Only 309,000 square miles of forest were gained during that period. Between 20, some 880,000 square miles of forest were lost, largely in tropical and subtropical areas. Users of the map have the ability to zoom in on small regions of the globe and see how forest cover has changed over time.Īnd what the scientists found in terms of deforestation, as detailed in a paper published Thursday in the journal Science, alarmed them. It has allowed them to quantify forest gain and loss each year from 2000 to 2012, whether from logging, fires or storms. Using archived imagery captured by a NASA satellite called Landsat, Hansen and his team used Google Earth Engine computing to map a detailed view of global forests at 30-meter resolution that they say is a vast improvement over previous knowledge of forest cover. ![]() “It’s a long-held goal of our discipline to do accurate mapping of Earth’s and the land’s surface and how it changed over time.” “This project is a really big deal in terms of special detail,” he told Al Jazeera in a telephone interview. Geographers and climate scientists have been using satellites for a few decades in order to observe the Earth’s surface, but the resulting images were “big, blurry messes,” says Matthew Hansen, a professor of geographical sciences at the University of Maryland who led the research team. government to create the first high-resolution map of the world’s forests, using detailed satellite imagery to document growth and loss of some of the planet’s key ecosystems over time. Argonne Forest park, an amusement park in Dayton, Ohio built by a former U.S.Scientists have teamed up with Google and the U.S.Argonne Forest, an affluent neighborhood in Atlanta, Georgia.The monument is located 32 km (20 mi) northwest of Verdun, not far from the Meuse–Argonne American Cemetery and Memorial.

Roberts and William Henry Johnson (a.k.a. During the Meuse–Argonne offensive (1918), several United States Army soldiers earned the Medal of Honor there, including Colonel Nelson Miles Holderman, Major Charles White Whittlesey, Sergeant Alvin C. Bitter fighting between German and Allied units took place here in fall and winter 1914, summer 1915, and fall 1918. In 1792, Charles François Dumouriez outmaneuvered the invading forces of the Duke of Brunswick in the forest before the Battle of Valmy.ĭuring World War I, the forest again became the site of intense military action. Common animal life consists of wild boar, red deer, roe deer, hares, rabbits, foxes, and wildcat. The forest is largely oak, chestnut, and pine trees, and ferns cover much of the forest floor. The forest is bordered by the Meuse River on the west and rolling farmland and creeks to the east. ![]() Following the First World War, the landscape of the forest was forever changed as trench warfare led to parts of the forest being riddled with deep human-made trenches along with craters from explosives. The forest measures roughly 65 km (40 mi) long and 15 km (9 mi) wide filled with many small hills and deep valleys formed by water run-off from the Aire and Aisne rivers rarely exceeding more than 200 m (650 ft) in elevation. The Forest of Argonne ( French pronunciation: ) is a long strip of mountainous and wild woodland in northeastern France, approximately 200 km (120 mi) east of Paris. soldiers in the Argonne Forest resting in a trench, 1918 Henry Johnson, known after his heroic battle as the Black Death, and Sgt. ![]() Location of Forest of Argonne in northeastern France Forest of Argonne in 1915 Forest of Argonne in a valley near Chatel-Chéhéry, France, where Sgt.
