Consórcios públicos intermunicipais de resíduos sólidos em regiões metropolitanas no Brasil
O trabalho tem o objetivo de mostrar fatores contextuais, a partir da Instititutional Collective Action (ICA), que influenciam a cooperação intermunicipal dos consórcios públicos intremunicipais de tratamento de resíduos nas Regiões Metropolitanas no Brasil. Os consórcios públicos intermunicipais na área de resíduos sólidos são importantes para a Política Nacional de Resíduos Sólidos (lei 12.305/2010). Com a agregação intermunicipal é possível a …
Future rainfall and temperature changes in Brazil under global warming levels of 1.5oC, 2oC and 4oC
The present study analyzes the impacts of global warming of 1.5oC, 2oC, and 4oC above pre-industrial levels in the Brazilian territory. Climate change projected among the different global warming levels has been analyzed for rainfall, temperature and extreme climate indices. The projections are derived from the global climate model HadGEM3-A, from the High-End cLimate Impacts and eXtremes (HELIX) international project, from the United Kingdom, fo…
Simulation of the Holocene climate over South America and impacts on the vegetation
We provide a comprehensive analysis of the Holocene climate and vegetation changes over South America through numerical simulations. Holocene climate for several periods (8 ka, 6 ka, 4 ka, 2 ka, and present) were simulated by an atmospheric general circulation model, forced with orbital parameters, CO 2 concentrations, and sea surface temperature (SST), while the analysis of the biome distributions was made with a potential vegetation model (PVM)…
Land-use and climate change risks in the Amazon and the need of a novel sustainable development paradigm
Significance The Amazonian tropical forests have been disappearing at a fast rate in the last 50 y due to deforestation to open areas for agriculture, posing high risks of irreversible changes to biodiversity and ecosystems. Climate change poses additional risks to the stability of the forests. Studies suggest “tipping points” not to be transgressed: 4° C of global warming or 40% of total deforested area. The regional development debate has focus…
A seca e a crise hídrica de 2014-2015 em São Paulo
During most of the rainy season in 2014, the Southeast of Brazil - including the Cantareira reservoir system - received below-normal rainfall. The main cause leading to that heavy lack of rain was an intense, persistent and anomalous highpressure system blocking moisture flow from the Amazon and the development and passage of cold front systems and the South Atlantic Convergence Zone, which are responsible for rainfall in this region during summe…
Evolução dos Modelos Climáticos e de Previsão de Tempo e Clima
A atmosfera da Terra é geralmente considerada como um exemplo de sistema caótico onde as flutuações atmosféricas em escalas de tempo superiores a cerca de duas semanas são imprevisíveis. No entanto, apesar dessa limitação, é possível fazer previsões com antecedência de meses. Como são feitas as previsões de tempo e clima? Como evoluiu a modelagem atmosférica até o presente e quais são as limitações? Seria possível prever como será o próximo inver…
On the associations between Hydrometeorological conditions in Amazonia and the extremes of the Southern Oscillation
Association entre les conditions hydrométéorologiques en Amazonie et les extrêmes de l’oscillation du sud L’Amazonie du nord et du centre montre une tendance vers une anomalie négative de la pluviométrie de l’été au cours des phases avancées d’événements El Niño forts comme ceux de 1982/83, 1986/87 et de 1997/98. Cependant on observe aussi une tendance vers une anomalie positive de la pluviométrie, certaines années El Niño comme 1972/73. Une inve…
