Even modest delay would mean missing out on significant climate benefits. Compared with the fast-action scenario, a go-slow approach that starts now but stretches out full adoption from 2030 to 2050 would mean a 5% increase in the average worldwide warming rate and an extra 0.1 C by 2050. That’s an opportunity we won’t get back,” said the lead author of the paper, Ilissa B. The results highlight the critical role of methane in any climate strategy, even as we decarbonize our energy systems. Three-quarters of those emissions are projected to come from livestock, oil and gas, and landfills, each in roughly equal measure. The new paper encompasses a broad suite of solutions which exist today that, if implemented over the next decade, could cut projected 2030 methane emissions in half, with half of that reduction achievable at no net cost. Ocko, senior climate scientist at Environmental Defense Fund. Likewise, a delayed-start strategy that squeezes reductions into a 10-year window starting in 2040 — perhaps in a rush to achieve midcentury net-zero emission goals — would result in a 20% faster warming rate and an additional 0.2 C by 2050 compared with a fast-action plan that starts now, the Environmental Defense Fund said, warning that without action, methane emissions from human activities are expected to keep rising for the rest of the century, increasing 70% or more by 2100, for a worldwide total exceeding 600 million metric tonnes per year. “Acting now and moving quickly to cut methane emissions is essential. style=”font-size:40px; line-height: 1.3em; font-weight: 800; padding:7px;”>Quick methane emissions cut could slow global climate warming by 30%

A worker turns a tap at the gas-compressor station in Mryn village, about 130 km of Kiev, Ukraine. Around 80% of no-cost actions come from the oil and gas industry. The paper estimates that fully deploying known solutions in the six sectors responsible for the lion’s share of emissions could cut the amount of methane from human sources in half by 2030, avoiding a 0.25 degree Celsius of additional global-mean warming by midcentury, and more than 0.5 C by 2100. It could mean 10 million fewer people at risk from sea level rise; half the number of people stressed for water and half the number of plant and animal species losing crucial habitat. Earlier this month, the US National Oceanic and Atmospheric Administration reported that current methane levels in the atmosphere are the highest on record. “To realize these climate benefits, decision makers need to address methane directly and not assume the problem will resolve itself as a result of policies to reduce CO2,” she added.

A rapid, full-scale effort to reduce methane emissions from the oil and gas industry, large-scale agriculture and other human sources could slow the worldwide rate of warming by as much as 30%, a newly published paper in the journal Environmental Research Letters showed on April 27. According to the Environmental Defense Fund, a half-degree C would make a critical difference in a world trying to keep warming below 2 C. Methane emissions from oil and gas cannot be ignored, a new study shows. In each of the scenarios analyzed; nearly a third of that would come from top oil and gas producers meeting their agreed upon targets to reduce upstream leakage. By reducing emissions of methane — which has more than 80 times the warming power of CO2 for the first 20 years it’s in the atmosphere — we can hit the brakes on the increasingly rapid warming responsible for stronger storms, hotter fire seasons and rapidly melting Arctic sea ice, the Environmental Defense Fund said in a press release.
