Global Methane Trends and Climate Effects

Lockdowns reduced NOx, increasing methane by 20–40 million tonnes/year.
NOx decline reduced hydroxyl radicals, explaining 80–83% of methane variation.
Scientists linked methane surge to wetlands and inland water expansion.
Peng warned of ongoing NOx declines accelerating methane growth.
160+ countries under Global Methane Pledge must cut oil/gas leaks.
