Antarctica is huge. The Earth's southernmost continent is twice the size of Australia, and 98% of it is covered by ice. Antarctica is cold (the coldest recorded temperature is -89°C, from Vostok), but the peripheral islands and Antarctic Peninsula may have positive air temperatures in summer.

Antarctica hasn't always been covered with ice – the continent lay over the south pole without freezing over for almost 100 million years. Then, about 34 million years ago, a dramatic shift in climate happened at the boundary between the Eocene and Oligocene epochs.
What if Antarctica melted
The whole world will never be underwater. But our coastlines would be very different. 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.
What if Antarctica became a country
Yebbut What if Antarctica WAS a Country It would need other states to keep it supplied with essentials such as food and fuel and would need to find something, anything, to sell in return.

Is Antarctica untouched
Antarctica is the only continent on earth still largely untouched by man. The Antarctic Treaty of 1959 and the more recent Madrid Protocol of 1991 have helped preserve the South Pole as a place of peace, science, and environmental preservation and conservation.

Why Antarctica is showing so large
Mercator maps are not very good for showing the Antarctic continent from a world view because they distort the land in polar regions, making Antarctica look a lot bigger, relative to other continents, than it really is.
Why hasn’t anyone claimed Antarctica
Antarctica doesn't belong to anyone. There is no single country that owns Antarctica. Instead, Antarctica is governed by a group of nations in a unique international partnership. The Antarctic Treaty, first signed on December 1, 1959, designates Antarctica as a continent devoted to peace and science.
Why don’t we settle Antarctica
Antarctica is the only continent without a native population, or any true native Antarcticans. To this day, there is still no permanent human settlements or permanent residents, due to the unforgiving Antarctic environment, climate (the Antarctic is considered the coldest place in the world) and terrain.
What if Antarctica was green
If Antarctica were to be green again and have a climate where plants could grow like they do in the temperate or tropical regions, it would need the ice cover to melt to clear the land Then it would need soil to form, which would take hundreds to thousands of years and then it would need temperatures to increase very …
What if Antarctica was not frozen
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.

Why can’t we go over Antarctica

Specifically, because of the strong magnetic fields that surround the polar regions, navigating there, no matter how well-equipped the airplane is in terms of instrumentation, can be particularly challenging.
Why is Antarctica protected by military
The Antarctic Treaty was signed in 1959 by 12 countries and serves to protect Antarctica from destructive operations and war. It designates Antarctica as a scientific preserve and bans military activity, ensuring a collaborative effort through science and research among those who inhabit it.
What will happen to Antarctica in 2048
The Antarctic treaty expires in 2048. The Antarctic treaty is an agreement that sets aside the continent of Antarctica for peaceful scientific research. It does not permit any military activity on the continent and it also prevents mining and resource exploitation.
Are people not allowed to live in Antarctica
The people who travel to or live in Antarctica fall into two main groups, those who live and work on scientific research stations or bases, and tourists.
