Climate - truthful information about climate, related activism and politics.

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.

Because this "one trial" was the literal best-case scenario, and it still sprung a leak that would cost more to fix than they could gain by banking carbon sequestration credits.

All I’m hearing is the first experiment failed, and y’all would rather give up than fix it.

Yeah, obviously I'd much rather that R&D budgets got spent on things that might actually make a difference rather than new ways of kicking the can down the road for future generations to deal with.

You're weirdly defensive about this idea. What's up with that? Daddy got some investments in the fossil fuel industry?

The whole article is weirdly dismissive of new technology.

It's not new technology, for one. We've been using injection wells like landfills since the 1930's because it's cheaper than treating and disposing of wastewater safely.
