Below the Antarctic ice lies a treasure trove of minerals, including copper, iron, gold, silver, platinum and cobalt. Warming temperatures due to climate change could unearth these minerals and, in turn, fuel future geopolitical conflict, potentially leading to a reversal of the current Antarctic drilling ban. If the ban is lifted, there may also be an increase in emissions. Those emissions would raise temperatures even more.
Iced out
Though under 0.6% of Antarctica is estimated to be free of ice cover today, scientists predict there will be up to a 550% increase during the next 30 years, according to a study published in the journal Nature Climate Change. And this climate-driven melting will lead to a “likely rise in the economic viability of Antarctic mineral resources over the coming centuries.” New accessible resources could pose problems in the future when it comes to determining whether these minerals can be mined and by whom.
A country’s interest in Antarctic mineral resource development may be “linked to whether it holds a territorial claim, the economic value of mineral resources within that claimed territory and the extent of land emergence,” said the study. The largest land emergence in Antarctica is “likely to occur over territories claimed by Argentina, Chile and the United Kingdom,” said Eos. But “all territorial claims on Antarctica were suspended by the 1959 Antarctic Treaty and are not recognized by other nations,” said The New York Times

Global copper demand is “currently at 28 million metric tons and is expected to jump to 42 million metric tons by 2040 as demand for electricity grows,” said the Times. Access to resources is going to become more important than ever. Changes to Antarctic ice cover could “put pressure on the region’s legal framework surrounding mineral resource activities,” said Eos. And interest may come from “states without territorial claims or non-state actors,” said the study.
Melting the ice
The Antarctic Treaty was signed in 1959 as a response to World War II and global interest in keeping Antarctica unmilitarized. The agreement stipulated that Antarctica should be “used for peaceful purposes only” and that “no acts or activities taking place while the present treaty is in force shall constitute a basis for asserting, supporting or denying a claim to territorial sovereignty,” said the treaty. It also bans any mining or drilling activities for commercial purposes.
These provisions may change in the future. Nations, beginning in 2048, will be able to request adjustments to the Antarctic Treaty. Along with Argentina, Chile and the U.K., Australia, New Zealand, France and Norway also made formal land claims to Antarctica before the treaty. “Major powers like the United States and Russia, though not formal claimants, retain strategic interests and could play a key role if rules around resource extraction change,” said Money Control.
Drilling in Antarctica can have significant negative environmental impacts, including the release of trapped greenhouse gases. Increased greenhouse gases would lead to worsening climate change, which would cause additional ice melt. In the future, “environmental impacts of mineral resource extraction activities will be weighed against societal pressure for sustainable resource development,” said the study.
Nonetheless, the ice melt is ”unlikely to trigger a major change to Antarctic governance on its own,” Tim Stephens, a professor of international law at The University of Sydney Law School, said to Eos. “The continent will still remain a very challenging environment for mineral resource extraction.”
