An emissions‐based view of climate forcing by methane and tropospheric ozone

Shindell, Drew T., Faluvegi, Greg, Bell, Nadine, Schmidt, Gavin A.·2005·Geophysical Research Letters

Abstract

We simulate atmospheric composition changes in response to increased methane and tropospheric ozone precursor emissions from the preindustrial to present‐day in a coupled chemistry‐aerosol‐climate model. The global annual average composition response to all emission changes is within 10% of the sum of the responses to individual emissions types, a more policy‐relevant quantity. This small non‐linearity between emission types permits attribution of past global mean methane and ozone radiative forcings to specific emissions despite the well‐known non‐linear response to emissions of a single type. The emissions‐based view indicates that methane emissions have contributed a forcing of ∼0.8–0.9 W m−2, nearly double the abundance‐based value, while the forcing from other ozone precursors has been quite small (∼−0.1 for NO x, ∼0.2 for CO + VOCs).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
