Step 1. Understanding prioritisation methodology

Risks do not have the same relevance and urgency to act upon them as there is always uncertainty involved when estimating the impacts of climate change. The relevance of the risks depends on:

The probability: how likely it is that the identified climate hazard occurs?

The magnitude: how extensive is the expected climate hazard and hence
     negative impact and how vulnerable are the exposed elements?

The time horizon: when does or is the hazard and negative impact expected to
     occur?
