Deforestation accounts for 18-20% of global carbon emissions and the Amazon rainforest is close to a tipping point of 20% deforestation that could drastically impact the ecosystem. Currently, 17-18% of the Amazon has already been lost, bringing the remaining rainforest close to the 20% threshold that some scientists have warned would be a point of no return. Trees play a vital role in absorbing carbon dioxide from the atmosphere and producing oxygen.

- % of Co2 emissions 2% to 50 %
- based on a report by the World Bank entitled, Assessment of the Risk of Amazon Dieback. At this point deforestation combined with spreading fires and overall warming of 2 degrees Celsius would cause parts of the Amazon's hydrogeologic system to break down.
- However, other studies have found that 'die-off' point for the Amazon rainforest would occur only after 40-60 percent of the forest was lost. The differences in such findings displays the complicated nature of climate science, however the studies all agree that the Amazon faces unparalleled pressures that if unchecked will result in massive forest loss
