Climate-Risk PhD: Modelling How Extreme Weather Cascades Across UK Infrastructure

Climate-Risk PhD: Modelling How Extreme Weather Cascades Across UK Infrastructure

Quick Decision

This Exeter PhD is expected to start in September 2027. Its three linked tasks are clear: model hazard damage in one infrastructure sector; trace compound events and service cascades across connected systems; and estimate the resulting economic losses for finance, insurance and policy users. The project specifies probabilistic UKCP18 projections and infrastructure-network data, but leaves the starting sector, datasets, damage functions and loss-valuation method open. Those choices will determine whether the scope is feasible within 3.5 funded years. (Project description)

Exeter's interdisciplinary climate-risk environment and the UK's adaptation priorities make the topic timely, but do not resolve the practical questions. The EPSRC Doctoral Landscape Award deadline is midday on Tuesday 8 December 2026. Funding covers up to 3.5 full-time years, whereas Exeter permits up to four years of full-time PhD registration. Before applying, confirm the starting sector and secured datasets, the registration route, and the plan for completing the thesis within the funded period.

Research Problem and Doctoral Work

The research problem is to move beyond isolated hazard-and-asset estimates and represent both compound hazards and cascading service failures. The project uses heat and drought occurring together as a compound example. It describes a cascade in which flooding disrupts power, with knock-on effects for water treatment and transport. These involve related but distinct analytical questions: the first concerns co-occurring or connected hazard conditions; the second follows dependencies between infrastructure systems.

The advertised work has three stages:

1. Develop rigorous hazard-damage modelling for one infrastructure sector.
2. Extend it to quantify compound and cascading pathways across interconnected systems.
3. Translate physical risk into economic-loss estimates relevant to investors, insurers and policymakers.

Probabilistic UKCP18 projections and infrastructure-network data are explicit inputs. The project description does not name the first sector, hazard combinations, climate scenarios, vulnerability/damage functions, network representation, service recovery assumptions, validation datasets or economic valuation method. Those choices will shape the thesis scope. Candidate methodological questions include how uncertainty propagates from climate projections through asset damage and network dependencies into total losses; whether alternative dependency definitions change results; and whether system-wide aggregation hides spatially uneven impacts. These are possible analytical angles, not confirmed work packages or promised findings.

A 2025 systematic review catalogued 366 peer-reviewed compound-event papers published between 2012 and 2022 and found rapid growth, while infrastructure damage and energy-infrastructure impacts remained comparatively underrepresented. A 2024 urban-infrastructure study showed how indirect effects can be missed in isolated-asset analysis and how consequences differ across communities. A separate systematic review describes multiplex networks as one approach for modelling interdependent infrastructure, while highlighting choices about dependency structure, system evolution and resilience metrics. These sources show a relevant research frontier; none establishes the methods Exeter will use. (Compound-event review, real-world infrastructure cascade study, multiplex-network review)

School, Programme and Field Context

The project is based in the University of Exeter's Department of Geography at Streatham, in the Laver Building. The project PDF lists PhD Environmental Intelligence and PhD Geography as potential registration routes; it does not say which route will be used. Exeter's Geography research-degree page describes Human and Physical Geography, full-time and part-time study, and Streatham and Penryn locations. The University of Exeter is the identified degree-awarding institution; no joint degree or outside host institution is named. (Project description, Geography research degrees)

Exeter reports Geography in the top 40 of the 2026 QS World University Rankings by Subject; its March 2026 news announcement gives the exact position as 38th globally. The Geography page also reports 6th in the UK for world-leading Geography and Environmental Studies research based on 4-star outputs in REF 2021. These are relevant subject indicators, not measures of the project's admission odds or individual supervision quality. Geography is linked to the Global Systems Institute (GSI), which brings climate researchers together with industry, policymakers, NGOs and other stakeholders. The Resilience and Physical Climate Risk network combines climate science, risk assessment and systems thinking and lists both supervisors. (Geography PGR and subject indicators, QS 2026 subject results, REF 2021 results, GSI, physical climate-risk network)

Exeter sets a maximum of four years for full-time PhD registration. The DLA funds this studentship for up to 3.5 years full time. The four-year maximum does not guarantee four years of stipend or fee support; confirm the expected submission date, any writing-up period, and the position on tuition and stipend after the funded period. (Degree duration rules, DLA funding terms)

Supervisor and Lab Assessment

The project document identifies Jesse Abrams as lead supervisor (j.abrams@exeter.ac.uk) and Richard Betts as additional supervisor. Betts is Head of Climate Impacts Research at the Met Office Hadley Centre and a Professor at Exeter; his profile lists climate-impact projections and risk assessment among his expertise. Exeter's GSI and physical-climate-risk network provide an interdisciplinary setting for linking climate science, network risk and economic analysis. Public pages do not confirm a dedicated project team, external partner commitments, student cohort, meeting schedule or project-specific data access. (Project description, Betts profile, GSI, network)

Recent works by the supervisors and their research network illuminate several parts of the proposed pipeline:

• In Regional impacts poorly constrained by climate sensitivity (2024), Betts and co-authors compare projected drivers of floods, droughts and wildfires across climate models. They find that regional impact-driver changes are not reliably predicted by each model's global climate sensitivity, cautioning against selecting impact ensembles on that metric alone. The PhD implication is to justify climate-projection uncertainty treatment; the paper does not model infrastructure networks. (Earth's Future, 2024)
• Abrams's 2026 commentary Climate risk is not climate determinism argues that climate-to-economy pathways are structurally uncertain and that scenario stress tests examine adverse possibilities rather than forecast them. This is relevant to communicating uncertainty in economic-loss estimates, but it is a commentary rather than empirical infrastructure research. (Dialogues on Climate Change, 2026)
• A 2025 UCL working paper co-authored by Abrams maps firm-level and spatial data into financial-flow networks linked to land-use pressures. It is a useful example of networked environmental-to-financial transmission, but concerns ecosystems rather than infrastructure and remains a working paper. (UCL IIPP Working Paper 2025-10)
• The 2023 Nature Sustainability paper Quantifying the human cost of global warming, by Lenton, Xu, Abrams and colleagues, combines climate and population data at about 10-km resolution to quantify exposure to unprecedented heat. It demonstrates spatial exposure analysis, not infrastructure damage or monetized loss. (Nature Sustainability, 2023)

A 2026 report co-authored by Abrams, Recalibrating Climate Risk, argues that conventional economic models may underrepresent extremes, compounding shocks and cascading effects. It draws on expert elicitation and is useful as an agenda signal, but it is a policy/industry report rather than peer-reviewed research. (Report)

Funding, Application, and Living Cost

Item	Current published terms
Scheme and start	September 2027 Exeter EPSRC Doctoral Landscape Award; up to 16 funded places across the call.
Application deadline	Midday, Tuesday 8 December 2026. Project-led call; maximum three project applications. Use the chosen project's application link.
Funding	University tuition fees, indexed stipend for up to 3.5 full-time years (current 2026/27 rate £21,805/year), and £5,000 Research Training Support Grant over 3.5 years. The 2027/28 rate is not stated.
International eligibility	Limited full studentships for international students, up to 30% of the cohort. Exeter says international awardees receive a university fee-waiver top-up so full tuition is covered. Visa, healthcare surcharge and relocation remain the student's responsibility.
General academic threshold	Normally a UK First or Upper Second (or overseas equivalent) in an appropriate science, engineering or technology area. Lower Second applicants may be considered with a Master's or significant relevant non-academic experience. The project PDF lists no additional project-specific entry requirement.
Application materials	Project-named personal statement, CV, transcripts, two references and, where required, English-language evidence. Documents must be in English; academic-qualification translations must be certified. Referees should email institutional-address letters by 15 February 2027.

These are scheme-level terms and remain subject to eligibility and award. The £21,805 figure is the current published 2026/27 UKRI minimum; the stipend is indexed, so verify the amount in the final offer. The central call gives a likely interview period of 15–24 February 2027, but a later section still says interviews begin in February 2026 and outcomes are due in March 2026. The application deadline is consistent; ask Exeter to confirm the current interview timetable. The reference deadline is 15 February 2027, close to the stated interview window, so referees should be contacted early. (DLA call, eligibility, funding and application guidance, UKRI stipend table)

Exeter's April 2026 estimate for a single student's basic living costs is £1,300–£2,000 per month, or £316–£421 weekly. The current stipend averages about £1,817 monthly, leaving relatively little margin at the upper end. One postgraduate self-catered room at Cook Mews costs £5,470.74 for a 44-week 2026/27 contract (£124.74/week); it is one example, not guaranteed housing or a full-year budget. International applicants should separately plan for visa, healthcare surcharge and moving costs. The £5,000 RTSG is research/training support, not additional living income. (Exeter budget estimate, Cook Mews 2026/27 prices)

Applicant Fit and Preparation

Formal requirements. The project PDF says “Project specific entry requirements: none.” General DLA academic and residence criteria still apply, as may the chosen programme's own rules. Applicants who need English-language proof must provide it before starting. Applications must use the project-specific route; incomplete or incorrectly routed submissions will not be considered for funding. (Project description, DLA guidance)

Backgrounds that map naturally to the work. Quantitative physical geography, climate science, environmental modelling, infrastructure/civil engineering, statistics, applied mathematics, network science, economics or risk analysis can connect to one or more project stages. The advertised training spans climate science, infrastructure-risk engineering, network analysis and economic-risk quantification. It is a stronger match for applicants willing to build and validate quantitative models than for a research plan centered only on qualitative fieldwork; this is an interpretation of the outputs, not an extra admission rule.

Useful preparation, not stated prerequisites. Demonstrate quantitative research, probability/statistics, computational data handling, spatial analysis or graph/network methods where available. Python/R, GIS, infrastructure-system knowledge and economic-loss accounting are sensible preparation, but none is listed as a formal prerequisite. A project-specific statement can connect prior work to the sequence from hazard damage through network effects to loss estimates, identify an infrastructure sector of interest, and show awareness of open modelling choices. UKCP18 includes probabilistic products and spatially detailed projections; ask which version, variables and horizons are intended. (UKCP18 overview, UKCP probabilistic-products FAQ)

Career Pathways and Market Context

The advertised work may lead toward applied climate-risk analysis, infrastructure and utility resilience, public adaptation, engineering or environmental consulting, and physical-risk assessment in finance or insurance. A national infrastructure-pipeline update estimates average annual infrastructure and construction workforce demand of 629,000–706,000 over five years, alongside a 734-project, £718 billion pipeline. That is a broad workforce signal, not a count of climate-risk analyst vacancies. A 2026 engineering report also calls for infrastructure adaptation and stress-testing against compound extremes and dependencies. These sources show adjacent applications for the project’s skills, but they provide no specialist vacancy count, salary estimate or graduate-destination data.

Next Actions and Questions to Verify

Before Applying

• Email lead supervisor Jesse Abrams at j.abrams@exeter.ac.uk with a concise note on your infrastructure-sector interest and quantitative methods. Ask which sector starts the work and whether its asset/network data are already secured and licensed for research.
• Confirm whether registration would be in Environmental Intelligence or Geography, which route-specific entry rules apply, and whether programming, statistics or GIS is expected before arrival.
• Request the current application link and confirm it routes to the correct panel. Prepare the project-named statement, CV, transcripts and two referees; allow time for certified translations and any English evidence.
• Treat 12:00 on 8 December 2026 as the application cutoff. Ask Exeter to confirm interview timing because the guidance includes a stale 2026 date statement.

At Interview

• Ask how the single-sector model, multi-system dependencies and economic-loss stage will fit within 3.5 funded years.
• Discuss climate-projection choices, dependency assumptions, validation and uncertainty propagation. Clarify whether finance, insurance or government users are committed collaborators or engagement opportunities to be arranged.
• Confirm supervisory roles, meeting cadence, access to collaborators and the technical/general interview format.

Before Accepting an Offer

• Obtain written confirmation of stipend by year, tuition coverage, any international fee-waiver top-up and exact funding dates.
• Confirm registration and submission dates, any writing-up period, support after 3.5 years and how the chosen route applies Exeter's four-year maximum.
• For an international offer, verify visa/IHS, relocation and other excluded costs, plus realistic housing cost and availability.
