In 5 years the Amazon has experienced 2 extremely severe droughts. (Earth Week)Living on Earth: Amazon Forest as a Source of Carbon Dioxide: "In recent years there's been a distinct lack of rain in the Amazon rainforest. 'The drought of the century' is what they called the first in 2005, but the second, just 5 years later, was even worse. The forest is drying and the trees are dying, destroying the vast region's ability to absorb carbon from the atmosphere. University of Leeds researcher Oliver Phillips says instead of acting as a carbon sink, the Amazon forest is becoming a huge source of climate changing gases."
