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.

Fast forward 250 years and the staggering health consequences of burning fossil fuels continues to impact millions. A recent study linked oil and gas particulate pollution with 90,000 premature deaths in the U.S. each year...

Outdoor air pollution worldwide kills 3 million people each year according to the Organization of Economic Development (OECD) and costs the global economy $3.5 trillion. About half of those costs are linked to pollution from fossil fuel road transport within OECD countries.
...
What other industrial sector is allowed to inflict such enormous externalized costs on society without compensation? Even the tobacco industry was eventually held accountable for the billions spent treating ailments related to their dangerous product.

Why is the oil and gas industry somehow exempt from the well-documented burden that burning fossil fuels places on the health care system?
