GAINESVILLE, Fla. — People who live in the southeastern United States should begin to prepare for more drastically changing weather conditions – everything from heat waves to poorer air quality – caused by climate change, according to a new book, edited by a University of Florida researcher.
The book, which UF’s Keith Ingram helped write, is titled “Climate Change of the Southeast United States: Variability, Change, Impacts and Vulnerability.” Ingram was the book’s lead editor.

GAINESVILLE – Renowned scientist Michael Mann will give the keynote address at the 2013 E.T. York Lecture Series Nov.19 at the Emerson Alumni Hall at the University of Florida.
Mann, a distinguished service professor of meteorology at Penn State University, will address the “Hockey Stick and the Climate Wars: Dispatches from the Front Lines.”
In his recent book “The Hockey Stick and the Climate Wars,” Mann discusses his experiences in the center of the climate change debate resulting from a graph he and his co-authors published 15 years ago, demonstrating the unprecedented nature of modern climate change. The line of the graph charted global temperatures over the last 1,000 years, starting to spike upward in about 1850, resulting in a graph that resembled a hockey stick. (more …)
GAINESVILLE — The Florida Automated Weather Network is bigger than ever, with three new sites added this year.
Stations added since April are in Citrus, Okeechobee and Palm Beach counties, said Rick Lusher, manager of the network at the University of Florida’s Institute of Food and Agricultural Sciences.
That makes 41 stations now in the network, built in 1998 to give the state’s agricultural producers the most current weather information possible.

GAINESVILLE, Fla. — University of Florida researchers have found, for the first time, that crop models predicting yields for one of the world’s most important crops begin to disagree under climate change scenarios.
By knowing where those models break down, researchers will be better able to improve them. The computerized models predict crop yields for wheat, one of the world’s most-consumed foods.
Scientists use crop models to foresee which parts of the world may face the greatest food shortages, so that efforts to improve food production can be directed to those places.

GAINESVILLE, Fla. — There is no evidence that pollutants from the 2010 Gulf of Mexico oil spill contributed to the “unprecedented” decline in recent Apalachicola Bay oyster populations, according to a report this week by the University of Florida.
Instead, the report by UF’s Oyster Recovery Team cites drought, insufficient rainfall and increased salinity in the bay as factors contributing to the dramatic drop-off in oyster landings beginning in September 2012 and continuing through the year, said Karl Havens, task force leader and director of Florida Sea Grant.
“There was a whole chain of circumstances that led to this situation, some of which are beyond human control,” Havens said. “Our report makes recommendations for many things that can be done to help the oyster population through management and restoration.”
Havens and other recovery team members discussed the report and findings with a crowd of about 60 residents and seafood workers Wednesday at the Apalachicola Community Center.

GAINESVILLE, Fla. – The University of Florida will host a climate symposium April 2-3 that will feature leading authorities on food, sustainability and climate change.
Registration has closed for the event, but members of the media are welcome to attend. It is being held at the Reitz Student Union on campus. The last two sessions on April 3, from 2 p.m. to 4 p.m., are open to anyone, regardless of registration. For more information, please see agenda here: http://conference.ifas.ufl.edu/landgrant/agenda.pdf.
Called Sustaining Economics and Natural Resources in a Changing World: Key Role of Land-Grant Universities, the symposium will address the impact land-grant institutions and their research have had on food security and agricultural production; infrastructure and transportation; energy; sustainable development and resource policies.

GAINESVILLE, Fla. — Consumed by 3 billion people, rice is arguably the world’s most important food staple, and one reason for its popularity is that rice can be grown under flooded conditions that suppress weeds, making cultivation easier.
In some parts of the world, water is in short supply, but farmers often devote what they can to rice farming, because the crop is so important. However, research has led to a simple but profound solution that requires less water – growing rice in fields, a practice called aerobic rice production.
The practice relies on rainfall plus limited irrigation to meet the plants’ moisture needs. It requires about 40 percent less water than paddy-grown rice, according to a University of Florida study in the current issue of Agronomy Journal.
Aerobic rice production is gaining popularity in India and Southeast Asia, particularly in drought-stricken or upland areas, said Rao Mylavarapu, a professor with UF’s Institute of Food and Agricultural Sciences and one of the study’s authors.

GAINESVILLE, Fla. — Termite control pioneer Nan-Yao Su and climate expert Clyde Fraisse of the University of Florida’s Institute of Food and Agricultural Sciences were honored for their international work this week, receiving a pair of annual awards.
Su, an entomology professor at the Fort Lauderdale Research and Education Center, received the International Fellow Award; Fraisse, an associate professor with the agricultural and biological engineering department in Gainesville, received the UF/IFAS International Achievement Award.
Both were recognized Thursday at a meeting of top UF/IFAS administrators. Jack Payne, UF senior vice president for agriculture and natural resources, and Walter Bowen, director of UF/IFAS International Programs, formally presented the awards.

GAINESVILLE, Fla. — Protecting Florida’s $80 million blueberry crop from freeze damage is always a wintertime challenge, but a University of Florida study shows that structures called high tunnels could shield plants from cold and promote earlier fruit ripening.
Though the initial investment can run from $18,000 to $25,000 per acre plus labor, high tunnels deliver better quality fruit, bigger early yields and higher prices if growers beat competitors to market, said Bielinski Santos, an associate professor with UF’s Institute of Food and Agricultural Sciences.
The study, published in the current issue of HortTechnology, tracked two growing seasons on a commercial blueberry farm in Alachua County. The results showed that temperatures outside the tunnels plunged to freezing or near-freezing 61 times during the study. Temperatures fell that low just three times inside the unheated tunnels.
High tunnels may increase air and soil temperatures and protect the plants from wind and rain damage, leading to better flowering and more fruit, said Santos, based at UF’s Gulf Coast Research and Education Center in Balm.
