The mechanisms and conditions for decision-making provide the basis for the chapter. AR5 provided a detailed chapter on the support of climate decision-making. [[IPCC:Wg2:Chapter:Chapter-2|Chapter 2]] of AR5 ( [[#Jones--2014|Jones et al., 2014]] ) concluded, with ''high confidence'' , that risk management provides a useful framework for most climate change decision-making, and that iterative risk management is most suitable in situations characterised by large uncertainties, long time frames, the potential for learning over time, and the influence of both climate as well as other socioeconomic and biophysical changes. Furthermore, decision support is situated at the intersection of data provision, expert knowledge and human decision-making at a range of scales from the individual to the organisation and institution.

The climate risk management decision-making process follows a set of general considerations. The detail of each decision is often highly context specific. Climate risk decision-making is bound to the question of how and under what circumstance it is appropriate to alter, reduce or transfer and retain risk. Different types of risk (e.g., gradual compared with catastrophic) and conditions of risk (e.g., known versus uncertain) are associated with different types of responses (e.g., incremental versus transformational). As the risk decision process proceeds, individuals and organisations will formally or informally utilise any number of mechanisms to guide, aid or facilitate the decision-making process. Decision-making can then take place in a linear set of steps or through a complex iterative process involving reflexive and recursive steps.
