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.

Yes... plastic recycling can work, in theory, but the financial incentives are not naturally inclined to be in a way that recycling is feasible, since externalities encompassing the damage that plastic production has to our world are not accounted for in its price. (Caveat: the products that can be made from recycling are physically unable to be perfectly like the previous products they came from)

Like the cost burden of tobacco use being put on both users and producers, plastic must be dealt with the same way in terms of taxation levies so that plastic alternatives and plastic recycling are competitive compared to new plastic from oil by-products.
