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.

Great, up until they start eating the plastic that we're still using for stuff.

That's fine as well, because we'd have to use alternatives....you know....like before every-fucking-thing was made of plastic

It can not only eat polysterene, but more importantly break it down.

Many animals eat plastic, including humans, and that's not helpful without the ability to break it down.

Curious what does the plastic turn into when broken down, and how easy is it to separate the types of plastic the bugs can or can't eat.

We’ve known about mealworms eating polystyrene for several years now. Is there any new information worth looking at here?

Combination of enzymes in stomach of natural and poly is best.
