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.

You would think, but yes, a lot of people really do routinely buy more perishables than they need.

I owe my perspective on it to this essay. It doesn't talk about money wasted when food goes bad, but it was the first thing that came to mind when I read it—I didn't just pay $1.86 for those green onions, it also cost me $1.86 worth of green onions when I threw them away.

People don't even notice how much money they waste on food they never ate because once that 2 lbs of bacon is in their fridge, they no longer assign a dollar value to it. When that bacon goes bad without even being opened, they didn't lose $10, they lost 2 lbs of bacon, and the thought that enters their head is "I should get more bacon"
