Non-CO2 emissions, including methane and nitrous oxide, are non-negligible contributors to global warming. A multimodel analysis incorporating recent advances in damage functions shows that the social cost of these greenhouse gases would increase substantially, although uncertainty remains. Nature Climate Change
