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.

I will note that these are scope 3 emissions, so it includes the emissions associated with fossil fuels extracted by these firms and burned by others, as well as those from electrical generation when end consumers use the electricity.

These are Scope 3 Category 11 emissions, corresponding to "use of sold products", however this has been modified to quantify emissions from each fossil fuel company’s net production of oil, gas, or coal as opposed to sold products.

'Hold them to account' makes it sound like they at least had to own up and honestly admit it. Maybe they have, while simultaneously funding climate denialism, us politicians for denial, and otherwise funding campaigns to deny harm from hosts of pollutants, many systematic at this point, poisoning everything.

Insect populations are down 90 pc since the 90s, something is fundamentally wrong, they know their parts in it, and pay to make sure we do not know. Poisoning everyone to save a dollar.
