Field overview

Hazard science studies the natural processes that can cause harm: atmospheric extremes such as heat, storms and heavy rain; hydrological extremes such as floods and drought; fire; and geophysical events such as earthquakes, volcanic eruptions, landslides and tsunamis. Climate science adds the long view, explaining how the statistics of weather are changing. This page defines the field, explains why it matters and shows how it connects to other risks.

01In brief

The short answer.

The Climate and Hazards field covers physical climate risks, weather extremes and hazard interactions grounded in observed and modelled evidence. Experts in it study questions such as climate baselines and heat and drought, with methods such as climate and atmospheric science as well as Earth and geophysical science. Its counterparts at GRF and GRA look at the same systems through governance and finance.

04Why it matters

Every risk assessment starts from a hazard estimate.

Building codes, flood defences, insurance prices, crop plans, water allocations and public health warnings all rest on an estimate of how often and how severely a hazard will occur. Historically those estimates were drawn from the observed record on the assumption that the future would resemble the past. For climate-driven hazards, that assumption no longer holds, and the observational record itself is short relative to the rare events that matter most.

The field therefore combines observations, physical understanding and models to estimate hazards that may not yet have been observed at a given place. Doing so honestly, with clear uncertainty, is one of the main contributions science can make to risk management.

05What experts study

The core questions.

  1. 01

    Change and attribution

    How hazards have changed and how much of that change is attributable to warming. See climate baselines.

  2. 02

    Individual hazards

    The physics and statistics of heat, drought, floods, storms, fire and geohazards. See heat and drought, flood and storm, wildfire and land and earthquakes and geohazards.

  3. 03

    Interactions

    How hazards combine and cascade. See compound hazards.

  4. 04

    Futures

    What scenario models project and how far to trust them. See climate projections.

  5. 05

    Use

    How hazard information reaches decisions. See climate services and warnings.

06Connections

How hazards touch other systems.

Hazards matter through exposure and vulnerability: the people, assets and services in harm's way and their capacity to cope. That is why this platform links to Disaster Resilience and Recovery, Critical Infrastructure and Water Nexus within GCRI, and to counterparts at The Global Risks Forum (GRF) and The Global Risks Alliance (GRA), such as Reinsurance and Catastrophe. Dependencies and consequences maps the links.

07Key terms

Terms used on this page.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.

TermDefinition
Compound eventTwo or more hazards or drivers occurring together or in sequence whose joint impact exceeds what either would cause alone, such as drought followed by intense rain; IPCC assessments use the term.
Early warning systemAn integrated system of hazard monitoring, forecasting, risk assessment, warning communication and preparedness that lets people and institutions act before a hazard strikes, in UNDRR terminology.
Climate servicesThe provision of climate information in ways that help people and organizations make decisions.
Systemic riskRisk arising from the interactions and dependencies within and between systems, where a shock can propagate and threaten the functioning of the whole.
08Methods

What the evidence rests on.

The field draws on climate science, geoscience, extreme value theory, Earth observation and forecasting. Assumptions and limits are set out on methods and uncertainty.

10Questions

Questions and answers.

What is the difference between a hazard and a risk?
A hazard is a process or event that can cause harm, such as a flood. Risk combines the hazard with exposure, meaning what is in harm's way, and vulnerability, meaning how susceptible it is to damage.
Are earthquakes affected by climate change?
Earthquakes are driven by tectonic processes and are not caused by climate change. They are part of this field because they threaten the same exposed societies and interact with other hazards, for example when an earthquake triggers landslides.
Which methods does the field rely on?
Climate and atmospheric science, Earth and geophysical science, forecasting, extreme value theory, Earth observation, spatial statistics, high-performance computing, hydrology, ocean science and space systems. See the STEM foundation page.
