British Airways Turns Garbage into Jet Fuel: Sustainable Solution or Incineration in Disguise?
Can garbage power your plane ride from New York to London? Thatâ€™s the idea behind a new production plant that will transform waste from London's homes and businesses into a jet fuel that costs about the same price as conventional petroleum-based fuel but burns cleaner and produces fewer carbon emissions. >> Read the Full Article
Trawling: destructive fishing method is turning sea floors to 'deserts'
Bottom trawling is a practice used by commercial fisheries around the world in which a large, heavy net is dragged along the ocean floor to scoop up everything in its path. Previous research has linked trawling to significant environmental impacts, such as the harvest of large numbers of non-target species, collectively termed "by catch," as well as destruction of shallow seabeds. Now, a new study published in Proceedings of the National Academy of Sciences finds this method is also resulting in long-term, far-reaching consequences in the deeper ocean and beyond. Trawling dates back to the 1300s, and it became widespread in coastal areas around the world after the industrialization of commercial fishing in the late-1800s. Bottom trawling targets commercially valuable species that live near the sea floor, such as cod, rockfish, and various kinds of squid and shrimp. Gear varies depending on the fishing outfit, but nets can be nearly as large as a city block and scoop thousands of fish and other marine animals in a single drag. >> Read the Full Article
How Sharks Could Help Predict Hurricanes
Scientists have embarked on a remarkable new project to use shark and large marine predators as biological sensors in the hopes that they could help us predict the formation and course of potentially dangerous hurricanes. Researchers from the University of Miami have tagged a total of 750 marine animals in the past ten years, all to track the temperature and salinity of sea waters at different depths. Earlier this year though, the researchers noticed something special about the data â€” the tagged marine life gravitated toward water that was about 79 degrees Fahrenheit or higher, which is the temperature at which hurricanes form. >> Read the Full Article
EPA doles out grants to replace old diesel engines on tug boats
The shipping industry is one of the most under-regulated industries in the world due to outdated and international regulations that are difficult to enforce on a global scale. And as these ships enter our harbors and ports close to home, their operations have the potential to generate smog-forming emissions and other pollutants that are linked to various health problems in susceptible populations. In an effort to combat some of the pollution expelled from dirty diesel engines, the U.S. Environmental Protection Agency has allotted over one million dollars to help two specific organizations replace their old engines with less polluting models. According to the EPA, the projects will cut emissions of harmful nitrogen oxides and particulate matter among other pollutants which are linked to asthma, lung and heart disease and premature death. >> Read the Full Article
Longer growing season does not yield growth increase for trees and shrubs
As the earth's temperatures rise, some have speculated that trees and shrubs in the colder climates might experience and increase in growth as a result of the extended growing season. "Not so," says a recent study authored by a University of Washington biology and applied mathematics postdoctoral student. Her study demonstrates that bushes achieve less yearly growth when cold winter temperatures are interrupted by warm spurts that trigger growth. >> Read the Full Article
Antarctica dances to Carole King's "The Earth Moves Under My Feet"
Antarctica has apparently been living by the lyrics of Carole King's 1971 hit song "The Earth Moves Under My Feet". According to a study from Newcastle University in the United Kingdom, Antarctica has been moving "rapidly". Recently published in Earth and Planetary Science Letters, the study explains why the upward motion of the Earth's crust in the Northern Antarctic Peninsula is currently taking place so quickly. While earlier studies have shown the earth is 'rebounding' due to the overlying ice sheet shrinking in response to climate change, GPS data is suggesting otherwise. The international research team led in part by Newcastle researchers has revealed that this land is rising at a remarkable rate of 15mm a year. >> Read the Full Article
Reintroducing the European Bison
In a coordinated effort to reintroduce the European bison to the grasslands of southern Romania, the World Wildlife Fund for Nature (WWF) and Rewilding Europe recently brought 20 bison to the Southern Carpathians. Ten more will be reintroduced over the summer. The species has been absent for about 200 years. >> Read the Full Article
"State of the Air 2014" Shows Half the U.S. Lives with Unhealthy Air
Nearly half of all Americans â€“ more than 147 million â€“ live in counties in the U.S. where ozone or particle pollutions levels make the air unhealthy to breathe, according to the American Lung Association's "State of the Air 2014" report released today. The 15th annual national report card shows that while the nation overall continued to reduce particle pollution, a pollutant recently found to cause lung cancer, poor air quality remains a significant public health concern and a changing climate threatens to make it harder to protect human health. >> Read the Full Article
Fighting air pollution with innovation and technology
Air pollution has become one of the world's biggest threats to the future of our planet. Chronic air pollution shortens our lives and the lives of the ecologies around us. In parts of Asia, where air pollution is most pervasive, food crops and other plants are exhibiting signs of stress due to low air quality. >> Read the Full Article
Climate Change on JUPITER
We are very concerned with the changing climate on Earth. The climate on other planets is more difficult to study, and direct observations are impossible, save some observations from the Mars rovers. Jupiter has an atmosphere that is very different from Earth's. The prominent Giant Red Spot, a swirling anti-cyclonic storm larger than Earth, appears to be a permanent fixture of the planet's atmosphere, and has been remarkably stable for decades. Now the Great Red Spot has shrunk to its smallest size ever measured. According to Amy Simon of NASA's Goddard Space Flight Center in Greenbelt, Maryland, recent NASA Hubble Space Telescope observations confirm the Great Red Spot now is approximately 10,250 miles across, less than half the size of some historical measurements. Astronomers have followed this downsizing since the 1930s. >> Read the Full Article
