meter of sea level rise by 2100, according to a 2021 report from the Intergovernmental Panel on Climate Change. But some researchers predict worse, warning that the ice sheets on top of Greenland and Antarctica, which store enough water to cause many more meters of global sea level rise, are already past tipping points. Even if humanity curbs emissions and warming slows, they say, these ice sheets may still collapse in the coming centuries. Better to begin research now on how to staunch sea level rise at its source, rather than spending billions to wall off coastal cities, says John Moore a glaciologist at the University of Lapland and an author of a white paper sponsored by the University of Chicago (UC) that proposes a radical solution.

The Whitepaper, released last week by glaciologists after a series of workshops and town halls, calls for boosting research into daring plans that would protect vulnerable ice sheets by building flexible barriers around them or drilling deep into them to slow their slippage into the sea.
