- Explain how Amazon rainforest transpiration releases water vapour that contributes to rainfall and regional cooling, so forest loss weakens these feedbacks.
IB Biology HL D4.2.3 Amazon Rainforest Deforestation Questions question 1
Satellite imagery has been used for many years in the Amazon rainforest to monitor deforestation. Annual deforestation can be calculated using data from several satellites that have varying levels of accuracy. The graph shows the area of the Amazon rainforest that was deforested each year from 2001 to 2019, calculated using satellite images.
The Amazon rainforest currently releases very large amounts of water vapour into the atmosphere through transpiration. Suggest one consequence of this.
