“…Much of Brazilian research conducted since Silva et al (2010) has focused on assessing changes in surface winds with respect to present and future wind energy production (Lucena et al, 2010;Pereira et al, 2013;Santos and Silva, 2013;Pes et al, 2017). Lucena et al (2010) showed that future wind energy production should increase for coastal * Correspondence to: J. M.

“…E-mail: jgilli7@lsu.edu and northern Brazil by the end of the 21st century based on Intergovernmental Panel on Climate Change (IPCC) emission scenarios (pessimistic high and optimistic low emissions) and present land-cover using Hadley Centre Coupled Model, version 3 (HadCM3; Gordon et al, 2000) general circulation model. Pereira et al (2013) stimulated future wind energy using HadCM3 model and concluded that energy production should also increase for northeastern Brazil by the end of the 21st century. However, their analysis further explored past wind records from 15 Brazilian weather stations and established that the majority (11) of sites is experiencing decreasing or non-significant linear wind speed trends from 1960 to 2007.…”

This study examines the spatial and temporal surface (10 m) wind speed trend characteristics of Brazil during 1980-2014 using two in situ and three climate reanalysis datasets. Nonparametric regression is used to understand how mean seasonal and annual wind speeds change over space and time across Brazil. Overall temporal linear trends show that station and reanalysis products exhibit varying seasonal and annual wind speed trends. A geographic examination displays statistically significant (P < 0.05) positive (negative) mean wind speed trends for equatorial (southeastern and central) Brazil. Quantile regression is performed to interpret how wind speed changed across different percentiles. Results show that the largest positive and negative spatial wind speed trends occur for the upper percentiles (75 and 95%). The spatial and temporal trends and correlations described could be interconnected to possible changes developing with the location of Intertropical Convergence Zone and South Atlantic Anticyclone over the study region. Results have implications for optimizing renewable wind energy production and development across Brazil.

“…Their findings also predicted an increase in the frequency of high wind speeds in coastal areas, forecasting a favourable outlook for offshore wind project development. Pereira et al [22] also found a slight improvement of the Brazilian wind resource under the SRES A1B forcing scenario, particularly in the north-eastern area, where some regions were predicted to see a doubling of wind power density from historical values.…”

Climate-forced changes in atmospheric circulation patterns can pose challenges to the development of an efficient wind energy industry. The predicted shifts in circumpolar storm tracks and pressure gradients have a significant effect on local wind resource availability, and impact the wind energy industry in a time of crucial expansion. This study uses Scotland as a case study to model the impact of the SRES A1B climate change scenario on current wind resource availability and wind power potential at two wind farms: Gordonbush (NE Scotland) and Dun Law (SE Scotland). The results predicted an increase of wind resource availability at Gordonbush, and a decrease at Dun Law, leading to corresponding changes in net annual electricity production: a 31.7% increase at Gordonbush and a 31.8% decrease at Dun Law by the year 2040. The majority of observed changes can be attributed to climate-forced changes in atmospheric circulation patterns; however, this research also shows the impact of turbine specifications and site characteristics on the vulnerability of wind power production to climate change. Further work is needed to establish a robust relationship between large-scale climate forcing and local wind resource availability, and to integrate this relationship into the assessment framework of on-shore wind farms around the world.

“…In Brazil, losses on the Tamandaré Beach (Pernambuco) have been related to the increasing frequency and intensity of storms in 2003, which increased the transport of sediments, acting on the distribution and biomass of H. wrightii . On the semiarid coast, the intertidal seagrass meadows are strongly influenced by rain and wind patterns, and, consequently, they may be drastically affected by the effects of climate change related to the diminishing of precipitation indexes (REBOUÇAS, 2004) and the doubling of the actual windy velocity (PEREIRA et al, 2013), expected by the end of this century.…”

Seagrass and Submerged Aquatic Vegetation (VAS) Habitats off the Coast of Brazil: state of knowledge, conservation and main threats

Financial Support: This study was supported by the Brazilian Network for Coastal Benthic Studies -ReBentos (Programa SISBIOTA), Rede CLIMA and INCT for Climate Changes; sponsored by CNPq and FAPESP. Seagrass meadows are among the most threatened ecosystems on earth, raising concerns about the equilibrium of coastal ecosystems and the sustainability of local fisheries. The present review evaluated the current status of the research on seagrasses and submerged aquatic vegetation (SAV) habitats off the coast of Brazil in terms of plant responses to environmental conditions, changes in distribution and abundance, and the possible role of climate change and variability. Despite an increase in the number of studies, the communication of the results is still relatively limited and is mainly addressed to a national or regional public; thus, South American seagrasses are rarely included or cited in global reviews and models. The scarcity of large-scale and long-term studies allowing the detection of changes in the structure, abundance and composition of seagrass habitats and associated species still hinders the investigation of such communities with respect to the potential effects of climate change. Seagrass meadows and SAV occur all along the Brazilian coast, with species distribution and abundance being strongly influenced by regional oceanography, coastal water masses, river runoff and coastal geomorphology. Based on these geomorphological, hydrological and ecological features, we characterised the distribution of seagrass habitats and abundances within the major coastal compartments. The current conservation AbstrActPradarias de gramas marinhas e vegetação aquática submersa (VAS) estão entre os ecossistemas mais ameaçados do planeta, gerando preocupação sobre o equilíbrio dos ecossistemas costeiros e a sustentabilidade das pescarias. A presente revisão avaliou o estado do conhecimento sobre as pradarias marinhas e VAS do Brasil, considerando as respostas das plantas às condições ambientais, e o possível papel da geomorfologia costeira e variabilidade climática sobre a distribuição e abundância das populações. Apesar do crescente aumento no número de publicações, a comunicação dos resultados ainda é relativamente limitada e destina-se principalmente ao público nacional ou regional. Como resultado, as pradarias de gramas marinhas da América do Sul raramente são incluídas ou citadas em revisões e modelos globais. A escassez de estudos em larga escala e de longo prazo, permitindo a detecção de mudanças na estrutura, abundância e composição dos habitats e espécies associadas, limita a investigação das comunidades no que diz respeito aos efeitos potenciais das mudanças climáticas. Pradarias marinhas e VAS ocorrem ao longo de toda a costa brasileira, mas a distribuição e abundância das espécies são influenciadas pela oceanografia regional, massas de água costeiras, descarga de rios e geomorfologia costeira. Com base nas características oceanográficas, geomorfológicas, hidrológicas e ecológicas, o estudo discutiu a distr...
