Antarctica
Antarctica is Earth's southernmost continent, almost entirely covered by ice, and governed under an international treaty that reserves it for peaceful scientific research.
Antarctica holds about 70% of the world's fresh water, locked in its massive ice sheets, and is the coldest, windiest, and driest continent on Earth, with no permanent human residents beyond rotating research station staff.
The Antarctic Treaty, signed in 1959 by 12 countries and now with over 50 signatories, designates the continent as a scientific preserve, banning military activity and mineral resource extraction.
Scientists conduct extensive research in Antarctica on climate change, as ice core samples provide detailed records of Earth's atmospheric history stretching back hundreds of thousands of years.
