IPW: IPCC warns about climate inaction effects on infrastructure

IPCC report warns about irreversible impact of climate change

In their Climate Change 2022: Impacts, Adaptation and Vulnerability report, the Intergovernmental Panel on Climate Change (IPCC) has issued a stark warning to the world of unavoidable climate change impacts over the coming decades, some of which will not be reversible.

The report explores what that change means for 'human systems', highlighting damages to infrastructure and cities by the sea as some of the most pronounced effects of a worsening climate.

Importantly, weather extremes are happening simultaneously, reverberating across human systems and making the effects more and more challenging to manage and predict.

Faster action is needed on adaptation to climate change alongside mitigation efforts. This is a key focus of COP27 later this year.

According to the IPCC: "So far, progress on adaptation is uneven, and there are increasing gaps between action taken and what is needed to deal with the increasing risks, the new report finds. These gaps are largest among lower-income populations."

However, in a sign of some hope, the IPCC report outlines that multiple climate-resilient development pathways (the process of implementing greenhouse gas mitigation and adaptation measures to support sustainable development) are still possible. However, the window is rapidly narrowing.

The report also stresses the importance of repairing degraded natural ecosystems to unlock nature's potential to reduce climate risks and improve human systems.

On infrastructure, the report finds:

• Climate change is increasingly damaging infrastructure systems globally, with adverse impacts in all regions.
• Infrastructure, including transportation, water, sanitation and energy systems, have been compromised by extreme and slow-onset events, with resulting economic losses, disruptions of services and impacts to wellbeing.
• Key infrastructure systems including sanitation, water, health, transport, communications and energy will be increasingly vulnerable if design standards do not account for changing climate conditions.
• Costs for maintenance and reconstruction of urban infrastructure, including building, transportation, and energy will increase with global warming level.
• Considering climate change impacts and risks in the design and planning of urban and rural settlements and infrastructure is critical for resilience and enhancing human wellbeing.
