Rising sea levels mean more floods for Seacoast communities

Scientists say more can be done to mitigate effects of climate change

Rising sea levels mean more floods for Seacoast communities

Scientists say more can be done to mitigate effects of climate change

WHAT CAN BE DONE. I’VE NEVER SEEN IT THIS THIS HIGH. THIS WAS PHENOMENAL. A PERFECT STORM OF SORTS ALONG THE COAST, AN ASTRONOMICAL HIGH TIDE PAIRED WITH STORM SURGE HIT TWICE IN ONE WEEK THIS PAST JANUARY. THE BACK TO BACK STORMS BRINGING HISTORIC FLOODING TO THE COAST. I’M KIND OF SURPRISED SOME OF THE PEOPLE ARE CLEANING UP NOW BECAUSE IT COULD HAPPEN. ANOTHER 1 OR 2 TIMES THIS WINTER, THE CLEANUP LASTING WEEKS IN SOME COMMUNITIES, CREWS RACING THE CLOCK BEFORE ANOTHER STORM WOULD ARRIVE. MORE FLOODING SEEN IN FEBRUARY AND MARCH FROM STORMS, BUT LUCKILY THE SITUATION WAS LESS SEVERE, SPARING THE COAST. ANOTHER CATASTROPHE. CONSERVATIONISTS SAY THE SCIENCE SHOWS SIMILAR STORMS WILL CONTINUE TO HIT THE COASTLINE AT AN INCREASING RATE. EACH BIG STORM MAKES THE AREA LESS RESILIENT FOR THE NEXT AND WHAT THE FUTURE COULD BRING IS CONCERNING TO THE PEOPLE WHO CALL THE SEACOAST HOME. SO WHAT’S CAUSING THE CHANGE IN CLIMATE? ALONG THE COAST, SCIENTISTS SAY IT STEMS FROM A CHANGE IN SEA LEVEL. NASA EXPLAINS IT AS ICE SHEETS AND GLACIERS ARE MELTING AND SEAWATER IS WARMING, CAUSING THE WATER TO EXPAND. AND AND THEY SAY IF NOTHING IS DONE ABOUT IT, THE EAST COAST ALONE COULD SEE A CHANGE IN 10 TO 14IN ALONG ITS COASTLINE IN THE NEXT 30 YEARS. AND THEY SAY IT IS A DIRECT LINK TO HUMAN CAUSED GLOBAL WARMING. WHEN YOU HAVE THE WIND MOVING ONSHORE, THAT’S GOING TO PUSH WATER FURTHER INLAND. AND SO YOU ADD THAT ON TOP OF WATER THAT’S ALREADY MOVING INLAND DUE TO SEA LEVEL RISE, YOU’RE GOING TO HAVE MORE EXTENSIVE FLOODING. THOSE WATCHING THE OCEAN SAY IT’S IMPORTANT TO KEEP IN MIND WHAT THE STORMS CAN BRING AND TRY TO PREPARE FOR THEM. I’M OF A MIND, THOUGH, THAT IT’S IT’S A TIME TO THINK ABOUT HOW WE ADAPT. IT’S NOT GOING AWAY. IT’S ONLY GETTING WORSE YEAR AFTER YEAR. LUCIA MAURO WATCHES REPAIRS MADE TO THE SEAWALL AND QUESTIONS WHAT ELSE THE STATE CAN DO TO STRENGTHEN THE WALL. THESE ARE ALL INDEPENDENT LITTLE ROCKS AND BIG ROCKS THAT ALONE COULD BE SWEPT AWAY, BUT MORE CAN BE DONE. BUT WHAT THEY’RE ALLOWED TO DO COMES DOWN TO STATE AND FEDERAL PERMITS. YOU CAN BUILD IT BACK TO WHAT IT WAS, BUT YOU CAN’T BUILD IT BACK TO TO A DESIGN THAT’S GOING TO BE MORE RESILIENT TO WHAT YOU’RE EXPECTING IN THE FUTURE. CHANGING THOSE PERMITS IS A CONVERSATION HAPPENING AT THE STATEHOUSE. THOSE BACK TO BACK EVENTS KIND OF WERE A KIND OF A BIG WAKE UP CALL FOR EVERYBODY IN 2015. A COASTAL RISKS AND HAZARD COMMISSION FORMED, WHICH HIRED SCIENTISTS TO RESEARCH THE CHANGES AND FIND SOLUTIONS LIKE NEW LEGISLATION ON FLOODPLAIN MANAGEMENT AND HAZARD MITIGATION THAT COMMISSION DISSOLVED IN 2017. SINCE THEN, THE DEPARTMENT OF ENVIRONMENTAL SERVICES. HAS TAKEN ON THE TASKS PARTNERING WITH COASTAL COMMUNITIES. I’M NOT GOING TO SAY THERE’S NO WAY TO FIX IT, BUT I WANT TO EMPHASIZE THAT IT’S TRICKY. TRICKY. AS FOR THOSE THAT CALL THE SEACOAST HOME, THEY’RE TAKING IT. STORM BY STORM AND SAY THE FLOODING AND CHANGE IN CLIMATE WON’T HAVE THEM PACKING UP THEIR HOMES JUST YET. IT’S, UH, IT’S PART OF LIVING

Rising sea levels mean more floods for Seacoast communities

Scientists say more can be done to mitigate effects of climate change

In January, New Hampshire's Seacoast saw flooding like it has never experienced before. A month later, there was more flooding, but on a smaller scale.Scientists said the region is likely to see similar storms hitting more frequently.It was a perfect storm, of sorts, along the coast when an astronomical high tide paired with a storm surge hit twice in one week in January. The back-to-back storms brought historic flooding to the coast."I'm kind of surprised some of the people are cleaning up now, because it can happen another one or two times this winter," said Jonathan Lowell, whose father lives in Rye.The cleanup lasted weeks in some communities, with crews racing the clock before another storm would arrive.
