      If seas rise 20 feet over the next 2,000 years, our children and their descendants may find ways to adapt. But if seas rise 20 feet or more over the next 100 to 200 years — which is our current trajectory – the outlook is grim. In that scenario, there could be two feet of sea level rise by 2040, three feet by 2050, and much more to come.

      Two to three feet of sea level rise may not sound like much, but it will transform human societies the world over. In south Florida, where I live, residents will lose access to fresh water. Sewage treatment plants will fail, large areas will persistently flood, and Miami Beach and other barrier islands will be largely abandoned. In China, India, Egypt and other countries with major river deltas, two to three feet of sea level rise will force the evacuation of tens of millions of people and the loss of vast agricultural lands.

      Attempting to limit sea level rise therefore must become an urgent priority, including for the world leaders Joe Biden is inviting to a climate summit on Earth Day, 22 April. We must reframe how the climate emergency is understood and what it means to combat it. Certainly, it is essential to meet the Paris agreement goal of limiting temperature rise to 1.5 to 2C – but that will not be sufficient.

      The solution to rapidly rising sea levels is twofold: humans must stop putting more heat-trapping gases into the atmosphere, and we must extract much of what we’ve already put up there. Since the Industrial Revolution 250 years ago, the amount of CO2 in the atmosphere has soared due to human activities, principally the burning of carbon-based fossil fuels. To minimize future sea level rise, we need to lower that amount from today’s 417 parts per million towards the 280 ppm that prevailed before industrialization.

      will do the right thing.

      But my experience tells me they won’t. PLEASE humans prove me wrong.
