What it is
This topic sits at the intersection of physical climate science (see Climate Science Fundamentals) and financial or operational decision-making.
Physical risk vs. transition risk
Two categories of risk, both introduced briefly in Climate Science Fundamentals, get fully unpacked here:
- Physical risk — direct exposure to climate hazards. It splits into acute risk (sudden extreme events: hurricanes, wildfires, floods) and chronic risk (gradual, ongoing shifts: sea level rise, rising average temperatures, changing precipitation patterns).
- Transition risk — financial or business risk created by the shift away from fossil fuels: stranded assets (infrastructure that loses value because it becomes obsolete or unusable), changing regulation, and shifting consumer or investor preferences.
A concrete way to tell them apart: a beachfront property losing value because a hurricane destroyed it is physical risk. The same property losing value because insurers stopped covering that zip code is transition risk showing up early.
Mitigation vs. adaptation
Mitigation vs. adaptation organizes almost everything else in this space. Mitigation means reducing emissions to slow climate change; most of the rest of this hub is about mitigation. Adaptation means adjusting to climate impacts that are already happening or already locked in regardless of future emissions: sea walls, drought-resistant crops, building codes designed for higher heat. Resilience is the broader capacity of a system (a city, a supply chain, a company) to withstand and recover from climate shocks. It’s closely related to adaptation but describes the outcome rather than the action.
Climate risk modeling and analytics
Climate risk modeling and analytics, the software category referenced in the Climate SaaS topic, quantifies physical risk exposure for a specific asset or location, typically expressed as something like “this property has an X% annual flood probability by 2050 under a given warming scenario.” These models often borrow value at risk (VaR) framing from finance — VaR is a standard finance metric for the size of a potential loss — translating physical exposure into expected annual damages or insured losses so that risk and finance teams, not just scientists, can act on the output directly.
Climate scenarios
Climate scenarios are standardized warming pathways (the IPCC uses a set of these, often labeled RCP or SSP scenarios in the underlying literature) that let a model show different outcomes depending on how much the world actually decarbonizes, rather than a single fixed prediction.
Insurance markets
Insurance markets are one of the clearest real-world signals that physical risk is already materializing financially. Rising claims from climate-related disasters are pushing insurers to raise premiums sharply or withdraw entirely from high-risk markets — wildfire zones, coastal flood zones — well before those risks show up in most other financial or policy signals.
Managed retreat
Managed retreat is a more contested adaptation strategy: deliberately relocating people and infrastructure away from areas that are becoming increasingly uninhabitable or uninsurable, rather than continuing to rebuild in place after each disaster.
Why it matters
Insurance, real estate, and finance buyers are the ones this sector makes physical climate science actionable for — the same buyer groups called out in the Climate SaaS topic’s climate risk analytics subcategory. Understanding the physical-risk vocabulary from Climate Science Fundamentals and the transition-risk vocabulary from Climate Policy & Economics is what makes a risk analytics product’s pitch, and its buyer’s actual concerns, legible.
