Rice University scientists have released the first results of extensive water sampling in Houston after the epic flooding caused by Hurricane Harvey. They found widespread contamination by E. coli, likely the result of overflow from flooded wastewater treatment plants.

The 2014 megafires in Canada's Northwest Territories burned 7 million acres of forest, making it one of the most severe fire events in Canadian history.

NASA's Terra satellite found Tropical Storm Son-Tinh continuing to drop rain over Hainan Island and mainland China.

When carbon dioxide is absorbed by seawater carbonic acid is formed, making the water more acidic. Since the Industrial Revolution, oceanic CO2 has risen by 43% and is predicted to be two and a half times current levels by the end of this century.

Sheltered pockets of cooler and more variable conditions in the British countryside may help native species of flora and fauna survive warming temperatures caused by climate change, researchers have found.

Take a look at the clouds, if there are any in your sky right now. If not, here are a few examples. Watch the billows, the white lofty tufts set against the blue sky. Or, depending on your weather, watch the soft grey edges smear together into blended tones that drag down through the air to the ground.

Colorful, hardened algae that dot the ocean floor from Alaska to Mexico often set the tone for which plant and invertebrate species inhabit a given ecological community.

Tropical Depression 13W formed on July 22 and the next day, NASA's Aqua satellite captured an image of the storm hugging the coast of southeastern China.

Scientists have identified 22 key research questions surrounding the risks associated with chemicals in the environment across Europe.

A first-of-its-kind survey of the world’s sandy shorelines with satellite data found that they have increased slightly on a global scale over the past three decades but decreased in protected marine areas, where many beaches are eroding.

Erosion in protected marine areas could threaten plant and animal species and cultural heritage sites.  Worldwide, the study found that 24 percent of Earth’s sandy beaches are eroding, a coastline distance of almost 50,000 miles.

The view from space provided researchers with a more accurate picture of just how much of Earth’s shorelines are beaches. They found that about a third (31 percent) of all ice-free shorelines are sandy or gravelly. Africa has the highest proportion of sandy beaches (66 percent) and Europe has the lowest (22 percent).
