4.1 Environmental Change Around You
In this section you will find materials that support the implementation of 4.1: Environmental Change Around You. Use the navigation below to find the materials.
Visions of Earth, by AGI
A four-DVD set on interactions in Earth systems.
Repeat Photography Project, by USGS
Scientists with the Global Change Research Project are unveiling a new website featuring a collection of repeat photographs of glaciers in and around Glacier National Park, Montana. The striking images created by pairing historical photographs with contemporary photographs reveal significant glacial recession.
Earthshots: Satellite Images of Environmental Change, by USGS
This USGS site has images from all over the world. It compares the changes that have occurred over time.
Glaciation, by NOAA
Find information and data on Glaciation as well as an online slide show.
Climate change and human health, by The World Health Organization
This website describes the effects of global environmental change.
Visions of Earth, by AGI
82 High-definition animations showing a variety of Earth and space system processes.
Jakobshavn Glacier Calving Front Recession from 1850 to 2006, by NASA
Learn more about the Jakobshavn Glacier.
Sea Level Rise "What Ifs" in the Southeastern United States, by NASA
This visualization shows the Southeastern United States with population data over the land. Darker areas over land indicate higher population densities. Sea level scenarios are shown starting with 0 meters of sea level rise (current sea level) and proceeding through 9 meters of rise. Blue areas moving inland indicate where the coastline would be at various levels. We will likely see some sea level rise in our lifetimes, but the middle-to-higher levels in this visualization are unlikely in the next 100 years. This visualization is based on Shuttle Radar Topography Mission (SRTM) data. This data primarily measured canopy heights. So, this visualization is showing where water might reach the tops of the trees in various areas.
Earth Observatory, by NASA
This web site contains images generated by remote sensing instruments carried by the satellites orbiting Earth. Students can study environmental changes over time by creating their own animations on this site. The site contains data on chlorophyll concentrations, ocean temperatures, snow cover, aerosols, wildfires, carbon monoxide concentrations, cloud cover and much more.
