Blast From the Past: A Modern Lake in an Ancient Crater Famously visible from space, ring-shaped Manicouagan Lake was filled at the dawn of the Space Age when Canada dammed a river to flood a Triassic ...
“There’s a debate about how cities affect rainfall,” Shepherd answers. “There are several hypotheses about what is going on, but they primarily involve the urban land use and urban aerosols.” The ...
A string of dry years shriveled vegetation in Africa's Sahel, causing some to fear that the Sahara Desert was shifting south. Satellite data spanning more than twenty years now shows that the Sahel is ...
Glaciers: Ice on the Move November 2018 EO Kids is looking at glaciers from space. Imagery and data are showing that many glaciers are shrinking. In the issue, you will discover more about these cool ...
If Earth’s oceans are soaking up the excess heat energy caused by greenhouse gases, then exactly what is the problem? The problem—and perhaps part of the solution as well—is thermal inertia. Inertia ...
Updated Oct 19, 2019 World of Change: Antarctic Ozone Hole In the early 1980s, scientists began to realize that CFCs were creating a thin spot—a hole—in the ozone layer over Antarctica every spring.
Long-term changes in phytoplankton Productivity Because phytoplankton are so crucial to ocean biology and climate, any change in their productivity could have a significant influence on biodiversity, ...
Aerosols also have complex effects on clouds and precipitation. Broadly speaking, aerosols are thought to suppress precipitation because the particles decrease the size of water droplets in clouds.
As the Earth heats up more water will make its way into the atmosphere, trapping even heat near the surface. To predict how much temperatures could rise in the future, scientists are working to ...
Bridging the Data Gap “IceBridge exists because we need to understand how much ice the Greenland and Antarctic ice sheets will contribute to sea level rise over the next couple of decades,” says ...
In principle, it should be possible to add up each of the individual components of sea level rise—melting continental ice sheets in Antarctica and Greenland, retreating glaciers, the thermal expansion ...
Although there was little in the way of published research on estimating U.S. lawn area, the research group Milesi was studying and working with at the University of Montana had a lot of experience ...
