Things going "boom"

One thing that seems to be a characteristic of Americans, especially American men, is their love of loud noises and blowing shit up.

I share this odd fascination myself, although in the interest of honesty I must admit that it isn't to the extent of a lot of guys.  I like fireworks, and I can remember as a kid spending many hours messing with firecrackers, bottle rockets, Roman candles, and so on.  (For the record, yes, I still have all of my digits attached and in their original locations.)  I don't know if you heard about the mishap in San Diego back on the Fourth of July in 2012, where eighteen minutes worth of expensive fireworks all went off in about twenty seconds because of a computer screw-up.  It was caught on video (of course), and I think I've watched it maybe a dozen times.

Explosions never get old.  And for some people, they seem to be the answer to everything.

So I guess it's only natural, now that we're getting into hurricane season, that somebody inevitably comes up with the solution of stopping hurricanes by shooting something at them.  The first crew of rocket scientists who thought this would be a swell idea decided the best approach would be firing away at the hurricane with ordinary guns, neglecting two very important facts:
  1. Hurricanes, by definition, have extremely strong winds.
  2. If you fling something into an extremely strong wind, it can get flung back at you.
This prompted news agencies to diagram what could happen if you fire a gun into a hurricane:


So this brings "pissing into the wind" to an entirely new level.

Not to be outdone, another bunch of nimrods came up with an even better (i.e. more violent, with bigger explosions) solution; when a hurricane heads toward the U.S., you nuke the fucker.

I'm not making this up.  Apparently enough people were suggesting, seriously, that the way to deal with hurricanes was to detonate a nuclear bomb in the middle of them, that NOAA felt obliged to issue an official statement about why this would be a bad idea.

The person chosen to respond, probably by drawing the short straw, was staff meteorologist Chris Landsea.  Which brings up an important point; isn't "Landsea" the perfect name for a meteorologist?  I mean, with a surname like that, it's hard to think of what other field he could have gone into.  It reminds me of a dentist in my hometown when I was a kid, whose name was "Dr. Pulliam."  You have to wonder how many people end up in professions that match their names.  Like this guy:


And this candidate for District Attorney:


But I digress.

Anyhow, Chris Landsea was pretty unequivocal about using nukes to take out hurricanes.  "[A nuclear explosion] doesn't raise the barometric pressure after the shock has passed because barometric pressure in the atmosphere reflects the weight of the air above the ground," Landsea said.  "To change a Category 5 hurricane into a Category 2 hurricane, you would have to add about a half ton of air for each square meter inside the eye, or a total of a bit more than half a billion tons for a twenty-kilometer-radius eye.  It's difficult to envision a practical way of moving that much air around."

And that's not the only problem.  An even bigger deal is that hurricanes are way more powerful than nuclear weapons, if you consider the energy expenditure.  "The main difficulty with using explosives to modify hurricanes is the amount of energy required," Landsea said.  "A fully developed hurricane can release heat energy at a rate of 5 to 20 x 10^13 watts and converts less than ten per cent of the heat into the mechanical energy of the wind.  The heat release is equivalent to a ten-megaton nuclear bomb exploding every twenty minutes."

And that's not even taking into account that releasing lots of radioactive fallout into an enormous, rapidly moving windstorm is a catastrophically stupid idea.

So yeah, you can shout "'Murika!" all you want, but even a moderate hurricane could kick our asses.  It may not be a bad thing; a reality check about our actual place in the hierarchy of the natural world could remind us that we are, honestly, way less powerful than nature.  An object lesson that the folks who think we can tinker around with atmospheric carbon dioxide levels with impunity might want to keep in mind.

Apparently Landsea's statement generated another flurry of suggestions of nuking hurricanes as they develop, before they get superpowerful.  The general upshot is that when Landsea rained on their parade (as it were), these people shuffled their feet and said, "Awww, c'mon!  Can't we nuke anything?"  But NOAA was unequivocal on that point, too.  Nuking tropical depressions as they form wouldn't work not merely because only a small number of depressions become dangerous hurricanes, but because you're still dealing with an unpredictable natural force that isn't going to settle down just because you decided to bomb the shit out of it.

So there you are.  The latest, quintessentially American, suggestion for controlling the weather, as envisioned by people who failed ninth grade Earth Science.  As for me, the whole discussion has left me in the mood to blow stuff up.  At least vicariously.  Maybe I should go watch the wonderful video of the amazing (and real) "Barking Dog Reaction," since if I actually blow something up, my wife will probably object.  

That's the ticket.  Things going boom.  I like it.

Paranoia bombshell

The Question of the Day is:  At what point does a prominent figure go so completely off the rails that people stop believing him?  Or is there no lower threshold for credibility?

Interestingly enough, I'm not talking about Alex Jones, or even Rush Limbaugh, here.  Today's contribution to the Annals of What-the-Fuck comes from Mike Adams, the "Health Ranger," owner of Natural News.

Adams has made his name touting dubious nutrition tips and scaring the absolute shit out of people over the dangers of vaccines, but now has ventured into conspiracy paranoia of every type.  And yes, I know that some of the stuff on Natural News exists purely as clickbait, to push up the site's rankings in search engines, but it's hard to escape the conclusion that Adams himself thinks what he's saying is true.

Consider, for example, his take on the horrific explosions that happened last week in Tianjin, China.

Most people believe that the blasts were caused by poorly-stored volatile chemicals, an explanation that gains credence when you realize that Tianjin is a major industrial seaport, and Chinese safety standards are lax at best.  This is not to downplay the magnitude of the disaster; over a hundred people are known dead, and the chain reaction of explosions devastated a huge area in the city.  According to a BBC article on the explosions,
Before the explosions, several firefighters were already at the scene trying to control a blaze.  There have been suggestions that water sprayed on some of the chemicals could have led to the blasts.   Calcium carbide, known to be at the site, reacts with water to create the highly explosive acetylene. 
Chemical experts suggest an acetylene blast could then have detonated the other chemicals for a much larger blast. 
The China Earthquake Networks Centre said the initial explosion, in a city with a population of around 15 million, had a power equivalent to three tonnes of TNT detonating, while the second was the equivalent of 21 tonnes. 
The second was so big that satellites orbiting Earth picked it up as well.
But such measured, thoughtful reporting isn't good enough for people like Adams.

Nope.  He has to claim that the Tianjin explosions were carried out by American "space weapons," and that China and the United States are "already at war," because of China's devaluation of the yuan:
Chinese dissidents have told Natural News they have reason to believe the attack on Tianjin is a warning shot from the United States, which is terrified that China is on the verge of announcing its own gold-backed currency while declaring a fire sale on U.S. debt holdings. 
The actions would collapse the U.S. dollar and destroy the U.S. economy, sending the United States into economic freefall. The "Rod of God" weapon deployment by the U.S. Pentagon, we're told, was America's "shot across the bow" to send a powerful warning message to China while disguising the attack as a domestic chemical explosion.
What evidence does he have?  Apparently people saw helicopters in the air immediately before the blast occurred.  Also, the Chinese government is controlling the movement of tourists, requiring them to register their passport numbers and hotel accommodations with officials.  (Didn't they already?)

'nuff said.  The only possible explanation is that the United States is blowing up Chinese seaports using space weapons.  Because that's credible.

What's next?  Claiming that there's a ground war being fought entirely between groups of crisis actors?  After all, why wage an actual war when you can just trick all the sheeple with footage of fake battles and false flags?

Okay, maybe Adams really is pulling our legs, here.  Maybe he's entirely in it for the ad revenue, and is making shit up, Weekly World News-style, just to keep us coming back.  But if you read what he writes, he sounds as if he's entirely serious.

Which brings up the troubling question of how many of his readers believe all of this stuff.  Are there really that many folks out there who think that everything in the mainstream news is false?  Because the way Natural News links get passed around on social media can't just be explained by the "Hey, you'll never guess what Mike Adams is claiming today!" phenomenon.

I dunno.  I find the whole thing troubling.  Not that it's impossible that Adams himself is paranoid; paranoia is, unfortunately, an all too real manifestation of some psychiatric disorders.  But the fact that enough readers exist to keep Natural News in business scares the hell out of me.

Because if that many people actually believe that the United States is blowing up Chinese cities with ray guns from space, I'm ready to concede defeat on the skepticism and move on to writing fiction full time.  After all, if it works for Mike Adams, it can work for me.
