Auch wenn das meiste bekannt ist, hat die Sendung eine andere Sicht auf Methan und enthält tolle Denkansätze zum Gegensteuern. 👍🏻

Musings on Arctic permafrost.

The thaw is going to release ancient carbon. Depending how hot we let it get, low anthropogenic emissions less so, high levels let the release continue for centuries to come. See chapter 4 https://iccinet.org/statecryo24/

But I'm thinking: what is permafrost?
It's an ancient swamp, a bog. And thawing the bog also revives the bog processes.

So we're concerned about carbon release in form of microbes burping #methane while they're feasting on the old, dead plant material below the "water" surface.

But what about the other bog property, the one that hides new plant material under water = burying contemporary carbon?
It's a near-permanent drawdown of CO2. Just think about the well-preserved corpses archaeologists examine for clues on cultures thousands of years ago.
That's ancient CO2, safely hidden away from the atmosphere.

And Arctic permafrost is becoming such a bog again.
Yes, the methane release from microbes is bad.

But as long as thawed Arctic permafrost doesn't dry up, CO2 drawdown will occur as well, and in a place where it hadn't occurred before.

Luckily, CMIP6 sees a considerable, continuous rise in precipitation for the Eurasian permafrost region https://climatereanalyzer.org/research_tools/monthly_tseries/
So the new, huge bog is not at risk of drying out.
And some water from the thaw is also going to stay in the soil.

From what I read about permafrost so far, I do not recall that a number is put on the likely CO2-storage dynamics.

Only methane release from permafrost thaw receives numbers. Pretty big numbers, too. Depending on human emissions, 300-500 Gt CO2-eq per century, see the link above.
= +0.2 to 0.3 °C per century, (short-term heating from actual methane is higher).

But from lengthy discussions on Twix a few years ago, I recall that wetland/peat researchers aren't at all concerned about renewed methane emissions during re-wetting of dried wetlands elsewhere.
They argue that the expected new CO2 drawdown, plus ending CO2 emissions from the dried-out wetland (globally 2Gt CO2 / year),
outweighs the heating impacts of methane production.

To my unlearned mind, when I transfer this assessment to new bog activity in the permafrost region,
the thaw would even be a reason for re-joicing... 😱 😁 🖖🏽

#Carbon14: Another underestimated danger from #nuclear reactors

"There are a number of radionuclides released from nuclear energy facilities. This paper highlights carbon-14 for a number of reasons:

- Carbon-14 is radioactive and is released into air as #methane and #CO2

- Before 2010, carbon-14 releases from nuclear reactors were virtually ignored in the United States. Today only estimates are required and only under certain restrictive circumstances.

- There is no good accounting of releases to date, so its impact on our health, our children’s health, and that of our
#environment remains unknown, yet environmental measurement is possible, but can be challenging under certain
conditions.

- Carbon-14 has a half-life of over 5700 years and the element carbon is a basic building block for life on earth. Therefore, “it constitutes a potential health hazard, whose additional production by #anthropogenic sources of today will result in an increased #radiation exposure to many future generations.”

- Like #tritium, it can collect in the tissues of the fetus at twice the concentration of the tissues in the mother, pointing to its
disproportionate impact on the most vulnerable human lifecycle: the developing child.

The element carbon is found in all organic substances. Carbon is also a primary constituent of #GreenhouseGases that are responsible for #ClimateChange, such as carbon dioxide (CO2) and methane (#CH4). Carbon-14 (c-14) is a radioactive form of
carbon that occurs in nature and is also newly formed in nuclear power processes.

"Carbon-14 is a health concern because it is released from #NuclearPower facilities as radioactive carbon dioxide and methane, traveling readily in the local and global environment.

"Over time, carbon-14 becomes part of organic material including food, and has a half-life of approximately 5,730 years, decaying by a type of radioactive particle called a beta. Its hazardous life is 10-20 times its half-life, meaning that harmful exposure to man-made carbon-14 can last for hundreds of generations. The radioactive carbon forms as a byproduct of fissioning of uranium fuel, through a process called activation. The final step is a chemical reaction between carbon-14 and oxygen or hydrogen, which forms methane or carbon dioxide. The radioactive carbon-14 formed by this process is brand new and would not exist without nuclear fission.

"During its long hazardous life, carbon-14 could be responsible for gross physical or
mental defects, stillbirths and childhood deaths, embryonic and neonatal deaths into the many millions over the life of the isotope.

"These millions could be underestimated five times or more. Carbon-14 could also be responsible for #leukemia, bone and other #cancers."

"Current atmospheric concentrations of #CO2 are higher than at any time in at least two million years. Concentrations of #CH4 and #N2O are higher than at any time in at least 800,000 years.”

@W_Lucht

Hey Wolfgang, sorry for OffTopic.

I've been searching on Umweltrat-de for information on the embedded CO2 in CCS.
You know, like, how much more gas has to be burned in order to capture the CO2.
And additionally, how much energy is required to make the solvent that goes into the CCS process, and how much energy goes into transport and storage.

says "10 to 40% more energy" is required, but then quotes this surprisingly old source from 2006... https://www.jstor.org/stable/48526261?refreqid=excelsior%3Af975048a0b74cc357bf303fa24ddce1f

names Bongartz et al 2015 for
"Gleichzeitig sinkt aufgrund des Energiebedarfs für die Abscheidung der Wirkungsgrad des Kraftwerks je nach Abscheideverfahren , wodurch der Brennstoffbedarf erhöht wird."

I don't have access to Bongartz et al 2015. Do you? Where did their information come from, and is it publicly available?

The energy carrier used in a power plant itself is necessarily the same as used for power generation, I guess.
But the energy for making the solvent and for transport and storage of the captured CO2 might be from a different source, potentially renewable. So that's why I'd like to have this split into two parts.

If a CCS+gas power plant needs, lets say, 3x more gas to actually remove CO2 from power generation compared to a gas power plant without CCS,

this CCS+gas incurs 3x more methane leakage!
AND also 3x more CO2.
So a test installation that allegedly removes 1Mt of CO2 per year, only removes 330kt from power generation, and the remaining 670kt removed were CO2 from the removal process itself?
Or in other words, 1Mt removed leads to 2Mt emitted?

I think, this information must be out there in the public debate. Especially now when the Green's newly legislated gas power plants of 12.5GW have been increased by the new government to 20 GW.

CCS means more gas is burned. The removal efficiency is bad. The methane leaks alone are making this endeavour even worse than just burning coal.

Thank you for your help!

Greenhouse gas from livestock digestion in Equatorial Climates 🧵

Along the Equator, it mainly is sheep and bovines that account for methane emissions.
The biggest producers are Ethiopia and Sudan (South Sudan included).
