ANTARCTICA: SCIENTISTS DISCOVER HUGE CHANGE AFTER DRILLING INTO ICE Antarctica is the Earth’s southernmost continent, located on the South Pole, where temperatures can be as low as -90C. 

Anywhere between 1,000 and 5,000 scientists reside there at various research facilities, carrying out their own experiments. However, one investigation left a team of researchers astonished.

RELATED ARTICLES Amazon Prime’s “Antarctica – An Adventure Of A Different Nature” revealed the moment scientists dug almost 500ft into an ice sheet to learn about the icy continent’s

history. The 1991 documentary explained: “A core drill digs deep into the ice sheet.  “Ice layers can read like the rings of trees and the climate record goes back 100,000 years.  “Entrapped

atmosphere change, so does the climate.” However, when the scientists analysed the ice layer, they were left stunned.  The series explained: “A day, a week, a month, a year, a decade – the

core came from 466ft down and its ice fell as snow about 4,000 years ago. “From the crystal of the ice, the news from Antarctica is bad.  They drilled into the ice sheet to take a saple

effects.  “20 years ago, scientists predicted man-made chemicals would thin the planet’s protective layer of ozone.  “That has now become dramatic.” In May 1985, Joseph Farman, Brian

Gardiner and Jonathan Shanklin observed a decline in the polar ozone was far larger than believed. The discovery of the ozone hole was initially rejected as unreasonable but later studies

showed that the concerns were valid. RELATED ARTICLES Since 1991, the United Nations Environment Programme has sponsored a series of technical reports on the Scientific Assessment of Ozone

Depletion to reverse the effects.  In 2007, a report was released that showed the hole in the ozone layer was recovering and was the smallest it had been for around a decade.  The 2010 paper

read: "Over the past decade, global ozone and ozone in the Arctic and Antarctic regions is no longer decreasing but is not yet increasing.  “The ozone layer outside the Polar regions

is projected to recover to its pre-1980 levels before the middle of this century.  They took a large sample of ice (Image: AMAZON PRIME) “In contrast, the springtime ozone hole over the

Antarctic is expected to recover much later."  In 2012, NASA confirmed the hole had decreased once again. They revealed: "Warmer air temperatures high above the Antarctic led to

the second smallest season ozone hole in 20 years averaging 17.9 million square kilometres.  “The hole reached its maximum size for the season on September 22, stretching to 21.2 million

square kilometres (13.8 million square miles)." Antarctica is an untouched nation, used for scientific research` (Image: GETTY) The frozen desert is home to some of science's most

amazing discoveries. In 2010, David Walton, Professor at the British Antarctica Survey, revealed how a team uncovered an extinct species known as the Palaeeudyptes klekowskii or colossus

penguin. He told BBC Radio 4 listeners: “We know there were dinosaurs there and we know there were giant penguins too – 6ft tall in fact. “We reconstructed a penguin from a single metatarsal

that was found – it is amazing what you can do with one bone. “So we know it was a much more interesting continent previously.” ANTARCTICA: SCIENTIST REVEALS GREATEST DISCOVERY OF SOUTH

POLE The unearthed bones dated back 37 million years and new studies show the species could have measured almost twice the height of today's emperor penguins. It is believed the penguin

could have weighed up to 19 stone, making it possible to dive deeper and stay underwater for longer.  However, Antarctica also has a dark past too. It was previously revealed the US

secretly launched three nuclear rockets from below the ice.
