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.

Experts say China's targets to cut pollution don't go far enough (apnews.com)

For the first time, China set a specific target for reducing emissions. However, it falls short of what analysts say is needed to meet the Paris goal of limiting average global temperature increase to 2 degrees Celsius (3.6 degrees Fahrenheit), and ideally to 1.5 degrees Celsius (2.7 Fahrenheit), compared to the 1850s.

Xi announced in a video message to a U.N. climate meeting in September that China would cut greenhouse gas emissions by 7% to 10% by 2035, and would strive to do even better than that.

Modeling by multiple climate experts shows that China would need to cut emissions by around 30% for the world to be on track to the Paris goal.

“This is disappointing as China has the opportunity to decarbonize faster,” Norah Zhang, an analyst at Climate Action Tracker, said after Xi’s announcement.

Previously, China had not pledged to reduce its carbon dioxide emissions. Instead, it promised to reduce its emissions relative to the size of its economy — so they could still grow but at a slower pace than the economy. Its goal has been to have CO2 emissions peak before 2030.

I’ll take whatever they’ll give us, since the US has “burn as much coal as possible and make renewables illegal” as their climate goal.

México too, we're burning fuel oil daily because the expresident hated green energies and the current one does whatever the cult leader tells her to.
Also cutting down trees and fucking up the environment to build their illegal mega projects.

On a lower scale, there was a civil organisation trying to replant the streets so they stopped being concrete deserts but the last thing I knew was the goverment was trying to get them in jail for damaging public property.
