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.

More than two-thirds of the world’s countries endorsed an agreement to retool the global food system, though it’s vague, lacks concrete targets, and is nonbinding. The United Nations food agency issued a landmark report laying out what it would take to align the global food system with the goal to limit average global temperature rise to manageable levels. The United States and the United Arab Emirates together committed about $17 billion toward agricultural innovations to address climate change.

In the next 100 years I predict that we go back to beans as a protein source, humans do not need to be eating the amount of meat we do. Too many cow farts fucking biz up.
