Antarctica has no followers yet. Be the first one to follow.
Scientists reported that the entire Antarctic continent has been slowly warming since at least 1957.
In western Antarctica a 160-square mile chunk of ice on the edge of the Wilkins ice shelf began collapsing. It had been there for 1,500 years.
A team of NASA and university scientists has found clear evidence that extensive areas of snow melted in west Antarctica in January caused by warm temperatures. Combined, the affected regions make an area as big as California.
Antarctic researchers reported that the ice cap’s glaciers are now melting twice as fast as in the 1990s and raising sea level.
A storm split apart the world's largest iceberg off the coast of Antarctica. It is believed to have caused the deaths of millions of penguins after it blocked access to the sea from the Ross Ice Shelf.
Scientists reported that the Larsen B ice shelf in Antarctica, covering some 1,250 square miles, had collapsed into small icebergs.
Thousands of Antarctic penguins were reported dead or dying because giant icebergs cut the birds off from their food supply.
Scientists reported that the ozone layer over Antarctica had grown to 11 million square miles.
An iceberg 183 miles long and 22 miles wide, twice the size of Delaware, broke adrift in the Ross Sea.
The ozone layer over Antarctica was reported to have grown to over 8 million square miles!
The Antarctic Larson B and Wilkins ice shelves were reported to have lost 1,100 sq. miles due to warm temperatures over the last year.
The ozone hole over Antarctica reached 10.5 million sq. miles. It opened to 2 1/2 times the size of Europe.
A report on the West Antarctic Ice Sheet said that changes have been detected by satellite that might indicate a future collapse.
It was reported that the 8,000 Sq. mile Larsen B ice sheet in Antarctica was breaking up due to rising temperatures.
The size of the ozone hole over Antarctica surpassed 8.5 million square miles.
The ozone hole over the Antarctic was measured to be three times the size of the United States. Prof. James Terri, "If the release of CFC'S (chlorofluorocarbons) is stopped instantly, it would take nearly 100 years for the ozone to recover.”
Great pieces of ice broke from the coast of Antarctica. The Larsen Ice shelf calved (the process of pieces of ice breaking off) an 8,000 km iceberg, icebergs from the Filchner Ice Shelf combined to 11,500 km.
The thinning of the ozone layer over Antarctica was first reported.
The Antarctic Treaty was signed by many nations, who promised to use Antarctica only for scientific studies.
Captain John Davis, part of an American group of explorers, landed on the continent at Hughes Bay on the Antarctic Peninsula. Much of the early exploration was directed at finding good hunting grounds for seals.
Fabian Gottlieb von Bellingshausen became the first person to spot land on the continent.
Captain James Cook and his crew became the first men to cross the Antarctic circle.
