Starting in roughly the year 2000, formal research projects (using molecular data, [2] microfossil botanical techniques, [2] remote sensing, [1] and plant genetics [3]) have resurrected the story of human settlement of the Amazon Basin [2] – the Basin is no longer thought to have been a primeval forest at the time of European contact and can ...

The hydrogen/carbon percentage [35] or molecular markers such as benzenepolycarboxylic acid, [36] are used as a second level of identification. [7] Indigenous people added low temperature charcoal to poor soils. Up to 9% black carbon has been measured in some terra preta (against 0.5% in surrounding soils). [37]
The Amazon basin is the part of South America drained by the Amazon River and its tributaries. The Amazon drainage basin covers an area of about 7,000,000 km 2 (2,700,000 sq mi), [ 1 ] or about 35.5 percent of the South American continent.
The Amazon contains about 10% of the world’s land-based biodiversity and stores incredible amounts of carbon in its dense trees. The rainforest is a carbon sink, meaning it stores more carbon ...
The Omagua people (also known as the Umana, Cambeba, and Kambeba) are an indigenous people in Brazil's Amazon Basin. Their territory, when first in contact with Spanish explorers in the 16th century, was on the Amazon River upstream from the present-day city of Manaus extending into Peru. They speak the Omagua language.
Ocean mixed layer carbon, c m, is the only explicitly modelled ocean stock of carbon; though to estimate carbon cycle feedbacks the total ocean carbon is also calculated. [ 107 ] Current trends in climate change lead to higher ocean temperatures and acidity , thus modifying marine ecosystems. [ 108 ]
The blue numbers indicate how much carbon moves between reservoirs each year. The actual image filename is a bit dodgy, but the diagram itself is clear, useful and attractive. The fullsize framed version (so that the text is legible) illustrates carbon cycle. It originally came from a NASA publication. - Solipsist 21:37, 4 Apr 2005 (UTC)
