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.

I’m not a fan of these rapid news with very little context.

What’s going to happen, if it hasn’t happened already, is that companies and corporations are going to play with words in order to seem like they’re more climate-friendly than they are. Few people disagree that fossil fuels needs to be reduced but without knowing more context, it’s hard to say whether an firm that commits some amount of money into another firm that has some role in fossil fuels is “a bad thing”.

The biggest one I hate right now is “carbon neutral”. “Hey we make a shit ton of pollution but we also recycle 0.5% of our supply chain. Our imaginary math works it out that it means we aren’t polluting because that’s absolutely how that all works”
