Phys.org / New study identifies sequence of critical thresholds for Antarctic ice basins

The Antarctic ice sheet does not behave as one single tipping element, but as a set of interacting basins with different critical thresholds. This is the finding of a new study by the Potsdam Institute for Climate Impact ...

Phys.org / From power grids to epidemics: Study shows how small patterns trigger systemic failures

Why do some systems collapse suddenly after what seems like a minor disturbance? A single transmission line failure can cascade into widespread blackouts. A delayed shipment can ripple through a global supply chain, emptying ...
