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.

It does, but it will also bind a lot of the micro plastic pieces into the concrete matrix, which, I think (and, again, as I said, I haven't actually gone looking for any research on this), would keep them from entering the environment. If the concrete is then recycled, typically by crushing and using as aggregate, it would further trap the particles. It's not a perfect solution, but I don't think there is a perfect solution to plastics in general, we just have to find less harmful alternatives.

Best solution imo is burning it with a filter after use. Gasification will happen anyway but this way at least it doesn't damage ecosystems.
