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.

Not sure what more they could have done. A drought during rainy season, a quick response to clear dry vegetation/trees is clearing vegetation that could rebound if it rains soon.

From climate statistics of 2024, record monthly rainfalls over 24 hours were 52% higher than average, and record low rainfalls 38% higher than average, globally. 2023 was bad too. These stats, in a non global warming world, would drop each year as the bar is higher each year. Costs of disasters are growing exceptionally.

As bad as the current global warming impact is on just the US's sustainability from disaster/insurance spending, calls for subsidized insurance doesn't help. It just shifts burden to tax payers/debt, and like FEMA's historically cheap flood insurance, encourages rebuiliding where it is risky. Neither does "Insurance reform" that prevents victims from making successful claims (as in Florida).

We may already have reached a point where climate disasters cost more than the profit potential of oil industry. Certainly more than their tax payments. As more of the US is destroyed, remaining housing scarcity means higher insurance coverage. Autos artificially protected means higher prices and insurance costs. (oil) "energy dominance" policies is climate terrorism to ensure a worse outcome.

One simple "helpfulness" in rebuilding is metal roofs that last 50 years and can support solar for that long too. They are fire proof. Less forest, with utility/community solar, becomes necessary from just an insurance perspective. Also related to forest fire problem, CA electricity rates are sky high because somehow utility negligence for past fires has to be paid by state wide rate payers instead of shareholders. CA governance that is captured by utilities and insurance, fail to help CA progress and resilience.

Short term, there's really not much they could have done better. These were extreme conditions and they were bound to cause fire to a large extent in the current context of peri-urban development and forest mismanagement.

Long term, things could have been different but it would require major political and social changes in how we build cities and how we manage our wildlands. Happy to go into more detail if you are curious.

Destroying and rebuilding homes (AFAIU, most destroyed were over 60 years old) is a tough option. Really, removing forest for solar is the best, only practical, solution. This should be global adaptation to high value forest homes/communities, because drought risk is everywhere.

Surely continuing to subsidize fossil fuels will solve this.

Really does a good job highlighting how the fire is spreading so fast. Each of those flying embers just has to get lodged somewhere flammable and woosh

Enter through the soffit vent of the attic, a vent that can't be closed on the outside of the house. Land in the cellulose insulation, which is ostensibly shredded magazines.

Goodbye, house.

They make fire resistant vents for this exact reason

Well, that just sounds like gross negligence by the developers designing/building homes where bushfires are a thing.

How my intestines feel after I eat McDonald's

Good to see McD’s expanding their business to serve the afterlife. Should have known hell would be a wind-whipped, fiery capitalist wasteland.
