The coldest continent on Earth is Antarctica. Positioned at the southernmost part of the planet, it experiences extreme temperatures, with recorded lows reaching below -128 degrees Fahrenheit (-89 degrees Celsius). This icy continent is covered by a thick layer of ice, comprising about 70% of the world's fresh water. Despite its harsh climate, Antarctica is home to a range of unique wildlife, including penguins, seals, and various seabirds. The continent plays a critical role in global climate regulation and is a key area of interest for scientific research about climate change and Earth's ecosystems.
