Sea level rise

Rising sea temperatures cause two problems – melting ice caps and glaciers add more water to the oceans and water expands as it warms. As sea levels rise, they cover shoreline nesting and breeding grounds for many species, such as seals, sea lions and shore birds.

This coastal squeeze is worsened by our activities to protect ourselves from sea level rise. Sea walls may temporarily protect our homes and communities from the rising waters, but they also stop sandy beaches and habitats such as mangroves from retreating up the land.
