Critical transitions in the Amazon forest system
The possibility that the Amazon forest system could soon reach a tipping point, inducing large-scale collapse, has raised global concern 1–3 . For 65 million years, Amazonian forests remained relatively resilient to climatic variability. Now, the region is increasingly exposed to unprecedented stress from warming temperatures, extreme droughts, deforestation and fires, even in central and remote parts of the system 1 . Long existing feedbacks bet…

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…
Climate change and disasters: Analysis of the Brazilian regional inequality
One of the main consequences of climate change in Brazil is the increase in the occurrence of extreme rainfall, which in turn trigger Hydrometeorological disasters; the Brazilian continental dimension, the regional characteristics of biomes and socioeconomic inequality are conditioning factors for the impacts of extreme events in the country. This work analyzes Brazil’s socioeconomic and urban infrastructure vulnerability, combined with the regio…
Impacts of extreme climate events on Brazilian agricultural production
Brazilian agricultural production stands out in world food security, accounting for a large part of the food produced worldwide. However, occurrence of extreme climate events is a challenge for the sector across the country. Thus, this study aims to assess extreme climate events impacts on Brazilian agricultural production. The loss index was calculated using crop data made available by the IBGE from 2005 to 2017, while data on the occurrence of …

Adaptation opportunities for water security in Brazil
We sought to identify priorities and adaptation opportunities for water security across the various Brazilian biomes. With ever-growing demand and water-usage, future climate scenarios suggest that further water resources management constraints are to be endured throughout the next two decades. The unbalance between high-quality water demand and availability in a multisectoral usage context (e.g., domestic, industry, agribusiness) highlights the …
Size does matter: City scale and the asymmetries of climate change adaptation in three coastal towns
Globally, it is smaller urban settlements that are growing most rapidly, are most constrained in terms of adaptive capacity but increasingly looked to for delivering local urban resilience. Data from three smaller coastal cities and their wider regional governance systems in Florida, US; West Sussex, UK and São Paulo, Brazil are used to compare the influence of scale and sector on city adaptive capacity. These tensions are described through the l…

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…
The influence of oceanic basins on drought and ecosystem dynamics in Northeast Brazil
The 2012 drought in Northeast Brazil was the harshest in decades, with potentially significant impacts on the vegetation of the unique semi-arid caatinga biome and on local livelihoods. Here, we use a coupled climate–vegetation model (CCM3-IBIS) to: (1) investigate the role of the Pacific and Atlantic oceans in the 2012 drought, and; (2) evaluate the response of the caatinga vegetation to the 2012 climate extreme. Our results indicate that anomal…
The extreme 2014 flood in south-western Amazon basin: The role of tropical-subtropical South Atlantic SST gradient
Unprecedented wet conditions are reported in the 2014 summer (December-March) in Southwestern Amazon, with rainfall about 100% above normal. Discharge in the Madeira River (the main southern Amazon tributary) has been 74% higher than normal (58 000 m 3 s -1 ) at Porto Velho and 380% (25 000 m 3 s -1 ) at Rurrenabaque, at the exit of the Andes in summer, while levels of the Rio Negro at Manaus were 29.47 m in June 2014, corresponding to the fifth …

Present-day South American climate
Causes and impacts of the 2005 Amazon drought
A rare drought in the Amazon culminated in 2005, leading to near record-low streamflows, small Amazon river plume, and greatly enhanced fire frequency. This episode was caused by the combination of 2002–03 El Niño and a dry spell in 2005 attributable to a warm subtropical North Atlantic Ocean. Analysis for 1979–2005 reveals that the Atlantic influence is comparable to the better-known Pacific linkage. While the Pacific influence is typically lock…
The influence of changes in orbital parameters over South American climate using the CPTEC AGCM: Simulation of climate during the mid Holocene
Climate change has been analysed for the mid Holocene (MH, 6000 years BP) over South America. Simulations have been performed through modification of the orbital parameters and the CO 2 concentration typical of the MH within the CPTEC T062L28 atmospheric general circulation models (AGCM). The results were compared with previous simulations performed by various climate centres around the world and with palaeoclimate indicators. The MH climate simu…
