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.

That is the way humans have always been and it is not just the USA. I will be dead before the worst affects hit is the justification many think but few are willing to express. Around the world ground water is being used at rates that are thousands of time faster than replenishment.

When the water runs out, mass starvation will soon begin.

Or a big drop in animal agriculture and biofuels

That will also happen but it will not stop the hunger.

Food exports will dry up as countries hold their food for their own people (See: India's ban on rice exports) and the countries that cannot feed their own populations will implode.

The Arab spring started as protests over a jump in food prices.
