Climate - truthful information about climate, related activism and politics.

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.

NIfty! Is this data available to the general public? There's some places I'd like to check.

The resolution isn't great for the free account, and one can definitely see where the methane emissions are coming from. I checked a few of the oil fields in my state. :-( At least it's not as bad as TX. smh

There's also something of a tradeoff between spatial and temporal resolution. There are instruments with much higher spatial resolution but don't get anything like daily updates

because i am an idiot, i thought satellites were somehow causing methane emissions and was super curious how that was possible.

It isn't, i am as i said stupid

Sattrails. Aka saturation. SEE! IT ALL FITS!

Meat and dairy industry. Don't need satellites to know that.

Also leaking oil and gas infrastructure, as well as rice paddies among other sources. Tools like this are useful for doing things like enforcement of the methane emissions tax the US recently imposed on oil and gas facilities

Carbon tax! Carbon tax!! Carbon tax!!! CARBON TAX!!!!

[–] silence7@slrpnk.net 5 points 8 months ago (1 children)

It's methane, and in the US a methane tax on the biggest emitting oil and gas operations just went into effect

[–] Pizza_Rat@lemmy.world 3 points 8 months ago

Yeah, I could have said CO2e, but that's just not as much fun to chant.

Could we … burn it out of the atmosphere?

[–] silence7@slrpnk.net 14 points 8 months ago (1 children)

It oxidizes after a few years; problem is that we are adding more at a rate faster than it breaks down

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

How about drone strikes then? Like big undeclared man made sources of methane get a drone up the corn hole.

[–] silence7@slrpnk.net 2 points 8 months ago (1 children)

Three types of problems:

  • oil and gas facilities with a leak. You may release more methane by expanding the hole
  • cows. The cattle themselves are innocent. It's the people raising them are the problem
  • insurance: one off attacks don't do much as a result. It takes repeated and sustained harm to shut thigns down, which means you're likely to end up up in prison

Can you explain the cow comment further please?

[–] silence7@slrpnk.net 1 points 8 months ago

Cows use bacteria in their digestion to break down ceulose into something they can digest. Those bacteria produce methane, which the cows burp out.

Killing a few cows accomplishes nothing; you need to get people to stop raising them.

[–] naeap@sopuli.xyz 1 points 8 months ago

Not op, but: Cows emit methane, but that's just their natural state as they fart. The problem is how many we have in the meat production industry

Someone correct me, but I think that was the gist.
Or did I understand you wrong? :⁠-⁠\

According to the reports, the source appears to be...
