Large, abrupt, and widespread climate changes with major impacts have occurred repeatedly in the past, when the Earth system was forced across thresholds. Although abrupt climate changes can occur for many reasons, it is conceivable that human forcing of climate change is increasing the probability of large, abrupt events. Were such an event to recur, the economic and ecological impacts could be large and potentially serious. Unpredictability exhibited near climate thresholds in simple models… 
Abrupt Climate Change
Changes in Holocene climate have generally been gradual and the environmental security effects have been manageable. However, the long–term Holocene climate record also indicates that significant
Abrupt climate change: Debate or action

Global abrupt climate changes have been documented by various climate records, including ice cores, ocean sediment cores, lake sediment cores, cave deposits, loess deposits and pollen records. The
Abrupt Change in Earth's Climate System
▪ Abstract Many aspects of Earth's climate system have changed abruptly in the past and are likely to change abruptly in the future. Although abrupt shifts in temperature are most dramatic in glacial

Ecosystem Responses to Abrupt Climate Change: Teleconnections, Scale and the Hydrological Cycle
The occurrence of past and future abrupt climate change, such as could occur under thermohaline circulation (THC) weakening, is increasingly evident in the paleoclimate record and model experiments.
Abrupt changes in Great Britain vegetation carbon projected under climate change
TLDR
It is shown that numerous climate-driven abrupt shifts in vegetation carbon are projected in a high-resolution model of Great Britain's land surface driven by two different climate change scenarios, and it is found that abrupt ecosystem shifts associated with increases (rather than decreases) in vegetation Carbon, show the greatest potential for early warning signals.
Abrupt Climate Change in an Oscillating World
TLDR
It is shown how abrupt and sometimes even irreversible change may be evoked by even small shifts in the amplitude or time scale of environmental oscillations, including terrestrial ecosystems, Arctic sea ice and monsoons.
Change And Variability In The Global Climate System: Past, Present, And Future
Global Climate Change is an issue that has garnered tremendous public attention and captured headlines. However, many people do not have a good understanding of what is natural, what is not, or how
Abrupt change in climate and climate models
Abstract. First, we review the evidence that abrupt climate changes have occurred in the past and then demonstrate that climate models have developing capacity to simulate many of these changes. In
