New Studies Find Global Warming Will Have Significant Economic Impacts on Florida Coasts

25.09.2008
Leading Florida-based scientific researchers released two new studies today, including a Florida State University report finding that climate change will cause significant impacts on Florida’s coastlines and economy due to increased sea level rise.

A second study by researchers at Florida Atlantic University recommends that the state of Florida adopt a series of policy programs aimed at adapting to these large coastal and other impacts as a result of climate change. Key findings of the FAU report were included just this week by Florida Gov. Charlie Crist’s Climate and Energy Action Team when it adopted the “Adaptation” section of its final report.

“The impacts of climate change on Florida’s coasts and on our economy will be substantial, persistent and long-term, even under our conservative estimates,” said Julie Harrington, director of the Center for Economic Forecasting and Analysis at FSU. “Should, as many models predict, sea level rise, and hurricane strength and other factors become more extreme, much greater economic impacts will occur along many parts of Florida’s coast in this century.”

The second new study, by researchers at FAU, focused on state adaptation policies needed as Florida faces the impacts of climate change.

“The goal of our study is to help the state of Florida adapt, in the most effective way possible, to climate change impacts that are now inevitable,” said Jim Murley, director of Florida Atlantic University’s Center for Urban and Environmental Solutions and leader of the study. “These approaches must be comprehensive and strategic, not piecemeal and episodic. Governor Crist and other leaders have rightly identified adapting to climate change as one of the state’s greatest challenges -- we look forward to working with the state to protect our people, natural splendor, and economic livelihood. There is real work to be done.”

This research was supported by a grant from the National Commission on Energy Policy, a project of the Bipartisan Policy Center.

About the FSU study:

This study uses current estimates of sea level rise from Florida State University’s Beaches and Shores Resource Center and 2001 estimates from the Intergovernmental Panel on Climate Change to evaluate the effect of sea level rise on the six coastal counties. The results show projected trends in storm-surge flood return periods associated with hurricanes, damage costs associated with flooding from major storm events, and the value and area of land at risk.

Under the FSU study’s estimates for sea level in Dade County, the value of land at risk totals $6.7 billion in 2080 (in 2005 dollars). (By comparison, using International Panel on Climate Change sea level estimates, the value of land at risk in Dade County ranges from $1 billion to $12.3 billion in 2080). The study also calculated the effect of storm surge and sea level rise on future damage costs, finding that if a storm like Hurricane Wilma from 2005 occurred in 2080, the cost to Dade alone would be from 12 percent to 31 percent higher (in 2005 constant dollars). While these findings do not account for adaptive strategies or potential future increases in property values, they still provide valuable information about potential impacts and resources that are put at risk from sea level rise.

About the FAU study:

Key findings of the report have been included by Gov. Crist’s Climate and Energy Action Team as it adopted the “Adaptation” section of its final report this week in Tallahassee. Important findings from the FAU study call for major state environmental, growth management and public infrastructure decision-making processes to be adjusted so they are responsive to future climate change impacts.

“FAU will continue to research how Florida can be a leader in providing guidance to other states on how best to put in place workable solutions that will help communities adapt to future climate change impacts,” Murley said.

“Storm events associated with certain levels of storm surge could increase in frequency in the future, due to sea level rise,” Harrington said.

“As sea level rises, damage costs associated with extreme storm events increases significantly for the Florida counties examined in this study,” she said.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
