Large quantities dust from the deserts of the Middle East can settle on the Tibetan Plateau, darkening the region's snowpack and accelerating snow melt. A new atmospheric modeling study suggests that, in some years, heavy springtime dust deposition can set off a series of feedbacks that intensify the Indian summer monsoon. The findings could explain a correlation between Tibetan snowpack and the Indian monsoon first observed by British meteorologist Henry Blanford in 1884.
Tropical Cyclone Gaja continued to track toward a landfall in southeastern India when NASA-NOAA's Suomi NPP satellite flew over the Bay of Bengal and provided a visible image of the storm.
In 2011, researchers proposed that artificial guide stars could be used to measure the Earth's magnetic field in the mesosphere. An international group of scientists has recently managed to do this with a high degree of precision. The technique may also help to identify magnetic structures in the solid Earth's lithosphere, to monitor space weather, and to measure electrical currents in the part of the atmosphere called ionosphere.
Up to 15 million hectares of the Brazilian Amazon is at risk of losing its legal protection, according to a new study from researchers at Chalmers University of Technology and KTH Royal Institute of Technology, Sweden, and the University of Sao Paulo, Brazil. This is equivalent to more than 4 times the entire forest area of the UK.
The Atacama Desert, the driest and oldest desert on Earth, located in northern Chile, hides a hyper-arid core in which no rain has been recorded during the past 500 years. But this situation has changed in the last three years: for the first time, rainfall has been documented in the hyper-arid core of the Atacama and, contrary to what was expected, the water supply has caused a great devastation among local life.
New research suggests that, over time, less phosphorus fertilizer may be necessary on agricultural fields.
People living in colder regions with less sunlight consume more alcohol and experience more alcoholic liver disease.
Companies that fail to curb their carbon output may eventually face the consequences of asset devaluation and stock price depreciation, according to a new study out of the University of Waterloo.
The fifth-leading risk factor for mortality worldwide, air pollution presents a major heart health risk. A simple intervention could help people breathe easier at home.
Many people see the carbon cycle as vertical -- CO2 moving up and down between soil, plants and the atmosphere. However, new Michigan State University research published in the current issue of Geophysical Research Letters, adds a dimension to the vertical perspective by showing how water moves massive amounts of carbon laterally through ecosystems -- especially during floods. These findings -- which analyzed more than 1,000 watersheds, covering about 75 percent of the contiguous US -- have implications for climate change and water quality.
