Cảnh báo tình trạng tan băng

09:20 11/02/2025

Không chỉ góp phần điều hòa khí hậu, sông băng còn cung cấp các nguồn nước thiết yếu cho con người. Tuy nhiên, biến đổi khí hậu và gia tăng khí thải nhà kính đang khiến các sông băng tan chảy nhanh hơn, gây nên nhiều hệ lụy. Trong bối cảnh đó, Liên hợp quốc tuyên bố năm 2025 là Năm quốc tế bảo tồn sông băng, kêu gọi chung tay đối phó sự biến mất nhanh chóng của băng và bảo vệ các nguồn nước quan trọng.
