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:

Summary

The UN declared 2024 the hottest year on record, capping a “decade of deadly heat” where all 10 of the hottest years occurred.

UN Secretary General António Guterres urged urgent action to slash emissions and transition to renewable energy in 2025 to prevent further climate breakdown.

The World Meteorological Organisation highlighted record rainfall, flooding, cyclones, heatwaves, and wildfires, with 26 of 29 extreme events in 2024 linked to climate change.

Dangerous heat days increased by 41 this year, emphasizing the need for global cooperation to address escalating heat risks.

Surely I'm not the only one who sees articles like these all of the time and just wants to shout, "WE KNOW!"

I know there are people who refuse to look up and acknowledge reality, but they are not reading these articles. And the politicians and the rich people controlling the politicians don't give a shit.
