Abstract This review article provides a synthesis and perspective on how weather climate extreme events can play role in influencing tipping elements triggering points the Earth System. An example of potential critical global point, induced by extremes an increasingly warmer climate, is Amazon rainforest dieback that could be driven regional increases droughts exacerbated fires, addition to deforestation. A element associated with boreal forest might also vulnerable heat, drought fire. oceanic collapse Atlantic meridional overturning circulation due variability freshwater inputs, while marine heatwaves high acidity lead coral reef collapse.

From historians to forecasters: The potential of bivalve records to assess resilience and provide early warnings for marine tipping points

Abstract Amidst the ongoing climate crisis, need for observation‐based prediction of environmental tipping points becomes increasingly urgent. Detecting loss resilience within a system can provide early warnings points. This requires long, regularly spaced time‐series, characteristics that are rare among marine observational and proxy records. Due to their remarkable length temporal resolution, records from bivalve shells offer unique opportunity assessing in environment. Here, we investigate suitability measuring changes two indicators, autocorrelation variance. We find increment‐width typically considered robust reliable assessments. However, while is generally indicator series, variance may exhibit biases mainly associated with age‐related effects. work provides guidelines obtaining assessments records, unlocking potential
