Engorged Pedipalps posted:I understand their concern but I don't understand how this wasn't a problem when forests were like 90 times more dense than they are now Because biomass density isn’t static nor all the same. A healthy forest with full understory, trees of many ages, and lots of new growth will burn differently than a forest with most of the biomass in large old canopy trees. The old trees when they burn will burn hotter because more of their biomass is dry wood. Versus a healthy forest where a lot of the biomass is in green new growth that won’t burn as hot.

Here's another article about old growth forest. They aren't more tree dense, just more species dense. https://phys.org/news/2019-07-old-growth-forest-valuable-biodiversity-refuge.html

Cold on a Cob posted:listening to a pretty good podcast about the wildfires in alberta right now We're going to experience some incredible things folks, things that have probably never been experienced before. People come to me and tell me that's hard to believe, it can't be, and I tell 'em, listen, I tell 'em folks, these experiences, they're gonna be brand new. Fire tornados hundreds of feet tall, things you have to see to believe. I've experienced them, I've probably experienced them before and better than anyone else. Believe me folks, these experiences, your going to experience these things like nobody has before.

Engorged Pedipalps posted:I hate to be that guy, but wildfires are normal and fine Yeah, I hate to be that guy too but I haven't had my second cup of coffee yet so... Other posters have covered this but it's very much biome-specific. The native soil in tropical rainforests is heavily leached so there's not much in the way of nutrients left in it except iron. The nutrients are all locked up in the vegetation and any dead tree that hits the forest floor is quickly decomposed while the surrounding vegetation grabs all the nutrients it can. This type of forest is not adapted to fire as a tertiary state and large burnt areas = bad. There were reports last year of tropical rainforests on fire that haven't burnt in the last million years. I'm not going to trawl Google Scholar for them though, see: second cup of coffee. Temperate forests otoh are adapted to fire. Lodgepole pine for example has a 20 year cycle producing increasingly resinous cones until at the end of the cycle they won't open and release their seeds until a quick hot understorey fire comes through the litter built up on the forest floor and burns the resin out of the cones allowing the seeds to fall out after the fire has passed and life continues. This assumes an old growth mixed species forest. "Weed" species like aspen don't burn well and mediate the intensity and extent of burns. They are also critical for the subsoil mycorrhizal (fungal) network that the trees, especially the juveniles, rely on for nutrients and even moisture. For many years foresters like other bioscience nerds have been brainpoisoned by the zero sum competition model of life so they removed weed species by dumping tonnes of glyphosate prior to re-planting a monoculture of pines. Unfortunately glyphosate also poisons fungi and appears to have nuked the mycorrhizal network required for healthy juvenile pines -> sickly, dying pines -> fat happy Mountain Pine beetles -> dead forests full of dryer-than-tinder (I am not kidding, the moisture content numbers coming out of the woods are in the "something's wrong with your instrument" range) explosively flammable dead standing trees. Coastal Douglas Fir are slightly different. A reasonably mature Doug Fir has a long straight trunk with no branches until quite a distance up from the forest floor and thick cork-like bark that chars instead of burns so understorey fires don't have ladder fuel to climb up and become crown fires. Crown fires are bad, ask California. We do get big burns every few hundred years or so, kind of like the big earthquakes that come along on a similar schedule. Last one on Vancouver Island was 1840 and burned everything on the east side of the mountains from Nanaimo to Comox. But the forest was adapted and regenerated quickly from surviving pockets and the locals grabbed their house boards and paddled across the Strait to visit relatives who weren't on fire and returned to erect new house posts when things stopped smoking and life continued its cycle. Now however big mature Doug Fir are limited to a few tree museums and the unusual extended summer drought (perfectly normal at 2 months long, but not so much at 4 months year after year) has caused a massive die-off of shallow-rooted Grand Fir which are standing dead in the forest with moisture contents that I used to think could only be achieved with a lumber kiln. But I dunno, I could be full of poo poo too. It wasn't that long ago I came to the realization that "It's the plants, stupid" and plants are weird and complicated compared to critters. And beneath the plants the fungus and bacteria. Regardless, none of these should be fed to the Goddess of Firenados. Increasingly it seems humanity has been fapping to porn instead of studying for the final exam. All we've got to show for our efforts are friction burns.

He never drove it anywhere and it took up so much of his driveway that he had to park his fleet of other ridiculous vehicles in the board of ed parking lot across the street. Very normal and acceptable behavior. did he get ticketed or were the local police too corrupt?

hmmm, the earth seemed (it was probably still bad) to have a long period of equilibrium with global human population under 1 billion people before exploiting fossil fuels became much of a thing, 200 years ago and things notably changed a lot since then. But who can say?
