Multi‐Stability of the Present‐Day Atlantic Meridional Overturning Circulation
The Atlantic Meridional Overturning Circulation (AMOC) plays a key role in the climate system, especially in the global meridional heat transport. Historical reconstructions indicate that the AMOC has weakened by about 15% since the mid‐20th century. Paleoclimate records, ocean theory, as well as a hierarchy of climate models suggest that the AMOC is a tipping element, sensitive to changes in buoyancy fluxes at the air‐sea interface, and could tr…
Multiple modes in tropical tree cover
Observations have been debated as portraying a multimodal distribution of tropical tree cover, even in regions with identical mean annual precipitation (MAP). Previous studies have discussed whether such multimodality is evidence of alternative stable states, which would indicate that tropical forests may irreversibly transition to a savanna-like state when deforestation and climate forcing reach a tipping point. However, doubts have been raised …
Critical transitions in the Amazon forest system
The possibility that the Amazon forest system could soon reach a tipping point, inducing large-scale collapse, has raised global concern 1–3 . For 65 million years, Amazonian forests remained relatively resilient to climatic variability. Now, the region is increasingly exposed to unprecedented stress from warming temperatures, extreme droughts, deforestation and fires, even in central and remote parts of the system 1 . Long existing feedbacks bet…
Arctic summer sea ice loss will accelerate in coming decades
The Arctic sea ice (ASI) is expected to decrease with further global warming. However, considerable uncertainty remains regarding the temperature range that would lead to a completely ice-free Arctic. Here, we combine satellite data and a large suite of models from the latest phase of the Coupled Model Intercomparison Project (CMIP6) to develop an empirical, observation-based projection of the September ASI area for increasing global mean surface…
Measuring tropical rainforest resilience under non-Gaussian disturbances
The Amazon rainforest is considered one of the Earth’s tipping elements and may lose stability under ongoing climate change. Recently a decrease in tropical rainforest resilience has been identified globally from remotely sensed vegetation data. However, the underlying theory assumes a Gaussian distribution of forest disturbances, which is different from most observed forest stressors such as fires, deforestation, or windthrow. Those stressors of…
Theoretical and paleoclimatic evidence for abrupt transitions in the Earth system
Specific components of the Earth system may abruptly change their state in response to gradual changes in forcing. This possibility has attracted great scientific interest in recent years, and has been recognized as one of the greatest threats associated with anthropogenic climate change. Examples of such components, called tipping elements, include the Atlantic Meridional Overturning Circulation, the polar ice sheets, the Amazon rainforest, as w…
Seasonal prediction of Indian summer monsoon onset with echo state networks
Although the prediction of the Indian Summer Monsoon (ISM) onset is of crucial importance for water-resource management and agricultural planning on the Indian sub-continent, the long-term predictability—especially at seasonal time scales—is little explored and remains challenging. We propose a method based on artificial neural networks that provides skilful long-term forecasts (beyond 3 months) of the ISM onset, although only trained on short an…
An early-warning indicator for Amazon droughts exclusively based on tropical Atlantic sea surface temperatures
Droughts in tropical South America have an imminent and severe impact on the Amazon rainforest and affect the livelihoods of millions of people. Extremely dry conditions in Amazonia have been previously linked to sea surface temperature (SST) anomalies in the adjacent tropical oceans. Although the sources and impacts of such droughts have been widely studied, establishing reliable multi-year lead statistical forecasts of their occurrence is still…
