Climate - truthful information about climate, related activism and politics.

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.

They sure are. It sounds like this video is examining these things in isolation instead of looking at the wider social effects that also help counter climate change. For example, if you build houses closer together, you'll not only reduce heating and cooling costs, you'll also reduce the monetary and carbon costs of infrastructure, you'll improve the efficiency calculation of public transit, and you'll make bikes more viable. One change with knock on effects that help three different sustainability areas. One change that literally costs negative money and also helps the environment. How did this not make the list??

Also shooting rich people dead only costs a hunting rifle and some bullets, and it prevents hundreds of private jet flights a year.

The video was analyzing the effects of the costs until 2050. Things like housing density increase slowly so might not be impacted substantially by 2050. Also most of the best solutions have a negative cost projected out to 2050, so no killing people isn't a better solution.
