Volcanic eruptions, meteorite impacts, ocean currents, and greenhouse gases have all driven changes in climate—sometimes suddenly, sometimes slowly. Scientists use ice cores, tree rings, and other natural records to uncover how these forces shaped Earth's past climate across centuries and millennia.

The melting of Arctic ice and snow decreases Earth' ability to reflect the Sun's rays, leading to further heating and melting of ice and snow. In Antarctica, the warmer climate is melting ice sheets, leading to raised sea levels, which melts ice sheets further in an amplifying loop.
