New Study Links Dust to Increased Glacier Melting, Ocean Productivity

submitted by: UMiami_RSMAS
University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science-led study shows a link between large dust storms on Iceland and glacial melting. The dust is both accelerating glacial melting and contributing important nutrients to the surrounding North Atlantic Ocean. The results provide new insights on the role of dust in climate change and high-latitude ocean ecosystems. UM Rosenstiel School Professor Joseph M. Prospero and colleagues Joanna E. Bullard and Richard Hodgkins...

Opportunities and Challenges of Offshore Wind Energy

submitted by: RASEIBoulder
Offshore wind power can contribute extensively to a clean, robust, and diversified U.S. energy portfolio. Capturing the Nation's large and inexhaustible offshore wind resource has the potential to mitigate climate change, improve the environment, increase energy security, and stimulate the U.S. economy. This seminar provides a broad understanding of the global offshore wind industry today and the associated technology challenges, economics, permitting procedures, and potential risks and...

Can Renewables Provide Big Energy in America's Electric Future?

submitted by: RASEIBoulder
Renewable energy sources currently provide about only about 10% of the nation’s electricity, with most of that coming from large hydro sources. Renewable energy sources are scattered around the country, with much of the best wind and solar resources located in remote locations. These sources also may have a big footprint compared to conventional sources. Finally, solar and wind are often described as intermittent due to their variable and uncertain output. As a consequence, it is often...
