We will provide urgently-needed evidence for decision-making to respond to climate change; mapping future marine and coastal hazard ‘hotspots’, identifying adaptation strategies, knowledge gaps, and research directions to ensure subsea telecom infrastructure is resilient to climate change impacts. This multi-disciplinary project is thus well aligned with COP26 ‘Action on Adaptation’ and NERC’s Resilient Environment priority.
We build on previous NERC-funded research; making use of global model projections of climate change effects on storms, waves and coastal inundation, and extending analysis of a global database of cable damage that assessed past impacts of individual hazards (identifying landing stations and shallow cables as highly vulnerable). International partners extend UK-capacity, particularly in compound hazards, modeling of storm surges, impacts and design of infrastructure.
The following outputs will shared with project partners and stakeholders and hosted on a project website:  Catalogue spatio-temporal trends in past cable damage (as a heat map and timeline) to document first evidence of climate change-related impacts over the last 35-40 years (to be submitted as peer-reviewed paper).  Climate Change Risk Register, summarizing hazards for cables (including emerging hazards), and their anticipated future frequency, magnitude, location and impacts under IPCC Shared Socioeconomic Pathways.  Map future climate change ‘hotspots’ to assess future resilience; i.e. which cables, landing stations, regions, countries and cities are most vulnerable, when and where adaptation is required.  White Paper summarizing guidance for cable routing/design to adapt to climate change scenarios, and roadmap of research/collaborations required to fill remaining knowledge, data, and certainty gaps.
