Total Precipitable Water and the Greenhouse Effect
Anthony Watts / 10 hours ago September 29, 2020
Global relative humidity in the upper atmosphere has generally been declining since
1970, but the there has been a recent increase since 2010 at the 300 and 400 mbar levels.
Total precipitable water is an important climate parameter as it is a measure of the total amount of water vapor in the atmosphere, which is the most important greenhouse gas.
Water vapor increases with global warming and in the climate models it amplifies the direct small warming caused by anthropogenic greenhouse gas emissions.
