Selected Science Communication

Anna Barnett at Nature wrote a nice piece about our new Science Express article, Settling of dust warms tropical Atlantic, and had blogged about the article in the Nature Climate blog.

There has been some recent press coverage of links between African dust and hurricanes, including New Scientist, Florida Public Radio [audio], Reuters, and Popular Mechanics.

My G-Cubed paper on how African dust outbreaks affect seasonal hurricane activity through ocean temperature modulation was picked up by UPI, and covered in Science Daily, among other outlets.

Nature featured the Evan et al., 2007 GRL article in the Research Highlights [PDF] section of the March 1st edition (446 pp. 4–5).  News @ Nature.com published a longer story online --A cloudy view of cloudiness.

Our 2006 GRL paper on the connections between African dust storms and North Atlantic hurricanes received excellent press cover!  Here is a link to the story from USA Today --Study suggests African dust storms may reduce hurricane frequency-- or you can listen to an interview on Voice of America Radio --Researchers Say West African Dust Storms May Limit Atlantic Hurricanes.

At SAGE, my work with the land-use research group on mapping the global patterns of agriculture was covered by many news outlets.  Read the story written by National Geographic News --Farming Claims Almost Half Earth's Land, New Maps Show.

The JGR study on the interannual variability of West African dust storms was covered in CO2 Science --Winter Dust Activity off the Coast of West Africa
