The Earth's climate system is highly nonlinear: inputs and outputs are not proportional, change is often episodic and abrupt, rather than slow and gradual, and multiple equilibria are the norm. While this is widely accepted, there is a relatively poor understanding of the different types of nonlinearities, how they manifest under various conditions, and whether they reflect a climate system driven by astronomical forcings, by internal feedbacks, or by a combination of both. In this paper, after… 
Nonlinear Dynamics of Peatlands and Potential Feedbacks on the Climate System
Peatlands have potential for strong feedback on the global climate system, but their response to future climate change is highly uncertain. In this chapter, I review a range of evidence demonstrating
A hypothesis about double surging climate change in the 20th century
46 The cessation of global temperature growth observed in the past 13 years contradicts the prediction based on the IPCC (Intergovernmental Panel on Cli mate Change) models of general atmosphere and
Identification of Nonlinear Behavior in Transient Climate Change Projections of Soil Moisture over the United States
Abstract While most projections of climate change and its regional impacts focus on overall changes in the state of the climate system, useful information can also be found in the evolution of the
Predicting Climate Change : Lessons From Reductionism , Emergence , and the Past
Climate and Earth system models are the only tools used to make predictions of future climate change. Such predictions are subject to considerable uncertainties, and understanding these uncertainties

TLDR
Results are presented from the integrated global system model (IGSM), which consists of coupled submodels addressing economic development, atmospheric chemistry, climate dynamics, and ecosystem processes, which indicates that the greatest effect of these policies is to lower the probability of extreme changes.
The role of regional climate projections in managing complex socio-ecological systems
Climate is one of many factors to be considered in adapting systems to environmental and societal change and often it is not the most important factor. Moreover, given considerable model
Beyond bifurcation: using complex models to understand and predict abrupt climate change
TLDR
This paper focuses on several climate system components and ecosystems that have been proposed as candidates for tipping points, with an emphasis on ice sheets, the Atlantic Ocean circulation, vegetation in North Africa and Arctic sea ice and the potential of data mining approaches to tackle this problem.
Global Climate Models Exploring the Reliability, Consistency, Limitations, Deficiencies, Uncertainties, and Methods of Global Climate Models in a Nonlinear and Chaotic Climate System
The current climate change dialogue revolves around many different climate elements and their processes but central to the anthropogenic warming hypothesis (some call it a theory but I’m not going to
On Intrinsic Uncertainties in Earth System Modelling
Uncertainties are pervasive in the Earth System modelling. This is not just due to a lack of knowledge about physical processes but has its seeds in intrinsic, i.e. inevitable and irreducible,
Refocusing on the dynamics of the Earth’s climate
Our opinion on the properties of the Earth’s climate system does not coincide with that generally accepted. Statistical analysis shows that, if we put aside the most substantial natural perturbing

Earth system models of intermediate complexity: closing the gap in the spectrum of climate system models
TLDR
A new indicator, called "integration", is introduced, which characterizes the number of interacting components of the climate system being explicitly described in a model, which is closer to comprehensive coupled models of atmospheric and oceanic circulation than to "conceptual" or "box" models.
