El Niño is a recurring climate pattern characterized by warmer than usual ocean temperatures in the equatorial Pacific. Two back-to-back 3-D visualizations track the changes in ocean temperatures and currents, respectively, throughout the life cycle of the 2015-2016 El Niño event, chronicling its inception in early 2015 to its dissipation by April 2016.
A new study led by researchers at the University of Wisconsin-Madison examined why private-land conservation data is sometimes inaccessible and found that limited capacity within some federal agencies as well as laws prohibiting others from disclosing certain information are to blame.
A new Tel Aviv University study finds the sedimentation of asymmetric objects in liquid is very different from that of symmetrical objects like spheres. The research may have practical applications in improving water treatment and industrial processes.
In summer 2010, Los Angeles was losing about 100 gallons of water per person per day to the atmosphere through the evaporation and plant uptake of lawns and trees. Lawns accounted for 70 percent of the water loss, while trees accounted for 30 percent, according to a University of Utah study published in Water Resources Research.
Over the past century, the Northeast has experienced an increase in the number of storms with extreme precipitation. A Dartmouth-led study finds that the increase in extreme Northeast storms occurred as an abrupt shift in 1996, particularly in the spring and fall, rather than as a steady change over several decades. The findings were published in an early online release of the American Meteorological Society's 'Journal of Hydrometeorology.'
The frost-free season in North America is approximately 10 days longer now than it was a century ago. In a new study, published today in Nature Communications, researchers from the University of Utah and the US Geological Survey parse the factors contributing to the timing of frost in the United States. Atmospheric circulation patterns, they found, were the dominant influence on frost timing, although the trend of globally warming temperatures played a part as well.
Evidence from the age of the dinosaurs to today shows that chemical weathering of rocks is less sensitive to global temperature, and may depend on the steepness of the surface. The results call into question the role of rocks in setting our planet's temperature over millions of years.
Laser-induced graphene made from an inexpensive polymer is an effective anti-fouling material and, when charged, an excellent antibacterial surface.
A nationwide analysis of water use over the past 30 years finds that there is a disconnect between rural and urban areas, with most urban areas becoming more water efficient and most rural areas becoming less and less efficient over time.
Algal blooms deplete oxygen in lakes, produce toxins, and end up killing aquatic life in the lake. Researchers are tracing the role of bird feces, which are rich in phosphorus and nitrogen.
