Capturing methane is a good thing. It’s 86 times more potent a greenhouse gas than CO2.The leftover manure is also used as fertilizer. This isn’t greenwashing.

Tying this process exclusively to factory farming seems disingenuous. Cows still produce methane whether on one factory farm or a hundred family owned farms. Factory farming is shitty (pun intended) but capturing methane is still a good thing.

I have to agree.

Just to pile on about the operation of factory farms. They often use a substrate like sand, which picks up the manure/urine, but then is rinsed out to reuse the substrate. This manure slurry is held in ponds and often just dumped on neighboring farms with little care to whether upcoming rains wash the slurry into waterways or overburden the capacity of soils to filter ecoli and other fun stuff before it hits the neighbors' drinking water wells.

Running this through a digester really helps so much from an environmental point of view.

Otherwise it's really a shame about the life these factory farms animals live.

Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
