Round 2: Vanishing Water Towers

Matchup 3: Indus River vs East River

Indus River

Many anthropogenic disturbances threaten water quality and quantity across the Indus River, including increases in dams, mining, agriculture, and glacial melt due to climate change.

East River SFA

Climate change is the major driver of snowmelt and altered hydrology in the East River SFA where scientists study the affects of warming and drought on the hydro-biogeochemical functioning of mountainous watersheds.

Matchup 4: Niwot Ridge vs Cayambe

Niwot Ridge LTER

Climate data has been continuously collected at this site for well over 40 years and has been used to validate changes in smowmelt-driven ecosystems, such as altered volumes of snow and nitrogen deposition.

Cayambe River

Tropical glaciers in the Andes are particularly vulnerable to climate change due to their year-round melt, and have been melting at alarming rates as the globe warms. Melt from this glacier supplies a steady water source to indigenous Kichwa communities living downstream.
