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.

Also yes - but frankly we're not in the position to just try one thing at a time, we're very much at the point where we need to do anything and everything we can - trees are practical for areas with lots of space, but for areas where space is a premium tech like this could work better once it matures

The problem is that we have very limited time to reduce emissions. At least so far it is dermaticaly cheaper and easier to stop most emissions at the source than to use carbon capture later, and as the plants are being developed and built largely with funds that would have explicitly otherwise have gone to reducing emissions at the source, we are seeing more damage than we would have had we foucused on emissions first and only began throwing billions these sorts of projects once most of the low hanging fruit was accomplished.

The other problem is that plants like this explicitly why companies like BP and Shell are massively scaling up oil production, because don’t worry about it. We can sell more and more oil indefinitely because the taxpayer will be able to clean up the emissions later useing only far more taxpayer money than the oil that produced those emissions was ever worth.

Best we can do is WW3, sorry 😬
