Los Incendios del Amazonas Contribuyen al Derretimiento de los Glaciares Andinos

by Michael Allen 25 February 202023 March 2023

Investigaciones recientes revelan que las emisiones de carbono negro producidas por los incendios en el Amazonas causan que los glaciares en los Andes absorban más radiación solar y se derritan más.
