In 1967 Hansen went to work for NASA’s Goddard Institute for Space Studies, in New York City, where he continued his research on planetary problems. Around 1970, some scientists suspected Earth was ...

Examine the set of graphs below for a given city. Read carefully the temperature and precipitation scales on the graphs. Review the biome information. Two biome choices are given for each set of ...

Not all of NASA’s rovers are headed to Mars. A new Earth science rover nicknamed GROVER started roaming Greenland’s ice sheet this week. The autonomous, solar-operated robot carries a ...

A rain gauge will collect how much rain falls, but how exactly do scientists measure the size, shape, and fall speed of raindrops near the ground? Patrick Gatlin of NASA’s Marshall Space Flight Center ...

Just as the incoming and outgoing energy at the Earth’s surface must balance, the flow of energy into the atmosphere must be balanced by an equal flow of energy out of the atmosphere and back to space ...

Phytoplankton thrive along coastlines and continental shelves, along the equator in the Pacific and Atlantic Oceans, and in high-latitude areas. Winds play a strong role in the distribution of ...

Phytoplankton are the foundation of the aquatic food web, the primary producers, feeding everything from microscopic, animal-like zooplankton to multi-ton whales. Small fish and invertebrates also ...

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 ...

Among the mysteries of the South American Monsoon, explains Fu, is how the first thunderstorms of the wet season get started. A monsoon is an atmospheric see-saw in which the large-scale circulation ...

The water, or hydrologic, cycle describes the pilgrimage of water as water molecules make their way from the Earth’s surface to the atmosphere and back again, in some cases to below the surface. This ...
