Evergreen Trees at risk in Southwest U.S.

Evergreen trees

A research paper published in Nature Climate Change predicts widespread death of needleleaf evergreen trees (NET) within the Southwest United States by the year 2100 under projected global warming scenarios. The research team that conducted the study, which includes University of Delaware’s Sara Rauscher, considered both field results and a range of validated regional predictions and global simulation models of […]

Wilkes Land Anomaly Continues to Baffle Scientists

Wilkes Land Anomaly

Wilkes Land Anomaly Deep beneath the ice of East Antarctica’s Wilkes Land, an enigmatic mass anomaly has continued to puzzle scientists since its discovery. Located under a 300-mile-wide (480 km) impact crater-like structure, the Wilkes Land Anomaly has fueled numerous theories ranging from an asteroid impact site to the remnants of a lost continent—or even, according to some fringe theories, […]

Cleaning Up China’s Dirty Streets

“The Chinese need to learn that public spaces aren’t garbage dumps”, said Raymond Zhou. During a recent national holiday, visitors dropped a staggering 32 tons of litter in Tiananmen Square in just four days. Beijing’s army of street cleaners rushed in and quickly cleaned up the mess. But large areas of the country don’t have those resources, and by the […]

NASA’s plan to nudge an asteroid

In the sci-fi movie Armageddon, astronauts intercept a killer asteroid heading for Earth, saving mankind. NASA is taking the first step to develop the technology to do just that, by planning a mission to slightly alter an asteroid’s orbit. The mission will also serve as an initial test of a solar-electric propulsion system and other technologies essential for a manned […]

Planet Has More Trees

Planet Has More Trees

The last study showed that the world has about 3 trillion trees.  That is over the estimate of 400 billion in previous studies.  Researchers did a count by actually going out and physically counting trees, using satellite imagery, ground survey, and national forest inventories.  Even though we have lost trees from fires, drought, and insect outbreaks there are still more […]

Antarctica’s Subterranean Ecosystem

Antarctica's Subterranean Ecosystem

Antarctica’s Subterranean Ecosystem is quite interesting. In Antarctica researchers have found an undersea ecosystem under an iceberg that broke away from the Antarctic Peninsula.  They say that Antarctica’s Subterranean Ecosystem has been hidden for over 120 thousand years.  As the iceberg moves it will reveal about 2240 square miles of seafloor that has been hidden from light.  The scientists will […]
