Why this is a boon to the #FossilFuel industry:
#Wetlands are natural carbon cycling, so despite their huge contribution to greenhouse gasses, they are not including in footprint calculations. But #CowFarts are. Natural enteric fermentation is 75% of the Ag methane emissions. Drop that and anthropogenic Ag emissions are only 36MT...
To illustrate the error inherent in including natural #CarbonCycle #CowFarts in #footprint calculations...
Consider that 1/3 of all #MethaneEmissions come from #wetlands. https://svs.gsfc.nasa.gov/5054
CO2 drawn down by photosynthesis and stored in plant material is going to return to the atmosphere via decomposition - be it land, stomach, or wetland processes.
Should we consider a developer's plan to destroy a wetland carbon negative because of methane? that would obviously be ridiculous
Methane is an important greenhouse gas that’s contributed to around one third of global warming. About a third of total methane emissions comes from wetlands. Wetland habitats are filled with things like waterlogged soils and permafrost, which is what makes them sizable carbon sinks. But as a warming climate causes wetland soils to warm or flood, carbon is released into the atmosphere as methane. Methane is an important greenhouse gas that contributes substantially to global warming. On a molecule by molecule basis, methane is much more efficient at trapping heat than carbon dioxide, the main driver of warming. Though human activities, including agriculture, oil and natural gas production and use, and waste disposal, collectively contribute the majority of methane to the atmosphere, about a third of total methane emissions comes from wetlands. Wetland habitats are filled with things like waterlogged soils and permafrost, which makes them sizable carbon sinks. However, as the climate changes, these carbon-rich soils are vulnerable to flooding and to rising temperatures, which can release more carbon to the atmosphere in the form or methane. Understanding methane emissions from natural sources like wetlands is critically important to scientists and policymakers who are working to ensure that changes in natural systems don’t counteract progress in combatting climate change made by reducing emissions from human activities.This animation shows estimates of wetland methane emissions produced by the Lund–Potsdam–Jena Dynamic Global Vegetation Model (LPJ-DGVM) Wald Schnee und Landscaft version (LPJ-wsl). LPJ-wsl is a prognostic model, meaning that it can be used to simulate future changes in wetland emissions and independently verified with remote sensing data products. The model includes a complex, topography dependent model of near surface hydrology, and a permafrost and dynamic snow model, allowing it to produce realistic distributions of inundated area. Highlighted areas show concentrated methane sources from tropical and high latitude ecosystems. The LPJ-wsl model is regularly used in conjunction with NASA’s GEOS model to simulate the impact of wetlands and other methane sources on atmospheric methane concentrations, compare against satellite and airborne data, and to improve understanding and prediction of wetland emissions.

A refreshing talk by #BernhardStoevesandt on the current state of the discussion on #climatechange and the necessary and possible changes from a #scientific perspective.
Not putting all the blame on #cowfarts, no #greta agenda.
Conclusion:
It's not so much a technical issue, it's a political one!
#Dutch #cows soon might need a permit to walk on the land..
As if they frat more when they walk outside and eat fresh #grass..
But hey, we will need expensive #technology and bullshit #bureaucrats to crack down on the #farmers.
While the traffic jams next to the #farm lands create for more #toxic #carfarts on one day , then all the #cows do #cowfarts on the land in 1 year.
