For context on why this region is burning so easily: the Landes and Médoc are huge, artificial pine forests created in the 19th century under Napoleon III to drain and reclaim what was considered an inhospitable wetland, where shepherds famously walked around on stilts. Pine resin and needle litter makes it exceptionally flammable, and being an uninterrupted monoculture on flat land it lacks natural barriers to stop the fire from advancing.
The main reason the forest is burning is global warming. There were 3 punishing heatwaves before the fire, it was just a matter of time.
A part of the Fontainebleau forest, much more north, no pine trees, went in smoke earlier. Forests are burning near Madrid.
It may make some people feel better to think that it is an isolated, local problem, but unfortunately global warming is the main culprit and we at least need to acknowledge it.

I don't think the person you're responding to was trying to deny global warming being a factor. I think they're just explaining why this fire is so bad compared to other fires we have seen in France before.
I know global warming plays a major role in this, but I still found it interesting to know why this fire seems so bad.
You may be absolutely right about the OP, I cannot know.
Still, I believe it is important to highlight the elephant in the room first.
For example to your point: "I still found it interesting to kmow why this fire seems so bad compared to [...] before", I think it is important to state: "because global warming is getting worse over time". Not because pine trees, which have been around for a long time, and have never burned so badly.

The pine forests have been there for centuries, so it being pine is no explanation at all for why it's burning so badly now.

You’re both right.
However OPs post is more useful than yours.
By now, everyone knows about climate change. But I assume most didn’t know the fact about the pine trees in this area.
Nowadays it’s much more about how we deal with climate change and not so much about the fact that there is human made climate change.

Well said!
The problem isn't who believes in global warming, the problem is a forest fire. It doesn't care if there are 0% or 100% believers. Moving the needle on that percentage has no effect on the problems we will face due to global warming.
Here and now it's possible for a small community or country to take actions that will help the next time there's a forest fire. Or a flood, or a drought, or a heat dome, or a blizzard where blizzards shouldn't be.
Such efforts should clearly be priority 1. A doctor dealing with a gunshot wound doesn't start by urging politicians to reduce crime rates, they start by stopping the bleeding.
> By now, everyone knows about climate change.
Not true, I have seen people deny it on HN recently.
And looking at other debates, yes it is necessary to reiterate the primary cause. Because centrists will absolutely use the lack of that reiteration to do the "well actually it is the pine trees" in two days.

"Aktchually, forests burn because wood is flammable" is not the "useful" fact you think it is.
Yes, pine is flammable. So what? Should we replace it with wood that doesn't burn? And grows on already very dry soil? Because what the "informative" OP hasn't told you is that pine growsso much there because other woods don't do as well.

Blaming everything on global warming is extremely dangerous. It fails to address many other reasons why we are experiencing fires and creates an easy to blame enemy and a sensation that there's nothing we can do.
We should really go way deeper than just blaming everything on an increase of temperatures, which nevertheless is actually happening.
We, locals, have been warning already for decades of the increase of fires due to an accumulation of reasons, which I have actually described already in another message down below but I can summarize here.
* Forest mass has actually increased a lot during the last decades, Spain has now around 50% more forest mass than in the 1970s.
* Part of the increased mass has to do with reforestation efforts done by governments happening since last half of last century, which basically planted many forests using pine varieties which grow very quickly but also burn quickly (Pines are biologically design to burn with their flammable design and dried needles, that's their feature).
* Historical local forest were composed of many varieties of trees, including oaks, holm oaks, poplar, which grow slowly, are way less prone to burn, and regrow again after a fire. Those varieties were never used in any reforestation efforts, which has resulted in many new forests being extremely prone to burn quickly
* Population has shifted enormously towards big cities, abandoning little villages where forests were part of their style of life. Lumber was part of their economical income, which resulted in continuous care of those forests and efforts in preservation. There are still some communities like that in some areas of Spain, and their forests have the lowest rate of wildfires in the whole country.
* Many techniques like firebreaks, counter-fires, low intensity burning to clear crop stubble, dry brush, and old vegetation to regenerate fresh grass for livestock and prepare fields are now forbidden, again increasing the risk and extension of wildfires
* Forest Grazing is also nowadays completely forbidden. Sheep used to roam everywhere in the country, consuming many burning-prone vegetation, reducing also the risk of wildfires.
But even despite all of that, countries like Spain for example, have nowadays the lowest proportion of burnt forest since the last 50 years.
> Blaming everything on global warming is extremely dangerous
I don't think it's blaming on global warming. Global warming is just making those problems a lot worse.
It is just the beginning, on average it will get worse every year. Every kilogram of CO2 we emit makes it worse, so it won't stop worsening until we reach zero emissions.
> a sensation that there's nothing we can do.
On the contrary, I think there too much we must do because of global warming. There is so much that we certainly won't be able to do it all, meaning that the situation will get "more complicated" anyway. The more we do, the more we preserve.
To make a comparison that stays in the theme: saying "we won't stop it so there is nothing we can do" is like saying "this burning tree is dead anyway, so there is no need to save the rest of the forest". The tree is dead, it won't come back. And we know for sure that many other trees will die. But we should fight to preserve as much as we can from the forest. The less we do, the more we lose. But we will lose a lot anyway, maybe just not everything (depending on how well we fight).
Hola!
While I think this is mostly correct, I don't think it's OK to downplay climate change as just a "blame target". These current and extreme wildfires result from hotter and drier conditions, too. That is a major reason. And yes, we can do something about it.
Also, I know that controlled burns, grazing and firebreaks are widely used today in Spain, they are not universally forbidden.
Sheep and slow growing trees of course don't get along well, you have to choose one or the other at least while the trees establish, which for oaks is measured in decades.
In Wales and Ireland we have the opposite problem, the sheep strip everything bare, the old trees die and the forests cannot regenerate.
And cats. Don't forget cats.

> Le sujet, c’est l’aridification du milieu. Pour revenir à cet incendie, ce n’est pas un problème de culture, mais de climat.
A bit of a distinction without a difference. The climate is not changing back, it's the new normal. In that climate, this particular kind of agriculture (huge pine monocultures) has become a problem.
It breaks my heart to say this, I've spent nearly all my childhood summers in my family's summer house down there. This year, I left just a few days before the evacuation order would have come.
It's going to be burning every year now and if we want to be safe there, the forest can't stay the same.
> The climate is not changing back, it's the new normal.
Climate won't get any "new normal" until we reach strictly zero emission.
As long as we emit CO2, climate will get worse. There is no new normal: every year it will get worse.
It doesn't invalidate your point though, that it cannot stay the same and we have to do something. I'm just nitpicking on the "new normal". There won't be a new normal until we stop emitting CO2, it will just get worse and worse.
To add to your point, it's also worthwhile to mention that there are stakeholders against solving the climate crisis of global warming (besides the usual suspects like producers of non-renewables like oil companies): some countries benefit from the climate change like the US and Mexico (they get higher agricultural yields IIRC) [0].

ETA: clarification
Agree about global warming.
However, Fontainebleau forest has many pine trees.
In fact there is an invasive caterpillar there that lives in pine trees https://en.wikipedia.org/wiki/Pine_processionary
The caterpillars are also a consequence of warming.
Can confirm from my own experience that Fontainebleau forest is partly pine forests (40% according to https://en.wikipedia.org/wiki/Forest_of_Fontainebleau#Fauna,...).
And it does burn, but here are the history of fire:
https://fr.wikipedia.org/wiki/Incendies_en_for%C3%AAt_de_Fon...
Notice how the last was worse by one or two orders of magnitude.
You can handwave all you want the this and the southwest forests are particularly flammable, but what you are pointing out are only "canaries in the coal mines": they are the first to burn, but other forests will follow suit if global warming continues.
>The main reason the forest is burning is global warming.
I get where you're coming from but I don't think this is helpful.
Everyone with any sense knows global warming will cause heatwaves and they increase the risk of fires, but nobody in France can do anything about it. Even if everyone in France would do everything they can to stop global warming starting tomorrow, it would change nothing. It wouldn't help even if they got all of the EU on board.
What the people of France can do is demand more resources for fire protection, build air conditioned locations for the poor and elderly, plant trees for shade and so on.
This can be done immediately and will actually help. It also engages everyone, even a climate denier can get onboard with fighting fires and having shelter for heat.
If we stop at "it's the global warming", the response is either apathy or policies. We should prioritize things that will help right now.

You are falling for the voting fallacy: "my vote had a miniscule effect on the final result, why should I vote?". The paradox is that at the end, if everyone thinks so, nobody votes.

Moreover, because the warming is global and the whole world needs to be part of the solution, we need all the governments of the world to agree to some universal plan of action. This is governments that have trouble agreeing on most things within their respective borders, let alone globally.
> A part of the Fontainebleau forest, much more north, no pine trees, went in smoke earlier. Forests are burning near Madrid.
Small correction, but Fontainebleau is a fairly mixed forest including 20-30% pine.
Small correction, but the area of the Fontainebleau forest where the main fire occurred doesn't have this balance : les Trois Pignons, as name says, has a much higher density of pine trees.
There’s also a significant amount of pretty sudden local warning in the North Atlantic region because of the sudden removal of sulphur emissions from ships a few years ago (thanks, IMO…).
And on top of that it’s El Niño.
Edit: Before anyone misconstrues what I'm saying: no, I'm not denying global warming. I'm just saying this is why this summer in particular was always likely to be a hot one in Europe.
And going forwards the sulphur thing has most likely caused a step change from temperatures in Europe before Covid, despite underlying warming continuing at the same rate
The current El Niño hasn't really had time to affect NW Europe yet, there's quite some lag there AIUI.
We have these fires in france since I was born in early 80s. As far as I remember we had them almost every year. Nothing new about it. Doesn't say that global warming doesn't exist. But to shut of any discussion because of global warming is just wrong
Absolutely not. I've spent nearly every summer in the last 30 years in that region and it never was like this; it also wasn't that warm.
Occasional fires, sure. But very clearly nothing approaching the current scale and frequency.
The last really big one in that region was in 2022; and there are currently not one but 2 parallel fires in the same forest.
Not shutting the discussion of course, but it's important to realise that in the early 80s, that was exceptional.
Now it will happen more and more every year, there is no stopping that trend.
Depending on the area that has always been the case, indeed.
In fact, in the most historically prone areas, the Mediterranean part of France, number of fires and surface area burnt have tended to decrease over time since the 1970s [1], which shows that being prepared works and this experience must now be used in more areas of the country.

I am also French, I am also born in the early 80s and I can't understand how someone like you could have such an asinine take. This isn't of the same magnitude. Get out of "vibes" and burying your head in the sand and look at the total surface burnt, look at water levels in nappes phréatiques, look at temperature records and total days of canicule...

Regardless of your view on global warming, what's also vitally important is we don't do proper forest management anymore.
We used to thin the trees and clear the underbrush, which drastically reduces flammability and the ability for forest fires to rapidly spread.
But that's not seen as "environmentally friendly" these days.
Well, Denmark is I believe a country very big on being seen as "environmentally friendly" and they thin trees, generally to restore habitats and increase diversity of species. What gives?
The best way to prevent forest fires is to cut all the trees. No forest means no forest fire, right?
The problem (as always) is that it is complicated.
We are living in a mass extinction right now (orders of magnitudes faster than the one of the dinosaurs), mostly because of habitat loss. It has nothing to do with the climate (of course the climate is making it worse, but we screwed the biodiversity before that).
Is thinning the trees and clearing the underbrush good for the biodiversity? Probably not. Is it good to reduce flammability? Probably yes.
But I don't think it is fair to say that those who care about biodiversity are obviously wrong because preserving the biodiversity make forest more flammable. If you think like this, the solution is to go live in a bunker. Many people find that attractive (just look at how many dream about living in a bunker on mars), but I don't.
Don't put this on the environmentalists when the simple explanation isn't short term cost effective to do this. If you need to put some big blanket blame, then blame capitalism. If nothing else because it has so far stopped all effective measure to stop the climate crisis.

Might be time to revert it back to wetland.
Sounds like a good plan to me.
Probably a dozen reasons why we cannot that I am unaware of, but from my arm chair it looks good.
The water was likely redirected for agricultural purposes and the farmers won't/can't surrender it on top of drought, if it's anything like the US. Would be real cool if we could make investments like this though.

We could reintroduce malaria, that might be a nice return to nature
or even just re-planting different types of trees
From Le Monde:
> Some efforts have begun to diversify the Landes forest and to maintain or promote deciduous trees, particularly along the edges of plots. The major difficulty, according to foresters, is that very few species are able to grow in this region, where the sandy soil is very poor and very acidic (it is one of the poorest soils in Europe). Foresters describe the maritime pine as a "miracle species" in this regard.
> While other species can still grow, it is much more slowly and with greater difficulty. Radically transforming this vast forest, currently 80% dominated by maritime pines, therefore seems complicated, and there is also a significant economic stake involved in timber production in the region.

Pines are the survivalists of the forests. They can grow where nobody else can. What I mean is that this monoculture of Pine trees is not really a monoculture. Is an ecosystem.
The Landes are set over a lot of marine sand, so is not easy to create a firewall (mixing flammable and less flammable trees). The solution of just replacing pines by other species is not so easy technically. Pines are the only native tree that can trive in such poor soil.
