Why did #methane surge in 2020 ?

Our article just published @Nature shows that the high growth rate of CH4 in 2020 is explained half by decreased OH removal & half by more wetland emissions @ShushiPeng @CEA_Officiel @gcarbonproject @IPSL_outreach … 🧶… Image
We expected in 2020 less anthropogenic emissions from #COVID but in fact the #CH4 growth rate was record high at 15.1 ppt y-1 (@NOAA data ) Image
The #CH4 growth rate results from an imbalance between emissions ( natural and anthropogenic ) and the OH sink in the atmosphere @gcarbonproject Image

While diplomats in Egypt were negotiating the #COP27 agreement last month to help poor nations cope with the crippling impact of a warmer planet, one of the biggest US climate disasters in recent years was unfolding in a rural corner of #Pennsylvania: 1/11…

A leak from a 1 5/8-inch vent on a natural gas storage well operated by @EquitransMid was discovered on Nov. 6 and lasted for 13 days, during which more than 1 billion cubic feet of the fossil fuel escaped. 2/11
The primary component of natural gas is #methane, which has a devastating impact on the climate if released directly into the atmosphere where it has more than 80 times the warming power of carbon dioxide in its first two decades. 3/11

🧵All COPs are disappointing; they never do enough to slow warming to keep the planet and its people safe. Year after year, COPs show the power of the fossil fuel industry and its cruel indifference to the planetary suffering it is causing & the climate chaos it will soon unleash
But if you look hard enough, it’s possible to see several positive outcomes from #COP27 . This COP made important progress on several key fronts, inc holding the line on 1.5°C & noting tipping points incl in the cryosphere.…
#COP27 also made progress on #methane, mostly outside the COP: 150 countries plus the EU are now part of the #GlobalMethanePledge, including vulnerable islands & other states

Let's get into one of the most far reaching pieces of regulatory action from @EPA. 3 areas stand out:

1) Comprehensive - every possible #methane source is covered, no loopholes
2) Embraces tech innovation even under uncertainty
3) Acknowledges & corrects for EPA blind spots
All O&G #methane sources are covered, including low producing sites & often owned by small, independent companies. Research has show these type of sites can be a significant source of emission, and until recently, was exempted from all regs.

Not anymore.…
Changing definitions: This may be in the weeds but a huge shift in accounting for #methane. Policy stringency now depends on physical number of equipment on facilities and not arbitrary baseline emissions.

This significantly improves policy effectiveness & compliance monitoring.

Last month, @WMO reported that methane emissions are rising faster than ever.

Today, we explore how governments fail to tackle methane emissions from animal agriculture—and why we need to slash methane emissions now to tackle #GlobalWarming and ensure a livable future. 1/13 Image
2020 and 2021 saw the largest increases in methane emissions since records began, according to @WMO.

Their data indicates that biological sources, such as agriculture, are responsible, rather than #methane from gas leaks. @ConservationOrg reports. 2/13…
Animal agriculture contributes to global warming through GHG emissions, including methane and nitrous oxide.

Millions of ruminant animals raised for food globally, such as cows and sheep, emit #methane through a process called enteric fermentation. 3/13…

‼️SUBMISSIONS DUE BY 5PM - tips in 🧵

The NSW EPA has the power to make reducing #coal mine #methane a priority in its new climate plan. Even a super short submission makes a difference:

#GlobalMethanePledge #MoveBeyondCoal
Ask the EPA to use its authority to take quick action to:

1. Reduce NSW coal mine methane at least 75% by 2030, the amount the IEA says is required for Net Zero by 2050.

2. Recommend no new coal mines or expansions be approved.
3. Require coal companies to cut their methane emissions using all available technology.

4. Require companies to actually measure and transparently report their emissions.

🗓️ The deadline for @Europarl_EN amendments to the @EU_Commission #methane regulation proposal is this Wednesday!🗓️

MEPs have outspokenly supported strong methane action, and policymakers can help strengthen the proposal. Some of the main amendments we'll be looking for 👇
1. Step up methane monitoring + reporting.
Europe must monitor methane emissions based on direct measurement and in line with OGMP 2.0 standards.

Innovations like @MethaneSAT will support these efforts and boost climate transparency and accountability.
2. Plug methane leaks.

Many methane emissions from oil and gas stem from persistent leaks. To #CutMethaneEU, Europe needs to enforce leak detection and repair requirements in line with best international practice.

"Our imagination does´nt has any scenario left in which this could not be a targeted attack" @Tagesspiegel quotes a person involved in the assessment of the German gov regarding the incidents at the #Nordstream #pipelines in the #Balticsea

A first thread ⚠️ #Druckabfall
Yesterday, authorities acknowledged a decrease in pressure in both pipelines; first in NS2, later also in NS1. The 3(!) leakages are to be found in the East of Danish Bornholm (NS2), and also two leaks in the Northeast of the Island (NS1)
Two leaks are within the Danish Exclusive Economic Zone (EEZ), one is in the Swedish EEZ. Sea depth in the region is around 50m.

1/ What the average observer of the #Ethereum merge to Proof of Stake needs to know when considering all the headlines & fanfare about “reduced energy consumption” and then asking “why doesn’t #Bitcoin do this too?”, is that #ETH and $BTC are fundamentally different assets/tools.
2/ #Bitcoin and #Ethereum are not like “Coca Cola and Pepsi”. They are not interchangeable brands of the same type. They are designed and have evolved to achieve very different things. Their context and needs are different, and how we asses them needs to be guided by this.
3/ #Ethereum has evolved and aspires to be a base technological layer for development of creative assets like NFTs, and to enable venture capitalists and others a way to financialize, exchange, and bet on these within the structures of our current monetary & financial systems.

Exemple aux 🇳🇱 où notre challenge est de faire accepter le #charbon en dénigrant le #gaz ⤵️
C'est notre agence qui s'était occupée de faire passer l'idée depuis 20 ans que le gaz est une merveilleuse énergie de #transition🌻 de fait on sait parfaitement détricoter notre propre argumentaire pour désormais pousser le charbon. Le soutien des partis écolos est sans faille🤝
1⃣ Dire que ça nous fera gagner de l'argent

--Rallumer les centrales à charbon permet d'économiser de l'argent, les installations étant déjà présentes, argent économisé qu'on pourra ensuite investir dans les #EnR--

Big #Oil v the World
The recent spell of extreme heat has reminded us of the challenges of #climatechange. As the evidence that it’s a reality grows, a timely three-part documentary from the BBC points a finger of blame at the culprits.
Central Bylines…
/2 Part one – Denial – takes us from the early 1980s to the late 1990s and reveals that Exxon, a major oil company, had scientists modelling the impact of carbon dioxide (CO2)in the atmosphere and drawing stark conclusions about what would happen if levels continued to increase.
/3 This research was all but buried.

Part two – Doubt – shows how the industry used paid lobbyists to influence both public and political opinion against science.

Here are #methane details:

- $850M to EPA for methane monitoring/mitigation
- Fee at $900/t in 2024 going up to $1500/t in 2026.
- EPA methane regs compliant facilities exempt if equivalence can be demonstrated
- EPA required to update inventory estimates in 2 years
Here's the thing:

$900/t CH4 in 2024 is ~$17/mcf of gas, roughly 2x current Henry Hub price. That's a strong incentive for #methane reductions.

$1500/t CH4 is ~$29/mcf. These high prices will incentivize operational changes (e.g., switch gas engines to electric drive motors).
Fees applied to emissions intensities over:
- Production: 0.2% of gas, 10 mt/mbbl of oil
- Transmission: 0.11%
- LNG & other facilities: 0.05%

Only facilities reporting to EPA (>25000 mt CO2e/year emissions) will be subject to #methane fees.

Really excited to share our last paper about the importance of #groundwater discharge as driver of #methane emissions from #Arctic lakes published in @NatureComms !…
In this paper we sampled ten different lakes in the Abisko region to evaluate spatial and temporal patterns of groundwater discharge and implications in lake CH4 emissions (1/6) Image
A 222Rn mass balance revealed that groundwater discharge was an important water source for the lakes, with inflows comparable to those from inlet streams (2/6). Image

Scientists found massive #methane leak at the Ku-Maloob-Zaap oil field cluster that state oil company @Pemex operates in the Gulf of Mexico oil field 🧵…
Led by @itziraloi, the scientists calculated about 4,000 tons of methane were released during just 17 days in December. @Pemex emitted a quantity of methane equivalent to 3.37 million tons of carbon dioxide or 3% of the country's annual CO2 emissions.
The leak is likely a result of "abnormal process conditions at the site" like malfunctions or equipment, they said. To minimize its harmful impact, oil and gas companies aim to flare the methane component of natural gas when comes to the surface as a byproduct of oil production.

Just in: our report on #bitcoinmining & #climatechange

Full report:…

1. Using #BTC mining to combust leaking methane can eliminate 5.32% of all global CO2-eq emissions...

#ESG #sustainability #methane #UNEP #IPCC #CCAC #climatechange Image

2. By aggressively targeting leaked methane, Bitcoin mining has the potential to avoid 0.15% of warming by 2045, potentially earlier.

#BitcoinIsGreen #environment Image

3. No other existing technology is currently equipped to achieve this feat at this pace.

In short: Reducing methane emissions is the strongest lever we have to slow climate change. #Bitcoin mining is the fastest, most reliable hand we have upon that lever. Image

🚨New Paper Alert🚨A common justification for LNG expansion is potential for emissions reductions through coal to gas switching in power sector.

Is this claim true? @LydiaYang21, @S_HastingsSimon & I explore.

Short answer: Yes & No. 1/…
Near-term (<~2035)
LNG expansion aligned with Paris goals since there is more coal than LNG

Long-term (>2040)
a) Not compatible with 1.5/2°C goals: less coal globally to substitute with LNG
b) Compatible with business-as-usual 3°C trajectory as world still has lot of coal 2/
Caveats: Much of the LNG infrastructure is yet to be built.
1) Large-scale CCS can significantly extend utility of LNG infrastructure.
2) Low supply chain #methane leakage (<1%) critical to maximize benefits of LNG.3/

Hydrogen '2x as powerful a greenhouse gas as thought before': UK govt study

Global Warming potential (GWP) of #hydrogen is between 6 & 16, 11 the ave — GWP of CO2 is 1. Previous 2001 study put GWP of hydrogen at 5.8…
“Any leakage of H2 will result in an indirect global warming, offsetting greenhouse gas emission reductions made as a result of a switch from fossil fuel to H2,”

"much smaller molecule than #methane.. much more easily leak from existing #naturalgas pipelines if used to carry H2"
report does not take into account GWP of PRODUCING hydrogen, only impact of H2 released into atmosphere

electrolysis production of H2 wld result in 9.2% leakage frm “venting & purging”, but this wld fall to 0.52% “with full recombination from purging & crossover venting”.
