Experts from the University of Reading have made headlines with their influential contribution to a landmark Nature publication, calling for an urgent global update to climate change risk assessments. Published on 25 February 2026, the comment piece titled "We need a global assessment of avoidable climate-change risks" highlights the critical gap in current international evaluations and urges policymakers to grasp the full scope of threats posed by unchecked emissions. Led by Professor Rowan Sutton, who holds a joint appointment at the University of Reading and as Director of the Met Office Hadley Centre, alongside co-author Professor Tom Oliver from Reading's School of Biological Sciences, the paper emphasizes interconnected risks that could cascade into global instability if not addressed.

This intervention comes at a pivotal moment for UK higher education institutions deeply embedded in climate science. The University of Reading, renowned for its world-leading meteorology and ecology departments, exemplifies how British universities are at the forefront of translating complex climate data into actionable insights. As the UK prepares for its fourth Climate Change Risk Assessment (CCRA4), expected in 2026 to inform the National Adaptation Programme in 2027, Reading's work underscores the vital role of academic research in shaping national resilience strategies.

The Nature Comment: A Call for Comprehensive Global Risk Evaluation

The Nature comment argues that while reports like those from the Intergovernmental Panel on Climate Change (IPCC) provide robust scientific projections, they fall short of a dedicated risk assessment. A true risk analysis would quantify avoidable outcomes under different emissions pathways, revealing what humanity can still prevent through decisive action. Authors including Sutton, Oliver, Peter Stott from the University of Exeter, and others from Bristol, Leeds, and beyond, stress that without this, leaders underestimate cascading effects—from extreme heat triggering droughts and food shortages to floods exacerbating degraded lands.

Professor Sutton notes, "Humanity still has the opportunity to avoid the worst impacts of climate change and shape a more prosperous, liveable future. A global assessment of avoidable climate change risks would enable political leaders and citizens to fully understand what is at stake." Professor Oliver adds, "Climate risks are deeply interconnected... Without understanding these chain reactions, we only see part of the picture." The full Nature comment outlines how such an assessment could prioritize vulnerable regions and guide adaptation funding.

UK's Climate Change Risk Assessment Framework and Reading's Contributions

The UK leads with its statutory Climate Change Risk Assessment (CCRA), mandated every five years under the Climate Change Act 2008. CCRA3, published in 2022, identified 61 priority risks across sectors like health, infrastructure, and nature. The ongoing CCRA4 Independent Assessment, due in 2026, builds on this, with the University of Reading playing a key role through projects like the UK Climate Risk Indicators, which map local threats from floods to wildfires.

In December 2025, Reading scientists released worst-case scenarios for UK lawmakers, projecting year-round cooling demands and 2m sea-level rise under high emissions. This aligns with the Nature call, positioning UK academia as a model for global efforts. Reading's involvement in CCRA technical reports demonstrates how universities bridge science and policy, informing the Adaptation Reporting Power for public bodies.

Spotlight on University of Reading's Climate Research Excellence

The University of Reading boasts one of the world's top meteorology departments, hosting the National Centre for Atmospheric Science (NCAS) and the Pearl (formerly Walker Institute), an interdisciplinary hub for climate resilience. Professors Sutton and Oliver job-share as Associate Pro Vice-Chancellors for Research (Environment), overseeing initiatives like the Hub for Applied Weather and Climate Research (HAWC).

Key groups include Aerosol, Clouds and Climate; Land Surface Processes; and Water@Reading, focusing on hydrology risks. Tom Oliver's applied ecology work explores biodiversity tipping points, while Sutton's climate science informs Met Office projections. This ecosystem has earned Reading Queen's Anniversary Prizes for climate research, attracting funding from UKRI and EU Horizon programs. Reading's announcement amplifies the university's global voice.

Interconnected Climate Risks: Insights from the Paper

• Extreme Heat: Direct health threats, plus indirect via crop failures leading to unrest.
• Drought and Floods: Degraded soils amplify landslides after dry spells.
• Sea Level Rise: Potential abandonment of cities like London.
• Ecosystem Collapse: Tipping points in Amazon or Arctic feedback loops.
• Mass Casualties: Heat exceeding human tolerance limits.

The paper warns these cascades amplify under 2°C+ warming, urging assessments like UK's HILL (High Impact Low Likelihood) scenarios.

Policy Implications for the UK and Global Governance

For the UK, the Nature paper reinforces CCRA4's focus on 127 risks, prioritizing nature-based solutions and infrastructure resilience. Reading's UK Climate Risk Indicators tool allows local authorities to visualize threats, aiding NAP3 planning. Globally, it proposes a UN-mandated framework akin to IPCC but risk-focused, updated regularly with diverse expertise.

Challenges include political barriers and data gaps, but benefits—motivating net-zero transitions and equity—outweigh. UK universities like Reading, Exeter, and Bristol are primed to lead, fostering international collaborations. UK Climate Risk Indicators exemplify practical tools.

UK Universities' Pivotal Role in Climate Science

British higher education drives climate research, with Reading, Imperial, Oxford, and UCL hosting NCAS centres. Funding from UKRI's £2bn climate program supports PhDs and projects. Reading's Pearl integrates social sciences, vital for risk communication.

However, post-Brexit visa issues and funding cuts challenge international talent. Universities advocate for AR6-aligned strategies, training interdisciplinary experts.

Challenges in Conducting Global Risk Assessments

Sutton highlights complexities: regional variations, evolving risks, data silos. Political will is key; emissions pledges lag science. UK model—independent CCC oversight—offers blueprint, but scaling globally requires UN coordination.
