This article explores the influence of personal values and ontological beliefs on people’s perceptions of possible abrupt changes in the Earth’s climate system and on their climate change mitigation preferences. The authors focus on four key areas of risk perception: concern about abrupt climate change as distinct to climate change in general, the likelihood of abrupt climate changes, fears of ...

In this short paper, a novel approach that combines global and local information to detect abrupt and gradual shot changes is proposed. In this approach, abrupt shot change is detected by an adaptive threshold computed from DC frame histogram difference with a sliding window. To detect gradual shot changes, this work performs an analysis of blockwise histogram difference with a statistical mode...

Abstract. We propose a conceptual model comprising cascade of tipping points as mechanism for past abrupt climate changes. In the model, changes in control parameter, which could instance be related to atmospheric circulation, induce sequential sea ice cover and ocean's meridional overturning circulation. The ocean component, represented by well-known Stommel box is shown display so-called rate...

Paleoclimatic data is increasingly showing that abrupt change is present in wide regions of the globe. Here we present a mechanism for abrupt climate change with global implications. Results from a tropical coupled ocean-atmosphere model show that under certain orbital con gurations of the past, variability associated with El Ni~ no/Southern Oscillation (ENSO) physics can abruptly lock to the s...

A large number of shot boundary detection, or equivalently, transition detection techniques have been developed in recent years. The shot boundary detection includes abrupt and gradual shot change detection. Gradual shot change detection is more challenging task than abrupt shot change detection. Thus aim of this paper is mainly to focus on gradual boundary detection. Previous researches relate...
