Record rise of climate-warming methane in 2021: UN
International Desk
Methane concentrations in the atmosphere registered their biggest-ever increase in 2021 as all three main greenhouse gases extended their record highs, the United Nations said
Wednesday.
The UN's World Meteorological Organization recorded the biggest year-on- year jump in methane concentrations since systematic measurements began nearly 40 years ago, and said the "reason for this exceptional increase is not clear, but seems to be a result of both biological and human-induced processes".
