The 2022 Working Group II report from the Intergovernmental Panel on Climate Change, entitled Impacts, Adaptation and Vulnerability, presents “a dire warning about the consequences of inaction” according to the Panel Chair*. Insofar as waterborne transport infrastructure is concerned, the report highlights ports' vulnerability to sea level rise and flooding; their susceptibility to disruption and damage due to changes in wind, wave, heat or fog characteristics; and the potential for less obvious but still important impacts such as those associated with microbiological corrosion of steel marine structures. Low flows will lead to reduced navigability and increased closures of some inland waterways;but extreme high flows or surface water flooding will affect others.
Many sections of this report are relevant to the wider waterborne transport infrastructure sector. An overview of the full report is provided in the Summary for Policy Makers but of note, Chapter 6 focuses on human settlements and infrastructure; Chapter 16 on key risks across sectors; and 17 on Decision Making Options for Managing Risks.
