Arctic sea ice: decadal simulations and future scenarios using BESM-OA
Important international reports and a significant number of scientific publications have reported on the abrupt decline of Arctic sea ice and its impact on the Global Climate System. In this paper, we evaluated the ability of the newly implemented Brazilian Earth System Model (BESM-OA) to represent ...- por Portal Padrão

Forestry expansion during the last decades in the Paraiba do Sul basin – Brazil
In this work, we analyze the expansion of forestry activities with Eucalyptus in the Paraiba do Sul basin, region located in Sao Paulo, Brazil, from 1986 to 2010. In this region is situated the most important and largest extension of reminiscent of Mata Atlântica Biome reminiscent. This biome has b...- por Portal Padrão

Mineração de trajetórias de mudança de cobertura da terra em estudos de degradação florestal
A cobertura da terra encontra-se em constante transformação devido aos diferentes fatores que influenciam a sua utilização e destinação. Essas alterações observadas ao longo do tempo definem o que chamamos de Trajetórias de Mudança de Cobertura da Terra. Tais trajetórias, uma vez caracter...- por Portal Padrão

State of the climate in 2015
In 2015, the dominant greenhouse gases released into Earths atmospherecarbon dioxide, methane, and nitrous oxideall continued to reach new high levels. At Mauna Loa, Hawaii, the annual CO2 concentration increased by a record 3.1 ppm, exceeding 400 ppm for the first time on record. The 2015 global CO...- por Portal Padrão

Upward lightning flashes characteristics from high-speed videos
One hundred high-speed video recordings (72 cases in Brazil and 28 cases in USA) of negative upward lightning flashes were analyzed. All upward flashes were triggered by another discharge, most of them positive CG flashes. A negative leader passing over the tower(s) was frequently seen in the high-s...- por Portal Padrão

Evolution and challenges of dynamic global vegetation models for some aspects of plant physiology and elevated atmospheric CO2
Dynamic global vegetation models (DGVMs) simulate surface processes such as the transfer of energy, water, CO2, and momentum between the terrestrial surface and the atmosphere, biogeochemical cycles, carbon assimilation by vegetation, phenology, and land use change in scenarios of varying atmospheri...- por Portal Padrão

Forest degradation associated with logging frontier expansion in the Amazon: the BR-163 region in southwestern Pará, Brazil.
Forest degradation is the long-term and gradual reduction of canopy cover due to forest fire and unsustainable logging. A critical consequence of this process is increased atmospheric carbon emissions. Although this issue is gaining attention, forest degradation in the Brazilian Amazon has not yet b...- por Portal Padrão

An assessment of urban vulnerability in the Amazon Delta and Estuary: a multi-criterion index of flood exposure, socio-economic conditions and infrastructure
The Amazon Delta and Estuary (ADE) is a region of continental and global ecological importance. Controversy, many of the basic infrastructure and services essential for quality of life and sustainable development of this delta are absent. Using a conceptual model to define socio-economic vulnerabili...- por Portal Padrão
