Beskrivelse
Earth is nearly 70 percent water. Most of this water is frozen in the form of glaciers. As our planet warms, glaciers are melting faster than usual. Sea levels rise, and water washes over coastal areas. Homes are destroyed. Habitats are lost.Scientists have been following the changes in glacier ice and ocean levels. Discover what they've learned and what changes humans need to make to keep our heads above water.
