The article, “Direct human influence on atmospheric CO2 seasonality from increased cropland productivity,” is first authored by Gray and discusses Gray’s and Friedl’s research on how crop production influences the carbon cycle.
The article has also been featured in multiple news articles published recently.
A summary of the research can be found on Nature News and Views, and direct quotes from Friedl and Gray on their research can be found on Science 2.0, Nature World News, and The Christian Science Monitor.

Earth and Environment PhD student Jian Bi and Prof. Ranga Myneni coauthored an article in the Proceedings of the National Academy of Sciences of the USA entitled “Vegetation dynamics and rainfall sensitivity of the Amazon” together with colleagues from NASA and Oregon State University.
This article reports that since the year 2000, precipitation has declined across 69% of the tropical evergreen forest (5.4 million km2) and across 80% of the subtropical grasslands (3.3 million km2). These reductions, which coincided with a decline in terrestrial water storage, account for about 55% of a satellite-observed widespread decline in the normalized difference vegetation index (NDVI).

Earth & Environment Associate Professor Sergio Fagherazzi has coauthored a new paper in the Journal of Geophysical Research Earth Surface.
The article, “Interactions between barrier islands and back barrier marshes affect island system response to sea level rise: insights form a coupled model,” was published in the 119th volume and 9th issue of the journal.
The article is available online here.
Earth and Environment Professor Ranga Myneni coauthored a paper in Nature Communications with a multi-national group of researchers on the weakening relationship between vegetation photosynthetic activity and temperature in the northern latitudes.

Myneni was recently named to the Thomson Reuters Highly Cited Researchers 2014 list; he specializes in vegetation remote sensing with satellite data and climate-vegetation interactions. To learn more about Professor Myneni, check out his profile.
The paper, “The Potential Predictability of Precipitation Occurrence, Intensity and Seasonal Totals over the Continental United States,” was published in September and can be accessed online.
The study breaks the variability of precipitation into “weather” and ”climate” components and finds that most of the opportunity for seasonal climate prediction lies in precipitation occurrence rather than intensity or seasonal total precipitation.
