Earth has experienced climate change in the past without help from humanity. We know about past climates because of evidence left in tree rings, layers of ice in glaciers, ocean sediments, coral reefs ...

Goddard’s LiDAR, Hyperspectral, & Thermal Imager (G-LiHT) is an airborne instrument designed to map the composition of forested landscapes. The G-LiHT instrument has a number of sensors that each ...

Though blizzards and cold snaps may have made you forget the news from last week, 2015 was the warmest year in NASA’s global temperature record, which dates back to 1880. During a January 2016 press ...

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 ...

If you follow Earth and climate science closely, you may have noticed that the media is abuzz every December and January with stories about how the past year ranked in terms of global temperatures.

The time it takes carbon to move through the fast carbon cycle is measured in a lifespan. The fast carbon cycle is largely the movement of carbon through life forms on Earth, or the biosphere. Between ...

Air temperatures on Earth have been rising since the Industrial Revolution. While natural variability plays some part, the preponderance of evidence indicates that human activities—particularly ...

The most valuable fossils found in sediment cores are from tiny animals with a calcium carbonate shell, called foraminifera. One species of foraminifera lives in the icy waters of the Arctic above ...

Have you ever wondered what it would be like to live in a different part of the world? What would the weather be like? What kinds of animals would you see? Which plants live there? By investigating ...

Among the first things the data revealed was a definite seasonal difference in cloudiness over the polar regions. Cloud fraction (the fraction of the area in a map’s grid box covered by cloud) over ...

All of this extra carbon needs to go somewhere. So far, land plants and the ocean have taken up about 55 percent of the extra carbon people have put into the atmosphere while about 45 percent has ...

Review the biomes. Now examine the set of temperature and precipitation graphs given below for each city. Be careful reading the scales on the graphs. Using the pull-down menus, select the correct ...
