"Sea levels are rising faster than at any point in human history, and for every foot that waters rise, 100 million people lose their homes. At current projections, that means about 300 million people will be forced to move in the decades to come, along with the social and political conflict as people migrate inland. Despite this looming crisis, the world still lacks specific, reliable forecasts"
"The largest drivers of sea-level rise are ocean-bound glaciers whose loss is largely driven by warm ocean currents melting their undersides, a deep ocean process that will continue even as we reduce emissions. Like enormous ice cubes dumped into a glass of water, collapsing glaciers can raise sea levels precipitously. Most concerning is the Florida-sized Thwaites glacier in west Antarctica, called the doomsday glacier because it is the keystone holding back the much larger west Antarctic ice sheet."
Sea levels are rising faster than at any point in human history, and each foot of rise imperils about 100 million homes. Current projections put roughly 300 million people at risk of displacement in coming decades, with attendant social and political conflicts as populations migrate inland. Reliable, specific forecasts for timing and location of sea-level rise are lacking, and investment in understanding and slowing ice loss remains minimal. The largest drivers of future rise are ocean-bound glaciers melted from below by warm currents, and collapse of the Thwaites glacier could trigger more than six feet of global sea-level rise, displacing hundreds of millions. Emission reductions alone may not prevent such collapses, prompting efforts to treat ice as a system to monitor, anticipate, and conserve, and to explore safe, science-backed interventions.
