The report warns that under a 3°C warming scenario, approximately 800 million people (10% of the global population) would live on land below the projected high-tide line. It highlights that Asia is the most exposed region, with China, India, Vietnam, and Indonesia facing significant risks. The document argues that adhering to the Paris Agreement's 1.5°C target could reduce this exposure by approximately half, potentially saving many coastal megacities from abandonment or the need for unprecedented flood defenses.

  • Under a 3°C warming scenario, the high-tide line is projected to encroach upon land occupied by more than 800 million people, representing approximately 10% of the current global population.
  • Asia faces the highest overall exposure; eight of the ten largest nations at risk are Asian, with at least 600 million people exposed under a 3°C scenario. China is particularly vulnerable, with 43 million people currently on land expected to be below high tide by the end of this century, and 200 million at long-term risk.
  • Small island nations are at extreme risk; under 3°C of warming, over 90% of the current population in the Cocos Islands, Maldives, Marshall Islands, Kiribati, Cayman Islands, Tokelau, Tuvalu, and the Bahamas would live below the projected median multi-century high-tide line.
  • Limiting global warming to 1.5°C through the Paris Agreement would significantly reduce risk, affecting 510 million people compared to the 810 million affected at 3°C.
  • Current carbon emissions have already committed the planet to a global mean sea level rise of approximately 1.9 meters over the coming centuries, even if net global emissions cease after 2020.
