VIDEO: Mitigating climate disruption in time: A self-consistent approach for avoiding both near-term and long-term global warming

Dr Gabrielle Dreyfus and Durwood Zaelke of Institute for Governance and Sustainable Development (IGSD) present the concepts and findings discussed in the paper “Mitigating climate disruption in time: A self-consistent approach for avoiding both near-term and long-term global warming”. The case is made that preventing the worst of climate disruption has two aspects: 1) decarbonization, the process of eliminating fossil fuels and other sources of CO2; and 2) reduction in short-lived climate pollutant (SLCPs) such as methane, NOx, black carbon and hydrofluorocarbons. Watch and find out why both are important ...

An Earth Day Technology Worth Investing In

Global emissions of methane are skyrocketing. But if we act now, we can start getting it out of the atmosphere. [Originally published on] This year’s Earth Day comes on the heels of some alarming climate news. But if we act now, we can make a huge difference. This April, scientists observed a record annual increase in methane levels in the atmosphere for the second year in a row. It’s the largest increase since record-keeping began. Methane is a greenhouse gas that’s over 80 times more potent than carbon dioxide. It’s a major contributor to global warming. Man-made sources of ...

In Wired: It Might Be Time to Take Methane Removal Seriously

Jackson and other scientists suggest it's time to think about removing methane from the atmosphere, in addition to cutting back on new emissions.... [They] have argued that the heating effects of methane are chronically undervalued, because current climate policies emphasize long-term temperature goals that extend far beyond the lifetime of a methane molecule. The value of reducing methane levels spikes when you factor in the benefits of preventing warming now.... Methane is a single carbon atom surrounded on four sides by hydrogen, and these bonds are broken apart by a process called oxidation—it involves oxygen atoms plus some goading by energy ...

In ScienceDirect: Perspectives on removal of atmospheric methane

This article reviews proposed methods for atmospheric methane removal at a climatically significant scale. These methods include enhancement of natural hydroxyl and chlorine sinks, photocatalysis in solar updraft towers, zeolite catalyst in direct air capture devices, and methanotrophic bacteria. Though these are still at an early stage of development, a comparison is provided with some carbon dioxide removal methods in terms of expected costs. The cheapest method is potentially enhancement of the chlorine natural sink, costing as little as $1.6 per ton CO2-eq. Read the full article in ScienceDirect ...

"If new methods for methane removal can be proven and scaled up, “it would be extremely powerful,” says Lena Höglund-Isaksson, a senior research scholar at the International Institute for Applied Systems Analysis. If the concentration of methane in the atmosphere could be cut in half, restoring pre-industrial levels, it could help cool the planet by around half a degree Celsius—a huge amount that might make it possible to keep global warming below 1.5 degrees by the middle of the century, if CO2 emissions also drop."

In The Washington Post: Biden wants to cut methane emissions. But we need to get it out of the air, too.

This week at the COP, the Biden administration announced a broad methane initiative, which includes new draft Environmental Protection Agency regulations tightening up methane leaks in the oil and gas industry and additional actions by agencies across the federal government. These developments should make a real difference. But even with a greater focus on emissions reductions, some methane emissions, particularly in food production, will be difficult to eliminate. Natural sources of methane could even increase in the coming decades as wetlands warm and Arctic permafrost thaws. So in addition to cutting methane emissions, we need ways to remove methane from ...

In the journal Science: To slow global warming, some researchers want to pull methane out of the air

Methane, long eclipsed by carbon dioxide (CO2) as a villain in climate change, is having its moment in the spotlight. The United Nations climate summit opened here this week with faltering global commitments to reducing CO2, but more than 100 nations have agreed to cut their methane emissions by one-third by 2030. Officials hope cracking down on the potent greenhouse gas will help limit global warming to a 1.5°C rise, the goal established by the 2015 Paris agreement. Now, some researchers say they want to not only put less methane into the atmosphere, but also actively pull it out. Read ...

In Chemical & Engineering News: Methane cuts could slow extreme climate change

Methane has been somewhat neglected in discussions about climate change, but it’s been getting more attention lately, including in the most recent scientific report from the Intergovernmental Panel on Climate Change (IPCC). “As hard as reducing CO2 is, we’re not going to meet our temperature targets by tackling CO2 alone,” says Rob Jackson, an earth system scientist at Stanford University and chair of the Global Carbon Project. “We have to tackle methane.” Read the full article in Chemical & Engineering News.

In The Hill: Focus on methane is timely and appropriate

Policymakers have gotten the memo about methane’s outsized role in climate change, and thankfully, they’re swinging into action to reduce methane pollution, including a new U.S.-EU pledge to cut methane emissions 30 percent. But since the promised cuts can’t cover all methane sources, there is uncertainty about how far and how fast they will lower atmospheric methane levels. The best strategy is a two-track approach: aggressively reducing emissions wherever we can, and where we can’t, developing ways to remove methane from the atmosphere.

In The Royal Society Publishing: Methane removal and the proportional reductions in surface temperature and ozone

Abstract Mitigating climate change requires a diverse portfolio of technologies and approaches, including negative emissions or removal of greenhouse gases. Previous literature focuses primarily on carbon dioxide removal, but methane removal may be an important complement to future efforts. Methane removal has at least two key benefits: reducing temperature more rapidly than carbon dioxide removal and improving air quality by reducing surface ozone concentration. While some removal technologies are being developed, modelling of their impacts is limited. Here, we conduct the first simulations using a methane emissions-driven Earth System Model to quantify the climate and air quality co-benefits of methane ...

In The Royal Society Publishing: Atmospheric methane removal: a research agenda

Abstract Atmospheric methane removal (e.g. in situ methane oxidation to carbon dioxide) may be needed to offset continued methane release and limit the global warming contribution of this potent greenhouse gas. Because mitigating most anthropogenic emissions of methane is uncertain this century, and sudden methane releases from the Arctic or elsewhere cannot be excluded, technologies for methane removal or oxidation may be required. Carbon dioxide removal has an increasingly well-established research agenda and technological foundation. No similar framework exists for methane removal. We believe that a research agenda for negative methane emissions—‘removal' or atmospheric methane oxidation—is needed. We outline some ...
