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 would hazard saying "environmentally effective" here unless we are willing to ignore some of the other large environmental issues with meat production outside of just green house gases emission. Plant-based foods are lower not just on GHG emissions, but water usage, land usage, eutrophication, fertilizer usage^1^, etc.

There's all kinds of other pollutants such as Nitrogen runoff. The rise of the pig farming is has helped fueled a crisis in Nitrogen runoff in the Netherlands for instance

There's the high level of antibiotic usage to maintaining the high levels of production fueling antibiotic resistance.

And so on.

If we do want to look at the suffering, we should also note that chicken farming does not just keep things the same, but actually makes it worse with more chickens required than other creatures due to their smaller size.

^1^ Even less synthetic fertilizer even compared to the maximal usage of manure per https://www.sciencedirect.com/science/article/abs/pii/S0921344922006528

EDIT: I should also mention that land use change (deforestation) factor can change as you rapidly increase these industries size. Deforestation makes up a large portion of beef's current emissions. Plant-based foods require overall less cropland due to not needing to grow any feed and removing that energy loss. This is not the case for chicken production. Currently beef does make up the majority of Amazonian deforestation, however, the second largest portion is growing animal feed primary for chickens. Switch from beef to chickens and you might risk just moving around where the deforestation comes from
