201705rsmas-hurricane.jpgMay 15, 2017 (Source: UM RSMAS) - Researchers believe they have found a new way to monitor the intensity and location of hurricanes from hundreds of miles away by detecting atmospheric waves radiating from the centers of these powerful storms.

In a new study, scientists from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science and the Hurricane Research Division of the National Oceanic and Atmospheric Administration (NOAA) presented direct observations of the waves, obtained by NOAA aircraft flying in hurricanes and by a research buoy located in the Pacific Ocean. The waves, known as atmospheric gravity waves, are produced by strong thunderstorms near the eye and radiate outward in expanding spirals.

“These very subtle waves can sometimes be seen in satellite images,” said David Nolan, professor in the Department of Atmospheric Sciences, and lead author of the study. “We were able to measure them in aircraft data and surface instruments.”

201705uf-Eradication-credit-dany-krom-300x194.jpgMay 10, 2017 (Source: UF) - New research co-authored by USF's Jeremy Cohen, Leah Johnson, and Jason Rohr and UF's Sadie Ryan and Cat Lippi sheds light on the climate suitability for Aedes aegypti and Aedes albopictus mosquitos and transmission rates of Zika, chikungunya, and dengue fever.

The study, published in PLOS Neglected Tropical Diseases compares new data driven models of Zika, chikungunya, and dengue fever transmission to real world measurements of human infections caused by bites from Aedes aegypti and Ae. Albopictus mosquitoes. These models confirm that temperature is the single most important factor for predicting the rate and geographic spread of epidemics of these mosquito-borne diseases. Temperature influences transmissibility in many ways – affecting the lifespan of an individual mosquito, and determining biting frequency and the reproductive rate of the virus within the mosquito.

The collaborative research team includes experts in epidemiology, public health, ecology, mathematical modeling, and geography, and was funded by a grant from the National Science Foundation’s Ecology and Evolution of Infectious Disease program (NSF-DEB 1518681).

newsletter/201705fsu-acidification.jpgMay 3, 2017 (Source: FSU) - Climate change may be putting cyanobacteria that are crucial to the functioning of the ocean at risk as the amount of carbon dioxide in the atmosphere increases and the acidity of ocean water changes. In a paper published in Science, a team of researchers from Florida State University, Xiamen University in China and Princeton University argue that the acidification of seawater caused by rising carbon dioxide levels makes it difficult for a type of cyanobacteria to perform a process called nitrogen fixation. Few people know much about a type of cyanobacteria called Trichodesmium, but this miniscule collection of cells is critical to the health of hundreds of species in the Earth’s oceans. Through nitrogen fixation, Trichodesmium converts nitrogen gas into ammonia and other molecules that organisms are dependent on for survival. Trichodesmium is thought to be responsible for about 50 percent of marine nitrogen fixation, so a decline in its ability could have a major ripple effect on marine ecosystems. “This is one of the major sources of nitrogen for other organisms in the open ocean,” said Sven Kranz, assistant professor of Earth, Ocean and Atmospheric Science at Florida State University and a co-author of this study. “If Trichodesmium responds negatively to the environmental changes forced upon the ocean by fossil fuel burning, it could have a large effect on our food web.”

An Actionable Tool to Map Future Expansion of the Coastal High Hazard Area: Translating Science to Policy in Planning for Sea-Level Rise and Storm Surge in the Florida Keys with a focus on Islamorada, Village of Islands
SFRPC was awarded a grant from the Gulf of Mexico Alliance to create an interactive tool to map surge vulnerability. This study will focus on the Florida Keys’ exposure to sea-level rise, and more importantly, storm surge, using recently released Sea, Lake, and Overland Surges from Hurricane (SLOSH) data modeled at various scenarios. Results will be made available on an interactive website, and there will be a series of stakeholder engagement opportunities.

Trainers and Tools: Building Coastal Flood Hazard Resiliency in Florida’s Regional Planning Council Communities Project: Capacity Building through Technical Assistance and Outreach
This project was created to educate and promote four coastal flood hazard assessment tools: NOAA’s Sea Level Rise Viewer, Coastal Flood Exposure Mapper, and CanVis Tools, as well as FDOT/UF’s Geoplan Sketch Planning Tool. The project was coordinated with regional trainings and vulnerability assessments conducted throughout Florida’s ten regional planning councils. Outcomes included enhanced communication, stakeholder engagement, intergovernmental coordination, and an overall increase in Florida’s adaptive capacity for coastal resilience. For more information, please visit the project webpage.

Improving the Planning Process to Protect Infrastructure from Emerging Coastal Flood Hazards
In producing a series of Infrastructure Protection Resources, SFRPC aimed to provide technical assistance to local governments wishing to increase resilience to coastal flooding, particularly during extreme events such as high tides and storm surge. In the first part of the project, SFRPC documented the process of in situ measurement and modeling of current and projected Fall King Tide flooding in six pilot communities: Dania Beach, Hollywood, North Miami, North Bay Village, Key Largo, and Islamorada. The second set of resources documented structure surveys given to local public works staff, city managers, and other relevant stakeholders, to understand the current state of infrastructure in 6 pilot communities, as well as key challenges and solutions. The final resource, set for completion in June 2017, focuses on one community, North Bay Village. The SFRPC and Village staff plan to prepare and transmit a comprehensive plan amendment(s) which address deficiencies in the Village’s response to Peril of Flood. This amendment will include best available data, including new storm surge data from the Sea, Lake, and Overland Surges from Hurricanes (SLOSH) model to designate the Coastal High Hazard Area.

201704nelson-hearing.jpgApril 11, 2017 - U.S. Sen. Bill Nelson (D-Fla.), the ranking member of Senate Committee on Commerce, Science, and Transportation convened a full committee field hearing titled “Extreme Weather and Coastal Flooding: What is Happening Now, What is the Future Risk, and What Can We Do About It?”on Monday, April 10, 2017 at 1:30 p.m. EDT in West Palm Beach, Florida.

The hearing examined the impacts of sea level rise and extreme weather events.  Since 2006, sea level rise in southeast Florida has tripled, averaging about nine millimeters a year.  The resulting impacts of coastal flooding, saltwater intrusion, storm surge, and land erosion on Florida’s coastal communities have prompted local governments to act.  Following Hurricane Sandy, Palm Beach County restored over 20 acres of beach and sand-dunes to protect shoreside communities from flooding and severe weather. Sen. Nelson led a discussion on the economic impacts of extreme weather and coastal flooding to communities, as well as future risks and efforts to address the problems.

The field hearing included 2 witnesses from the Florida Climate Institute: Dr. Ben Kirtman (UM) and Dr. Len Berry (Coastal Risk Consulting; FAU). The full witness testimonies are available at the hearing webpage link below.

201704uf-rainforest.jpgApril 10, 2017 (Source: Brett Scheffers) - Dispersal has become one of the most studied traits in ecology and conservation as scientists attempt to understand species distributions and species resilience to environmental instability. A paper led by Brett Scheffers (UF) and recently published in Global Ecology and Biogeography presents a new trait associated with resilience to environment instability—arboreality.

Here, the authors show that vertical (arboreality) and horizontal (dispersal) movement are closely linked and together they increase the resilience of vertebrates to climatic instability in the wet tropical rainforests of Australia.

The authors also present a new climate dimension to biogeography—the microclimate created by trees. Here, they monitored temperature from ground to canopy in tropical rainforests across elevation. They show that low- and high-altitude arboreal species experience similar thermal regimes, whereas low- and high-altitude ground-dwelling species experience little overlap in thermal regimes.

Following the spirit of Janzen’s hypothesis (1967-Mountain passes are higher in the tropics), the researchers found that temperature regimes in canopies are effectively less differentiated across geographical space than on the ground due to greater overlap in hot thermal regimes in the canopy. As such, arboreality (and its strong interaction with horizontal dispersal) may be a critical trait mediating the extinction proneness of species to past and future environmental instability.

201704fiu-leaflitter.pngMarch 30, 2017 (Source: FIU) - The carbon dioxide coming from some of Earth’s tiniest residents may not be increasing as quickly as some believed in the face of global climate change. Streams and rivers are home to insects, bacteria and fungi that consume plant litter, including fallen leaves, and break it into smaller pieces. This type of litter is good for streams and rivers because it helps remove toxins. As leaf litter is consumed, insects and microbes get oxygen, convert nutrients into energy and release carbon dioxide into the atmosphere. This process is what scientists call leaf litter decay.

According to a recently released study, temperature is not the only factor in how quickly insects and micro-organisms convert their food into energy and, as a byproduct, release carbon dioxide into the air. This finding contradicts a long-held belief that this process would accelerate with rising temperatures. Understanding how plant matter breaks down in different environments can help scientists predict how ecosystems will respond to climate change.

“If you have a reliable source of energy for organisms in an ecosystem, like the energy provided by consuming leaf litter, the communities of animals and plants living there will be more persistent,” said John Kominoski, an FIU biologist and co-author of the study. “Since global temperatures are rising and leaf litter decay is not as sensitive to temperature as once believed, it gives us hope ecosystems won’t be as energy-limited as we had thought.”

201704troxler.pngMarch 28, 2017 - The National Academies of Sciences, Engineering, and Medicine has appointed a committee of experts, including Tiffany Troxler of FIU, to conduct a study on Developing a Research Agenda on Carbon Dioxide Removal and Reliable Sequestration.

Reaching lower global temperature targets recently set by the international community to avoid climate risks may require removing greenhouse gas that's already accumulated.  However, many of the proposed carbon dioxide removal (CDR) technologies are not yet viable in terms of cost and scalability, and any potential risks are not fully understood.

This study will develop the detailed research and development agenda needed to assess the benefits, risks, and sustainable scale potential for CDR and sequestration approaches and increase their commercial viability. Approaches considered will include land management, accelerated weathering, bioenergy with capture, direct air capture, geologic sequestration, and blue carbon, among others.

The committee slate is provisional pending a public comment period and final approval by the National Academies.

201702fiu-everglades.jpgFebruary 22, 2017 (Source: FIU) - Researchers are taking a step back to answer the question whether long-term studies are helping save plants, animals and the places they call home. The global answer is yes. FIU researchers are gathering data in the Florida Everglades that provide critical information needed for restoration and conservation. They’ve been doing this for more than a decade.

The Everglades is made up of different ecosystems, including swamps, hardwood hammocks, mangrove forests, pine rocklands and sawgrass marshes. Their interconnectivity makes them especially susceptible to changes in the environment.

FIU’s long-term approach to studying the Everglades allows scientists to understand how it works, and it allows them to predict how it will respond to changes in the future. For more than 16 years, scientists in FIU’s Florida Coastal Everglades Long Term Ecological Research (FCE LTER) Program have been studying how water, climate and people affect the Everglades. Their efforts have resulted in more than 500 peer-reviewed journal articles to date.

In a new paper, FIU researchers outline the value of international long-term research, how it has played into what is known about the Everglades and other wetlands, and how it can help solve current and future ecological problems. It is part of a four-paper special feature on international long term ecological research published in Ecosphere.

newsletter/201703rsmas-hurricane.pngFebruary 15, 2017 (Source: UM/RSMAS) - Last year’s devastating category-5 hurricane—Matthew—may be one of many past examples of a tropical storm fueled by massive rings of warm water that exist in the upper reaches of the Caribbean Sea.

In a study conducted in the region two years prior to when Matthew’s trekked across the Caribbean Sea, the research team in the Upper Ocean Dynamics Laboratory at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science (RSMAS) deployed 55 aircraft ocean instruments from the National Oceanographic Atmospheric Administration’s WP-3D aircraft. The purpose of the scientific mission was to measure ocean temperature, salinity, and currents to understand the structure of these warm-water eddies.

The science team obtained vital information about the physical characteristics within one large warm-water eddy, which likely originated from the North Brazil Current, and analyzed its potential influence on sub-surface ocean conditions during the passage of tropical cyclones.

When analyzing the data they found a barrier layer, an upper ocean feature created by the Amazon-Orinoco freshwater river outflow, that makes mixing in the upper ocean waters less efficient during wind events. This feature, and the fact that warm ocean eddies are known to assist in the intensification of hurricanes due to deep warm thermal layers, lead the researchers to theorize that the barrier layer within a warm ocean eddy may result in an even more favorable upper ocean environment for hurricane intensification.

“Our study is important because tropical cyclone intensity forecasts for several past hurricanes over the Caribbean Sea have under-predicted rapid intensification events over warm oceanic features,” said Johna Rudzin, a PhD student at the UM Rosenstiel School and lead author of the study.

201702fsu-spencer.jpgFebruary 13, 2017 (Source: FSU) - A Florida State University researcher is delving into the complexities of exactly how permafrost thawing in the Earth’s most northern regions is cycling back into the atmosphere as carbon dioxide and further fueling climate change. Answer: It has a lot to do with tiny little bugs called microbes and little to do with sunlight.

Assistant Professor of Earth, Ocean and Atmospheric Science Robert Spencer and a team of researchers traveled to Siberia from 2012 to 2015 to better understand how thawing permafrost affected the carbon cycle. They specifically investigated how the vast amounts of carbon stored in this permafrost transferred to the atmosphere as carbon dioxide.

In a paper published in the American Geophysical Union’s Journal of Geophysical Research-Biogeosciences, Spencer along with Aron Stubbins from the University of Georgia explain that bacteria — or microbes — were the dominant consumer of this carbon. They are gobbling up the carbon from the thawing permafrost and spitting it back out as carbon dioxide. This is in contrast to sunlight, which could also break down the carbon and turn it into carbon dioxide. In their study, researchers found sunlight converted little if any permafrost thawed carbon to carbon dioxide, whereas microbes were shown to rapidly convert permafrost carbon to carbon dioxide.
