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.

Injection Wells Will Haunt Us Forever (powering-the-planet.ghost.io)

It has been known for a long time that injection wells are not a permanent solution and that what we blast underground will come back to us. Will it take 100 years? Fifty? One? We don’t know until we try and boy have we tried. And in the case of the oil industry we can see how that is failing in the Permian in Texas. And in Ohio. And across the country where we have more than 180,000 injection wells. I wrote about some of these failures in July.

The thing about the oil industry’s plan to capture carbon and store it underground is that it only works if the storage is permanent. And yet we know that is impossible. When will we learn that blasting carbon dioxide underground is a failed strategy? Earlier this month, actually. The very first carbon storage project has already failed. We tried again, we hoped, we failed.

Well, that is nightmare-inducing.
