Global tipping points

Anson Mackay co-authors critique

Global tipping points

Trends in Ecology & Evolution has published three articles in a Focus Issue on global tipping points. Two Opinion articles set out the opposing arguments for and against, while a Forum article provides an introduction and overview.

Dr Anson Mackay is a co-author of one of the opinion articles which asks: Does the terrestrial biosphere have planetary tipping points?

While at local and regional scales human action may cause radical  and potentially irreversible system shifts, the likelihood of planetary scale tipping points in the terrestrial biosphere remains unconfirmed.

Evaluation of potential mechanisms and drivers, including their spatial heterogeneity and responses, and lack of strong continental interconnectivity, suggest that changes at the global scale are likely to be relatively smooth, without marked tipping patterns.
