Description: The Dark Snow project is a crowd-funded citizen science project to quantify changes in the reflectivity of the ice in Greenland. They are attempting to combine climate change with social media to impact research in the area of albedo-temperature feedback. They have funded two campaigns to study the ice using drones and satellite imagery. The work of this group could allow students to study feedback between Earth systems, discuss climate change, or as a jumpstart for a project of their own.
Description: Glacier National Park used to have 150 glaciers and it now has 25. Photographic evidence in this video shows how drastically the glaciers are being shaped by a warming planet. This phenomenon can be used to show two forms of freshwater (ice and water) in elementary science and as evidence for global warming in secondary.
