Ecological collapse is likely to start sooner than previously believed with tipping points amplifying and accelerating one another. In some systems, adding new extreme events on top of other ongoing stresses could bring the timing of a predicted tipping point closer to the present by as much as 80%. More than a fifth of ecosystems worldwide, including the Amazon rainforest, are at risk of a catastrophic breakdown within a human lifetime. The Intergovernmental Panel on Climate Change said there was a chance of a tipping point in the Amazon by the year 2100. Unfortunately, a breakdown may occur several decades earlier than it predicted.
