A case study: Analysis of the Portuguese forest fires.

Fires of large dimension destroy forests, harvests and housing objects. Apart from that combustion products and burned surfaces become large ecological problems. Very often fires emerge simultaneously on different locations of a region so a question could be asked if they always have been a consequence of negligence, pyromania, high temperatures or maybe there has been some other cause.
This paper is an attempt of establishing the possible connection between forest fires that numerous satellites registered and activities happening on the Sun immediately before fires ignite. Fires emerged on relatively large areas from Portugal and Spain on August 2005, as well as on other regions of Europe.
The cases that have been analyzed show that, in every concrete situation, an emission of strong electromagnetic and thermal corpuscular energy from highly energetic regions that were in geo-effective position had preceded the fires. Such emissions have, usually, very high energy and high speeds of particles and come from coronary holes that also have been either in the very structure or in the immediate closeness of the geo-effective position.
It should also be noted that the solar wind directed towards the Earth becomes weaker with deeper penetration towards the topographic surface. However, the results presented in this paper suggest that, there is a strong causality relationship between solar activity and the ignition of these forest fires taking place in South-western Europe.

QUACK, QUACK, QUACK!
It’s possible, yes. It’s not highly likely.
Coronal Mass Ejecta have caused many problems with the magnetosphere of the earth, caused massive EMP on electrical systems (taking down power systems and generators in hydro plants in the past). Causing fires is a bit more difficult, but a solar flare could conceivably hit us. CMEs throw out more matter, in general than a flare though.
They spelt it wrong. It's corpsuckles.
When people use a term like "thermal corpuscular energy", they are receiving messages...
“Solar activity as a possible cause of large forest fires”
What a bunch of crap!!!
All they are claiming is there is a correlation between forest fire outbreaks and solar activity. Whatever mechanism/indirect effects that is causing this correlation they don't speculate on.
As for thermal corpuscular energy, this study is from Portugal so there might be a translation problem.
Solar wind seems especially strong today
Maybe the solar flares cause more lightning....which causes more fires????
Well, all true. Though, having sat in the sun for many hours at a time observing sun spots, I can say that is sufficient to get you sunburn :)
If there is a higher solar activity, then we can easily deduce more atmospheric activities, thus more storms, and from that more lightning strikes, more lightning strikes cause more fires.
This isn’t some wild logic, it’s a fact.
The idea of “global warming” isn’t a BAD idea. The idea that it is caused by people is what is a BAD idea.
Global warming, as well as global cooling takes place on a cyclical basis, as seasons change, and as the Earth itself tilts.
For instance.... Earth has a polar axis tilt. That imaginary line going through the center of the earth from the north pole to the south pole. This is why we see Polaris as our “North Star” right now.
The “wobble” present on the planet will move the North Pole to point at a different place in the sky over time, say, about 25000 years from now, a different star may serve as the north star.
This also serves to change the seasons on the planet as well. Currently our Summer in the northern hemisphere is in the “summer months” or June-August, while in the southern hemisphere this is winter time.
So, ice ages tend to occur when the poles change positions (pointing to another place in the sky) which causes the earth to tilt in a different way than it is now. (At least that’s one theory).
Another theory is that the sun, which is actually traveling in a circle around the outer edge of the Milky Way Galaxy passes periodically through large clouds of dust and debris in the galaxy. This could obscure the sun to a greater or lesser extent causing it to become much colder on the planet than it currently is now.
Man made global warming is really nothing more than a bunch of screaming nonsense, by people who do not particularly understand astrophysics, the solar system, or anything about astronomy and go from bad human memory of “how warm it used to be back when I was kid” - or listen to BAD DATA and make claims that “so much CO2 has caused this problem”... when in fact, they can’t show a “problem”, nor results of so-called Man-made global warming.
What they fail to take into account is the very fact that the SUN is what drives our environment, and without it, there’d be no life at all here. Not even microbes. With the sun, and our cycles we have seasons, and we have cold, and we have heat and we have life.
great picture. especially like the look in the cats eyes
looks like he’s thinking “500 million cat owners in the world, and I get this nutbar”
You obviously have observed reality and know when something is being presented in a false manner for political reasons.
I have no arguments with our last post and it was appreciated.
Large forest fire outbreaks occur when the forest gets too dry.
This is due to solar radiation.
If you take an oily rag, and let it get a little sunlight, it ignites by itself.
A tiny micrometeorite (which we are pelted with constantly) can ignite a forest.
When one considers that we are inside the burning corona of the sun, and that clouds are our major protection, it is a miracle we don’t have more fires.
What political reasons? The study doesn't mention global warming at all. If anything, if this study has any merit it would be a plus to the skeptical side of the global warming issue.
Interestingly, here's a study confirming this
Recordings of potential gradient and air-earth current in fair-weather conditions were made at high-elevation mountain stations; the latter were generally above the vertical-mixing layer and not disturbed by local sources. Both electrical quantities increased significantly from the day of appearance of a solar flare (or a maximum incidence of flares) till the fourth day after the event. Peak potential gradient and air-earth current exceed the normal levels measured during quiet-sun conditions by 5060% in terms of averages.............................We may conclude from these results that the total potential between the ground and the upper atmosphere increases for several days after solar flares.
So this link between solar activity & forest fires might not be so crazy after all
The idea of global warming isnt a BAD idea. The idea that it is caused by people is what is a BAD idea. Global warming, as well as global cooling takes place on a cyclical basis, as seasons change, and as the Earth itself tilts....What they fail to take into account is the very fact that the SUN is what drives our environment,
I know Global warming is a scam, my point (Note: there is no GW mentioned in this study) before this thread kind of went off the deep end was that if this study turns out to have something to it and the sun (no matter how indirectly) can effect forest fires then it is ludicrous to believe the sun can't have any effect on the climate as a whole like the alarmist tell us.
If it was not for solar activity, the Earth would be nothing but a ball of ice.
With an increase of solar irradiation, some areas of the planet will obtain more rain, and other areas will become drier as a result.
If it rains in one area, then there is not much left for another area downwind. That is why mountains get lots of rain, and deserts on the downwind side receive very little moisture.
Actually, the thread didn’t really go off the deepend. There is another thread, along the same lines going on now. It was suggested in that article that “cosmic rays” don’t change with the solar cycle, and “thus” we can’t say that the sun effects the environment.
This is blatantly incorrect, bad logic and so on. Someone merely mentioned that thread at the beginning.
It all comes down to real science though - and global warming is something that DOES happen, but not based on man-made problems, rather based on the Sun itself. Because of this, these things are definitely connected.
Of course it’s not a cause. It may be a contributing factor. The headline writer needs to review the definition of “cause”.
NONSENSE! The sun has absolutely nothing to do with the warming of the planet!
In the Summer when the temperatures and solar influence is stronger, then we get more forest fires. It is hot and dry.
Of course the Sun can "cause" forest fires.
Apparently it did go off the deep end, all this study is about is the authors noted a correlation between solar activity & forest fires. Nothing more, nothing less. They don't link it to or even mention global warming in any way, pro or con.
It was I not the authors who linked it to the global warming issue by noting in the 1st post that if this study is true, then what the alarmist have been telling us about the sun having no effect on climate can not be true. Somehow that lead to tin-foil hats and some leftist political motivation that's just not there. Again, if anything, this study is a plus to the skeptical (the correct)side.
I haven’t been disagreeing with you. lol
