Global Change Biology

Global Change Biology (global-change-biology)

Journal positioning

Global Change Biology is the Wiley journal for the biological and ecological responses of the living world to global change — climate warming, elevated CO2, altered precipitation, nitrogen deposition, land-use and land-cover change, and their interactions. Its defining expectation is a clear global-change driver coupled to rigorous biological evidence: a study that links an explicit global-change forcing to a biological or ecological response, with mechanism or consequence resolved from the molecular to the ecosystem scale. A local ecology, physiology, or biogeochemistry study with no global-change driver or framing is a weak fit, however well executed. This skill is a fit / venue-selection / re-framing tool. It does not replace the journal's current author guidelines. Before submitting, re-check the live Global Change Biology submission guidance.

When to trigger

• The author names Global Change Biology and wants a fit/framing check for a global-change ecology or biology paper.
• A local ecological, physiological, or soil/biogeochemical study must be re-framed around an explicit global-change driver and its biological consequences.
• The author is choosing between Global Change Biology, a general ecology journal, and an earth-system or biogeochemistry venue.
• The author needs this journal's global-change-framing requirement and biological-evidence bar.

Scope & topic fit

• Responses of organisms, populations, communities, and ecosystems to climate change, elevated CO2, warming, drought, and shifting disturbance regimes.
• Terrestrial, freshwater, and marine carbon, nutrient, and greenhouse-gas cycling when the biological response to a global-change driver is central.
• Land-use and land-cover change, nitrogen deposition, and their interactions with climate on biodiversity, productivity, and biogeochemistry.
• Phenology, range shifts, species interactions, and evolutionary/acclimation responses under global-change forcing.
• Mechanistic, manipulative experiments (warming, FACE, N-addition), long-term observations, syntheses, and process-based or data-driven modeling of global-change responses.
• Feedbacks between the biosphere and the climate system, including mitigation/adaptation relevance grounded in biological evidence.

Method & evidence bar

• A global-change driver must be explicit and causally connected to the biological response — not a study where climate is mentioned only in the framing sentences.
• Manipulative experiments need appropriate replication, realistic treatment levels, and controls; pseudoreplication and unrealistic forcing levels are common failings.
• Observational and gradient studies must address confounding, space-for-time assumptions, and the limits of attribution to the global-change driver.
• Models must be evaluated against data with skill metrics and uncertainty; scenario and parameter choices must be justified and sensitivity explored.
• Syntheses and meta-analyses need a transparent, reproducible search, effect-size handling, and heterogeneity/bias assessment.
• Conclusions about consequences must match the scale of evidence — extrapolation from one site or one season to ecosystem- or global-scale claims must be justified.

Structure & house style

• Standard research-article structure; the journal also publishes reviews, syntheses, and shorter formats — re-check current article types and length on the live guide.
• The introduction must foreground the global-change driver, the biological question, and the knowledge gap, framing the work for a broad global-change readership.
• Figures should be quantitative and mechanism- or consequence-oriented (response curves, treatment contrasts, maps with uncertainty), not purely descriptive site characterizations.
• Methods, data, and code must support reproducibility; follow the journal's data-availability expectations and deposit data/code where required.
