As the planet faces the dawn of a sixth mass extinction, scientists are searching for clues about the uncertain road ahead by exploring how an ancient ecosystem collapsed and bounced back from traumatic upheavals. A new study follows the lengthy collapses and revival of South African ecosystems during one of the “big five” mass extinctions, the Permian-Triassic event, revealing unexpected […]

When you travel to Antarctica you are in for a trip of a lifetime. Because of its location you are required to travel with a government scientific program or have a private expedition take you there. The over 50,000 tourists that travel there every year find the sightseeing and wildlife watching most adventurous. Unless you can sail your own boat, […]

When an El Nino hits, the lives of penguins are in peril. During the 1997 El Nino the penguin population fell by a third. During Climate Change a difference in temperature of at least one degree can be a life and death situation for penguins. Researchers followed a group of about 15 breeding penguins from 1992 to 2010 on the […]

There are five US cities that are at risk of flooding due to rising sea levels. They are Miami, Tampa, Boston, New York City, and New Orleans. Miami’s flooding risk comes not only from the high tides but from the porous limestone that is located under the state and has water seeping up under it. Back in 2017 Hurricane Irma […]

Penguins Relocate, resulting in many other geological changes. The Antarctic Peninsula, one of the fastest-warming regions on Earth, is experiencing significant environmental changes due to rising temperatures. As the ice retreats, both the physical landscape and the region’s delicate ecosystems are undergoing dramatic transformations. A major consequence of this warming is the shifting distribution of penguin colonies. These iconic birds, […]

Scientists have long puzzled over the origins of Earth’s vast oceans. Now, new data from the Rosetta spacecraft appear to have crossed one potential source off the list: comets. Rosetta has been in close orbit around comet 67P/Churyumov- Gerasimenko since August, analyzing its chemical makeup. Among the mission’s goals was to determine if the water locked in the comet’s icy […]

Over 15 years of observational data collected by NASA’s Chandra X-Ray Observatory and the Australia Telescope Compact Array have given us a composite image of a tremendous cosmic blast. The image depicts an x-ray beam (blue) casts away from the black hole sitting at the center of Pictor A, a galaxy located 500 million light years from Earth. Other prominent […]

Antarctica and Greenland are shedding their ice sheets at record rates. The warming of the ocean waters is essentially causing the ice sheets to self-destruct and start to collapse. With this ice melting the sea levels may rise to about 6 inches by the year 2100 which is estimated to be more than previously predicted. Antarctica is suggested to be […]

New data suggests there may be two undiscovered planets lurking on the outer fringes of our solar system. Astronomers at the Complutense University of Madrid have detected curious abnormalities in the orbits of a belt of icy rocks at the edge of the solar system, far beyond the orbit of Neptune, the eighth and final known planet. (In 2006, Pluto […]

Just before Christmas… November 1915, while camping on the thawing ice of the Weddell Sea, Shackleton and his men saw their ship, Endurance, going down into the waters of this sea. “She’s going, boys!” Shackleton shouted the evening of November 21, 1915. “She went down bows first, her stern raised in the air. She then gave one quick dive and […]
