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 two tobacco companies Altria and Philip Morris International combined made up 2% of the branded plastic litter found, both Danone and Nestlé each produced 3% of it, PepsiCo was responsible for 5% of the discarded packaging, and 11% of branded plastic waste could be traced to the Coca-Cola company.

Less than half of that plastic litter had discernible branding that could be traced back to the company that produced the packaging; the rest could not be accounted for or taken responsibility for.

The branded half of the plastic was the responsibility of just 56 fast-moving consumer goods multinational companies, and a quarter of that was from just six companies.

This seems to me like a self-fulfilling prophecy. Of course the biggest companies with the most easily identifiable packaging are going to be the ones identified in this study. The majority of the plastic, however, is not, and it's difficult to tell who produced it.

The article addresses this as well, mentioning that this is the reason we need traceability, so we can get the true metrics on who is creating and thus responsible for the bulk of plastic waste.

The big players like Coke and others are obviously very much responsible for a big part of the problem. I just didn't see people mentioning this part of the study in the comments, so I wanted to bring it up.
