Climate change and health: a literature review example
This climate change and health literature review example shows a transparent path from a broad interdisciplinary question to selected evidence, thematic synthesis, citation checks, and explicit methodological limits.
Start with this questionResearch question
What pathways link climate change exposures to human health outcomes in vulnerable populations?
Search boundary and screening
- Search terms combine climate change, heat exposure, wildfire smoke, air quality, vulnerable populations, public health, displacement, and mental health.
- Screening prioritizes reviews and empirical studies that state population, geography, exposure, and health endpoint.
- Policy recommendations are treated as needs-review unless study design and context are explicit.

Excluded
- Excluded papers without human health outcomes or clear exposure pathways.
- Grouped evidence by heat, air quality, infectious disease, displacement, and mental health.
- Flagged regional generalization and causal inference as review risks.
Included evidence
The evidence table keeps study context visible before synthesis.
| Citation | Study | Population | Finding | Support |
|---|---|---|---|---|
| Heat exposure and mortality review | Public health review | Older adults and heat-exposed communitiesMulti-region evidence synthesis | Heat exposure is consistently linked with mortality and morbidity risk in vulnerable populations. | strong |
| Wildfire smoke respiratory outcomes study | Epidemiological study | Communities exposed to wildfire smokeRegional observational dataset | Air quality pathways require careful reporting of geography, exposure measurement, and confounders. | moderate |
| Climate displacement and mental health review | Interdisciplinary review | Climate-affected and displaced communitiesCross-context qualitative and quantitative evidence | Mental health pathways are plausible but highly context dependent and should not be overgeneralized. | needs review |
Synthesis preview
What the selected evidence says
This public report preview shows how LitSynth can organize climate and health literature into exposure pathways, vulnerable populations, and policy-sensitive evidence gaps. The example groups heat, air quality, displacement, and mental health findings while keeping causal claims visibly bounded. It is designed to show report structure and auditability rather than produce a final policy recommendation.
Citation support check
Exposure-pathway claims are clear, but policy-facing and causal claims require stricter human appraisal.
6 strongly supported claims · 5 need review
Method limits
- Treating the example as a peer-reviewed evidence assessment
- Replacing a formal systematic review or policy appraisal
