Ice Core Data

Caption

Air temperature (black) and a measure of the relative abundance of ozone (red) compared to hydroperoxy radicals and other detergents. The top panel shows the full 100,000-year ice core record. As Earth warms up after the last ice age (far left in top panel), the relative abundance of ozone drops. The bottom panel is a close-up of a Dansgaard-Oeschger event, a quicker temperature swing. Here the temperature drops suddenly while the relative abundance of ozone rises.
