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.

Want to plant trees to offset fossil fuels? You’d need all of North and Central America, study finds (apnews.com)

The paper effectively makes the point that it’s financially impossible to offset enough carbon to compensate for future fossil fuel burning, said Daphne Yin, director of land policy at Carbon180, where her team advocates for U.S. policy support for land-based carbon removal. And the idea that companies would be required to account for the downstream emissions from the fossil fuel they extract is a “fantasy,” she said.

I hate how their is this (seemingly purposefully) effort to just talk about carbon, probably because it's an abstract invisible gas that nobody really can imagine. The problem is so, so much larger and loss of habitat is a huge fucking problem. Bird and insect populations are fucking plummeting and nobody seems to give a single shit or ever thinks about the ramifications.

Plant trees, and everything else. Wild native flowers are nice too. I want a world that is teeming with life, not some barren wasteland.

Plant a tree, let it be, don't mow around it, leave the leaves, and when it dies or breaks, also leave it there, it's all alive!
