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.

Just wait till Google gets the methane satellites and show that big oil is the one doing 99% of the pollution

The balance of the evidence to date is that raising ruminants responsible for something like 35-40% of anthropogenic methane emissions. That's big enough to be worth addressing.

Big oil has neglected to include well burnoffs in their calculations making those studies garbage.

A lot of the satellite data for methane is already available. Researchers aren't finding what you're describing.

What makes you so sure there can only be one singular big culprit, rather than multiple culprits of different sizes?

[–] n3m37h@lemmy.dbzer0.com 1 points 8 months ago (1 children)

No, but that 35-40% is not right by any means.

That's the point I am making. All old studies should be taken with a bucket of salt.

Ok, I see. But still, 99% seems a little much, given a billion cows, the vast majority of which kept under conditions defined by humans to increase milk and meat production.

N3m37h's apparent belief that absolutely every other industry besides oil/gas is irrelevant for climate change. Oil/gas is obviously the biggest chunk but agriculture, construction, etc. all need to change too.

[–] LowtierComputer@lemmy.world 3 points 8 months ago (1 children)

I think what they're saying is that the amount of pollution caused by oil and gas makes that caused by agriculture irrelevant.

Ass u me much?

This is what I was referring to

And if you force me to eat more fiber, I’ll be the one making more methane emissions. I do love me some beans, but I can only take so much!
