What is the coldest it has ever been in Antarctica?
About minus 144°F, according to recent satellite measurements of the coldest known place on the planet.
Scientists recorded this extreme temperature on the ice sheet deep in the middle of Antarctica during the long, dark polar winter..
Does Antarctica have more ice?
Despite rapidly warming water, the amount of ice that floats on the Southern Ocean around Antarctica – known as sea ice – is slightly increasing.
Which Pole has more ice?
The Short Answer: Both the Arctic (North Pole) and the Antarctic (South Pole) are cold because they don’t get any direct sunlight. However, the South Pole is a lot colder than the North Pole.
What happens if Antarctica melts?
If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities. And land area would shrink significantly.
What is the coldest place on Earth?
AntarcticaScientists announced in 2013 they had found the lowest temperatures on Earth’s surface: Sensors on several Earth-observing satellites measured temperatures of minus 93 degrees Celsius (minus 135 degrees Fahrenheit) in several spots on the East Antarctic Plateau, a high snowy plateau in central Antarctica that …
Is the ice in Antarctica salty?
When sea ice forms, it rejects salt (ocean water is saline but sea ice is largely fresh) so dense salty water is formed which sinks and plays a key role in formation of Antarctic Bottom Water.
Why do airplanes not fly over Antarctica?
Why don’t planes fly over Antarctica? The White Continent does not have much in the way of infrastructure and herein lies why planes do not fly over it. Something called ETOPS (Extended Operations) governs how far from an emergency diversion airport certain aircraft are allowed to fly, according to its model.
Why is Arctic ice declining?
The Arctic sea ice decline has occurred in recent decades by sea ice in the Arctic Ocean melting faster than it refreezes in the winter. The IPCC, in its Fourth Assessment Report, stated that greenhouse gas forcing is predominantly responsible for the decline in Arctic sea ice extent.
Who was the first person born on Antarctica?
Emilio Marcos Palma (born 7 January 1978) is an Argentine man who was the first documented person born on the continent of Antarctica.
How deep is the ice in Antarctica?
4,776 metersAt its thickest point the ice sheet is 4,776 meters deep. It averages 2,160 meters thick, making Antarctica the highest continent. This ice is 90 percent of all the world’s ice and 70 percent of all the world’s fresh water.
Is the Arctic or Antarctica bigger?
The Arctic region includes the Arctic Ocean, parts of Greenland, Alaska, Canada, Norway and Russia, and covers about 5.5 million square miles. The Antarctic covers nearly the same area, 5.4 million square miles. 4. The Arctic Ocean accounts for more than five million square miles of the Arctic region.
Will there be another ice age?
Oddly enough, an Ice Age has gripped the Earth for most of the last 2.6 million years, and we’re currently experiencing an unusually warm break from this so-called Quaternary glaciation, which temporarily lifted around 12,000 years ago. … By itself, this will delay the next Ice Age by at least 50,000 years.

Is Arctic sea ice really declining?
Arctic sea ice reaches its minimum each September. September Arctic sea ice is now declining at a rate of 13.1 percent per decade, relative to the 1981 to 2010 average. This graph shows the average monthly Arctic sea ice extent each September since 1979, derived from satellite observations.
Is Arctic sea ice increasing or decreasing?
To them, Arctic sea ice is a reliable indicator of a changing global climate. They pay the most attention in September when Arctic sea ice shrinks to its smallest extent each year. Measured by satellites since 1979, this minimum extent has been decreasing by as much as 13.7 percent per decade.
Is Miami going to be underwater?
Miami could be underwater within 80 years, but rich people keep buying luxury waterfront homes — and local experts says there’s a simple explanation for it. Miami could be partially underwater and unlivable within 80 years, science indicates.
Why is the Arctic warming faster than the Antarctic?
Scientists agree that global warming causes both the ice in the North and the South Pole to melt. Air temperatures are climbing, and so are water temperatures. This makes the ice melt faster. … Because the Arctic and Antarctic are cold, remote, and full of ice, they are often thought of as nearly the same.
Do polar bears live in Antarctica?
Are there polar bears in Antarctica? No! Polar bears have never met penguins except in TV commercials (drinking soda) or in a zoo. Polar bears live in the Arctic (the North Pole) while the penguins live in Antarctica (the South Pole).
