The majority of the almost 50 large glaciers in Los Glacieres National Park have been retreating during the past fifty years due to warming temperatures, according to the European Space Agency (ESA). The United States Geological Survey (USGS) reports that over 68 percent of the world's freshwater supplies are locked in ice caps and glaciers.

WASHINGTON, DC - JUNE 27: U.S. Attorney General Pam Bondi speaks alongside President Donald Trump on recent Supreme Court rulings in the briefing room at the White House on June 27, 2025 in Washington, DC. The Supreme Court ruled 6-3 that individual judges cannot grant nationwide injunctions to block executive orders, including the injunction on President Trump’s effort to eliminate birthright citizenship in the U.S. The justices did not rule on Trump’s order to end birthright citizenship but stopped his order from taking effect for 30 days.
