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.

130k is a new car and some savings. With ~70k annual income, this isn't that hard to achieve

Okaaaay, but I've never had a new car, have zero savings, and despite making more money than I ever have in my entire life, I still don't even clear $50k before taxes. But I guess if it's not that hard to achieve I'll just go ahead and grab these boot straps here and- oops! They broke.

I'm not saying your life is a sunshine and rainbow. Just that there's shitload of people who make more than enough to pass that threshold

[–] MnemonicBump@lemmy.dbzer0.com 1 points 13 hours ago

Yes, like I said, "around 50%" in the U.S. I'm just saying the phrase, "Chances are you're in that 10%" is highly reductive and ignorant considering that half of Americans are not, in fact, passing that threshold.
