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.

Guterres made an address to the UN general assembly on Wednesday on his priorities for 2025, in which the climate crisis was a major theme.

“Who pays the price for climate destruction around the globe? Not the fossil fuel industry pocketing profits and taxpayer subsidies as their products wreak havoc,” he said. “Every day people suffer: with their lives and livelihoods; with higher insurance premiums, volatile energy bills, and higher food prices.”

“Today, governments around the globe spend nine times more making fossil fuels cheaper than they do on making clean energy more affordable for consumers,” blocking climate action, Guterres said. “We must tear down these walls.”
