“…Costa et al (2010) encontraram diferenças significativas de temperatura entre áreas cobertas por vegetação e pavimentação na área urbana de Ilha Solteira, no estado de São Paulo (SP). Também em SP, Lima et al (2013) investigaram a variação da temperatura do ar em áreas de mangue impactadas e conservadas. Os autores encontraram maior amplitude térmica, com máxima mais alta, nas áreas de mangue não conservadas.…”

Resumo As ondas de calor impactam setores socioeconômicos em diversas regiões do mundo. Dentro deste tema, o efeito do calor à saúde pública é um dos mais estudados, especialmente no que tange ao aumento da taxa de mortalidade humana. Procurando dar subsídios para possíveis ações mitigadoras no Brasil, o presente estudo propõe apresentar as características de frequência, duração, abrangência espacial e intensidade das ondas de calor. Utilizou-se dados de temperatura máxima diária (Tmax) da série histórica (1961-2014) de 265 estações meteorológicas do Instituto Nacional de Meteorologia (INMET), separadas em três áreas do Brasil. Primeiramente, selecionou-se os eventos que, durante três ou mais dias, pelo menos a metade das observações na área apresentaram Tmax superando a média de Tmax mais um desvio padrão. Posteriormente, a média espacial e temporal da Tmax foi definida como intensidade, Int. Por fim, os eventos com valores superiores ao terceiro quartil de Int foram definidos como ondas de calor. Foram encontradas 11 ondas de calor na área 1, 23 na área 2 e 31 na área 3, a maioria na primavera e/ou verão. Nosso principal achado mostra que o número de ondas de calor tem aumentado ao longo das últimas cinco décadas, sendo a maioria das ocorrências concentradas após os anos 2000, na atual fase fria da Oscilação Decadal do Pacífico (ODP). Também nesse período, foram verificadas as ondas de calor mais duradouras e intensas. As conclusões deste trabalho sobre frequência, duração e intensidade das ondas de calor aparecem como forte indicativo de que as mudanças climáticas globais têm influenciado o campo de temperatura no Brasil.

“…Thus, microclimate is regulated by the impacts of shade and insulation on local humidity and temperature extremes (Hudspeth 2005). Furthermore, the mangrove canopy influences the microclimate within the forest by providing a protected and shaded region where the RH is elevated, wind is negligible and sunlight is restricted (Mazda et al 2007;Lima et al 2013). There has been a substantial increase in RH in the study area from 1951 to 2010 (see Figure 5).…”

“…Several authors have reported that mangrove environments are influenced by atmospheric parameters such as air temperature, rain, humidity, wind, etc. (Lima et al 2013). For this purpose, 60 years of meteorological information were acquired and statistically analysed to sketch the climate portfolio of the study area.…”

The lack of comprehensive information on the climate of the coastal region results in insufficient understanding of the impact of changing climate on the coastal ecosystems and also impedes in framing suitable climate-based adaptation strategies and policies at the regional and local level. Monitoring current climate change demands a historical perspective, as much as possible, and framing a baseline climate data is important for establishing a reference point to assess climate change. Thus, the study of past climate change relies critically on the availability of datasets that characterize the climate of the region. In this context, the objective of this article is to provide climate portfolio (collection of climate information) of Pichavaram mangrove region of Tamil Nadu coast, India, and to give an outline of its predicted impacts. Climate data of the past 60 years have been collected, and the trend analysis of major climatic variables such as temperature, rainfall, relative humidity and wind speed has been studied statistically. This research article critically appraises the available climate data, identifies general patterns of climate change in the coastal region and highlights the gaps in existing knowledge on the impact of climate change at the local level. It gives a holistic approach on understanding climate at local level and provides baseline climate information. This, in turn, is expected to shore up in framing suitable adaptation strategies and policies for the coastal region with the most valuable ecosystem such as mangroves.

“…Mangrove microclimates have been studied to indicate what changes occur in the mangrove structure, at its edge, and within its ecosystem. In addition, the study of the microclimatic variables can contribute to the understanding of the importance of mangroves in the event of storms and extreme events at a local scale (LIMA et al, 2013;.…”

Mangrove forests provide essential ecosystem services to human communities, including climate regulation. In Brazil, the National System of Nature Conservation Units divides Protected Areas (PAs) into two categories: Full Protection (FP) and Sustainable Use (SU). The FP areas are composed of five categories, including National Parks, and the SU areas comprise seven categories, such as Environmental Protection Areas. The current research compared climatic attributes, leaf area index, and vegetation structure development in mangrove forests in two distinct categories of PAs (FP and SU) along the southern coast of the state of São Paulo (Brazil) to analyze the climatic conditions in different PA categories. A survey of the microclimatic attributes found that the conserved mangroves in the FP PA presented a) greater thermal stability in terms of the maximum, minimum, and mean air temperatures, and b) a better role of mangrove vegetation in (re)distributing the energy inside the forest. Therefore, it is affirmed that FP PAs play a fundamental role in maintaining the good conservation status of mangroves and, consequently, stabilizing the microclimate.
