Burning fossil fuels, such as coal, oil and natural gas, spews almost 7 billion metric tons of carbon dioxide into the atmosphere annually. Industries are looking for ways to offset their emissions...
Globotruncana falsostuarti -- a foram that lived about 75 million years ago, during the Cretaceous Period, from southeastern Tanzania. By measuring the chemistry in the shell, scientists can estimate...

How do plants respond to rising CO2 levels? To find out, plant physiologist Bert Drake at SERC exposed marsh plants near the Chesapeake Bay to CO2 levels expected in 50 and 100 years. Different...
Compare the healthy coral on the left with the bleached coral on the right. Increased water temperatures caused the bleached coral to lose the microscopic algae that give the coral color and provide...

It’s hard not to identify with penguins as they waddle about upright on land, clad in their tuxedo-like plumage. In their crowded breeding colonies, they squabble with and show off to their neighbors...
At the ends of the Earth, life thrives despite extreme conditions. In the Arctic and Southern Oceans, organisms have evolved adaptations to cope with year-round cold and six months of darkness. But...
Tiny plant-like organisms called zooxanthellae live in the tissues of many animals, including some corals , anemones, and jellyfish , sponges, flatworms, mollusks and foraminifera . These microscopic...
Over a 10-year period NOAA scientists have collected 72,000 seawater samples, and their data show that the ocean is becoming more acidic because of climate change -caused warming. That small shift is...
What can students do to help the ocean? It turns out, a lot! These students from California are among dozens from the U.S. and Mexico who are developing action plans on ocean and climate-related...
The threat that climate change poses to polar bears has received a lot of attention, but they are not the only Arctic species at risk. Ice-loving seals, such as harp, hooded and ringed seals, are...
