A new study of the late Pliocene era could help scientists predict future sea level rise

November 22, 2017 — When Earth’s atmosphere warms, the vast sheets of ice over Antarctica and Greenland melt. This melting, in addition to the thermal expansion of water, leads to rising sea levels. Although it’s clear that seas are rising at an increasing rate, Continue reading How Earth’s Orbit Affected Ice Sheets Millions of Years Ago
