New York City has two big challenges: sinking buildings and rising sea levels. Some tall buildings make the ground sink, and the sea is rising faster there than in other places. By 2050, the sea might rise between 8 and 30 inches, causing big problems. Climate change also brings heavier rain and storms. To solve these problems, we need to protect buildings near the water from flooding. Experts found that certain areas in New York City sink faster, maybe because of how they were built. Lower Manhattan, Brooklyn, Queens, and the north end of Staten Island are some of those areas.

Scientists are still studying why this happens. Other cities around the world face similar problems, like Jakarta, which had to move its capital because the ground was sinking too fast. Understanding these changes is important to find ways to deal with them and protect cities from rising sea levels.
