Et Si Une Tempête De Type Hypercyclone Frappait l’Océan Demain ?

Sympa

Imaginez un super ouragan, mais 10 fois plus puissant - on appelle ça un hypercyclone. Si une telle tempête frappait l'océan demain, les vents pourraient atteindre des vitesses allant jusqu'à 800 km/h, suffisamment puissants pour détruire des bâtiments et faire voler des navires comme des jouets. La tempête serait tellement intense qu'elle pourrait aspirer l'eau chaude de l'océan et l'envoyer très haut dans l'atmosphère, créant des pluies d'une abondance extrême et impactant le climat mondial. Les hypercyclones sont si puissants qu'ils pourraient même provoquer un refroidissement temporaire de la planète en bloquant la lumière du soleil avec les nuages qu'ils génèrent. Heureusement, ces tempêtes monstres sont principalement hypothétiques et ne se sont pas produites à notre époque moderne. Mais si jamais cela arrivait, nous serions confrontés à un climat vraiment fou !

00:00Our planet has experienced terrible floods, powerful tornadoes, destructive hurricanes.

00:07These dangerous natural disasters are familiar to us.

00:11But imagine this, winds howling through the atmosphere at about 800 km per hour

00:17and can persist for weeks.

00:19These insensitive winds could damage the ozone layer, making our Earth hostile to life.

00:25No, this is not a crazy dystopia produced by Netflix.

00:29These hypersyclones are real.

00:33A hypersyclone is a hypothetical tropical cyclone of extreme intensity, never seen on our land.

00:39To trigger a cyclone, the sea surface temperatures must reach about 50°C.

00:45Basically, hot enough to catch a blue steak.

00:48It's hard to imagine because it represents almost 22°C more than the highest oceanic temperature ever recorded.

00:56It was in Kuwait that the highest sea water temperature was recorded, in July 2020.

01:03What could cause such a phenomenal increase in temperature?

01:07The impact of a comet or a powerful asteroid?

01:10The eruption of a supervolcano?

01:12Or a major underwater eruption?

01:14There is even a theory that a series of hypersyclones

01:18could have accelerated the disappearance of non-ship dinosaurs after the famous asteroid impact.

01:24A difference in size between a hypersyclone and any other normal hurricane

01:29lies in the fact that a hypersyclone could rise to the top of the stratosphere,

01:34about 45 km above the surface of our planet.

01:38On their side, normal hurricanes only rise to the low stratosphere,

01:43about 10 km above the Earth.

01:46The difference would be dramatic, even catastrophic.

01:49But we will talk about it in more detail later.

01:53Hypersyclones could accompany an eruption of a speed of 370 km per hour.

01:59For comparison, the most powerful tropical cyclone ever recorded

02:03in terms of maximum wind support was Hurricane Patricia.

02:07At its peak, it reached a speed of 133 km per hour.

02:11This speed is insignificant compared to that of a hypersyclone.

02:15Can you imagine the impact that such a natural disaster could cause?

02:20If they form one day, these hypersyclones will also have a very long lifespan.

02:25They could rage for several weeks, or even more.

02:28Extremely low interior pressure would cause massive storms

02:32capable of covering entire continents.

02:34But there could also be hypersyclones less than 24 km in diameter.

02:39These formations would lose their strength quickly

02:42after drifting towards colder waters.

02:44But the surface temperature of the seas could remain very high

02:47for weeks after the passage of a hypersyclone,

02:49which could cause it again.

02:53As such a phenomenon would spread very widely in the stratosphere,

02:56it would even be possible that it would damage the ozone layer of the Earth.

03:00And this would have devastating consequences for life on our planet.

03:04The ozone layer absorbs some of the harmful sun's rays,

03:08preventing them from reaching the surface and people.

03:11I hope to never witness a hypersyclone of my own.

03:15Here is another potential disaster that could seriously harm the Earth

03:20and would come from the very activity of our sun.

03:22I want to talk about a huge solar eruption.

03:25Few natural disasters can cause so much devastation worldwide.

03:29A solar eruption would not destroy buildings like a tsunami or an earthquake.

03:34It would not be catastrophic in the same way as an asteroid or a supervolcano.

03:39But if the worst had to happen,

03:41it would destroy all the electronic infrastructure of our planet.

03:44To recover from the consequences of this disaster would cost thousands of billions of dollars.

03:51An incredibly powerful solar eruption could cause damage

03:55of unprecedented importance in communication systems,

03:58for medicine, banking systems and transportation.

04:01The Earth would run out of electricity for a long time,

04:04and people would not be able to restart the electrical networks, which were broken.

04:08Water supply systems would be out of service.

04:11There would be no more food in supermarkets.

04:16In 1859, inhabitants from different parts of the world woke up in the middle of the night

04:21because it was so bright outside that they thought it was already morning.

04:24The skies were lit with colorful aurora.

04:27It appeared even in regions where no one had ever seen before,

04:31in the Bahamas, Hawaii or Jamaica.

04:35The telegraphs were electrically charged, even those that were disconnected.

04:40Fires broke out in many regions.

04:43In other words, the consequences were already catastrophic,

04:46while technology almost did not exist.

04:49Imagine the avalanche of problems that a solar eruption could trigger today.

04:55Then there are the gamma surges.

04:58You will not encounter this type of radiation in your daily life.

05:01A gamma surge occurs when two neutron stars collide

05:05or when a massive star collapses.

05:07And gamma rays could become a serious danger to our planet.

05:11If such a phenomenon occurred near the Earth,

05:14it could probably carry all our ozone layer.

05:17And you already know how vital this layer is to us.

05:20In addition, gamma rays could create tropospheric ozone.

05:24This type of ozone could infiltrate the ocean.

05:27It is soluble in water.

05:29And this would lead to a massive extinction of marine life and plants.

05:34According to some theories,

05:36if a gamma-ray explosion occurred about 200 light-years from the Earth

05:40and these jets were directly directed towards us,

05:43our planet would be vaporized.

05:45If the distance was greater, but still in the Milky Way,

05:48the resulting radiation would sterilize all life on the exposed face of the Earth.

05:54Another planetary disaster we must talk about is called the super-eruption.

05:59The eruption of a supervolcano.

06:01Yellowstone Park is located at the top of one of them.

06:04The last massive eruption in this region occurred about 664,000 years ago.

06:10And the next eruption could be imminent.

06:13Fortunately for the moment,

06:15there is no evidence that the supervolcano is waking up

06:18or preparing an eruption for us.

06:20But if this happened,

06:21a massive column of lava and ash would rise in the air at a height of several kilometers.

06:26The volcano would continue to eject ashes for days and days.

06:33But the worst consequence of such an eruption for all living creatures

06:37would be the fall of ash.

06:39Buildings and trees would collapse under the weight of this very dense substance.

06:44In just a few days,

06:46a 3-meter layer of ash would cover a perimeter of about 80 km around the center of the eruption.

06:52Once the ashes had reached the stratosphere,

06:55temperatures would begin to drop all over the world.

06:58The eruption would most likely be rich in sulfur,

07:01an effective sun blocker.

07:03Thus, it would quickly be so cold that the summers would disappear,

07:07completely for several years.

07:09For animals, finding food and drinking water would be very difficult.

07:14The Earth could also cross a black hole,

07:18a region of space where gravity is so powerful that even light cannot escape it.

07:23For the moment, the black hole closest to us is about 1,500 light years away.

07:28So it seems that there is no need to worry.

07:30But have you ever heard of black holes?

07:33This is what worries you a little more.

07:35If such a black hole came to penetrate our solar system,

07:39the Earth would be condemned.

07:41Recently, and for the first time,

07:43astronomers have discovered a solitary black hole wandering in our galaxy.

07:47This space traveler is seven times more massive than the Sun

07:51and is now 5,200 light years away from us.

07:54Scientists have discovered black holes wandering in the past,

07:58but only in other galaxies.

08:00This is the first to appear in the Milky Way.

08:05Giant gulfs could also engulf entire communities.

08:09For example, when one of these gulfs appeared in the city of New York in the summer of 2022,

08:14it dragged a truck into the depths of the Earth.

08:17And it was not the only gulf to appear in this region.

08:20Residents have reported about 4,000 gulfs throughout the city

08:24between July 2021 and June 2022.

08:28This kind of problem is also very common in Florida.

08:31And it is generally of very great gravity.

08:34The gulf suddenly opens, engulfing everything and everyone nearby.

08:41There are gulfs all over the world.

08:43They are totally unpredictable and dig without anyone expecting it.

08:48Fortunately, experts know the causes today.

08:51In some regions, there are vast areas of underground water.

08:55During periods of drought, this water evaporates,

08:58which creates large, empty caves.

09:00After heavy rains, the surface above is likely to collapse,

09:04taking everything with it in a few minutes.
