Climate Sensitivity Feedback Parameter Calculator
Subtract signed amplifying feedback components from an independently specified positive Planck restoring response, then compute 1/net sensitivity. Requires stable positive net restoring feedback. Components are not inferred from warming; this is not a validated climate forecast.
Description
Amplifying feedback components reduce an adopted restoring magnitude in this sign convention.
Amplifying feedback components reduce an adopted restoring magnitude in this sign convention.1
A positive remaining restoring term is required for the simple reciprocal sensitivity calculation. Use Climate Sensitivity Feedback Parameter Calculator to evaluate the supplied inputs under the model explained below.

How to use Climate Sensitivity Feedback Parameter Calculator and understand its results
- Establish the units, measurement scope and model assumptions before entering values.
- Enter Caller planck restoring w per m2 k, Caller signed amplifying feedback components w per m2 k using the field table and validation rules below, then run the tool.
- Read Net restoring feedback w per m2 k, Conditional sensitivity kelvin per w per m2; interpret the units, signs, ordering and unknown-value placeholders described below.
- Correct reported input errors and rerun. Apply successful results according to their specific meanings and check the assumptions before using them in a decision.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| callerPlanckRestoringWPerM2K | Caller planck restoring w per m2 k | number | Required; constraints below |
| callerSignedAmplifyingFeedbackComponentsWPerM2K | Caller signed amplifying feedback components w per m2 k | array of number | Required; constraints below |
Enter a positive Planck restoring magnitude in W/(m²·K) and finite signed amplifying feedback components in the same unit. Subtract their sum; the net restoring term must be positive. Return that term and its reciprocal in K/(W/m²). Negative components increase modeled restoring feedback under this stated sign convention. No feedback calibration or unstable-branch forecast is provided.
netRestoring=Planck−ΣsignedAmplifyingComponents; sensitivity=1/netRestoring Use the field order, units and branch conditions described above.

}Limitations and assumptions
A positive remaining restoring term is required for the simple reciprocal sensitivity calculation. Apply the exact scope and assumptions explained above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse arrays fail validation. Domain-specific bounds, alignments and supported tokens are explained above; extremely large inputs or outputs can also be rejected. Input errors differ from successful false results, empty match lists and unknown-evidence placeholders.
