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.

Car tires shed a quarter of all microplastics in the environment. Urgent action is needed (phys.org)

Is it technically micro plastics? Vulcanized rubber particulates?

There is a significant problem with media-reporting and scientific-studies being vetted for accuracy and peer-reviews.

Plastics are organic polymerized compounds usually I think that fall under Alkyl, isoprenes, monomers ?

Rubbers are organic polymerized compounds usually under elastomers / neoprenes / butadienes ?

We NEED more nuance and not fearmongering,scaremongering and FUD about the man-made pollutants.

Rubber pollution is a thing and plastics pollution is also a thing. How do we deal with each of them may require DIFFERENT strategies and NOT CRAZY-SHIT.

Its not only rubber for car tires. There's a lot of extras to add longevity, and change performance in certain conditions.

Plastic is mostly made from hydrocarbon chains. So are rubber polymers it seems.

Not sure if it matters if the plastic is from a tree or pumped from a really old tree.
