In 18% of the regions of the planet Earth, the circulation of fresh water has been significantly disrupted as a result of human activity
A new study by an international team of scientists has concluded that aquifer depletion is affecting countries around the world and can threaten both the stability of local ecosystems and water security, with groundwater pumping causing the entire planet to tilt. Also, an international team of hydrologists and climatologists comprehensively studied the fresh water cycle on Earth and came to the conclusion that in 18% of the planet’s regions, the circulation of fresh water between rivers, ponds, lakes, other bodies of water and other environments has been significantly disrupted as a result of human activity.
Alaska’s Columbia Glacier is one of the fastest-changing glaciers in the world
ESA’s (European Space Agency) Copernicus Sentinel-2 mission explored Alaska’s Columbia Glacier, one of the fastest-changing glaciers in the world. The Columbia Glacier is a tidal glacier flowing down the snow-covered slopes of the Chugach Mountains. The mountains contain the largest concentration of glacial ice in Alaska. Since the early 1980s, the Columbia Glacier has retreated more than 20 km and lost about half of its total volume. This glacier accounts for nearly half of the ice lost in the Chugach Mountains.
