also - ‘The water is coming’: Florida Keys faces stark reality as seas rise Once people are unable to secure mortgages and insurance for soaked homes, the Keys will cease to be a livable place long before it’s fully underwater, according to Harold Wanless, a geographer at the University of Miami. “People don’t have a concept of what sea level rise will do to them. They just can’t conceive it,” he said. The pancake-flat Keys are in jeopardy from rising seas that are, as a National Oceanic and Atmospheric Administration (Noaa) scientist told the county commissioners in the Monday meeting, accelerating upwards as the vast ice sheets of Greenland and Antarctica melt away <https://www.theguardian.com/environment/2021/may/05/antarctica-ice-sheet-melting-global-heating-sea-level-rise-study>. Human-caused global heating means an extra 17in of sea level rise by 2040, according to an intermediate Noaa projection used by the county <https://southeastfloridaclimatecompact.org/wp-content/uploads/2020/04/Sea-Level-Rise-Projection-Guidance-Report_FINAL_02212020.pdf> . Compounding this problem, the islands’ porous limestone allows the rising seawater to bubble up from below, meaning it just takes high tides on sunny days to turn roads into ponds, while global heating is also spurring fiercer hurricanes <https://www.theguardian.com/environment/2020/nov/15/scientists-link-record-breaking-hurricane-season-to-climate-crisis> that can occasionally crunch into the archipelago. https://www.theguardian.com/us-news/2021/jun/24/florida-keys-climate-change-sea-level-rise
