Rising atmospheric carbon dioxide is causing global warming. This means glaciers in Antarctica are melting. Those same glaciers were originally made when carbon dioxide dropped 34 million years ago. (NASA/Jim Ross)

Drop in Greenhouse Gas Caused Global Cooling 34 Million Years Ago, Study Finds

Smooth pearls in the shape of orbs and ovals are usually created by bivalves, like mussels, in pearl farms. As with all gems, the less blemishes they have, the more valuable they are. (Chip Clark, Smithsonian)

The True Story Behind How Pearls Are Made

While this year’s Arctic sea ice extended further than last year’s, there still wasn’t as much of it as there was only two decades ago. Thinner and younger sea ice in winter and less ice in the summer are two of the many elements of the Arctic’s new reality. (Credit: Patrick Kelley, U.S. Coast Guard. Public domain.)

Climate Change Redefines What 'Normal' Means in the Arctic

Climate change is causing oceans to warm, which in turn affects fish and fishers. Now, scientists are turning towards management strategies to protect species and the industry. (Claudio Contreras-Koob/International League of Conservation Photographers)

Why Fishes are the Catch of the Day for Climate Research

Coral reef health is an important indicator of the ocean’s well-being. Scientists can study corals to learn more about how climate change is affecting the oceans. (Wise Hok Wai Lum, CC-BY-SA-4.0)

DNA Makes Waves in the Fight to Save Coral Reefs

Through research on living and preserved fungus-farming ants, entomologists are learning more about the insects’ deep connection to their environment and how that relationship might evolve in response to a changing climate. (Smithsonian)

How Fungus-Farming Ants Fertilize Climate Research

Through research on living and preserved plants, botanists are learning more about how flora has responded to climate change over the past centuries. (USDA photo by Preston Keres)

Why Plants are Seeding Climate Studies

Fossil plants reveal information about the temperature and precipitation of past climates. Scientists use what they learn from fossil plants to inform their research on modern climate change (USNM PAL 606436, Smithsonian)

What Fossil Plants Reveal About Climate Change

Many organisms like coral — and even people — create their own minerals to perform basic life functions. Geologists can study these biominerals to learn more about Earth. (Donald E. Hurlbert, Smithsonian)

How Biominerals are Stepping Stones for Climate Change Research

This mummified steppe bison was donated to the Smithsonian’s National Museum of Natural History in the 1970s. Right now, museum audiences can see it online during a virtual tour. (Michelle Pinsdorf, Smithsonian)
