What if everyone jumped in the ocean at once?
Because people are spread somewhat equally around the planet's spherical surface , if we all jumped in place, nothing much would happen — all our lift-offs and impacts would cancel each other out, resulting in zero net force on the Earth, according to work by physicist Rhett Allain.
In fact, most of the waters remain unexplored, uncharted and unseen by our eyes. It might be shocking to find out, but only 5% of the ocean has been explored and charted by humans. The rest, especially its depths, are still unknown.
You would need 37.5 million-billion gallons of water raise the water level across the entire planet by one inch.
These rising waters could displace hundreds of millions of people who live on small islands and in coastal regions. The report also found that most of the world's warm-water coral reefs are in danger of deadly bleaching events.
While thousands of climbers have successfully scaled Mount Everest, the highest point on Earth, only two people have descended to the planet's deepest point, the Challenger Deep in the Pacific Ocean's Mariana Trench.
Twenty-five percent of these individuals survived extreme impact in water at from 90 to 100 ft/sec, while only 4.9% survived a greater impact at any level.
More than 80 percent of the ocean has never been mapped, explored, or even seen by humans. A far greater percentage of the surfaces of the moon and the planet Mars has been mapped and studied than of our own ocean floor.
“The intense pressures in the deep ocean make it an extremely difficult environment to explore.” Although you don't notice it, the pressure of the air pushing down on your body at sea level is about 15 pounds per square inch. If you went up into space, above the Earth's atmosphere, the pressure would decrease to zero.
The Great Blue Hole, Belize
This massive ocean hole that is 984 feet wide and 410 feet deep is not only the world's deepest underwater sinkhole, but it is also one of the most dangerous.
If the ice keeps melting, global sea level could rise more than 20 feet. That would put a lot of coastlines under water. Whole islands could disappear! If the glacial ice covering Greenland were to melt, sea level would rise 20 feet (6 meters)! Credit: Center for Remote Sensing of Ice Sheets.
How high will the ocean be in 2030?
Global warming has already doubled or tripled the odds of extreme high water events over widespread areas of the U.S. coast. Widespread areas are likely to see storm surges on top of sea level rise reaching at least 4 feet above high tide by 2030, and 5 feet by 2050.
They projected 10 to 14 inches (25 to 35 centimeters) of rise on average for the East Coast, 14 to 18 inches (35 to 45 centimeters) for the Gulf Coast, and 4 to 8 inches (10 to 20 centimeters) for the West Coast.
Michigan, says globalization expert. A new book examining the forces shaping the future of global migration forecasts Michigan as the best place in the world to live in 2050.
It found that an estimated 4.3 million acres — an area nearly the size of Connecticut — will be underwater by 2050, including $35 billion worth of real estate. “Higher flood waters are reaching further inland, flooding properties and buildings that have never flooded before,” Climate Central researchers wrote.
Lots of human bodies end up in the sea, whether due to accidents, suicides or from being intentionally dumped there, but nobody really knows what happens to them, said Gail Anderson, a forensic entomologist at Simon Fraser University in Canada who led the unusual study.
Only three people have ever done that, and one was a U.S. Navy submariner. In the Pacific Ocean, somewhere between Guam and the Philippines, lies the Marianas Trench, also known as the Mariana Trench. At 35,814 feet below sea level, its bottom is called the Challenger Deep — the deepest point known on Earth.
In fact, 65% of our planet remains unexplored, most of which lies beneath the oceans. Literally anything could be down there, and we wouldn't know.
The water is like concrete at a height of around 100 meters or 300 feet. You may die in a split second because the water's surface tension is so strong.
The highest jump of a man – Laso Shaller (58,8 metres)
Since 2015 he has been the world record holder in cliffdiving. He jumped off 58,8 metres, which is few metres higher than the jump off a famous Leaning Tower in Pisa. During the jump Laso hit the water level at a speed exceeding 120 kph which is unbeliavable.
People usually survive falls from a height of 20-25 feet (6-8 meters), but above that, things get very deadly very fast. A study done in Paris in 2005 looked at 287 victims of falls, and found that falls from 8 stories (30 meters) or higher were 100% fatal.
Is there a hidden world in the ocean?
The hidden world under the sea: Scientists find 'parallel universe' of life INSIDE the basalt of the oceanic crust. A parallel universe of life exists hidden beneath our planet's ocean floors and could help us search for life on other planets, new research claims.
A piece of the Space Shuttle Challenger was recently found off the coast of Florida, NASA announced in a news release Thursday. The shuttle exploded 73 seconds after takeoff on Jan. 28, 1986.
It is also called the euphotic zone. Here there is enough light penetrating the water to support photosynthesis. Because photosynthesis occurs here, more than 90 percent of all marine life lives in the sunlit zone. The sunlit zones goes down about 600 feet.
After the Earth's surface had cooled to a temperature below the boiling point of water, rain began to fall—and continued to fall for centuries. As the water drained into the great hollows in the Earth's surface, the primeval ocean came into existence. The forces of gravity prevented the water from leaving the planet.
Interesting Facts About Earth : Around 50 percent of the US lies beneath the ocean. Shortpedia.
The northwestern Pacific Ocean is the least healthy of the world's oceans and the western Indian Ocean and eastern central Atlantic are the healthiest, according to a new assessment that gives the overall health of the Earth's oceans a barely passing grade of 67 out of 100.
The blue-ringed octopus' venom is 1,000 times more powerful than cyanide. This golf-ball sized powerhouse packs enough venom to kill 26 humans within minutes. It's no surprise that it's recognized as one of the most dangerous animals in the ocean.
Human activities are threatening the health of the world's oceans. More than 80 percent of marine pollution comes from land-based activities. From coral bleaching to sea level rise, entire marine ecosystems are rapidly changing.
A 1-foot rise in sea level swallows up more coastline than you think. For every 1 foot of vertical rise in sea level, 100 feet of shoreline is swallowed up if the slope is just 1% or more. That's a typical slope for most coastlines.
How much would sea level rise if all ice melted?
There is still some uncertainty about the full volume of glaciers and ice caps on Earth, but if all of them were to melt, global sea level would rise approximately 70 meters (approximately 230 feet), flooding every coastal city on the planet.
In 2020, scientists found evidence that warm water was indeed flowing across the base of the glacier, melting it from underneath. And then in 2021, a study showed the Thwaites Ice Shelf, which helps to stabilize the glacier and hold the ice back from flowing freely into the ocean, could shatter within five years.
AUnderstanding Global Warming of 1.5°C*
warming above pre-industrial levels, with a likely range of 0.8°C to 1.2°C. Global warming is likely to reach 1.5°C between 2030 and 2052 if it continues to increase at the current rate.
Collapse. According to a study of 7,800 ocean species, we are heading for a complete collapse of ocean life by 2048.
This will result in the complete evaporation of the oceans. The first three-dimensional climate model able to simulate the phenomenon predicts that liquid water will disappear on Earth in approximately one billion years, extending previous estimates by several hundred million years.
According to the World Economic Forum (opens in new tab), by 2100, Dhaka, Bangladesh (population 22.4 million); Lagos, Nigeria (population 15.3 million); and Bangkok, Thailand (population 9 million) could also be entirely drowned or have vast tracts of land underwater and unusable.
The world's largest potential source of sea level rise is the East Antarctic Ice Sheet (sometimes abbreviated as EAIS), which holds enough ice to raise global sea levels by 53.3 m (174 ft 10 in).
"There's no scenario that stops sea level rise in this century. We've got to deal with this indefinitely," says Michael Oppenheimer, a report author and climate scientist at Princeton University. Without action, rare, catastrophic storm surges will become common within 30 years, Oppenheimer says.
Climate change hazards like extreme heat, drought, wildfires, inland flooding, and coastal flooding are expected to impact millions of Americans by 2050. Vermont is the best state to move to avoid climate change. At-risk homeowners can minimize threats and save money by future-proofing their homes.
Historical and Projected Temperature Trends in Florida
In the next 20 years, average summer temperatures are projected to rise above 83°F under both moderate and high emissions scenarios.
Where will be the best place to live in the US with climate change?
Sacramento, California is the best place to live for climate change in 2022. 60% of the top 10 places to live in the U.S. for climate change are in California.
By 2100, large swaths of coastal land in Florida will be permanently submerged. In the shorter term, rising seas will increase the frequency and severity of coastal flooding. Statewide, three feet of flooding puts at risk: Future sea level depends on greenhouse gas emissions and atmospheric / oceanic processes.
At any rate, it could even be as early as 2050 when much of the Florida coastline would be underwater, depending on what the results of newer data might say. Flooding would affect Miami, Orlando, Tampa Bay and any other major center touching saltwater.
The total rise in sea level would be about 0.00012 of an inch, or less than 1/1000th of an inch. If everyone completely submerged themselves, this would double the answer to 0.00024 inches, which is still only about the width of a human hair.
The pressure from the water would push in on the person's body, causing any space that's filled with air to collapse. (The air would be compressed.) So, the lungs would collapse. At the same time, the pressure from the water would push water into the mouth, filling the lungs back up again with water instead of air.
1. The highest dive. On August 4, 2015 the Swiss diver of Brazilian descent, Lazaro "Laso" Schaller set the world record for diving from the platform, diving from 58.8m (higher than the Tower of Pisa, which measures "only" 56.71 m) and exceeding a speed of 120 km/h at his entry into the water.
Assuming you're in warm waters and wearing a wetsuit and life vest, you could potentially survive for as many as three to five days, at which point you'll most likely succumb to dehydration.
But reaching the lowest part of the ocean? Only three people have ever done that, and one was a U.S. Navy submariner. In the Pacific Ocean, somewhere between Guam and the Philippines, lies the Marianas Trench, also known as the Mariana Trench.
Even the hotties and hunks of the human race would likely have oblong-shaped bodies, great rolls of blubber and sleek bullet heads if Homo sapiens had adapted to the ocean like aquatic mammals did eons ago, Stanford University researchers said Monday.
Over vast periods of time, our primitive ocean formed. Water remained a gas until the Earth cooled below 212 degrees Fahrenheit . At this time, about 3.8 billion years ago, the water condensed into rain which filled the basins that we now know as our world ocean.
What is the deepest depth a human has gone?
Vescovo's trip to the Challenger Deep, at the southern end of the Pacific Ocean's Mariana Trench, back in May, was said to be the deepest manned sea dive ever recorded, at 10,927 meters (35,853 feet).
No they do not float, islands are the tops of underwater mountains. The base is at the bottom of the ocean.
A popular saying in Hawaii is to not turn your back to the ocean. That is because a large wave can come without warning knocking people off their feet and sweeping them into the ocean.
PADI (Professional Association of Diving Instructors) estimates that recreational divers can dive to a maximum depth of 130 feet. But they have a limited amount of time to do so before their health is jeopardized by the high water pressure and the inhalation of compressed air.
The maximum depth reached by anyone in a single breath is 702 feet (213.9 metres) and this record was set in 2007 by Herbert Nitsch. He also holds the record for the deepest dive without oxygen – reaching a depth of 831 feet (253.2 metres) but he sustained a brain injury as he was ascending.
A diver who descends 200 feet beneath the surface of the water breathing air from a scuba tank is taking a big risk. Safety regulations for recreational divers limit them to 130 feet. Even specially trained scientific divers are required to stay above 190 feet or they lose their certification.
This took more than 350 million years. There are humans (Bajau Laut- sea nomads) who can hold their breath for longer durations (up to some minutes) underwater. However, it is biologically impossible to evolve (or devolve) to live underwater in a short period.
José Salvador Alvarenga holds the record for the longest solo survival at sea. He was adrift for 438 days, and traveled over 6,700 miles.
Human kidneys can only make urine that is less salty than salt water. Therefore, to get rid of all the excess salt taken in by drinking seawater, you have to urinate more water than you drank. Eventually, you die of dehydration even as you become thirstier.
