ancient-warmingJuly 5, 2016 - A new reconstruction of Antarctic ocean temperatures around the time the dinosaurs disappeared 66 million years ago supports the idea that one of the planet's biggest mass extinctions was due to the combined effects of volcanic eruptions and an asteroid impact.

Two University of Michigan researchers and University of Florida colleague Andrea Dutton found two abrupt warming spikes in ocean temperatures that coincide with two previously documented extinction pulses near the end of the Cretaceous Period. The first extinction pulse has been tied to massive volcanic eruptions in India, the second to the impact of an asteroid or comet on Mexico's Yucatan Peninsula.

Both events were accompanied by warming episodes the team found by analyzing the chemical composition of fossil shells using a recently developed technique called the carbonate clumped isotope paleothermometer.

201606um-wetlandsJune 28, 2016 (Source: UM RSMAS) - As Louisiana’s wetlands continue to disappear at an alarming rate, a new study has pinpointed the man-made structures that disrupt the natural water flow and threaten these important ecosystems. The findings have important implications for New Orleans and other coastal cities that rely on coastal wetlands to serve as buffer from destructive extreme weather events. Scientists at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science found that man-made canals limit the natural tidal inundation process in roughly 45 percent of the state’s coastline, and disruptions from levees accounted for 15 percent. “This study demonstrates that human infrastructure development along coastal areas have long-term consequences on the ability of coastal wetlands to adapt to sea-level rise and other processes that reduce the size of coastal wetlands,” said Talib Oliver-Cabrera, the study’s first author and a UM Rosenstiel School Ph.D. student.

201606fsu-paleoJune 22, 2016 - A major climate event millions of years ago that caused substantial change to the ocean’s ecological systems may hold clues as to how the Earth will respond to future climate change, a Florida State University researcher said.

In a new study published in Earth and Planetary Science Letters, Assistant Professor of Geology Jeremy Owens explains that parts of the ocean became inhospitable for some organisms as the Earth’s climate warmed 94 million years ago. As the Earth warmed, several natural elements — what we think of as vitamins — depleted, causing some organisms to die off or greatly decrease in numbers.

The elements that faded away were vanadium and molybdenum, important trace metals that serve as nutrients for ocean life. Molybdenum in particular is used by bacteria to help promote nitrogen fixation, which is essential for all forms of life.

“These trace metals were drawn down to levels below where primary producing organisms, the base of the ocean food chain, can survive,” Owens said. “This change inhibited biology.”

201606uf-cattle.jpgJune 22, 2016 - University of Florida Institute of Food and Agricultural Sciences researchers hope to reduce possible pollutants emanating from soils in Florida cattle ranches by using a $710,000 USDA grant to study soil microbes.

In the new study, UF/IFAS researchers will use lab and field studies to investigate how pasture management and factors such as temperature and rainfall affect soil microbes. They’ll also look for genetic markers to get a glimpse into microbial identity. Genetic markers are genes or short sequences of DNA scientists use to find other genes on a genetic map.

“The goal is to put together a model that can predict the release of greenhouse gases like carbon dioxide and nitrous oxide from soils under a climate that is expected to be warmer and experience more extreme dry and wet periods across the Southeast,” said Stefan Gerber, a UF/IFAS assistant professor in soil and water sciences and one of the investigators on the new study.

Greg KikerMay 2, 2016 - In May 2016, Professor Greg Kiker, Department of Agricultural & Biological Engineering at UF, will visit the University of Oxford Environmental Change Institute (Oxford-ECI) and its research partners, as the first FCI UF-UK fellow, to establish a framework to integrate models from Oxford-ECI and UF into more localized household-scale models for analysis in six countries in Africa and Southeast Asia.  This collaboration will help UF, Oxford and the International Livestock and Research Institute (ILRI) to focus research and outreach towards sustainable livestock systems.  Dr. Kiker will work with Drs. John Ingram, Steven Lord, Joost Vervoort and Ariella Helfgott (Oxford-ECI) to translate recently developed climate change scenarios and household vulnerability research into both conceptual frameworks and computational models for west and east Africa. This effort is part of the newly established Feed the Future Innovation Lab for Livestock Systems at UF to focus research and outreach towards sustainable livestock systems.

Food systems exist in an increasingly unpredictable and inequitable world as climate drivers and market dynamics do not often align for the benefit of local livelihoods. Livestock sectors also share this challenge as increasing international demand for livestock products does not translate to increased growth opportunities at the household level.

April 25, 2016 - With a $5,000,000 grant from the National Science Foundation, Florida International University will establish the Center for Aquatic Chemistry and the Environment (CREST). The 5-year project will be led by Todd A. Crowl. Additional researchers are Rudolf Jaffe, Rene M. Price, Shu-Ching Chen, Laird H. Kramer. 

Human-derived environmental contaminants consist of antibiotics and pharmaceuticals, mercury, black carbon, and fossil fuels. These stressors are recognized as having significant effects on ecosystems and biota as well as on human wellbeing. It is critical to understand the biogeochemical processes that govern the fate of these compounds and their impacts on the ecosystem. Center for Aquatic Chemistry and the Environment research will address the sources, transport, transformation and ecosystem responses to contaminants, pollutants and other natural stressors, under changing land-use and environmental conditions.

The Center for Aquatic Chemistry and the Environment will generate significant new knowledge regarding contaminants and pollutants in aquatic environments, as well as produce innovative methodologies for detecting and assessing contaminant quantities and impacts, including the use of molecular detection techniques. The proposed research will advance current efforts on the biological effects, transport, transformation and distribution of contaminants in the environment into new collaborative research areas that investigate the sources and transport of contaminants and pollutants in aquatic systems.

The Center articulates three research subprojects organized around environmental chemistry, biogeochemistry, ecology and data synthesis and modeling as they pertain to regional water resources. The first subproject will advance the effectiveness of approaches for the analysis of traditional pollutants, develop methodologies for the characterization and quantification of previously unknown contaminants and extend the applicability of molecular biology methodologies to assess environmental stressors to aquatic organisms across land-use boundaries. The second subproject uses new sensing techniques to determine biogeochemical cycles including contaminant sources, storage, transport and transformations. The third research subproject develops data analytic methods to enable synthesis across large, complex data sets to allow holistic effects assessment for understanding South Florida's aquatic ecosystem.

The Center for Aquatic Chemistry and the Environment will establish innovative opportunities for students to experience authentic and socially relevant environmental research and foster their development as future STEM professionals.

NAS reportApril 6, 2016 - A new University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science-led study found that Miami Beach flood events have significantly increased over the last decade due to an acceleration of sea-level rise in South Florida. The researchers suggest that regional sea-level projections should be used in place of global projections to better prepare for future flood hazards in the region.

To quantify the flood hazard in Miami Beach, the UM Rosenstiel School researchers analyzed tide and rain-gauge records, media reports, insurance claims, and photos of flooding events on Miami Beach and in Miami since 2006. The insurance claims and media reports helped the researchers pinpoint the date and type of flood events.

“Our results show that the effect of sea-level rise is real and affecting the daily life of people living in low-lying coastal communities, such as Miami Beach,” said Shimon Wdowinski, UM Rosenstiel School research professor of marine geosciences, and lead author of the study.

The results showed that the flooding frequency in Miami Beach has significantly increased after 2006 mainly due to increasing number of high-tide flooding events. The increased flooding frequency coincides with acceleration in the rate of sea level rise in South Florida. The average rate of sea-level rise increased by 6 millimeters per year over the last decade - from 3 millimeters per year before 2006 to 9 millimeters per year after 2006. 

The study’s additional co-authors are Ronald Bray and Ben P. Kirtman from the UM Rosenstiel School; and Zhaohua Wu from Florida State University.

coralApril 4, 2016 - A new study from researchers at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science (RSMAS) found that multiple stressors might be too much for corals. The findings have important implications for the resilience of coral reefs to climate change.

To test the coral’s response to multiple environmental stressors at once, UM Rosenstiel School researchers placed Caribbean branching coral Porites porites in waters with high levels of carbon dioxide (900 parts per million) for two months to mimic high ocean acidification conditions. Following the preconditioning, half of the corals were then subjected to increased water temperatures for two months. Following the five-month period, the researchers analyzed the growth, feeding rates, and photochemical efficiency of their algal symbionts in both groups to understand how they responded to multiple environmental stressors.  Many previous studies have assessed the effects of multiple stressors, but this study is novel because it is the first to precondition corals to high CO2 before exposing them to a thermal bleaching event.

Corals preconditioned to high CO2 levels before the increased temperatures showed 44 percent lower growth rates compared to the group that only experienced a single stress of increased carbon dioxide. The researchers suggest that preconditioning to elevated CO2 worsens coral response to thermal stress, which could potentially exacerbate the effects of climate change stressors on coral reefs.

“This study is similar to what corals will likely experience in nature in the coming decades,” said Erica Towle, a UM alumna and lead author of the study. “The findings improve our understanding of how reefs will respond to climate change in the future.”

NAS reportMarch 29, 2016 - The National Academies of Sciences, Engineering, and Medicine has released a new report titled Next Generation Earth System Prediction: Strategies for Subseasonal to Seasonal Forecasts. The report was prepared by the Committee on Developing a U.S. Research Agenda to Advance Subseasonal to Seasonal Forecasting, which includes FCI co-director Dr. Eric Chassignet (FSU).

Report Description:

As the nation’s economic activities, security concerns, and stewardship of natural resources become increasingly complex and globally interrelated, they become ever more sensitive to adverse impacts from weather, climate, and other natural phenomena. For several decades, forecasts with lead times of a few days for weather and other environmental phenomena have yielded valuable information to improve decision-making across all sectors of society. Developing the capability to forecast environmental conditions and disruptive events several weeks and months in advance could dramatically increase the value and benefit of environmental predictions, saving lives, protecting property, increasing economic vitality, protecting the environment, and informing policy choices.

Over the past decade, the ability to forecast weather and climate conditions on subseasonal to seasonal (S2S) timescales, i.e., two to fifty-two weeks in advance, has improved substantially. Although significant progress has been made, much work remains to make S2S predictions skillful enough, as well as optimally tailored and communicated, to enable widespread use. Next Generation Earth System Predictions presents a ten-year U.S. research agenda that increases the nation’s S2S research and modeling capability, advances S2S forecasting, and aids in decision making at medium and extended lead times.

FIU NIH AwardMarch 23, 2016 - The National Endowment for the Humanities (NEH) has chosen FIU’s History Department in the Steven J. Green School of International and Public Affairs (Green School) as the only Florida recipient of a Humanities in the Public Square grant. The grant funds a series of public events, programs, and conversations showing how the humanities can help us come to terms with the threats to Miami from climate change.

“We need more than science and policy right now,” said project director April Merleaux, environmental history professor at FIU. “With this NEH grant, FIU will be able to share another view of some of today’s most pressing issues. We look forward to engaging our community in these important conversations as we imagine our future in South Florida.”

coralMarch 2, 2016 - Global climate change may actually be setting the stage for greater species diversity in the Pacific Northwest. And that could be both positive and negative, depending on the species.

As the climate changes, scientists have been closely monitoring what happens as more carbon dioxide enters our waterways. In recognition of that issue, Florida State University Assistant Professor of Biological Science Sophie McCoy delved into old experiments that explained species diversity and how different species were competitive with one another. Noticing physical changes in the algae’s skeletal structures, she wanted to see if ongoing ocean acidification — the increase in carbon dioxide in the water — affected species interaction. The answer was yes. “Ocean acidification is promoting competition and no one is dominating,” McCoy said. The research is published today in the journal Proceedings of the Royal Society B.

201602mosquitoFebruary 29, 2016 - An NSF-funded project on the effects of climate, land use, and socioeconomic conditions on vector-borne disease transmission, such as the Zika virus, was featured in an NSF press release recentlyStudying interacting factors allows researchers to understand the "risk landscape" for mosquito-transmitted diseases, according to Sadie Ryan, an ecologist and medical geographer at the University of Florida who is collaborating on the research. Taking a local approach then broadening it, the scientists believe, will allow them to find out when and where interventions -- such as in vector control, healthcare infrastructure, environmental modification, education, and climate change early warning systems -- may be most effective.
