In 2024, Perito Moreno Glacier in southern Argentina attracted nearly 700,000 visitors who witnessed significant ice collapse, signaling its accelerated retreat. Since 2018, the glacier has lost nearly 2,000 meters in margin as climate change-induced rising temperatures and resultant melting have disrupted its equilibrium. Experts Pedro Skvarca and Lucas Ruiz emphasize that Perito Moreno has broken its long-held balance, wherein it now loses more ice than it can replenish annually, paralleling global glacier trends due to climate change.
Rising temperatures caused by climate change have been decisive in the reduction of the ice mass. The climate is warmer, there is more melting and more water at the base.
The noticeable and accelerated retreat of the glacier indicates the loss of mass has become irreversible, marking a significant departure from the equilibrium it maintained for over a century.
Perito Moreno has broken the exceptional balance that distinguished it from other glaciers, meaning annual ice accumulation is now less than annual ice loss.
The amount of ice accumulated at its sources is now significantly reduced, leading to an increased retreat that reflects a broader trend observed in glaciers.
