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 ...

Thirteen years ago, a satellite acquired this beautiful image (above) of light and sand playing off a portion of the ocean floor in the Bahamas. The caption that accompanied the image didn’t include ...

The Sun provides the energy that drives Earth’s climate, but not all of the energy that reaches the top of the atmosphere finds its way to the surface. That’s because aerosols—and clouds seeded by ...

A new fissure opened on the Reykjanes peninsula in southwestern Iceland near Grindavík in December 2023 and continued erupting throughout 2024. Whether sparked by lightning, intentional land-clearing, ...

We are still at South Pole Station. As we were finishing up the preparation of the sleds used on the 88S Traverse, we realized that we were missing a couple of fittings that pair our propane tank to 2 ...

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 ...

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 ...

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 ...
