Santa Claus isn’t expected to notice smoke. Misty smoke of raging Arctic wildfires has reached the North Pole for the first time in recorded history, and NASA satellites have photographs to prove it. On the sixth of August, NASA’s MODIS, a photographic sensor on the Aqua satellite, captured true-color images of a “vast, thick, acrid […]

Simulations reveal that this deep-sea glass sponge’s skeleton is more than simply pretty A Venus’s flower basket is not all just beautiful. This spectacular deep-sea sponge can also change the circulation of seawater in unusual ways. The sponge’s glassy skeleton is formed by a lacy, barrel-shaped chamber. Flow simulations show how this complex structure changes

According to new study from the University of Alaska Fairbanks, changes in major wind and ocean circulation systems can briefly accelerate or reverse the rate of ocean acidification in the Gulf of Alaska. According to Claudine Hauri, a researcher at the UAF International Arctic Research Center, ocean acidification is typically viewed as a slow push

A study done by the University of Queensland discovered that increasing reforestation efforts in coastal areas could considerably reduce the amount of sediment runoff reaching coral reefs and enhance their resilience. The research project examined over 5,500 coastline coastal locations around the globe and discovered that almost 85 percent of them leached silt to coral

The map displayed above illustrates the locations of the world’s major volcanoes. The Tamu Massif, which is located on the Shatsky Rise in the northwest corner of the Pacific Ocean, has the greatest mass and footprint. Mauna Kea, located on the Hawaiian island of Oahu, has the largest height from base to peak. Ojos del

Mount Rainier towers over Seattle’s growing suburbs and Tacoma, Washington, rising more than 3 miles (14,410 feet) above sea level. Over the course of a year, about two million visitors explore Mount Rainier National Park to see the volcano, glaciers, forested ridges, and alpine meadows. The volcano’s elegance, though, is deceiving. Mount Rainier is considered

Scientists must employ numerous tools to listen to and see activity inside a volcano in order to keep a watch on it. The USGS Volcano Hazards Program monitors volcanoes for signals of change that indicate volcanic reawakening. Surveillance must include several observations (earthquakes, ground activity, volcanic gas, rock chemistry, water chemistry, remote satellite analysis) on

Around 19 million years ago, something horrible happened to sharks. Fossils amassed from sediments in the Pacific Ocean reveal a previously unidentified and shocking shark extinction event. During this event, the populations of the predators abruptly dropped by as much as 90 percent, researchers report in the journal Science on June 4. Furthermore, researchers do not know

In grade school, Charles DeLisi had his first indication of changes in the environment. He lived in a very wooded area, with trees filling his neighborhood, which was very fortunate since he loved to play in the forest. However, one of the saddest events of his adolescence, as he describes, occurred around the time he
The Italian island of Sicily may have registered the highest temperature ever recorded in Europe – 48.8C (119.8F) Regional authorities reported the reading, which the World Meteorological Organization (WMO) needs to verify, near Syracuse on Wednesday. According to the WMO, the present official record in Europe is 48ºC, registered in Athens, Greece, in 1977. The
