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.

I absolutely agree with you. Meat is something that has a big impact on the climate and this is something that we as the consumers actively can control. If society decides to buy less and instead higher quality meat the demand will go down and therefore the CO2 footprint. However, this is nothing that is possible without the government supporting this change.

this isn't causal

I may have articulated myself badly. What I mean is the following: If I decide to instead eat e. G. 1kg of low quality meat every week I am responsible (by eating meat) for an amount x of CO2 emissions. If I now switch to only 500g of higher quality meat the amount of CO2 emissions goes down to about 1/2x(I know this isn't exactly true, due to the lost efficiency, but for bigger reductions its absolutely true, that the amount if CO2 you emitted goes down).

I don't think that's true. those emissions happen regardless of whether you eat it. they happen regardless of whether you buy it.

Source please.

Your analysis undermines genuine science by disregarding the reduction in demand which reduces the supply and forming a data set with a sample of 1.

reduction in demand which reduces the supply

this isn't causal

[–] commie@lemmy.dbzer0.com 0 points 2 weeks ago

it's obvious that the emissions happen before you decide whether to purchase a product. that's how linear time works.

and this is something that we as the consumers actively can control.

didn't you try that?
