As Earth's climate warms, more ice is melting near the poles. And that is a huge driver of sea level rise around the globe. But some coastal communities are threatened by this more than others.
Places like the Gulf coast of Texas, for example, are feeling the impact of melting ice in West Antarctica, thousands of miles away.
NPR Climate Correspondent Rebecca Hersher traveled to Galveston, Texas, to see how that ice melt is affecting sea levels there and what experts are doing to prepare.
