" To which she added: "Direct measurements of methane emissions are not available for all sources of methane.
|
|
If the methane is seeping through cracks, there could be occasional large bursts of methane, Webster says.
|
|
Carbon dioxide and methane react with one other, causing the methane to eventually disappear, unless there are some types of organisms that keep pumping more methane into the atmosphere, according to the study.
|
|
And the methane trapping would also explain why scientists haven't observed much methane in Pluto's atmosphere, Nimmo said.
|
|
"We have not seen methane globally on Mars, which means methane gas is being produced somehow," Parker said.
|
|
This involves analyzing the ratio of methane and its isotopologues, which are methane molecules in which one of the constituent atoms—carbon or hydrogen—has a different number of neutrons from a 'normal' methane molecule.
|
|
At its highest level, methane from the site was double the methane emissions from the entire Los Angeles basin.
|
|
As for the methane, Curiosity's Tunable Laser Spectrometer measured the methane levels in its surrounding atmosphere over five years.

Methane was gushing from the leak, of this they could be certain, but methane was not what they smelled.
|
|
COURT PAUSES METHANE LAWSUIT: A federal court on Thursday formally paused a lawsuit over an Obama administration methane regulation.
|
|
Microbes known as methanogens consume hydrogen and carbon dioxide and produce methane; other microbes known as methanotrophs eat methane.
|
|
Abiotic methane, as it's called, doesn't involve decayed plants, animals or algae trapped in sedimentary rocks, like biotic methane.
|
|
Since methane is the primary component of natural gas, when there's a methane leak, they are losing their product.
|
|
Venting releases the powerful GHG methane, while flaring (or burning) produces CO2 emissions and also allows some methane escape.
|
|
Methane leaks: The Trump administration announced plans to weaken regulations on methane, one of the most potent greenhouse gases.
|
|
But even so, some forests in the mid-latitudes may at times emit enough methane to negate the methane-absorbing capacity of their soils, turning their ecosystems from net methane sinks to net sources, says Megonigal.
|
|
As a highly visible methane disaster, the Aliso Canyon gas leak has helped mobilize public support for tougher methane regulations.
|
|
What's more, the sporadic, intermittent nature of these apparent methane spikes suggests the methane is being released at irregular intervals.
|
|
But methane leaks can quickly cause gas to outpace the climate effects of coal, since methane is far more potent.
|
|
Opponents to efforts to curb methane waste suggest the economic impacts of implementing methane-reduction measures might be too high.
|
|
From 2015 to 2018, some 313 methane shareholder resolutions have been called on energy firms to increase their methane management.
|
|
Since the natural gas delivered to your home is 85 to 95 percent methane, natural gas leaks are predominantly methane.
|
|
On Titan, Saturn's biggest moon, a river of methane (from the upper left) branches into Ligeia Mare, a methane-rich sea.
|
|
The quantity of methane detected, along with the geology of the area, suggests the methane spike occurred within Gale Crater itself.
|
|
It can rain methane and that methane can flow into tiny lakes and large seas at the north pole of Titan.
|
|
Methane is broken down by sunlight and chemical reactions in the atmosphere; any methane there now must have been released recently.
|
|
One way to quantify the magnitude of the methane leakage is to divide the amount of methane emitted each year by the total amount of methane pumped out of the ground each year from natural gas and oil wells.
|
|
The rivers are liquid methane, for one thing, and if you're familiar with methane, you'll know that means it's really cold there.
|
|
Methane is the clear winner, easier to produce and less cost per unit than most via methane (and deep-cryo methalox specifically).
|
|
Although our energy sector emits much less methane than CO2, methane packs 84 times the global warming punch over the short term.
|
|
Like its efforts to sideline the EPA's methane restrictions, the Trump administration tried to nullify the Interior Department's methane-waste reduction rule.
|
|
"' She urged the EPA "to put in a regulatory framework that will both regulate existing methane emissions by also future methane emissions.
|
|
In fact, the methane mitigation industry has continued to grow as states and the federal government have taken action to cut methane.
|
|
That was a surprise, because sunlight and chemical reactions destroy methane; any methane there would have had to have been released recently.
|
|
Those which metabolize methane, for example, are key to the hunt for life on Mars and Enceladus where methane has been detected.
|
|
The rule on methane emissions from new oil and gas wells will not be enough to meet Mr. Obama's methane reduction targets, but the E.P.A. is also expected to move forward with additional rules governing methane leaks from existing wells.
|
|
ExoMars could also shed considerable light on the origins of Red Planet methane, said Chris Webster, who led the new Curiosity methane study.
|
|
"Agriculture represents the largest methane source in California, accounting for nearly 60 percent of methane emissions," said a draft report on the legislation.
|
|
I even started planning putting one in front of this methane camera so you could see which end the methane was coming out.
|
|
It's not just their methane-rich farts, although methane is a greenhouse gas roughly 30 times better at trapping heat than carbon dioxide.
|
|
Trump has gutted Obama's methane reduction action plan and regulators are rolling back the methane leaks rules for the oil and gas sector.
|
|
Unlike landfills, which are oxygen-poor environments that encourage the development of methane, composting is an aerobic process and does not produce methane.
|
|
The study concluded that methane from oil and gas leaks makes up about a third of total methane emitted in the United States.
|
|
HOUSE VOTES TO BLOCK EPA METHANE REG: Lawmakers approved an amendment Wednesday to block funding for a key Obama administration methane pollution rule.
|
|
Under the methane reduction plan, participating companies would deploy new technologies to detect leaks of the potent greenhouse gas, replace equipment and end certain operating practices at drilling sites known to release methane, and annually report their progress toward cutting methane emissions.
|
|
But the planet responds much more rapidly to methane, so a reduction in methane emissions now would slow the rate of global warming immediately.
|
|
When companies want to prevent emissions, perhaps when cracking down on methane leaks, they can turn to U.S. companies in the methane mitigation sector.
|
|
Oil lobbyists pressed their case that the methane rule was onerous and duplicative, since many oil-producing states already have state-level methane regulations.
|
|
Shell last month announced a plan to limit methane emissions at its assets around the world and is implementing a global methane monitoring program.
|
|
They eat carbon dioxide and release methane — and researchers think it's possible that the methane detected near Enceladus could be from tiny creatures like these.
|
|
"Rather than focus on saving money, which drove some of our early methane emission programs, we started thinking about sustainability and methane reductions," Leopold said.
|
|
Plus, lab-grown meat doesn't directly create methane emissions, while methane emissions from cows accounted for 16 percent of global greenhouse gas emissions in 2015.
|
|
The bulk of this ancient methane gets into the atmosphere during the production and transport of natural gas, of which methane is the principal component.
|
|
Instead, it's recommended that farmers cut down on other sources of methane, like fertilizers, while also improving their cows' diets to help curb methane emissions.
|
|
GAO HITS INTERIOR ON METHANE ACCOUNTING: The Government Accountability Office (GAO) wants the Interior Department to do more to measure methane emissions on federal land.
|
|
Only 10 percent of local methane sources are contributing half of the emissions in a methane plume near the Four Corners, federal scientists announced today.
|
|
Meanwhile, EPA's own highly questionable methane emissions estimates show that marginal wells account for less than 12 percent of all oil and gas methane emissions.
|
|
Since methane is the primary component of natural gas, wasted methane means wasted energy and lost revenue for both energy companies and the American taxpayer.
|
|
METHANE VOTE COMING TOMORROW: The Senate is due to consider a Congressional Review Act (CRA) resolution on Wednesday undoing an Obama administration methane waste rule.
|
|
The leading theory was that fluctuations in Earth's orbit around the sun melted a type of frozen methane just beneath the seabed called methane clathrates.
|
|

|
|
They placed a film of methane ice—methane is an abundant molecule in space—in a vacuum chamber and then bombarded it with low-energy electrons.
|
|
Energy companies, however can mix ethane, which is usually more valuable than methane, with methane if there is not enough liquids pipeline capacity to ship ethane.
|
|
State regulators want more farmers to reduce emissions with methane digesters, which capture methane from manure in large storage tanks and convert the gas into electricity.
|
|
SENATE KILLS METHANE REPEAL: A GOP resolution to repeal the Obama administration's methane rule for public lands was torpedoed Wednesday by a surprise decision from Sen.
|
|
Scientists also need to better understand methane sinks, the processes that break down methane in the soil and the atmosphere, to develop a more accurate budget.
|
|
POWER PLANTS' METHANE RELEASES UNDERESTIMATED: A study published Tuesday says that the methane emissions from natural gas-powered fire plants are much higher than previously estimated.
|
|
Although methane from fires has dropped off, the study suggests that just the opposite is occurring for methane released from swamps and human fossil fuel activity.
|
|
The regulation, part of a federal methane reduction strategy that Trump has also repealed, was designed to cut 520,000 short tons of methane pollution by 2025.
|
|
Any methane there must have been created recently, and the two possibilities for creating methane are microbes and a geological process requiring heat and liquid water.
|
|
Add to that a rider to block EPA from enforcing its Methane Pollution Standard (MPS) on the oil and gas industry, the largest dischargers of methane.
|
|
The EPA has a responsibility to listen to oil and gas professionals, and experts in the methane mitigation industry, and must leave federal methane rules intact.
|
|
But the latest EPA data show that natural gas systems methane emissions have declined 3.5 percent since 85033, while overall methane emissions have declined as well.
|
|
We need monitoring, testing and studies that explain the environmental and human health impacts of exposure to methane and other pollutants released alongside methane during development.
|
|
"Once the methane is in the air, it will be there for 10-plus years until it is chemically converted to carbon dioxide and methane," said Howarth.
|
|
GOP MAJORITY LOOMS OVER OBAMA METHANE RULE: The Interior Department on Tuesday issued its long-awaited rule to slash methane emissions at drilling sites on federal land.
|
|
There is a seasonal variation to the methane that repeats, which means the methane is being released from the Martian surface or from reservoirs beneath the surface.
|
|
Oil and gas companies call the rules unnecessary and costly, maintaining that they already have an incentive to stop and prevent methane leaks: Methane can be sold.
|
|
GREENS WANT METHANE RULE ENFORCED: Environmental groups are asking a federal court to reinstate the Environmental Protection Agency's (EPA) methane rule for oil and natural gas companies.
|
|
The companies agreed to take steps to reduce methane emissions, work with institutions and governments to write new methane regulations, improve emissions reporting data and increase transparency.
|
|
BP recently set a methane target for the first time, and ExxonMobil said it would cut methane emissions and has come out in favor of federal regulation.
|
|
Methane emissions As part of its larger strategy to combat climate change, the Obama administration approved two rules to minimize emissions of methane, a potent greenhouse gas.
|
|
Other human-induced emissions of methane come from changes to land use and the effects of climate change on wetlands, which are major producers of global methane.
|
|
The methane disappeared so quickly, and the usual levels are so low, that scientists are now trying to explain how methane could have been destroyed so quickly.
|
|
Methane can be created by geological interactions between rock, water and heat, or it could be a product of microbes that release methane as a waste product.
|
|
Reducing methane is important to slowing global warming because methane is 80 times more potent than carbon dioxide, although it doesn't last as long in the atmosphere.
|
|
But, while some companies have been proactive in working to reduce methane waste, methane mitigation companies I represent have seen that voluntary partnerships remain the exception, not the rule, and are simply not enough to address the vast amount of methane waste from the oil and gas industry.
|
|
Though methane leaks have been a fixture of drilling for some time (about 31% of methane emissions come from natural gas and petroleum systems, according to the EPA), over the past decade, fracking has prompted a "massive" increase in methane in the atmosphere, according to the European Geosciences Union.
|
|
To separate methane emissions from natural gas from other sources such as landfills, the researchers tracked ethane, which is found in natural gas but not other methane sources.
|
|
Thus, instead of clamping down on landfills because of the methane they produce, or incinerators for fear of dioxins, governments should tackle methane and dioxins across the board.
|
|
All told, the oil and gas industry leak millions of tons of methane per year, according to Mark Brownstein, a methane policy expert with the Environmental Defense Fund.
|
|
Ruminants—cows, sheep, and goats—release about 100 million tons of methane each year by farting, burping, and shitting, accounting for roughly 20 percent of global methane emissions.
|
|
We are trying to be leaders on methane emissions, we've set targets of 0.2% methane reduction levels, not reductions, levels for the company, reducing our greenhouse gas emissions.
|
|
Carbon monoxide is co-emitted with methane from wildfires and biomass burning, and ethane is a hydrocarbon that's often co-emitted with methane from oil and gas production.
|
|
The new methane rules are being watched closely in Canada, where Prime Minister Justin Trudeau has pledged to work with Mr. Obama on a joint methane reduction strategy.
|
|
As political support grows for federal oil and gas methane safeguards, so does the pressure for the Trump administration and EPA to reconsider their approach to methane pollution.
|
|
"The controls to reduce VOCs emissions also reduce methane at the same time, so separate methane limitations for that segment of the industry are redundant," the EPA said.
|
|
Pluto has an icy shell, dunes made of solid methane ice, and mountain peaks covered in methane snow (but the snow is red instead of a fluffy white).
|
|
It's part of an Obama administration strategy to reduce methane emissions at oil and gas facilities, something drillers have resisted, citing their own voluntary work on methane reduction.
|
|
The extent to which these emissions cause rising methane levels has long been debated among scientists — livestock, landfills and other sources linked to human activity also emit methane.
|
|
DEMS PUSH FEDS ON METHANE LEAK: Three top Energy and Commerce Committee Democrats are asking federal officials to detail how they're monitoring a major methane leak in California.
|
|

|
|
Methane losses from the production, processing and transmission of oil and natural gas makes the industry the No. 85033 source of methane emissions in the U.S. and globally.
|
|
In the wake of increased scrutiny over methane leaks, Trudeau and Obama committed to cut methane emissions by 40 to 45 percent below 2012 levels by 2025, and to begin more thorough regulation of emissions from existing oil and gas operations, which account for 29 percent of U.S. methane emissions.
|
|
The regulator last year said it would try to reduce emissions of methane, which is far more damaging to the environment than carbon dioxide, by requiring new oil and gas processing and transmission facilities to find and repair methane leaks and for producers to capture or limit methane from shale wells.
|
|
Methane on Mars is the subject of a decades-old debate with exceptionally high stakes: if there's methane on Mars, it could be a sign of life there, too.
|
|
But methane-rich Siberian air (see map of average atmospheric methane levels in January 2145, above) shows no sign of rising any faster than the rest of the world.
|
|
New research suggests that methane leaks in the Arctic may actually slow the effects of global warming, challenging conventional understanding of how greenhouse gases (like methane) impact climate change.
|
|
By analyzing the carbon isotopes of the methane found in the atmosphere, a variety of recent studies have tried to deduce the different sources of the recent methane spike.
|
|
Oil and gas companies can use infrared cameras to track methane leaks and plug them — or capture excess methane and sell it rather than venting it into the air.
|
|
This view comes amid growing criticism about emissions of methane, a potent greenhouse gas that's the main component of gas, and the Trump administration's regulatory rollback of methane rules.
|
|
Challenging EPA over methane emissions California filed suit against the EPA in 2018 over the agency's supposed failure to reduce methane emissions from oil and natural gas mining operations.
|
|
Challenging EPA over not implementing methane rule for landfills The state sued last year to force the EPA to enforce a 2016 a rule governing methane emissions from landfills.
|
|
Attempting to suspend an Obama-era methane rule Under Pruitt, the EPA tried to suspend an Obama-era rule to restrict methane emissions from new oil and gas wells.
|
|
Scientists already knew that Titan has gone through periods of cooling and warming, as sunlight depleted the heat-trapping methane in its atmosphere, then methane later built up again.
|
|
Outside groups have waged a lobbying war over the methane rule, an Obama administration effort to limit venting and flaring of methane pollution from drilling sites on federal land.
|
|
Titan has a methane cycle similar to Earth's water cycle—except with, you know, methane—so that should make for some interesting chemical signatures of life, should there be any.
|
|
Measurements of methane, molecular hydrogen and carbon dioxide in the global ocean show that the ocean has the chemical energy necessary for microbes to produce methane -- if there are microbes.
|
|
They have opposed efforts to restrict methane emissions, arguing that federal rules are duplicative in light of state standards, and that the industry is good at self-regulating methane leaks.
|
|
TRUMP SET TO WEAKEN METHANE RULE: The Trump administration is poised to roll back existing regulations on methane gas as early as this week, The New York Times reported Monday.
|
|
Several are from Colorado, which has instituted its own state controls on methane emissions, and New Mexico, which has some of the most concentrated levels of methane in the nation.
|
|
Next month, EPA will start a formal process to require companies operating existing methane emissions sources to provide information to assist in development of comprehensive standards to decrease methane emissions.
|
|
California's pioneering law SB 1383 requires that the state reduce methane pollution from organic waste 40 percent by 2030; it does not require that it capture 40 percent of methane.
|
|
First, it captures all methane emissions, rather than just the emissions tied to natural gas operations – including the methane from landfills, cows and even the leaves rotting in your backyard.
|
|
The Environmental Defense Fund estimates over 92,000 metric tons of methane so far, which represents 35 percent of the total annual methane emissions from the state's oil and gas sector.
|
|
The Environmental Defense Fund estimates over 92,000 metric tons of methane so far, which represents 453 percent of the total annual methane emissions from the state's oil and gas sector.
|
|
The findings are presented by the newly-released Global Methane Budget published Monday -- part of an effort by 100 international scientists to understand just how much methane is rising, and why.
|
|
In previous trips, Semiletov said he found methane at 3, 4 or 5 parts per million at these sites, well above the average atmospheric methane concentration of 1.7 parts per million.
|
|
Moreover, Mars is known to contain copious amounts of methane at the surface, pointing to the possible presence of methane-gobbling microorganisms beneath the Martian surface, according to the new paper.
|
|
The issue of methane waste on public lands made national headlines when NASA discovered a methane cloud hovering overhead the San Juan Basin in Four Corners region of northwest New Mexico.
|
|
The EPA's rules are part of a suite of methane efforts from the Obama administration, including rules specifically for wells in federal land and voluntary programs to cut methane in agriculture.
|
|
In addition to support for strong federal methane rules from Shell, BP, ExxonMobil and Equinor, a bill to block and reverse the administration's methane rollbacks recently was introduced in the House.
|
|
TRUMP TARGETS OBAMA METHANE RULE: The Trump administration announced a plan Tuesday to roll back a major Environmental Protection Agency (EPA) rule that restricts emissions of methane, a potent greenhouse gas.
|
|
Editing a letter to the EPA on methane emissions The offices collaborated on pushback against seven states that announced plans to sue the EPA for lack of methane regulation in 2012.
|
|
Methane does seem to waft episodically into the atmosphere, she said, pointing out that both Curiosity and Mars Express observed methane in the same place at the same time in 2013.
|
|
It is duplicative of state and Environmental Protection Agency efforts to reduce methane emissions from oil and gas sites and ignores that methane emissions have steadily dropped due to industry innovation.
|
|
The work will focus on what is called methane pyrolysis, a method of breaking down the methane in natural gas into a gaseous hydrogen inside a vacuum and obtaining solid carbon.
|
|
A combination of carbon dioxide and methane (like in Earth's atmosphere) can be even more telling, since carbon dioxide and methane would normally react with each other to produce new compounds.
|
|
For example, a methane survey in California led by NASA's Jet Propulsion Laboratory from 2015 through 2017 found that 80 percent of methane emissions came from 25 percent of its sources.
|
|
Obama's updates to the EPA's New Source Performance Standards envisioned preventing emissions of 300,000 short tons of methane in 2020, rising to preventing 510,000 short tons of methane emissions in 2025.
|
|
Methane, a primary component of natural gas, has a global warming potential 20 times that of CO2, but methane molecules have a much shorter lifespan in the atmosphere -- about 10 years.
|
|
On methane-rich planets, as the researchers argued in 2014, photosynthesizers might harvest carbon from methane (CH4) rather than CO2 and spew hydrogen rather than oxygen, leading to an abundance of ammonia.
|
|
Though oil and gas drilling and exploration release the majority of methane pollution in this country, until recently federal methane regulation had mostly been either voluntary or tied to other air standards.
|
|
"We have numerically modelled the evolution of methane hydrates through the last Ice Age up until today, and the methane hydrates became unstable at the time estimated for crater formation," she said.
|
|
The province's Climate Leadership Plan also tackles methane emissions with new regulatory standards that are expected to reduce methane emissions by 45 percent by 2025—an annual reduction of 1 million tonnes.
|
|
An article on April 3 about a methane leak in Los Angeles misstated the amount by which the Aliso Canyon leak increased the rate of methane emissions in the Los Angeles Basin.
|
|
While methane only makes up about 10 percent of greenhouse gases, according to the EPA, the methane rule was key to the Obama administration's push to lessen the impacts of climate change.
|
|
Measurements of methane, molecular hydrogen and carbon dioxide in the global ocean show that the ocean has the chemical energy necessary for microbes to produce methane -- if there are microbes, Waite said.
|
|
While methane only makes up about 2628 percent of greenhouse gases, according to the EPA, the methane rule was key to the Obama administration's push to lessen the impacts of climate change.
|
|
While methane makes up only about 2202 percent of greenhouse gases, according to the EPA, both methane rules were key to the Obama administration's push to lessen the impacts of climate change.
|
|
Other Obama-era regulations are harder on natural gas — both the Environmental Protection Agency and Bureau of Land Management's methane rules targeted oil and gas production, leaving methane-venting coal mines alone.
|
|
Why methane reduction is important: A study by the American Geophysical Union released last week warned that methane reductions from the oil and gas industry were "essential" to meeting global climate goals.
|
|
Generally speaking, fossil fuel production produces heavier methane and biogenic sources produce lighter methane, so researchers have taken the trend as an indication that the recent spike is mostly biogenic in origin.
|
|
Mexico will also join the U.S. and Canadian push to reduce methane emissions by at least 40 percent by 2025, with all three countries pledging federal methane regulations to reach the goal.
|
|
Methane leakage erodes the climate benefit of switching to natural gas in all scenarios, but this impact is largest in the near-term due to the shorter lifespan of methane than CO2.
|
|
The U.S. Environmental Protection Agency has designated One Future to lead the industry's attempt to reduce methane emissions from gas production, processing, transmission and distribution in the agency's expanded Methane Challenge program.
|
|
The EPA is finalizing a rule that would require new oil and gas processing and transmission facilities to find and repair methane leaks, and to capture or limit methane from shale production.
|
|
The good news is that scientists and companies are slowly developing techniques for controlling methane: infrared cameras to detect (and help plug) methane leaks from natural gas pipelines; new types of feed that cause cows to belch less (no, really); even new genetically engineered rice varieties that don't transfer as much methane from flooded paddies into the atmosphere.
|
|
Rice production and livestock both emit methane into the atmosphere, but Pep Canadell, another co-author of the editorial, says that there are challenges in curtailing the spread of methane from either source.
|
|
In fact, many scientists worry that by warming the oceans, climate change is speeding up the very processes that produce methane, in addition to melting icy methane hydrates that accumulate on the seafloor.
|
|
Those who see fracking as an ominous practice, one with environmental consequences and dangers that go beyond methane emissions, won't stop organizing or slow their criticisms because of new regulations on methane emissions.
|
|
The EPA last year proposed strict limits on methane leaks from oil and gas drilling as part of the administration's strategy to slash methane emissions by up to 85033 percent from 2012 levels.
|
|
Loosening restrictions on methane emissions Last year, Trump's EPA announced that it would no longer require oil and gas companies to install monitors that detect methane leaks from new wells, tanks and pipelines.
|
|
On Earth, microbial life is a key source of methane.
|
|
However, unlike carbon dioxide, there is a market for methane.
|
|
Pluto's atmosphere is rich in nitrogen and low on methane.
|
|
But methane is many times more potent during that time.
|
|
Food waste accounts for a significant portion of methane emissions.
|
|
Methane puzzle The ESA probe aims to find out more.
|
|
The spacecraft found traces of methane gas in that material.
|
|
The product, or output from consuming these compounds, is methane.
|
|
Scientists recorded highs of methane and nitrous oxide as well.
|
|
But this fossil methane is only 20% of the total.
|
|
More accurate tallies of individual methane sources are needed, too.
|
|
Methane is 25 times worse for climate change than CO2.
|
|
Finally, that methane fuel could be harvested on Mars itself.
|
|
Yes, methane, the primary component in natural gas on Earth.
|
|
The switch to methane produces a more efficient engine, basically.
|
|
Methane shows up like fog clouds in the infrared spectrum.
|
|
The methane rule will also end up hurting the environment.
|
|
The province will also invest more in coalbed methane exploration.
|
|
Good step, but why don't they measure methane from Ag?
|
|
The rover has also detected methane in the Martian atmosphere.
|
|
For natural gas, it is methane, the fuel's main component.
|
|
But the problem of methane leaks should not be downplayed.
|
|
But it's about 0.002 percent of the global methane budget.
|
|
Broadly speaking, there are two possible sources for Martian methane.
|
|
Methane from both sources will mix eventually into the atmosphere.
|
|
Her reasoning for this change of position on methane rules?
|
|
Common sources of methane emissions include wetlands and livestock operations.
|

So for ten years, there's been a bonafide methane mystery.
|
|
Methane is itself an extremely stable form of stored energy.
|
|
Methane accounts for 11 percent of total US climate pollution.
|
|
Animal manure and rice paddies are also big methane sources.
|
|
Carbon and methane aren't the only substances wildfires shake loose.
|
|
Why the methane is there is still a bewildering mystery.
|
|
But it has also lobbied to weaken U.S. methane regulations.
|
|
Thus any methane detected now must have been released recently.
|
|
Industry accounts for about a third of domestic methane emissions.
|
|
Perdue burns the methane to make electricity for its plants.
|
|
Why it matters: Methane is a very potent greenhouse gas.
|
|
Andrew Aubrey knows a lot about how to find methane.
|
