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.

The article doesn't make it clear if this is a problem of economics or a technical problem. Or a research and regulate problem.

If there are theoretical plastics that can be manufactured sustainably and recycled, if there are theoretically possible robot machines to sort (spectral lines) and if those plastics can cover the most common use cases, then plastics ARE recyclable. We just don't care to do it properly because of capitalism.

I'd really love to know the science on this. Unfortunately scientific papers also often say things like "not possible" when it's just a question of the current economic structure (ownership, patents, lack of R&D).

Most likely a technical problem. Even bacterias break it down into micro plastics, which is even more a problem.
