I'll be curious to see how big a blip we get in the atmosphere methane number after the huge leak from the Nordstream pipeline sabotage
This was the largest methane leak ever seen.....but was it large enough to show up in the global atmosphere data?

Cheers!

Tanad,
Do you have an opinion on how the Ukraine war will shape future nuclear development?
I can see various forces either increasing its use or making people more afraid. But I have no idea which will predominate.
Any thoughts?

Are you considering nuclear energy or nuclear weapons?

Appears not even visible
Maybe seen in some deep statistical analysis

This is a decent article, though it seems to omit methane from arctic tundra and undersea sources, which are quite substantial now the arctic has warmed so much.
Where methane comes from
About 600 million metric tons of methane are released into the atmosphere each year. Estimates suggest two-fifths of these emissions come from natural sources, mainly rotting vegetation in swamps. The remaining three-fifths of emissions come from sources tied to human activity.
Emissions from the fossil fuel industry are well over 100 million metric tons a year and grew rapidly in the 1980s. Natural gas, which in the UK heats homes and generates roughly half of electricity, is mainly methane.
Gas industry leaks are widespread at wells and pipelines and from distribution pipes under streets and home boilers. The coal industry was responsible for up to one-third of fossil fuel emissions between 2000 and 2017 via ventilation shafts in mines and during the transportation and crushing of coal for power stations.
Agriculture, producing about 150 million metric tons a year, is the largest overall source. As are urban landfills and sewage systems, contributing about 70 million metric tons annually.
Scientists can identify sources of methane by studying the proportion of carbon-12 to carbon-13 in the atmosphere. These different forms of carbon – chemically similar but with different masses – are known as isotopes.
Biogenic methane, made by microbes in rotting vegetation or in cow stomachs, is relatively rich in carbon-12, while methane from fossil fuels and fires has comparatively more carbon-13.
For two centuries, rapidly expanding gas, coal and oil industries steadily drove atmospheric methane richer in carbon-13. Since 2007, that trend has reversed, and the proportion of carbon-13 in atmospheric methane has decreased. Although fossil fuel emissions may still be growing, soaring methane emissions are now primarily the result of faster-growing biogenic sources.
Why are biogenic emissions growing?...

The 'peak oil' story is not over by any means. Fracking was a desperate and ruinous sort of pause, which has been used to crank up demand.
