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 always want to reply with that chart on every post about some magical new climate technology. Nothing really matters until we stop pulling carbon-based fuels out of the ground and lighting them on fire. That’s it. That’s the only thing that matters. Wind and solar are great but we’re still approving gas/coal/oil projects, at least globally.

It’s like with the water crisis in the American West. They guilt trip individuals into feeling bad about taking showers but it’s like 80% agriculture. And the majority of that is for animal feed. (I’m not saying everyone go vegan. That’s about as unrealistic as asking everyone to stop fucking to keep the population from growing. I’m saying don’t grow alfalfa in the fucking desert and then blame people who bathe.)

where did you get this data? it can't possibly be right

edit: it's robbed of context. it's only illustrating water use in the Colorado River basin, and even at that is being misleading: for instance, corn silage is a byproduct of grain corn. that water doesn't magically re-enter the water table if we don't feed it to cattle, but by feeding it to cattle, we are able to reclaim some of that water use.

I skimmed this and clicked a few of the references. it does use poore-nemecek 2018, so I'm skeptical of all of the other data that's included. of course going through a piece the size that you linked to evaluate it for its scientific integrity is a project all onto itself and I'm at work at the moment. I encourage you to look at the methodology for each of the claims made in your link.
