In risk communication, both meanings matter: one concerns ecological routes and barriers; the other helps people find and interpret information across climate mitigation, adaptation, and disaster risk reduction.
Two meanings of climate connectivity
The phrase is used in two distinct ways, so it helps to identify which one is meant. Ecological climate connectivity describes how a landscape promotes or hinders organisms moving in response to a changing climate. Knowledge connectivity describes links among climate information, terminology, and organizations that help people discover and use relevant material.
These meanings are related by a common idea—making connections visible—but they are not interchangeable. The first concerns movement through a changing physical environment. The second concerns finding and relating knowledge across fields.
How ecological climate connectivity works
As climate conditions shift, a species may need to move to reach places where its habitat remains suitable. Whether it can do so depends on more than the straight-line distance between its current range and a potential destination. Climate velocity, the distance required to track suitable conditions, resistance along possible routes, and human land uses all shape the pathway. The U.S. Forest Service summarizes these factors in its account of human land uses and climate connectivity.

For example, imagine a forest-dependent species whose suitable climate is moving north. A route through connected forest may offer a relatively passable path. A route interrupted by roads, cities, or intensively used land may impose greater resistance. Even a seemingly open route may not help if suitable climate conditions do not occur along it. Connectivity can make movement more or less feasible; it does not guarantee that a species will successfully shift its range.
A global assessment published in 2023 found that more than half of protected land area and two-thirds of protected units were at risk of climate-connectivity failure under the study’s assessment. The authors considered impediments including distance, human land use, climate conditions along routes, and the absence of analogous climates. This is a finding about the study’s species-agnostic assessment of protected areas, not a forecast that all ecosystems will fail. See the PubMed abstract.
How connected climate knowledge supports communication
Climate information is spread across disciplines, institutions, and online resources. Different communities may use different terms for related concepts, making relevant evidence harder to find or compare. Shared terminology, definitions, synonyms, and notes about a concept’s scope can help people identify what information means and whether it applies to their question.
The Stockholm Environment Institute describes the Climate Connectivity Hub as a search-and-discovery tool spanning climate mitigation, adaptation, and disaster risk reduction. Its taxonomy links concepts and terminology from sources including the IPCC glossary and the UNDRR/ISC Hazard Information Profiles. SEI says the taxonomy covers more than 1,000 concepts and uses semantic data standards and FAIR principles. That is SEI’s description of the tool’s coverage, not an independent assessment of its performance.

According to weADAPT’s description of the Hub, the project responds to siloed online knowledge and communication gaps among people working on climate change. The practical value is navigational: a user can more readily connect terms, organizations, and information that might otherwise remain separated. The Hub is a way to find and relate material; the cited sources do not establish that it is a warning service or that using it reduces risk.
What systemic risk means for risk communication
Climate risks rarely sit in a single, isolated system. The National Academies describes climate change as a complex, systemic threat involving interactions and feedbacks within and between natural and human systems. A climate pressure can affect an ecosystem, infrastructure, livelihoods, or institutions, and those effects can influence one another.
For communication, that systems perspective suggests explaining pathways rather than presenting a hazard as a standalone event. A useful account identifies the initial pressure, the systems it may affect, how effects could spread or reinforce one another, and where uncertainty remains. It also specifies geography: exposure, routes, institutions, and capacity to respond differ by place. This is an application of the National Academies’ framework, not a claim that a particular communication method has been proven to improve outcomes. The framework appears in the 2024 National Academies volume Climate Security in Central America: Proceedings of a Workshop.
A practical way to communicate connectivity and risk
- Clarify the meaning. Say whether “connectivity” refers to organism movement through a landscape or links among knowledge, concepts, and organizations.
- Show the pathway. For ecological connectivity, name the organism, the changing climate suitability, the route, and the conditions or human land uses that may impede movement. For knowledge connectivity, explain which concepts, sources, or institutions are being linked.
- Make relationships legible. Use a map or pathway description for ecological routes, and clear definitions and cross-references for knowledge. Explain how one factor connects to another rather than relying on labels alone.
- State the limits. Distinguish potential movement from successful range shifts, and information discovery from proof of better decisions or reduced risk. Identify geographic scope and uncertainty when they affect interpretation.
- Connect information to a decision. Explain what the evidence can help a reader understand or decide, and what it cannot establish. The IPCC includes ecosystem connectivity among adaptation options and climate services, including early warning systems, among cross-sector options; these are distinct approaches, not interchangeable terms. See the IPCC Working Group II chapter on terrestrial and freshwater ecosystems and its Summary for Policymakers.
How to judge whether a connection is useful
For ecological questions, examine the movement distance or climate velocity, resistance along routes, human land-use barriers, and whether suitable climates exist along possible paths. A route that looks connected on a map may still be unsuitable for a particular species or changing climate.

Best Value
For knowledge tools and communication, consider whether terms are aligned and clearly defined, whether relevant organizations and evidence are discoverable, and whether the material fits the geography, sector, and decision at hand. These are practical evaluation dimensions, not a validated scoring system. Connectivity is most useful when it helps a reader see the relationship that matters without obscuring uncertainty or the limits of the evidence.
