● The observed atmospheric CH4 concentrations in the past decade follow the trends of the IPCC most pessimistic illustrative future GHG trajectories, which lead to global mean temperatures above 3°C by the end of this century. [...] ● The observed atmospheric CH4 concentrations in the past decade follows the trends of the most pessimistic illustrative future GHG trajectories used by the IPCC that lead to global mean temperatures above 3°C by the end of this century, underscoring the urgency of reducing anthropogenic CH4 emissions. [...] Wetland emissions have increased by 4% between the 2000s and the 2010s, mainly from the tropics and the mid-latitude regions. [...] ● In Brazil, emissions have increased due to the agriculture sector and to a lesser extent the waste sector, which is also the case for Central America and the rest of South America. [...] Implication for Reaching Net-zeros Emissions ● The observed atmospheric CH4 concentrations in the past decade follows the trends of the most pessimistic illustrative future GHG trajectories used by the IPCC that lead to global mean temperatures above 3°C by the end of this century.
