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 sad thing is, only types 1 & 2 plastics are recyclable in any real fashion, and sometimes not even then.

That means types 3 through 7 are better disposed of in the trash, where at least they’ll be sealed into a landfill instead of being shipped overseas to end up somewhere far less environmentally secure.

These types are the numbers inside the recycling symbol. Many things are mixed and matched - a plastic bottle might be a type 1 (recyclable), yet its screw-on cap is typically a type 5 (largely non-recyclable). Always try to find the recycling symbol and dispose of anything not a type 1 or 2 in the trash.

#7 isn’t even a material, rather “other.”

PS (#6) and plastic films can be recycled at dedicated drop offs.

It depends. My municipality recycling bins take type 5.

I noticed a bottle was recyclable but the label wasn’t, was annoyed that they would do that because I doubt there are many who would read the label to know that

But even recycled plastic just gets shipped to SEA for them to deal with instead of actually being recycled so I guess it doesn’t matter
