Short summary
We analyzed 26-year CH4 measurements at Mount Waliguan in the Tibetan Plateau, China. The CH4 increased ~ 133 parts per billion (ppb) with a rate of 5.1 ± 0.1 ppb yr-1 from 1994 to 2019. Major source regions were identified in northeast and southwest. The influence of human activities is more and more serious, and northern India has possibly become a stronger contributor than city regions were in the past. It has become urgent to control CH4 emissions in the Tibetan Plateau.
