Ecological tipping points could occur much sooner than expected, study finds
(www.theguardian.com)
tl;dr:
Ecological collapse is likely to start sooner than previously believed, according to a new study that models how tipping points can amplify and accelerate one another. Compared with the long-established and conclusively proven link between fossil fuels and global heating, the science of tipping points and their interactions is relatively undeveloped. Several prominent Brazil-based scientists, including Carlos Nobre, have warned that this may come much sooner. Lake Erhai in China collapsed sooner than most observers expected. While the scope of the study was limited, the authors said the results showed the need for policymakers to act with more urgency.
