About 2/3 of the federal tide stations along the East and Gulf coasts saw increased flooding over the past year.</p><p class="gnt_ar_b_p">“We’re having sunny day flooding, (with) no storm at all and you’re starting to overwhelm the defenses," Sweet said.</p><p class="gnt_ar_b_p">Every inch matters, too. A one-inch rise rise in sea level makes “a very noticeable change” when an above normal high tide pushes into low-lying areas, he said. </p><p class="gnt_ar_b_p">Compared to 2000, the East and Gulf coasts "already experience twice as many days of high tide flooding compared to the year 2000, flooding shorelines, streets, and basements and damaging critical infrastructure,” said Nicole LeBoeuf, director of NOAA's National Ocean Service. </p><p class="gnt_ar_b_p"><strong>CLIMATE POINT:</strong><a target="_blank" href="https://profile.usatoday.com/newsletters/climate-point/" rel="noopener" data-t-l=":b|e|inline click|${u}" class="gnt_ar_b_a">Subscribe to USA TODAY’s free weekly newsletter on climate change, the environment and the weather</a></p><figure class="gnt_em gnt_em_img"><img class="gnt_em_img_i" style="height:510px" data-g-r="lazy" src="https://www.gannett-cdn.com/presto/2021/10/27/NWKL/7d9182bc-e70d-4b9d-9149-cc01ad683ae1-phoMA_SC_storm9_new1103rc.jpg?width=660&height=510&fit=crop&format=pjpg&auto=webp" srcset="https://www.gannett-cdn.com/presto/2021/10/27/NWKL/7d9182bc-e70d-4b9d-9149-cc01ad683ae1-phoMA_SC_storm9_new1103rc.jpg?width=1320&height=1020&fit=crop&format=pjpg&auto=webp 2x" decoding="async" alt="A pickup truck throws a wake during high tide flooding in Scituate, Mass., in October 2021.
