Antarctica is a unique continent scientifically, environmentally and geopolitically. Here is why it matters far beyond the postcard.
The planet's climate archive
It is one of the least human-altered places on Earth. Antarctic ice cores preserve atmospheric records hundreds of thousands of years old and underpin nearly everything we know about past climate.
Irreplaceable biodiversity
Despite extreme conditions it hosts species found nowhere else: from the krill sustaining the whole Southern Ocean food chain to the emperor penguin breeding in the depth of polar winter.
Global regulation
- It holds around 90% of the world's ice and 70% of its fresh water.
- The Antarctic circumpolar current distributes heat and nutrients across all oceans.
- The white ice reflects solar radiation and moderates global temperature.
Sovereignty and treaty
The 1959 Antarctic Treaty froze every territorial claim: the continent is dedicated to peace and science, bans military and mining activity, and its 50-plus signatory countries regulate tourism through strict environmental protocols.
Visiting under IAATO rules — limited landings, minimum distances, biosecurity — is the only responsible way to see the seventh continent.
