Climate News Network: The continued destruction of the Amazon to exploit its resources for mining, agriculture and hydro-power is threatening the future of the South American continent, according to a report by campaigning groups using the latest scientific data. Five countries--Bolivia, Brazil, Colombia, Ecuador and Peru--share the Amazon, and for all of them the forest area occupies more than 40 percent of their territory. All face threats to their water supply, energy production, food and health. In addition,...

Mongabay: The 28 percent increase in deforestation in the Brazilian Amazon over last year that was reported this week is bad news, but it is not surprising. It is bad news because the decline in deforestation since 2005 has given us the single largest contribution to climate change mitigation on the planet, far surpassing the reductions in emissions achieved by any Annex 1 country under the Kyoto Protocol [1]. Brazils achievement is particularly noteworthy because it did not come at the expense of agricultural...

The study is based on high resolution computer modeling that stripped the Amazon of its forest cover and assessed the potential impact on wind and precipitation patterns. While the scenario is implausible, it reveals the global nature of the ecological services afforded...

Mongabay: Data released by the Brazilian government Friday confirms an increase in Amazon forest loss. Brazil's National Space Research Institute, INPE, updated data from its near-real-time deforestation tracking system, known as DETER. The system showed a near five-fold increase in forest loss during May 2013 relative to a year earlier, from 99 square kilometers to 465 sq km. 59 percent of the clearing occurred in Mato Grosso, a state in the Southern Amazon where large-scale farms and cattle ranching drive...
