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.

In general, I'm not a huge fan of the LCFS as an approach; it effectively requires blending biofuels into gasoline and diesel. This has some serious scale limits and doesn't cut emissions as much as getting people to not burn stuff in the first place.

baby steps.

if you don't make little changes that lead to more little changes, which turn into big changes, because you can't get all the way to where you want to go in one step...... you won't get anywhere--ever.

Baby steps are great, and I'm a huge fan of the strongtowns mentality of "what is the next smallest thing we can do that will make progess".

Unfortunately this is a baby step nowhere, and most likely a big boy step backwards. It won't meaningfully reduce carbon emissions even if everything else stays the same. Unfortunately things probably won't stay the same, instead prices for food and transportation will increase leading towards resentment towards climate change policies and those that enacted them.
