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.

You know how you know when Newsom’s lying? His lips are moving. He knows Climate Change is an existential threat, but also that he’s rich, so his family won’t face the effects the way the 99% will. The closest he’ll get is his vineyard will use more water, but don’t worry, I’m sure there’s some PUC decision that will keep his water rates artificially low.

California’s current leadership doesn’t really care about climate change, because if they did, the PUC wouldn’t disincentivize rooftop solar through NEM 3.0 and would instead offer tax credits. It’s too bad the common citizens of this state aren’t valued like the profits of Newsom’s friends at PG&E.

Heck, if they really cared, electric vehicles would be progressively subsidized so more working class people could afford them. Instead, workers keep older ICE vehicles longer because they’re paid off (hopefully) and replacements are financially out of reach, even if they’re much cheaper to operate. It’s like housing. A reasonable mortgage payment is much cheaper than rent, but if you are paying rent, you likely don’t have the down payment to get an affordable monthly payment. A house down the street went into escrow the day after listing at $1.7 MM. The nearly identical house next door to them gets $4-5k a month in rent. How is anybody going to have enough money saved up to get their mortgage into a reasonable range, setting aside the $1500 a month for property taxes? The family living next door would need a down payment over $1MM to get even close to their current rent, which is already $50-60k a year! Just their rent is more than the median income for one person, so they likely wouldn’t qualify for a loan that’s exactly the same amount as their current rent even with that staggering down payment.
