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.

Limiting the impact corporations have on the environment via legislation is one highly effective way. But I'm just a person from the 89% of the population with this stance. So asking me isn't all that useful. Asking at the demonstrations in a manner which takes account of each response is a much more logical way to help figure this out. Additionally, there's definitely organizations who've done a lot of work here and have plans drawn up on these matters.

Okay, so you pass the global laws which enforces emission limits. The corporations comply. Very soon, most of humanity's physical activities stop, including not just amenities but basic human life support. People start rioting and dying en masse. Earth population plummets to less 10% of the current population, possibly a lot lower. The Earth ecosystem, while severely damaged by the collapse, recovers, in the very long run.

But wait, this would have happened anyway, albeit slower.

Can we soften the blow, by cushioning the fall? Only in theory. In practice, the global system is out of control. We have about zero degrees of freedom collectively.
