Dude, rising sea levels are totally messing up coastlines. The higher water means bigger waves hitting the land and making it fall apart faster. It's a total bummer for beaches and coastal cities.
Rising sea levels significantly exacerbate coastal erosion. Higher sea levels mean that waves and storm surges reach further inland, increasing the erosive power of the ocean. The increased water level also saturates coastal sediments, weakening their structure and making them more susceptible to erosion by wave action, currents, and wind. This effect is compounded by factors such as the loss of protective coastal vegetation, human development that disrupts natural barriers, and the changing frequency and intensity of storms driven by climate change. The combination of these factors leads to accelerated retreat of shorelines, loss of coastal habitats, damage to infrastructure, and increased risks to coastal communities. In short, higher sea levels make coastal erosion faster, more intense, and more destructive.
