Sea level rise is accelerating.

Unstoppable ice collapse is set to trigger flooding of coastal cities, creating 100s of millions of climate refugees by 2037.

Dangerous Sea Level Rise Will Occur in Decades, Not Centuries

Even scientists who question findings say 'we ignore James Hansen at our peril.'

Collapse of Pine Island and Thwaites would set off a catastrophe:

'All over the world, high tides would creep higher, slowly burying every shoreline on the planet..

All this could play out in a mere 20 to 50 years — much too quickly for humanity to adapt'grist.org/article/antarc…

Scientists are 'unable to rule out the very dire possibility that things could get a whole lot worse. All the news out of Antarctica is just one big reason for us to act even more decisively.' grist.org/article/doomsd…

By 2060, about 1.4 billion people could be climate change refugees due to rising ocean levels. Those who once lived on coastlines will face displacement and resettlement bottlenecks as they seek habitable places inland. news.cornell.edu/stories/2017/0…

There is enough ice in the drainage basins in this sector of Antarctica to raise the height of the global oceans by 28m - if it were all to melt:

'Nasa says it has detected the first signs of significant melting in a swathe of glaciers in East Antarctica'bbc.com/news/amp/scien…

'Researchers say they're "astounded" by the acceleration in melting and fear for the future of cities on coasts around the world.'

It's not just millions at risk within decades, it's 10s or 100s of millions. bbc.co.uk/news/amp/scien…

If sea level rise rates continue to double every 7 years or so, we're looking at 2035 not 2050.
