            "title": "Ice Loss on Puncak Jaya",
            "description": "Tropical glaciers have retreated significantly in the past century, and many have lost more than half of their ice in the last few decades. Indonesia’s glaciers are no exception. In 1989, five ice masses sat on the slopes of Puncak Jaya, a 4,884-meter peak within the Sudirman Range. By 2009, two of the glaciers—Meren and Southwall—were gone. The other three—Carstenz, East Northwall Firn, and West North Wall Firn—had retreated dramatically.This pair of images, captured by the Thematic Mapper (TM) on Landsat 4 and Landsat 5, offer a view of the ice loss between 1989 and 2009. The images are a combination of shortwave infrared, near infrared, and green light. Ice appears light blue. Clouds are primarily white, though some are tinged with blue. Exposed rock is salmon-colored; forests are green. (The gray area near the center of the 2009 image is the Grasberg mine. Established in 1990 by Freeport McMoran, the open-pit mine has the world’s largest known gold reserve and second largest copper reserve.) || ",

            "title": "Columbia Glacier, Alaska",
            "description": "The Columbia Glacier in Alaska is one of the most rapidly changing glaciers in the world. These false-color images show how the glacier and the surrounding landscape has changed since 1986. Snow and ice appears bright cyan, vegetation is green, clouds are white or light orange, and the open ocean is dark blue. Exposed bedrock is brown, while rocky debris on the glacier’s surface is gray. By 2011, the terminus had retreated more than 20 kilometers (12 miles) to the north. Since the 1980s, the glacier has lost about half of its total thickness and volume. The retreat of the Columbia contributes to global sea-level rise, mostly through iceberg calving. This one glacier accounts for nearly half of the ice loss in the Chugach Mountains. However, the ice losses are not exclusively tied to increasing air and water temperatures. Climate change may have given the Columbia an initial nudge, but it has more to do with mechanical processes. In fact, when the Columbia reaches the shoreline, its retreat will likely slow down. The more stable surface will cause the rate of calving to decline, making it possible for the glacier to start rebuilding a moraine and advancing once again. || ",

            "description": "Over the past three decades, Saudi Arabia has been drilling for a resource more precious than oil. Engineers and farmers have tapped ancient reserves of water, dating back to the last Ice Age, to grow crops in the desert. This series of false-color satellite images show the evolution of agricultural operations in the Wadi As-Sirhan Basin. New vegetation appears bright green while dry vegetation or fallow fields appear rust colored. Dry, barren surfaces (mostly desert) are pink and yellow. Saudi Arabians have reached this underground water source by drilling wells through sedimentary rock, as much as a kilometer beneath the desert sands. Rainfall averages just 100 to 200 millimeters per year and usually does not recharge the underground aquifers, making the groundwater a non-renewable source. Although no one knows how much water lies beneath the desert—estimates range from 252 to 870 cubic kilometers—hydrologists believe it will only be economical to pump it for about 50 years. || ",

            "description": "The region around the Pearl River Estuary in southern China experienced rapid urban growth in the 1980s and 1990s. This growth was spurred by the establishment of special government economic zones, particularly in Shenzhen, just to the east of the estuary. Urban areas increased by more than 300% between 1988 and 1996. This growth can be directly assessed by remote sensing measurements from space, particularly by comparing images from the Landsat sensors for the last thirty years. This animation shows nine such images in sequence, from the years 1973, 1975, 1977, 1979, 1988, 1992, 1995, 2000, and 2001. || ",

            "description": "Throughout much of the 1980s, deforestation in Brazil eliminated more than 15,000 square kilometers (9000 square miles) per year. That pace has only increased through the 90s and into the 21st century.Brazil is also home to more than a quarter of Earth's tropical forests. Considering that the band of lush green that circles the globe through many equatorial nations is fundamental to the overall health of the whole planet's environment, careful monitoring of forest health in the tropics is essential. Tropical forests act as major carbon 'sinks', places where ambient carbon dioxide in the atmosphere can be absorbed by growing things and sequestered for years. Definitive evidence shows that excess carbon dioxide can contribute to the greenhouse effect and speed global warming. Similarly, tropical forests also act as a primaryproducer of oxygen. In the respiration process that absorbs gaseous carbon dioxide, trees and other plants give off oxygen.It is for these and a host of other reasons why scientists and policy makers need to monitor and forestall wholesale deforestation.This sequence shows how profligate clear cutting can influence that trust. Data gathered over time by several in the Landsat series of spacecraft shows enormous tracts of forest disappearing in Rondonia, Brazil. This territory underwent an enormous rise in population towards the end of the twentieth century, buoyed by cheap land offered by the national government for agricultural use. As you see the visualization progress, it is useful to note how the human phenomenon of deforestation generally works, especially in the dense tropical forests of Brazil. Systematic cutting of a road opens new territory to potential deforestation by penetrating into new areas. Clearing of vegetation along the sides of those roads tends to fan out to create a pattern akin to a fish skeleton. As new paths appear in the woods, new areas become vulnerable. The spaces between the 'skeletal bones' fall to defoliation, and another inch of the Earth's biological rudder is no longer reliably steering the planet into the future. || ",
