Severe water stress likely in Asia by 2050
Economic and population growth on top of climate change could lead to serious water shortages across a broad swath of Asia by the year 2050, a newly published study by MIT scientists has found.The study deploys detailed modeling to produce what the researchers believe is a full range of scenarios involving water availability and use…

Should we be feeding food waste to livestock?
Food waste is a huge global problem. About a third of the food produced globally for human consumption, approximately 1.3 billion tons each year, is wasted or lost, according to the U.N. Food and Agriculture Organization (FAO). Food losses in industrialized countries add up to roughly $680 billion, with $310 billion in losses in developing countries. Produce (fruits…

Are we what we eat?
In a new evolutionary proof of the old adage, 'we are what we eat', Cornell University scientists have found tantalizing evidence that a vegetarian diet has led to a mutation that — if they stray from a balanced omega-6 to omega-3 diet — may make people more susceptible to inflammation, and by association, increased risk…

Shrinking Arctic ice is impacting Greenland melting
Vanishing Arctic sea ice. Dogged weather systems over Greenland. Far-flung surface ice melting on the massive island. 'Blocking-high' pressure systems spawn most of the warming that melts Greenland surface ice, Rutgers study saysThese dramatic trends and global sea-level rise are linked, according to a study coauthored by Jennifer Francis, a research professor in Rutgers University's Department…

Ocean temperatures predict U.S. heat waves
The formation of a distinct pattern of sea surface temperatures in the middle of the North Pacific Ocean can predict an increased chance of summer heat waves in the eastern half of the U.S. up to 50 days in advance.The pattern is a contrast of warmer-than-average water coming up against cooler-than-average seas. When it appears,…

Sea level rise and its potential impact to Norfolk, Virginia studied by Sandia Labs
In Norfolk, Virginia, an East Coast city that’s home to the world’s largest naval station and important seaports, catastrophic flooding could damage more than homes and roads. A new study from Sandia National Laboratories assesses how much the city, its region and the nation would suffer in damages to national assets and lost economic activity…

The past, present and future of African dust
So much dust is scattered across the planet by the winds of the Sahara that it alters the climate. However, the emission and transport of this dust, which can reach the poles, fluctuate considerably. Although many hypotheses have been put forward to explain this phenomenon, no unambiguous relationship between this dust and the climate had…

Human impact on Earth's global energy
The impact humans have made on Earth in terms of how we produce and consume resources has formed a 'striking new pattern' in the planet's global energy flow, according to researchers from the University of Leicester.The research suggests that Earth is now characterised by a geologically unprecedented pattern of global energy flow that is pervasively…

As EV sales slow, focus shifts for some to heavy duty vehicles
Low gasoline prices and continuing performance issues have slowed the growth of electric car sales. But that has not stymied progress in electrifying larger vehicles, including garbage trucks, city buses, and medium-sized trucks used by freight giants like FedEx.The clang of garbage cans will still probably wake people way too early in the morning. But…

New research on the Rio Grande and impacts of long drought
New research can help water managers along the Rio Grande make wise decisions about how to best use the flow of a river vital for drinking water, agriculture and aquatic habitat. These studies also show how conditions from the prolonged drought in the West have affected the Rio Grande watershed.The Rio Grande forms the world’s…
