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.

Also I am tired of minor injuries compounding year over year due to the simple fact that I am using my body as both the engine and support structure to move myself, vehicle and cargo around just to live.

I'm sorry you're getting pushback and criticism for this. As someone who physically can't bicycle and struggles with mobility, I strongly support well designed and well maintained walkable communities, bicycle infrastructure, and effective public transit. And I recognize that, for some people, the basic right to travel and work and generally function in society requires personal car ownership.

That doesn't mean I sympathize much with people who live in subdivisions off major highways with no grocery stories within twenty miles - there shouldn't be any community anywhere designed to require car ownership.

But I also don't sympathize much with people who want to ban all personal vehicle ownership from their little 15 minute utopias. Disabled people exist.

I agree with this. Cities shouldn't be car exclusive, but eliminating cars completely would also alienate villagers and people living in rural areas, in addition to disabled people.(written by an european who has family in those regions)
