A stormy sea lashes the village of Shismaref, Alaska, where the coastline has eroded 30–90 m (100–300 ft) in the past 30 years.
Since summer 2013, starfish along both coasts of the United States have been dying in large numbers—and not gracefully. As their tissues collapse, the starfish (also called sea stars) start to look...
A humboldt squid ( Dosidicus gigas )—also known as the jumbo squid—releases a cloud of ink at night in Mexico's Sea of Cortez. These large, carnivorous squids can reach more than 5 feet in length and...
Worldwide, installations of solar energy doubled from 2007 to 2008. China is leading the way in solar cell production. More about climate change can be found in our climate change featured story .
The nation of the Maldives is made up of 1,190 coral islands grouped into 26 atolls in the Indian Ocean. Most of their land is barely above sea level and could literally disappear if sea level rises...
Lenticulina secans -- this foram lives on the seafloor. This specimen was collected from ocean sediments in southeast Tanzania. It comes from a time over 92 million years ago when both the polar...
Fossil fuels that power our cars, homes, and businesses add carbon dioxide (CO2) to the atmosphere. The ocean absorbs large portions of this CO2 and acts as a buffer against climate change . But, Dr...
