Existing hydroelectric dams in Brazilian Amazonia emitted about 0.26 million tons of methane and 38 million tons of carbon dioxide in 1990. The methane emissions represent an essentially permanent addition to gas fluxes from the region, rather than a one-time release. The total area of reservoirs planned in the region is about 20 times the area existing in 1990, implying a potential annual methane release of about 5.2 million tons. About 40% of this estimated release is from underwater decay of… 
Do Hydroelectric Dams Mitigate Global Warming? The Case of Brazil's CuruÁ-una Dam
Hydroelectric dams in tropical forest areas emit greenhouse gases, as illustrated by the Curuá-Una Dam in the Amazonian portion of Brazil. Emissions include carbon dioxide from decay of the
Greenhouse gas emissions from Brazil’s Amazonian hydroelectric dams
Tropical dams are often falsely portrayed as ‘clean’ emissions-free energy sources. The letter by de Faria et al (2015 Environ. Res. Lett. 10 124019) adds to evidence questioning this myth.
Are hydroelectric dams in the Brazilian Amazon significant sources of ‘greenhouse’ gases?
Possible implications of climate change have motivated a series of studies on the greenhouse gas (GHG) emissions from hydroelectric dams (Oud 1993; Rudd et ah 1993). Some of these studies have
Greenhouse Gas Emissions From Hydroelectric Dams in Tropical Forests
Hydroelectric dams are not necessarily sources of “clean energy” because they produce greenhouse emissions that can be substantial. Carbon dioxide (CO2) is emitted by above-water decay of trees left
Gaseous emissions and oxygen consumption in hydroelectric dams: A case study in French Guyana
Methane, carbon dioxide, and hydrogen sulfide emissions from the hydroelectric dam of Petit Saut on the Sinnamary River in French Guyana have been measured over a 2 year period. Since the beginning
Emissions of greenhouse gases from the tropical hydroelectric reservoir of Petit Saut (French Guiana) compared with emissions from thermal alternatives
Greenhouse gas (GHG) emissions of CH4 and CO2, resulting from decomposition of flooded organic matter from the hydroelectric reservoir of Petit Saut in the tropical rain forest of French Guiana have
Greenhouse Gas Emissions from a Hydroelectric Reservoir (Brazil’s Tucuruí Dam) and the Energy Policy Implications
Greenhouse gas emissions from hydroelectric dams are oftenportrayed as nonexistent by the hydropower industry, and havebeen largely ignored in global calculations of emissions fromland-use change.

Long‐term greenhouse gas emissions from hydroelectric reservoirs in tropical forest regions
The objective of this work is to quantify long‐term emissions of two major greenhouse gases, CO2 and CH4, produced by the decomposition of the flooded organic matter in tropical artificial
Methane stocks in tropical hydropower reservoirs as a potential energy source
Several studies over the last decade have shown that tropical reservoirs may constitute an appreciable source of methane (CH4) to the atmosphere. Here, we show that the use of low-cost, innovative


Methane flux from the Amazon River floodplain: Emissions during rising water
During April and May of 1987, an extensive methane flux data set from Amazonian wetland habitats was collected during the wet season as river water levels were high and rising. This work extends
Brazil's Balbina Dam: Environment versus the legacy of the Pharaohs in Amazonia
The Balbina Dam in Brazil's state of Amazonas floods 2360 km2 of tropical forest to generate an average of only 112.2 MW of electricity. The flat topography and small size of the drainage basin make
Seasonal dynamics in methane emissions from the Amazon River floodplain to the troposphere
Methane fluxes to the troposphere from the three principal habitats of the floodplain of the Amazon River main stem (open waters, emergent macrophyte beds, and flooded forests) were determined along
Rainforest burning and the global carbon budget: Biomass, combustion efficiency, and charcoal formation in the Brazilian Amazon
Biomass present before and after burning was measured in forest cleared for pasture in a cattle ranch (Fazenda Dimona) near Manaus, Amazonas, Brazil. Aboveground dry weight biomass loading averaged
Biomass and Structure in a Central Amazonian Rain Forest
Klinge and Rodrigues (1971) analyzed the structure and floristic composition of a central Amazonian rain forest stand northeast of Manaus, state of Amazonas, Brazil. The 0.2-ha study site was on
Exchange of Materials Between Terrestrial Ecosystems and the Atmosphere
Focused studies of the interactions between the atmosphere and the biosphere that regulate trace gases can improve both the understanding of terrestrial ecosystems and the ability to predict regional- and global-scale canges in atmospheric chemistry.
Radiative forcing of climate
An update of the scientific discussions presented in Chapter 2 of the Intergovernmental Panel on Climate Change (IPCC) report is presented. The update discusses the atmospheric radiative and chemical
