Explanation:

The tropopause is the boundary in the Earth’s atmosphere between the troposphere and the stratosphere. The tropopause is higher than the global average in warm regions (e.g., tropics) and lower in cold regions (e.g., polar regions). If the atmosphere is warming due to climate change, then we might expect the height of the tropopause to increase.
