Ceremony Marks Latest 7MW Expansion of Dalton Solar Plant

Leaders from Georgia Power, Southern Wholesale Energy, United Renewable Energy LLC and Dalton Utilities gathered this past week for a ribbon-cutting ceremony to mark the latest expansion of the Dalton Solar Plant in Dalton, Ga. With more than seven megawatts (MW) of new generation capacity, this expansion adds to the approximately 700 kilowatts from two previous phases, which came online in 2011 and 2012, respectively.

Study Estimates Quantity and Form of Organic Carbon Exported by Rivers to the Ocean

Humans concerned about climate change are working to find ways of capturing excess carbon dioxide (CO2) from the atmosphere and sequestering it in the Earth. But Nature has its own methods for the removal and long-term storage of carbon, including the world's river systems, which transport decaying organic material and eroded rock from land to the ocean.

Mining Activities Affect Genetic Diversity of Brown Trout in South West England

Pollution from historic mining activities in south west England has led to a reduction in genetic diversity of brown trout according to new research from the University of Exeter. The findings, which will be published on Friday 15 May in the journal Evolutionary Applications, indicate that human activity can alter the genetic patterns of wild populations - an important issue in modern conservation.

Actual SOA Particles are Highly Viscous Semi-Solids Having Complex Compositions and Multifaceted Structures

For the past 20 years, a large portion of the particles measured in the atmosphere were missing from models. At best, models were able to explain one-tenth of the carbon-rich secondary organic aerosols, or SOA, measured in the air. The problem turned out to be a series of fundamental assumptions used in the models due to a lack of experimental data.

Monitoring 'Chinook' Winds May Help Prepare for Large Changes in Wind Energy Output

The Rocky Mountains certainly aren't known for their mild winters. But in contrast to the upper Midwest, which seems to exist in a perpetually frozen state from November through March, the plains just east of the Rockies do get an occasional reprieve from the bitter cold: the Chinook winds.

European Trees Increase Water-Use Efficiency Due to Increased Atmospheric CO2 Concentrations

Increased atmospheric CO2 concentrations have already caused large-scale physiological responses of European forests. In particular, the efficiency of water-use of trees, which is coupled to the uptake of CO2 during photosynthesis of leaves and needles has changed significantly.

Researchers Discover How Abrupt Global Warming Event Triggered Highly Corrosive Deep-Water Current

Around 55 million years ago, an abrupt global warming event triggered a highly corrosive deep-water current through the North Atlantic Ocean. The current's origin puzzled scientists for a decade, but an international team of researchers has now discovered how it formed and the findings may have implications for the carbon dioxide emission sensitivity of today's climate.
