Tropospheric ozone (O<sub>3</sub>) is a strong greenhouse gas, particularly in the upper troposphere (UT). Limited observations point to a continuous increase in UT O<sub>3</sub> in recent decades, but the attribution of UT O<sub>3</sub> changes is complicated by large internal climate variability. We show that the anthropogenic signal ("fingerprint") in the patterns of UT O<sub>3</sub> increases is distinguishable from the background noise of internal variability. The time-invariant fingerprint ...[more]
