1. Sea level rise: As global temperatures rise, glaciers and ice caps melt, causing sea levels to rise. This can lead to coastal erosion, flooding, and saltwater intrusion into freshwater sources, impacting ecosystems and communities along the coast.
2. Increased frequency and intensity of storms: Climate change can lead to more frequent and severe storms, such as hurricanes and cyclones, which can cause significant damage to coastal areas. Stronger storm surges and higher wind speeds can result in flooding, property damage, and loss of life.
3. Ocean acidification: Climate change is also causing the oceans to absorb more carbon dioxide, leading to ocean acidification. This can have negative impacts on marine life, including coral reefs and shellfish, which are important for coastal ecosystems and economies. Decreased biodiversity and productivity in coastal areas can have far-reaching consequences for both the environment and human populations.

1. Sea Level Rise:
- Rising sea levels due to melting glaciers and thermal expansion of ocean water erode coastlines, resulting in loss of land, inundation of low-lying areas, and increased vulnerability to storm surges.
- Coastal erosion can damage infrastructure, displace communities, and threaten ecosystems that rely on coastal habitats.
2. Increased Storm Frequency and Intensity:
- Climate change leads to warmer ocean temperatures, which fuel more frequent and intense storms, including hurricanes, cyclones, and typhoons.
- Stronger storms generate higher storm surges, which can overtop coastal defenses and cause widespread flooding, infrastructure damage, and loss of life.
- Increased storm activity also accelerates coastal erosion and exacerbates other climate change impacts.
3. Saltwater Intrusion:
- Rising sea levels and storm surges can push saltwater into coastal freshwater aquifers, contaminating drinking water sources and harming plants and wildlife that are sensitive to salinity.
- Saltwater intrusion can also disrupt coastal ecosystems, such as wetlands and estuaries, which provide valuable habitat and ecosystem services.
- In low-lying coastal areas, rising groundwater levels can cause waterlogging and damage infrastructure, such as roads and buildings.
