When global warming stops, seas will still rise

  • Even if humanity caps global warming at 1.5°C, sea levels will continue to rise for centuries, threatening cities currently home to half a billion people.

  • Current atmospheric CO2 levels already commit the planet to significant long-term sea level rise (up to two meters), making further increases from the Paris Agreement's 1.5°C target (nearly three meters) a certainty, not a possibility.
  • Aggressive emissions cuts are crucial to mitigate the severity and slow the pace of this inevitable rise, offering vital time for global adaptation efforts, despite the long-term commitment to higher seas.
