A new report released this week by high-resolution satellite imagery provider DigitalGlobe in partnership with Extreme Ice Survey (EIS) reveals environmental changes as told by the world’s climate change barometers – glaciers. Using a combination of on-the-ground photography with satellite imagery to monitor the state of the world’s glaciers, the organizations issued the “Worldwide Glacier Monitoring Report,” a first in a series of reports that depict satellite images from the last three years to show how three glaciers – Khumbu Glacier at Mt. Everest, the Ilulissat Glacier in Greenland and the Breidamerkurjökull Glacier in Iceland – have changed over time.
Glaciers are a clear indicator of the state of the environment and a thermometer of local and regional climate conditions. Since 1995, Ilulissat Glacier, the largest producer of icebergs in Greenland, doubled its flow speed and volume of ice discharged due to warming air and ocean temperatures. The combined effect of ice loss in mountains and ice caps in Greenland and Antarctica will produce at least 3 feet of sea level rise by 2100, dislocating at least 150 million people. As the planet becomes warmer, sea levels will continue to rise.
