INPE reduces share of the Amazon deforestation on the greenhouse

The Brazilian Amazon deforestation contributes approximately 2.5% of global emissions of greenhouse gases (GHGs), global warming, according to a preliminary calculation made by scientists from the National Institute for Space Research (INPE). The carbon footprint is huge. However, proportionately smaller than previously thought, according to the director of INPE, Gilberto Cāmara. The initial estimate, he says, was that deforestation in the Brazilian Amazon accounted for 5% of global emissions of GHGs (mainly carbon dioxide and carbon dioxide - CO2). The new calculation was made at a meeting with scientists from the Institute on Friday, after a consultation report by the newspaper O Estado de S. Paulo.
Board emphasizes that it is a preliminary estimate, which still needs to be refined - but that should not divert much of that magnitude. The account was based on the rate of deforestation in 2008, which was approximately 13 square kilometers. The director of the space agency would like to know that another estimate has been widely quoted in international discussions, that the accumulated deforestation in the world produces 20% of global emissions of GHGs. This number, he said, is based on data overestimated the Foundation of the United Nations Food and Agriculture Organization (FAO), which adopts the average for Brazil an annual deforestation of 30 square miles - far above the real.
In the past 20 years, according to the space agency's own data, the average annual deforestation in the Brazilian Amazon was approximately 18 square kilometers. "There is no reliable scientific basis for these 20%," said Cāmara. He says he believes a more realistic estimate is around 10%, according to a study published by the World Resources Institute.
IPCC
The calculation of 20% is cited in the reports of the Intergovernmental Panel on Climate Change (IPCC) and has served as a basis for international negotiations about the contribution of deforestation (and developing countries) to global warming. The new numbers, according to Cāmara, not in any way diminish the need to stem deforestation. But fall, yes, what effect this may have on climate change on a global scale.
