3 Foot sea level rise if we DO NOTHING to slow down Global Warming this coming decade.

: We Might Avert Climate Catastrophe With This One Radical Choice
But barring a major reduction in greenhouse gas emissions in the next few decades, Watson said, the world is on track to hit the IPCC’s “worst-case scenario” of a three-foot global sea-level rise by 2100.


Rising temperatures, caused by burning fossil fuels, are raising sea levels in two primary ways. Oceans, which cover 70 percent of the Earth’s surface, are absorbing about 90 percent of the increased heat, causing seawater to expand and take up more room in the ocean basins.

Sea-Level Rise Poses Hard Choice for Two Neighborhoods: Rebuild or Retreat?

The higher temperatures have also increased the melt rate of the world’s two largest ice sheets, on Greenland and West Antarctica, as well as mountain glaciers worldwide. Eventually, water from these land-based stores flows into the ocean, raising the sea level further.
“It’s like turning on another tap in the bathtub,” said Watson.
The next step in the research is to look more closely at regional rates of sea-level rise, which can vary considerably owing to local geology, ocean currents, and other factors, he said, so that nations and cities can plan effectively for an even hotter, wetter future.
“I think that our agencies, regionally, need to consider the impact of rising sea level and plan accordingly,” Watson said. “The community has the right to consistent info on these things. I think there are parts of the world where that information has been inconsistent.”
“Adaption is going to happen,” he added. “Sea level is rising, full stop. We need to be able to adapt, and the community needs better information to be able to do so.”
