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.

Contrary to "common wisdom" and industry lies, LNG is not significantly better emissions than coal. When exported, especially across the Pacific to e.g., Japan, it's sometimes within just a couple of percentage points the lifetime emissions as coal.

Solar is already a vastly cheaper form of energy than fossil gas and wind is rapidly going down those learning curves (it's already comparable in many geographic areas. The issue that US energy utilities simply don't care. They only really know how to deal with "dispatchable" power generation. They don't want to change. They don't want to adapt. They'd rather spend more (ratepayer) money doing things the old way. Even though we already have the technology to deal with nearly all of the "reliability" issues that come with renewable generation.

Your voice can influence this. In many states, the energy utilities are regulated by a regulatory commission -- and those commissioners, frankly, aren't getting a steady stream of feedback. They are often elected officials. I've got one of my commissioner's cell phone number -- they can sometimes be THAT accessible -- and they're in charge of holding these monopoly utilities to task.

We don't need a global socialist revolution to seriously address climate change. Tons of progress is already happening, even under the regimes we're currently stuck with. Don't just read articles. Talk to friends and family. Take action. Make calls. Vote. Donate. It's a still a winnable battle so long as you don't let the doomsayers suck all the air out of the room, but it gets less so every day that people stand by.
