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 misleading accounting behind your ‘recycled’ plastic: A convoluted credit system allows companies to label virgin plastic as recycled. Here's how it works. (grist.org)

TLDR

Recycling plastic produces a substance which is more easily burned as fuel than made into new products.

So companies can buy some of this substance from a plant that produces it from old plastic, set it on fire, and then claim that their products are some percentage recycled.

What's funny to me is that, in a way, this is still better because it reduces the use of virgin oil for fuel. But instead of calling the fuel "recycled fuel", they decided to call the plastic "recycled plastic". It's like these evil fucks will always choose the most evil shit no matter what.
