Revision & Rebuttal (gcb-revision-and-rebuttal)

A GCB major/minor revision is a real chance — but expert reviewers will check whether you actually addressed mechanism, scale, uncertainty, and reproducibility. The response letter must convert each reviewer with evidence while protecting the global-change contribution, and the revised manuscript must stay consistent with the archived data and code.

When to trigger

• A revise decision arrived and you are planning the revision + response letter
• Reviewers disagree and you must reconcile their demands
• A reviewer requests analyses that would change the paper's claims
• Updating the manuscript while keeping the data/code archive in sync

Strategy

1. Treat the handling editor's letter as the global-change rubric. It flags which concerns are decisive — usually the strength of the driver-to-response mechanism, the scale of inference, or the uncertainty treatment. Resolve those before the smaller comments.
2. Answer every reviewer point in a single numbered table. Reproduce each comment, then give your response beneath it; an unanswered comment reads as evasion to expert ecological reviewers.
3. For each comment, either revise or argue back with evidence. Where you complied, cite the new figure/panel/equation/line; where you disagree, ground the pushback in the mechanism, the experimental or modelling design, or the data — a defensible biogeochemical argument lands better than a reflexive concession that erodes the result.
4. Defend mechanism, scale, and uncertainty head-on. GCB referees routinely press on extrapolation from plot to ecosystem/biome, on confounding and pseudoreplication, and on whether uncertainty was propagated — meet each with a new robustness, sensitivity, or ensemble analysis rather than prose.
5. Surface reviewer disagreements rather than papering over them. When two referees pull in opposite directions, name the conflict, pick the path the evidence supports, and explain the tradeoff to the editor.
6. Re-sync the deposited archive. Refresh the data and code (DOI) deposit so every new table and figure reproduces, and revise the data availability statement to match (see gcb-reporting-and-data-policy).

Response-letter format

Per comment, keep the quote-then-answer structure expert referees expect:

> [Reviewer comment, verbatim]

Reply: [the revision made, or the mechanism/design/data reason for disagreeing].
Where: [figure / panel / equation / line number in the revised manuscript].

Lead with a brief editor-facing digest of the headline changes (new mechanism evidence, scale qualifications, added uncertainty analyses); organize by referee; close each item with the exact location so the editor can spot-check quickly.

Triage table for the most common GCB reviewer demands

Sort the comments before drafting. This maps the recurring global-change critique to the response that lands with expert ecological reviewers.

Worked micro-example (illustrative)

A warming-experiment paper draws a major revision. Reviewer 1 calls the soil-carbon feedback "correlative"; Reviewer 2 wants the plot result scaled to the biome. The response adds a structural-equation model isolating the microbial pathway (R1) and an ensemble scaling with a propagated 95% interval labelled as illustrative bounds (R2), then notes the two referees pull in opposite directions on generality and resolves toward the conservative, evidence-supported scale. Each reply cites the new panel and line; the archived code is re-tagged so the figures reproduce. Illustrative.

Anti-patterns

• Folding a comment into the revision silently, with no traceable reply
• Caving to a request that severs the driver-to-response logic just to placate a referee
• A combative or dismissive register toward reviewers
• "We thank the reviewer" attached to no concrete edit or reasoned rebuttal
• Slipping in analyses that undercut the original claim without flagging the shift
• Revised figures whose numbers no longer match the archived data and code
