Earth’s lower atmosphere is rising due to climate change

Higher temperatures are forcing the upper boundary of the troposphere to expand upward

The troposphere (seen here in orange) is the lowest layer of Earth’s atmosphere and where nearly all weather occurs. Over the last 40 years, the boundary between the troposphere and the neighboring stratosphere (pink) has risen as a result of climate change.
