Documentary on the new hybrid wolf/coyote species that has emerged in North America: the Coywolf

As our world wildly veers from one disaster to another, it's always a good idea to stop and smell the rapidly decaying roses once in a while, just to remind us that things could always be worse. Because, apparently, they could. From water tornadoes to the curiously titled 'icicles of death,' here are the 15 Most Dangerous Natural Phenomena In The World!

Tourists visiting the Breiðamerkurjökull glacier in Iceland were sent scrambling for high ground when a huge wave came crashing to shore after a huge chunk of ice from the glacier fell into the ocean.

Chunks of ice breaking from glaciers, known as 'calving' is a natural process, but a local guide said that breakaways are not usually so large or close to the shore.

Visitors to the glacier are warned beforehand to be prepared to run to high ground in such events.

Compilation of our most spectacular glacier calving and iceberg collapse videos! Huge chunks of ice (sometimes measuring more than 100 meters / 300 ft. in height over the water surface and hundreds of meters below) breaking off the glaciers and falling into the oceans can create tsunami-like waves, cause big icebergs to flip over or "shoot up". Glaciers and icebergs are melting in Greenland, Alaska, Argentina, Antarctica and all around the world – creating incredible spectacles for those lucky enough to be at the right place at the right time. More than 15 of these breathtaking glacier calving events are included in this montage. Of course all clips included are left with their original audio tracks; without music being added, you can listen to the cracking and melting of these ice giants.

Glacier calving, also known as ice calving, or iceberg calving, is the breaking of ice chunks from the edge of a glacier. It is the sudden release and breaking away of a mass of ice from a glacier, iceberg, ice front, ice shelf, or crevasse. The ice that breaks away can be classified as an iceberg, but may also be a growler, bergy bit, or a crevasse wall breakaway. The entry of the ice into the water causes large, and often hazardous waves. The waves formed in locations like Johns Hopkins Glacier can be so large that boats cannot approach closer than 3 kilometres. These events have become major tourist attractions. Many glaciers terminate at oceans or freshwater lakes which results naturally with the calving of large numbers of icebergs. Calving of Greenland's glaciers produce 12,000 to 15,000 icebergs each year alone

Compilation of the top five most spectacular glacier calving and iceberg collapse videos filmed at the Perito Moreno Glacier in Argentina until 2020! The Perito Moreno Glacier is famous for insane glacier wall collapses during the summer when large icebergs – often up to 250 feet (+75 meter) in height – are breaking off the glacier and collapsing into water of the Lago Argentino. A beautiful landscape, cracking sounds, large icebergs and sometimes even tsunami-like waves create overall stunning spectacles for all visitors!

The ice field of the Glacier Perito Moreno is the world's 3rd largest reserve of fresh water. The glacier is one of Argentina's most beautiful natural wonders – its colors and shapes of the ice remind of a piece of art of Gaudi. The glacier is about 5 km wide and has an average height of 74 m (240 ft). Despite most of the glaciers worldwide are retreating as a result of global warming and climate change, one of the very few glaciers that maintains in a state of equilibrium is the Perito Moreno Glacier as it continues to accumulate mass at a rate similar to that of its loss.

When warm summer air melts the surface of a glacier, the meltwater bores holes down through the ice. It makes its way all the way down to the bottom of the glacier where it runs between the ice and the glacier bed, and eventually shoots out in a plume at the glacier base and into the surrounding ocean.

The meltwater plume is lighter than the surrounding ocean water because it doesn't contain salt. So it rises toward the surface, mixing the warm ocean water upward in the process. The warm water then rubs up against the bottom of the glacier, causing even more of the glacier to melt. This often leads to calving – ice cracking and breaking off into large ice chunks (icebergs) – at the front end, or terminus of the glacier.

Glacier ice is weird. It’s solid. Solid things aren’t supposed to flow. But glacier ice flows like a liquid, and it does that without melting! How is this possible? I traveled to Mendenhall Glacier in Juneau, Alaska to find out.

A raging wildfire has broken out in the nearby forest. Endless billows of smoke are blackening the sky. But you notice something strange happening. The clouds of smoke start to rapidly spin and churn. They starts to absorb the fire and ash, turning into an intense, swirling blaze. Here's how to survive a fire tornado.

These natural disasters are disastrous whirlwinds induced by a fire often made up of flames or ash. Although rare, these fire devils may occur when intense rising heat and turbulent wind conditions meet to form a terrifying whirling current of air.

Crazy Aussie Runs Into Outback Tornado To Take Selfie

This is a compilation of some of the best extremely close-up footage of tornadoes I could find on the Internet. When looking at a tornado in the distance, you might not know what is going on around or even inside that tornado. From a distance, it might even look peaceful. But once you get up close and personal, tornadoes become extremely frightening. When you are close to or inside of a tornado, the true power of it shows. If this ever were to happen to you, hope that you are in a shelter of some kind...

Extreme up-close footage of tornado just north of Wray, CO by storm chaser and meteorologist, Reed Timmer. This footage was filmed on May 7, 2016.

Scientists place instruments inside a tornado to learn why one supercell produces tornadoes and another does not. Atmospheric Scientist Dr. Leigh Orf takes a different approach by growing storms that produce EF5 tornadoes in a supercomputer.

Rare EF5 tornadoes produce wind speeds estimated over 200 mph. Many people ignore tornado warnings because of too many false alarms. Others don’t respond because they don’t see a tornado.

The National Weather Service has the difficult task of trying to warn the public. But because we still don’t understand why one supercell produces a tornado and why another does not the NWS warns the majority of supercells. To reduce the “cried wolf effect” scientists are trying to figure out why one supercell produces tornadoes and why another does not.

Every Spring, scientists attempt to collect the data needed by deploying instruments inside a tornado and by scanning them with mobile radar as close as possible. Atmospheric scientist Dr. Leigh Orf is taking a different approach by successfully growing superstorms that produce EF5 tornadoes in a supercomputer. Using the Blue Waters supercomputer at the University of Illinois, Dr. Orf is able to simulate supercells at the highest resolution possible with today's hardware. This breakthrough technology has brought an alien anatomy to light. We now have the tools to see through the skin of the storm into an organized system of currents and what the supercomputer is telling us is that many of our previous theories were wrong. But, is this superstorm growing and living inside a computer a true representation of nature? One of the ways to help validate these incredible simulations is to compare them with actual storm footage.

Tornadoes are some of the most destructive forces of nature. Learn how tornadoes form, how they are rated, and the country where the most intense tornadoes occur.

Top 10 best tornado video countdown. Tornadoes manifest themselves in all sorts of shapes and sizes. Some are a wondrous bright white, others are dark horrific, monsters. Most are harmless grazing over rural farmland, others are worst case scenarios. I've been chasing tornadoes since 1999 and these are my top ten best tornado videos.

Tornado Sound:
The roar of a tornado sounds different depending on it's size, how close you are and what the tornado is striking. Ones I've heard over open fields often sound like powerful waterfalls. The bigger the tornado, the louder and deeper the rumble. Ones moving through trees get louder and can sound more like a jet engine. In town, where there are lots of homes and buildings an approaching tornado might sound like a freight train with the clickity-clack noises of airborne missiles and heavy debris slamming into your neighbors homes.

#10 on this countdown was an extremely close, stationary tornado twirling 50 yards in front of my vehicle.

#9 The El Reno Oklahoma on May 31, 2013 was the widest tornado ever recorded. Mobile doppler recorded 295 mph winds just above the surface as this tornado grew to a record breaking 2.6 miles wide. The tornado occurred over mostly rural farm. Because the most powerful winds did not strike any anchored structures, this tornado only received an EF3 rating.

#8 was a beautiful, white, shape-shifting EF4 tornado descending from a tight, high base near Alpena South Dakota on June 18, 2014.

#7 and # 6 belong to the Pilger Nebraska twin tornadoes that touched down on June 16, 2014.
Two tornadoes on the ground at the same time isn't common, however two almost identical powerful EF4's in close proximity is extremely rare.

# 5 occurred in Cedar County Nebraska on June 17, 2014. This violent tornado occurred over mostly open farm land and received a underrated EF3.

#4 touched down just south of Dodge City Kansas as two mesocyclones buckled into each other like gears. This storm was a long lived cyclic supercell responsible for dropping a dozen or more tornadoes on May 24, 2016. For most of this tornadoes life, it shared the stage with another nearby tornado and at one point three tornadoes were on the ground at the same time.

#3 was a long lived, extremely violent tornado touching down near Chapman Kansas or Abilene Kansas on May 25, 2016.
For ninety minutes this finely tuned machine was on the ground. Unbelievably, this breath taking EF4 did not claim any lives.

#2... If ever a thing haunts your dreams, It might resemble the remorseless Katie-Wynnewood Oklahoma tornado of May 9, 2016. In seconds this EF4 ripped entire roof off its walls and tossed its fragments a hundred meters into the air. The rest of the house demolished. Trees hovers above the ground while roof trusses and 2x4's whirl around the tornado like feathers and a man looses his life.

#1 takes us back south of Dodge City to that unprecedented day, May 24th, 2016. At least a dozen tornadoes touched down, but the first one was the ultimate beautiful tornado. For approximately 30 minutes this slow moving, perfect beauty presented the tornado of a lifetime up close! Well lit excellent conditions, with good roads provided a dream come true scenario for even the most dedicated veteran chasers.

In this video, I explain and demonstrate how fire sprinklers function. Three different types of sprinklers are showcased. With each activation, one of my fire alarm demonstration systems is set off. I hope this video can inform how fire sprinklers systems operate to control fires. Thanks for watching!

Whirlpools, how dangerous can they be? How deadly are they for human beings, how destructive are they for vessels? Can whirlpools suck ships, boats, or even barges in, or do they pose a danger only for human beings who fall into them?
In these shots you can see how the rafter Steve Fisher got sucked in by a powerful current that the athlete had the bad luck to encounter when descending the Congo River as part of a Red Bull-sponsored competition. Fisher, a world-class athlete, had a run in with the mighty rapids of this African river, yet this was not among the most dangerous whirlpools that exist on our planet, and far from the most dangerous whirlpools that are theoretically possible! Don’t try at home what one of the world’s top rafting pros barely managed to escape from. And that was even with the help of others…
There are whirlpools much more dangerous than along the Congo River! Some of these vortexes in the water pose a threat not only to people but even heavier objects.

A boat?.. A yacht?.. A ship?.. A barge?.. Even giant vessels can face destruction if any of them, separately or together, are sucked into one of these real aquatic monsters!
But let’s start by taking a look at whirlpools themselves. At what they are, how they arise, and what real danger and destructive force they pose.

How Do Whirlpools Form (Science for Kids)

Just outside the Marine Bay Sands Shopping Centre in Singapore the Whirlpool swirls that water down to the lower level pool where the Sampans sail. Quite a few people were rolling coins down with the aim to get the coin into the central hole. The Whirlpool is actually a whispering wall too as when you lean a bit closer to the rail you can here people talking from over the other side. True! Try it when you visit there!

This whirlpool lasted a lot longer because of a thing blocking most of the drain.

How to Swim in Rough Conditions
It's windy and raining time to postpone the triathlon? Not likely. Sooner or later, you're going to be swimming in rough water. But don't fret: An ability to manage waves can ultimately be an advantage. If you're adept at battling waves, it could be a significant upper hand against less wave-resilient opponents. And, if you ever need to breaststroke away from a shipwreck, a healthy ability to navigate stormy seas could end up being a real lifesaver.
To start, you're going to need to know how to breathe. In the open water, however, an incorrect breathing style could quickly leave you with a stomach full of salt water. That's why open water swimmers need to coordinate breathing with the conditions. If waves are coming in from your right, breathe left. If blinding sun is coming in from your left, breathe right. This might be trickier than you think, especially if you've spent years in the pool breathing to only one side. Before you tackle rough water, go to a pool and swim a few laps while breathing only on the side that you find least comfortable [source: Murphy]. In rough weather, waves, wind and spray also mean that you'll have less of a window in which to pull in air -- so be sure to make every breath count. Right before surfacing, exhale all of the air in your lungs. That way, when you come up for air, you'll be able to breathe in more quickly.
Sometimes, instead of battling the waves, it pays to swim under them. If you get hit by a particularly hard wave, you may be forced to dog paddle to recover, wasting valuable energy in the process. By ducking under those waves like a dolphin, you'll avoid getting jostled often and your rough water swims will be much less frustrating [source: Keppeler]. If a wave is relatively small, save energy by simply hopping over it. Or, if it's small enough that you can just crash through it, simply turn sideways and hit the wave with your hip or shoulder. Do it properly, and the wave will simply pass around you.
Warming up before a swim is a good idea in all weather conditions, but it's especially important in rough seas. Get in, splash around, try a test sighting anything that will give you a good idea of water temperature, visibility and current. That way, long before the starting gun goes off, you'll be able to adjust your goggles, suit and swim plan as necessary.
