Los Angeles Fire Department funding was cut by over $23M only a few months ago. The fires are currently being fought by a skeleton crew of remaining fire fighters and volunteers. Can't say if that funding would have prevented it, but cutting it definitely has not helped. Source: https://www.politico.com/news/2025/01/08/los-angeles-fires-m... Edit: Changing a word, "gutted" -> "cut"

I really don't understand how SoCal and California residents in general find the the state's response to wildfires in the last decade to be acceptable. Not only have fire departments seen cutbacks, but so has the forestry needed for preventative measures. What really bugs me is what I find to be a disinterest and lack of belief in vastly expanding the fleet of water dropping aircraft. Letting fires burn to the extent…

Not an expert: I think one of the issues is that there's only a handful[0] of satellites with the appropriate infrared instruments, which means that any given point of Earth is only sampled at a multiple-hour cadence.

It's a generic problem for any sensing problem that's real-time + low-orbit.

I speculate adding instruments to large LEO constellations, en masse, would solve that problem—though I have no clue if that's practical. (Perhaps if the same instrument were doing other kinds of real-time imaging, you could piggyback wildfire alerts on that datastream, and the get the functionality essentially for free?)

edit: More info:

- "Geostationary satellite sensors view the same area of Earth’s surface at all times while polar-orbiting sensors, such as MODIS and VIIRS, typically view the same area of Earth’s surface twice daily. Consequently, geostationary satellite sensors can provide repeated observations on a sub-hourly basis, making it possible to detect fires which may not be detected at longer temporal intervals. Geostationary satellites provide data at 10-15 minute intervals, so they can detect more fire events and capture their growth and change. However, the spatial resolution of geostationary satellite data is coarser and therefore less sensitive to small fires."

California has a problem with overly aggressive fire suppression over the last 100 years creating a buildup of extra-flammable burnable areas. Literally, you need to let a certain amount of burning go on, continuously over time, so that the burnable areas aren't over-fueled tinderboxes that get very hot, very fast. Part of this is using controlled burns to mitigate the buildup, another thing that's been under-resourc…

That's true in general but not really applicable to these fires. It's mostly chaparral that's burning, and most of the dry brush has built up over only a few years — not 100. We had two years of heavy rains that caused a lot of brush growth, and then this season it all dried out.

Controlled burns in that terrain are impractical because there are too many structures nearby and a controlled burn can turn into an uncontrolled burn in minutes. A more realistic approach would be expanding defensible space and culling non-native flora.

The problem with that though is that the overall budget includes big ticket items like pensions and overtime. And cuts often directly are from live services. So even though it’s 2% of the overall budget, the cut could still be significant to the availability of firefighters and crucial things like response times.

I recommend to everyone to get out of cities and counties that have large pension liabilities. You will be less safe, your kids will be educated more poorly, and your quality of public services will be whittled away because the money is going to retirees and debt. E.g. Retirement benefits and debt service took up 43% of Chicago’s budget in 2022: https://www.nytimes.com/2024/12/30/opinion/chicago-illinois-... . A deca…

And go where exactly? To towns that don't even have the tax base to support themselves and lack jobs?

It's not like suburbs aren't sitting on financial bombs either.

I would be more concerned about Climate Change. No amount of money will help.

Never allowing the forest to burn, which is a part of its natural cycle, is a form a drastic climate change for the forest. Proper management of the forest means selecting a time to do these burns. If we don't select a time, mother nature will select one for us. Yes, global temperature rise is real, and could potentially have had some effect on the fire. Completely disrupting the natural cycle of the forest is a much…

These fires are mostly burning chaparral, not forest. Better forest management is a good idea in general but not relevant to this article.

California has a long history of failed forest management. At what point will the voters say enough is enough? But they keep electing the same people. https://www.npr.org/2021/06/25/1010382535/gavin-newsom-misle...

Severe drought brought on my climate change is not going to be fixed by “forest management.” There is no forest around any of these fires.

I lived through another major wildfire in SoCal and the organization that provided the best support was the California Community Foundation: https://www.charitynavigator.org/ein/953510055 I’d wait until the smoke settles (because the CCF focuses on less well-off communities than Altadena or the Palisades) but donating to their wildfire relief efforts does a lot of good regardless. They frequently give grants to the l…

I would second this and say donate today. Focusing on who has money and who doesn’t today is really not a good policy. It is a generalization that is bound to misclassify some old ladies on a fixed income (my mom has one sleeping on her couch because of this). People who lost their homes and all their possessions yesterday and today may not be as wealthy as they were 24 hours ago.

> With the fires still largely unconfined, and no sign of letup from the winds spreading the blazes, the loss of JPL is looking increasingly likely. This is unsourced conjecture. If JPL actually burned, it would be a tragedy, but there's nothing to suggest that a massive, fenced, landscaped facility with a fire station literally at its gate [1] is in any real danger.

We can look to the experience of Los Alamos National Labs during the Cerro Grande fire in 2000 to provide perspective.

> You can achieve the same result by paying them prevailing wage. This has the extra benefit of giving them some saved up money to start a new life when they get out, helping them avoid falling back into a life of crime to make ends meet. I don’t see how you can do this, because you turn punishment into privilege. If the way to firefighter pay is through a jail cell you create all kind of problems around perverse inc…

Nobody is stopping you from being a firefighter outside of jail.

Have you tried? Do you have your certs? Would you pass the physical? Background check?
