"Even at their worst, the sun's flares are not physically capable of destroying Earth," NASA says.

HAARP, OTOH... 🤗

(See, it's always what these folks *don't* tell you..)

[Montana_Sam]

The 1859 Carrington Event was powerful.

When we get hit with another of that magnitude, we'll have a serious problem.

[ProtectOurFreedom]

But there is no need to worry; so-called "killer flares" do not exist and although solar flares have the potential to significantly disrupt the technological world, they don't contain enough energy to do any lasting damage to Earth itself.

Oh yeah? Many others do not agree with that blithe dismissal.

Evidence for a Solar Flare Cause of the Pleistocene Mass Extinction
Published online by Cambridge University Press
18 July 2016

The hypothesis is presented that an abrupt rise in atmospheric radiocarbon concentration evident in the Cariaco Basin varve record at 12,837 ± 10 cal yr BP, contemporaneous with the Rancholabrean termination, may have been produced by a super-sized solar proton event (SPE) having a fluence of ~1.3 × 1011 protons/cm2. A SPE of this magnitude would have been large enough to deliver a lethal radiation dose of at least 3–6 Sv to the Earth's surface, and hence could have been a principal cause of the final termination of the Pleistocene megafauna and several genera of smaller mammals and birds. The event time-correlates with a large-magnitude acidity spike found at 1708.65 m in the GISP2 Greenland ice record, which is associated with high NO-3 ion concentrations and a rapid rise in 10Be deposition rate, all of which are indicators of a sudden cosmicray influx. The depletion of nitrate ions within this acidic ice layer suggests that the snowpack surface at that time was exposed to intense UV for a prolonged period, which is consistent with a temporary destruction of the polar ozone layer by solar cosmic rays. The acidity event also coincides with a large-magnitude, abrupt climatic excursion and is associated with elevated ammonium ion concentrations, an indicator of global fires.

Younger Dryas “black mats” and the Rancholabrean termination in North America
By C. Vance Haynes, Jr
May 6, 2008

Of the 97 geoarchaeological sites of this study that bridge the Pleistocene-Holocene transition (last deglaciation), approximately two thirds have a black organic-rich layer or “black mat” in the form of mollic paleosols, aquolls, diatomites, or algal mats with radiocarbon ages suggesting they are stratigraphic manifestations of the Younger Dryas cooling episode 10,900 B.P. to 9,800 B.P. (radiocarbon years). This layer or mat covers the Clovis-age landscape or surface on which the last remnants of the terminal Pleistocene megafauna are recorded. Stratigraphically and chronologically the extinction appears to have been catastrophic, seemingly too sudden and extensive for either human predation or climate change to have been the primary cause. This sudden Rancholabrean termination at 10,900 ± 50 B.P. appears to have coincided with the sudden climatic switch from Allerød warming to Younger Dryas cooling. Recent evidence for extraterrestrial impact, although not yet compelling, needs further testing because a remarkable major perturbation occurred at 10,900 B.P. that needs to be explained.

X-class solar flare? My first thought was “What’s Elon up to now?”

“ Even at their worst, the sun's flares are not physically capable of destroying Earth," NASA says.”

But, could it fry our communication systems?

[Organic Panic]

But it is our carbon footprint that controls the climate....

So he says,

Even if something has a .0000001% chance of happening, if done often enough, it’ll happen.

Eventually the sun will cook, and then eat us, assuming it doesn’t have some sort of weird flare that we never thought possible which wipes us out, or some anomoly where its output suddenly drops and we all freeze to death while worrying about global warming: https://en.wikipedia.org/wiki/Maunder_Minimum

Of course we may be wiped out before then by a big rock from space that hits us, depending on what random collisions occure in the Astriod belt and what is hurled our way: https://en.wikipedia.org/wiki/Chicxulub_crater

Meantime, narasistic and self important man will pretend that his plastic shopping bag or use of a car will end the planet.

[George J. Jetso]

Of course we’re all gonna die again.

Cycle 25 has been wild so far and promises to be one of the best in recent cycles for Amateur Radios Ops. Outages are never fun but it keeps it interesting.

[Bishop_Malachi]

What!?! No picture of Ric Flair!?!

[minnesota_bound]

Could easily have been gamma rays and all life in that area wiped out or everyone made into a Hulk...

I read a science fiction story (the gist) of a boy who could see the future. His predictions came true and one day he said that all troubles would be over. People around the world were overjoyed. What he did not tell them was he saw that the sun was to go nova.

[Reily]

Lots of charged particles will hit the atmosphere creating more clouds and likely more cooling.
