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.
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.
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.
