Resulting changes in evapo-transpiration and therefore convective precipitation could further accelerate drought conditions and destabilize the tropical ecosystem as a whole, causing a reduction in its biomass carrying capacity or dieback. In turn, changes in the structure of the Amazon and its associated water cycle will have implications for the many endemic species it contains and result in changes at a continental scale.
At the global level, it is very alarming that the Amazon forest may soon become a net emitter of carbon dioxide, rather than a potential carbon sink, contributing to climate change and further reducing the resilience of communities and ecosystems. The results of the review show how the extent of forest-based livelihoods is often under-appreciated. New Mammal Discovered in Cloud Forest. The process becomes a self-reinforcing feedback loop.

Clearly, with much at stake, if climate-induced damage alters the state of the Amazon ecosystem, there is a need to better understand its risk, process, and dynamics. The objective of this study is to assist in understanding the risk, process, and dynamics of potential Amazon dieback and its implications.

The Amazonian south and southeast will receive much less rainfall. The process becomes a self-reinforcing feedback loop. At the 15th Conference of Parties to the U.
Framework Convention on Climate Change, held in Copenhagen in December, virtually all countries agreed that the warming must not surpass two degrees. It is estimated that a single hectare of Amazon rainforest contains about tonnes of living plants, including more than types of trees and 1, other plants, the report notes. For example, one in five of all birds in the world can be found there.
Sadly, before the end of this century many, and perhaps most, of those species will become extinct. After millions of years of existence many plants, insects, birds, animals will never be seen again on the Earth.
Habitat loss and climate change will be the biggest reasons for their extinction. The Intergovernmental Panel on Climate Change conservatively estimates that 30 percent of all species will be extinct by the end of this century, if global warming is not kept below two degrees.
