Nitrous oxide remains "mostly ignored," he added. "Fortunately, methane is beginning to get the attention it deserves" through initiatives like the Global Methane Pledge, a capping effort supported by the U.S. While not losing our focus on carbon dioxide, we need to pay more attention to the 'other' greenhouse gases," he added. "Concentrations of methane and nitrous oxide are not just rising, they're rising faster than ever. Rob Jackson, who heads the Global Carbon Project, suggested that the spikes in methane over the last two years were "mysterious" - either blips related to the coronavirus pandemic, which temporary dented emissions, or a sign of "a dangerous acceleration in methane emissions from wetlands and other systems we've been worrying about for decades." Over the last decade, carbon dioxide has been responsible for about four-fifths of that warming effect.Ĭlimate Nations are making new pledges to cut climate pollution. Over half of the indicators showed the world is "well off track" to cutting emissions but added that promising progress has been made.Ĭlimatologists and environmental advocates have been raising their voices for years about the impact of climate change, by pointing to vast changes in the weather in recent decades like forest fires in China and western United States, drought in the horn of Africa and unprecedented flooding in Pakistan – to name only a few.ĬO2 remains the single most important greenhouse gas generated by human activity - mainly from burning of fossil fuels and cement production - amounting to about two-thirds of the warming effect on the climate, known as radiative forcing. The report found that emissions will also increase by 10.6% by 2030 from 2010 levels, a slight decrease from the 13.7% estimates last year.Ī report published Wednesday by Climate Action Tracker who track nations' pledges to reduce warming found that of 40 indicators for reducing emissions - like weaning off coal, ramping up electric vehicles or reducing deforestation - the world wasn't on track for any of them to match the levels of emissions reductions scientists say are needed to limit warming to 1.5C. Over a 20-year time-period, a molecule of methane traps about 81 times the heat as a molecule of carbon dioxide but over a century it goes down to trapping 28 times more heat per molecule than carbon dioxide, according to the Intergovernmental Panel on Climate Change.Ĭlimate Accusations of 'greenwashing' by big oil companies are well-founded, a new study finds Methane is more potent at trapping heat than carbon dioxide, but doesn't stay in the atmosphere nearly as long as carbon dioxide and there's 200 times more carbon dioxide in the air than methane. ![]() ![]() "The continuing rise in concentrations of the main heat-trapping gases, including the record acceleration in methane levels, shows that we are heading in the wrong direction," said WMO Secretary-General Petteri Taalas. Of the three main types of heat-trapping greenhouse gases - carbon dioxide, methane and nitrous oxide - the biggest jump from 2020 to 2021 was in methane, whose concentrations in the air came in with the biggest year-on-year increase since regular measurements began four decades ago, WMO said. pledged billions to fight climate change. ![]()
