Argentina's Congress approved legislation Thursday that weakens protections for glaciers and permafrost in the Andes mountains, opening previously restricted areas to mining operations. The Chamber of Deputies passed President Javier Milei's bill with 137 votes in favor, 111 against, and three abstentions after more than eleven hours of debate.
The reform fundamentally alters Argentina's 2010 glacier law by limiting full protection to glaciers with a "proven hydrological function." Periglacial environments — permafrost formations and smaller ice bodies surrounding glaciers — lose automatic protection and will be evaluated case-by-case through technical studies.
Authority over glacier classifications transfers from federal to provincial governments. Local jurisdictions now determine which formations remain in the National Glacier Inventory and which areas open to extractive activities. The Argentine Institute of Snow Research, Glaciology and Environmental Sciences retains technical oversight but operates under provincial decisions.
Mining sector estimates suggest the regulatory changes could unlock over $30 billion in investments over the next decade, with approximately 70% targeting new copper, gold, and silver projects. Argentina holds estimated copper reserves of 17.1 million metric tons, concentrated in northwestern provinces where glacial reserves have shrunk 17% in the past decade due to climate change.
Thousands of protesters gathered outside parliament Wednesday, holding banners declaring "Water is more precious than gold!" and "A glacier destroyed cannot be restored!" Seven Greenpeace activists were arrested after scaling a statue and unfurling a banner urging lawmakers not to "betray the Argentine people."
The Guardian frames this as environmental destruction driven by Milei's libertarian ideology, emphasizing climate change denial and protest suppression. Their coverage highlights the contradiction between economic development and environmental protection, reflecting Britain's own tensions over balancing climate commitments with economic pressures.
Mercopress provides technical detail on the legislative mechanics and provincial authority transfers, reflecting Uruguay's regional perspective on Argentine policy changes. Their neutral framing emphasizes institutional processes over environmental concerns, typical of regional outlets focused on economic implications for neighboring countries.
Mongabay emphasizes environmental advocacy and legal challenges, framing the story through conservation priorities typical of US environmental journalism. Their focus on court battles and activist responses reflects American approaches to environmental protection through litigation and civil society mobilization.
The science is clear … there is absolutely no possibility of creating what they call a 'sustainable mine' in a periglacial environment.

Environmental groups are preparing legal challenges, with organizations including Greenpeace and the Environment and Natural Resources Foundation organizing a class-action lawsuit. They argue the reform threatens water access and fragile ecosystems surrounding Argentina's nearly 17,000 glaciers and rock glaciers.
If they refuse to listen in Congress, they will be forced to listen in the courts.

The legislation represents another victory for Milei, who previously pushed through looser labor laws despite street protests. The libertarian president, who disputes human-caused climate change, frames the bill as necessary to attract large-scale mining investments to boost Argentina's struggling economy.
Opposition lawmakers have declared the legislation unconstitutional, arguing it rolls back essential environmental protections. The bill includes a precautionary principle protecting currently inventoried ice bodies until authorities verify the absence of hydrological functions, but establishes that delays in updating the inventory will not affect provincial mining authorizations.
