13. “Infrastructural geopolitics” of climate knowledge: the Brazilian Earth System Model and the North-South knowledge divide
Resumo Este artigo examina como a geopolítica se insere nos esforços das nações do Sul de construção de novas infraestruturas de conhecimento climático. Para tanto, analisa-se a composição da base internacional de modelagem climática do Painel Intergovernamental sobre Mudanças Climáticas (IPCC), sob a perspectiva do Modelo Brasileiro do Sistema T

14. Disarray in global governance and climate change chaos
Resumo Os cientistas alertam para o fato de que a atividade humana no Antropoceno está provocando a transgressão de vários limites planetários. A equação população, meio ambiente e desenvolvimento ficou insolúvel. Este artigo revisa a trajetória das mudanças climáticas, discute as limitações dos esforços atuais para lidar com elas e analisa a

15. Global warming decreases the morphological traits of germination and environmental suitability of Dipteryx alata (Fabaceae) in Brazilian Cerrado
ABSTRACT We experimentally evaluated how different temperatures affect germination of individual seedlings of Dipteryx alata, and estimated the impact of climate change on the species using ecological niche modeling. A total of 240 seeds were randomly distributed among three different temperature treatments (32 ºC, 36 ºC, and 40 ºC), and monitored for 35

16. Identifying agriculture land acquisitions for alleviating future food security concerns
Abstract The total available land for food, fuel, or forests is finite, while land demand is increasing and expected to increase further in the coming decades; resulting in deterioration of food security. Therefore, the corporate world adopted a solution of acquiring international agricultural land. Consequently, the global demand for land has progressively

17. Impacts of land-use change on southeast Amazonia basin streamflow
Resumo A Região Amazônica vem despertando interesse crescente da comunidade científica internacional devido às amplas possibilidades ambientais que suas densas florestas têm a oferecer no que diz respeito à regulação climática e recursos hídricos. Apesar dos muitos esforços de agências reguladoras de meio ambiente e centros de pesquisa, esta regi

18. A snapshot of the limnological features in tropical floodplain lakes: the relative influence of climate and land use
Resumo Objetivo O objetivo desse estudo foi investigar a influência relativa do clima (temperatura e precipitação) e do uso da terra nas características limnológicas de 30 lagoas da planície de inundação do Rio Araguaia, no Brasil Central, um importante rio que drena no Cerrado brasileiro. Métodos As lagoas foram amostradas em um mesmo período,

19. Climatic variables associated with dengue incidence in a city of the Western Brazilian Amazon region
Abstract INTRODUCTION: This study aimed to examine the impact of climate variability on the incidence of dengue fever in the city of Rio Branco, Brazil. METHODS: The association between the monthly incidence of dengue fever and climate variables such as precipitation, temperature, humidity, and the Acre River level was evaluated, using generalized autore

20. Using climate change models to assess the probability of weather extremes events: a local scale study based on the generalized extreme value distribution
ABSTRACT Regional climate models (e.g. Eta) nested to global climate models (e.g. HadGEM2-ES and MIROC5) have been used to assess potential impacts of climate change at regional scales. This study used the generalized extreme value distribution (GEV) to evaluate the ability of two nested models (Eta-HadGEM2-ES and Eta-MIROC5) to assess the probability of dai

21. Santarém: o ponto de partida para o (ou de retorno) urbano utopia
Resumo Este artigo discute o progressivo descolamento observado entre cidade, urbano, rural e natureza em contexto amazônico. Partiu-se da geo-história, abordagem lefebvriana de análise da formação espacial, do sítio de Santarém (PA) e adjacências, para explicitar a natureza híbrida de um tecido urbano extensivo, formado por tipologias urbanas desc

22. Anticipating the response of the Brazilian giant earthworm (Rhinodrilus alatus) to climate change: implications for its traditional use
Abstract Our understanding of the impacts of ongoing global warming on terrestrial species has increased significantly during the last several years, but how climatic change has affected, and will affect, the distribution of earthworms remains largely unknown. We used climate niche modeling to model the current distribution of the giant earthworm Rhinodrilus

23. Soil CO2 Efflux Measurements by Alkali Absorption and Infrared Gas Analyzer in the Brazilian Semiarid Region
ABSTRACT The CO2 emission from the soil surface, commonly referred to as soil CO2 efflux (ECO2) or soil respiration, is the sum of processes that include root respiration and microbial activity. Measuring this evolution is important to establish sustainable land use models and to estimate global fluxes of carbon, which affect climate change. Despite its impo

24. Assessing the risk zones of Chagas' disease in Chile, in a world marked by global climatic change
BACKGROUND Vector transmission of Trypanosoma cruzi appears to be interrupted in Chile; however, data show increasing incidence of Chagas' disease, raising concerns that there may be a reemerging problem. OBJECTIVE To estimate the actual risk in a changing world it is necessary to consider the historical vector distribution and correlate this distribution
