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.

Commercial fishing is destroying ecosystems around the world. Is anything being done about it?

I'm gonna get called a misanthrope for this -- but we've gotta stop having children. This "Line go up", shit of ours can't keep going on or we're going to starve ourselves out of existence.

I definitely get where you're coming from, but I think population reduction comes naturally from things like abortion rights, good family planning provisions, and a lack of poverty. Countries with those things are seeing a decline in population without making having children into a moral issue.

Extra point is that, although the population is up, the amount of meat eaten is waaay up. Just looking at that one issue, we can solve over fishing pretty easily without requiring any change to the current population numbers.

That's okay, most people don't want to follow the other major advice of eat more lentils, way more.

I don't think that should be the main worry. People are already having less children, below replacement in most of the developed world. Meanwhile the trend on meat consumption is going up, we should focus more on trying to stop that.
