Ever heard of ice fog? In Budapest, in 2015, thick fog suddenly rolled in, but it wasn't your ordinary fog - it was icy. The temperature plummeted, and everything it touched turned to ice, even poor unsuspecting trees and animals. It's like a warning sign from Mother Nature herself, reminding us travelers to tread carefully 'cause you never know what crazy stuff she's got up her sleeve. Oh, and speaking of nature's surprises, ever heard of earthquake lights and unexplained ground vibrations? They're like the Earth's way of saying, "Hey, I'm shaking things up a bit!" Just when you thought you had nature all figured out, it hits you with these wild phenomena!

FunTranscript
00:00 In December 2014, an entire district in Budapest got covered with ice crystals.
00:06 The trees in the area couldn't handle the pressure from the ice and they started toppling
00:10 over.
00:11 It was a spooky occurrence called ice fog.
00:14 When it happens, the temperature drops significantly, freezing everything around, like Dementors
00:19 did in the Harry Potter movies.
00:22 All thanks to a temperature flip-flop.
00:24 It not only messes with what you can see, but also creates ghostly pillars and halos
00:30 that glow in the dark.
00:32 Ice fog is made up of tiny ice crystals.
00:35 When it's below 14 degrees Fahrenheit, water droplets in the air freeze and turn into ice
00:40 crystals.
00:41 Until then, they stay liquid unless they find something to freeze onto.
00:46 Ice fog usually forms in chilly parts of the world like the Arctic or Antarctic.
00:51 Budapest was a plot twist.
00:54 Hot moist gases from vehicles and planes can also create ice fog.
00:58 One plane takes off on a cold day and boom!
01:01 There's so much ice fog that the next plane can't see a thing.
01:05 That sometimes happens.
01:07 It's not the same as diamond dust which is when sparse ice crystals fall from a clear
01:12 sky.
01:13 It forms when the humidity is super high, nearly 100%, and the air temperature drops
01:18 way below 32 degrees Fahrenheit.
01:22 This creates ice crystals in the air, and they end up settling on different surfaces.
01:26 Interestingly, early settlers thought these ice crystals could get into their lungs and
01:31 cause some trouble.
01:33 There are many other interesting ice formations such as rabbit ice.
01:37 It occurs when the air is chilly but the ground is yet to embrace the frosty vibes.
01:42 The sap inside plant stems expands as it freezes, making the stems crack open.
01:48 Once it happens, liquid slips out, meets the frosty air, and turns into thin layers of
01:53 ice, creating beautiful petal or ribbon-like formations.
02:01 Earthquake lights are another weird and unique phenomenon.
02:04 When a powerful magnitude 8.1 earthquake hit Mexico in 2017, images of strange green and
02:11 blue lights in the sky flooded social media.
02:14 These so-called Mexico earthquake lights added another layer of mystery.
02:20 Similar to ball lightning, earthquake lights are pretty rare.
02:23 Fascinating, but tough for scientists to figure out.
02:27 What makes it tricky is that the instances of luminosity around earthquakes don't all
02:32 look the same.
02:33 There are both theories and myths about this thing.
02:37 The lights can appear in many different shapes, forms, and colors.
02:41 Digging into history, researchers examined 65 accounts of these lights dating back to
02:46 1600 CE.
02:48 For instance, on November 12, 1988, people reported a bright purple-pink globe of light
02:54 along the St. Lawrence River in Quebec, just 11 days before a powerful quake.
03:01 In Pisco, Peru, the lights took the form of bright flashes captured on security cameras
03:06 before an 8.0 magnitude earthquake in 2007.
03:11 And before a 2009 earthquake in L'Aquila, Italy, folks saw 4-inch flames of light flickering
03:17 above a stone street.
03:19 Yet, there are still debates about whether earthquake lights are real or not.
03:23 The U.S. Geological Survey is a bit cautious, not sure whether individual reports of unusual
03:30 lighting around the time and place of an earthquake truly represent earthquake lights.
03:38 In one study, scientists theorized that these lights were caused by electric charges activated
03:43 in specific types of rocks during seismic activity, like turning on a battery in Earth's
03:49 crust.
03:50 Some rocks, such as basalt and gabbro, have tiny crystal defects.
03:54 They might release electrical charges into the air.
03:58 Researchers estimated that the conditions needed for the creation of these lights existed
04:02 in less than 0.5% of earthquakes worldwide.
04:07 It could explain their rarity.
04:09 They also noted that the lights tend to show up more often before or during quakes than
04:15 afterward.
04:16 An earlier study suggested that tectonic stress could create a piezoelectric effect, where
04:22 quartz-bearing rocks produce strong electric fields when compressed.
04:27 Yet, studying earthquake lights is tough because they're unpredictable and short-lived.
04:35 Time to talk about a sudden ring around the moon or sun.
04:39 You're walking with a friend and suddenly see this sun halo.
04:43 It's nature's warning.
04:45 A snow or rainstorm is coming.
04:48 These halos form when bazillions of tiny ice crystals and clouds refract sunlight.
04:54 Resist the temptation to stare at this wonder directly.
04:57 It can damage your eyes.
04:59 Grab sunglasses and then admire it for about 40 minutes.
05:04 Nature sends other early warnings too.
05:07 If the sea mysteriously recedes, showing coral and fish, a tsunami might be on the way.
05:13 Watch out for rip currents on the beach.
05:15 Sharks might be fleeing a storm if they come unusually close.
05:20 Feeling your hair stand on end and jewelry buzzing?
05:23 Lightning might strike nearby.
05:25 Seek shelter.
05:26 Avalanches, green storms, and lakes near volcanoes are all potential dangers.
05:32 Cross seas are extremely dangerous.
05:34 Cave exploration during a full moon might cost you your life.
05:38 If the ocean turns reddish-brown, avoid swimming.
05:41 There might be toxic algae in the water.
05:44 Animals sense disasters too.
05:46 If they act strangely, pay attention.
05:51 There's a fascinating blue glow around Matsu Islands on summer nights.
05:56 It's caused by tiny glowing creatures.
06:00 Tourists love watching this beautiful spectacle, but there's a downside.
06:04 It's toxic and getting bigger each year, as revealed by a study.
06:09 Despite its romantic appearance, this phenomenon is harmful.
06:13 A team of oceanographers used satellite data to track its growth over 19 years.
06:19 After analyzing almost a thousand satellite images, they concluded that it was expanding
06:24 into deeper waters.
06:26 Unfortunately, this expansion poses a threat to marine life.
06:30 The bloom of blue tears can poison fish and sea turtles and even affect human health.
06:36 While dinoflagellates themselves aren't toxic, their food, toxic algae, releases harmful
06:42 chemicals into the water.
06:44 This process depletes oxygen, endangering marine animals.
06:49 The main cause is unclear, but pollution from agriculture down the Yangtze River seems to
06:55 play a crucial role.
06:58 Agricultural runoff introduces nutrients that fuel the bloom.
07:02 During the construction of the Three Gorges Dam project, the bloom's size reduced when
07:06 the river's flow decreased.
07:09 After the dam was finished and the river started flowing strongly again, the bloom resumed
07:13 its growth.
07:14 The team predicts that blue tears will keep expanding, posing an ongoing threat to marine
07:19 life and creating more vividly glowing waters.
07:26 A katabatic wind or drainage wind happens when dense cold air descends from a higher
07:31 elevation down a slope due to gravity.
07:35 These winds can be powerful, sometimes reaching hurricane speeds, but rarely.
07:39 Unlike all downslope winds, katabatic winds like the bora in the Adriatic or Santa Ana
07:45 in California originate from cooling air on elevated surfaces like plateaus or mountains.
07:52 As the air descends, it warms up.
07:54 Its temperature depends on the source region.
07:57 In Antarctica, katabatic winds are crucial in shaping wind fields.
08:02 In regions such as Greenland and Antarctica, these winds can become extremely intense,
08:08 reaching hurricane force.
08:10 They contribute to unique phenomena such as the McMurdo Dry Valleys in Antarctica, and
08:15 are associated with such dangers as willow walls in the Fugien Archipelago and Alaska.
08:24 St. Elmo's Fire is a natural phenomenon worth mentioning.
08:28 It happens during thunderstorms or volcanic eruptions when there's a strong electric
08:32 field around the area.
08:35 It creates a bluish or violet glow around such things as ship masts, airplane edges,
08:40 or sharp objects.
08:42 This glow is caused by ionized air molecules and is more noticeable in low-light conditions.
08:48 The glow is a form of plasma and it happens when the electric field around an object causes
08:52 the ionization of air molecules.
08:55 This can occur during thunderstorms because there are high voltage differences between
08:59 clouds and the ground.
09:01 Light points make it easier for St. Elmo's Fire to occur because the electric field is
09:06 more concentrated in those areas.
09:09 The colors you see, blue or violet, come from the fluorescence of nitrogen and oxygen in
09:14 Earth's atmosphere, similar to how neon lights work but with different gases.
09:19 From ancient Greece to 15th century China, this phenomenon has been seen throughout history.
09:28 That's it for today!
