Sea Level Rise

Sea levels are on the rise due to human caused warming and they’re having devastating impacts.

On average, global sea level has risen almost 8 inches since 1901, coming from two main sources: rising ocean temperatures that cause water to expand, and melting glaciers and ice sheets which add water to the oceans.

The latest report of the Intergovernmental Panel on Climate Change concluded the oceans will continue rising in coming decades, conservatively projecting up to a 3 foot increase in global mean sea level by 2100. Other studies project an even higher sea level rise if we stay near our current emissions path for carbon pollution. In our stories, we explore how sea level rise impacts homes, livelihoods, economies, and families around the world.
