Localized ecological systems are known to shift abruptly and irreversibly from one state to another when they are forced across critical thresholds. Here we review evidence that the global ecosystem as a whole can react in the same way and is approaching a planetary-scale critical transition as a result of human influence. The plausibility of a planetary-scale ‘tipping point’ highlights the need to improve biological forecasting by detecting early warning signs of critical transitions on global…

Early warning signals in complex ecosystems

Abstract. Given the potential for elements of the Earth system to undergo rapid, hard to reverse changes in state, there is a pressing need to establish robust methods to produce early warning

A Natural Resource-Systems approach: Targeting the Ecological Transition at the Regional Scale

Human history can be mirrored in a geo-history of natural resources. Humans, by over-exploiting resources (“forcing”), have produced extensive land use changes and have altered complex food webs,

Cascading Transitions in Coupled Complex Ecosystems

This paper examines the role of biological feedback on planetaryscale transitions and presents a conceptual model in which stability emerges as a consequence of interactions between environment and life.

Preparing for a Fast-forward Future in the Sacramento-San Joaquin Delta

California’s Sacramento-San Joaquin Delta has undergone a profound transformation since the Gold Rush of the nineteenth century (Whipple et al. 2012). Now, as the effects of climate change gain

Bioengineering the biosphere

Multiple drivers and extreme events collapse social-ecological systems sooner

The world’s ecosystems are undergoing unprecedented changes due to the impact of climate change and local human activities. A major concern is the possibility of tipping points where ecosystems and

Our future in the Anthropocene biosphere

This article provides a systemic overview of the current situation where people and nature are dynamically intertwined and embedded in the biosphere, placing shocks and extreme events as part of this dynamic.

It is suggested that the Millennium Development Goals need to be reframed in such a planetary stewardship context combined with a call for a new social contract on global sustainability.

Trophic Downgrading of Planet Earth

This empirical work supports long-standing theory about the role of top-down forcing in ecosystems but also highlights the unanticipated impacts of trophic cascades on processes as diverse as the dynamics of disease, wildfire, carbon sequestration, invasive species, and biogeochemical cycles.

Regime shifts in ecological systems can occur with no warning.

It is shown that the class of ecological systems that will exhibit leading indicators of regime shifts is limited, and that there is a set of ecological models and, therefore, also likely to be a class of natural systems for which there will be no forewarning of a regime change.

Early Warnings of Regime Shifts: A Whole-Ecosystem Experiment

High-frequency monitoring of manipulated and reference lakes enabled early detection of subsequent catastrophic regime shift in an aquatic food web, corroborating theory for leading indicators of ecological regime shifts.

The Anthropocene is a reminder that the Holocene, during which complex human societies have developed, has been a stable, accommodating environment and is the only state of the Earth System that the authors know for sure can support contemporary society.

Work in different scientific fields is now suggesting the existence of generic early-warning signals that may indicate for a wide class of systems if a critical threshold is approaching.

Differences between fossil and modern data and the addition of recently available palaeontological information influence understanding of the current extinction crisis, and results confirm that current extinction rates are higher than would be expected from the fossil record.

This work introduces a framework that uses information from different sources to identify vulnerability and to support the design of conservation responses, and reviews the insights that different approaches bring to anticipating and managing the biodiversity consequences of climate change.
