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.

Yeah, when I worked retail in a strip mall 15 years ago the outside windowsills got covered in this nasty black dust every day. Spent an hour of each shift cleaning it. One day the district manager mentioned that the company had it tested and it turns out that it was from tires wearing and giving off dust.

I've always thought about that. If one tiny shop in a strip mall got so gunked up with this stuff, what's it doing to the rest of the planet?

What's possibly equally frustrating is why did no one else think of this before?

Like we know everything wears down, but nobody seems to think "where does the worn material end up?" I imagine it's mostly because it's a product and so "had sale, don't care."

Scientists did think about this, no one listens though.

Hm I live next to a busy street, and my window slits keep filling up with a black powder that turns to sludge when a cleaner is added, I'm tempted to get it tested now.
