Summary
DescriptionGreenhouse Effect metrics time series.svg
English: Increase in the Earth's Greenhouse effect over the period 2000-2022 according to three different metrics, (a) G = SLR - OLR, (b) g̃ = 1 - OLR/SLR, and (c) ΔTghe = (SLR/σ)1/4 - (OLR/σ)1/4, where OLR = outgoing longwave radiation, SLR = surface-emitted longwave radiation, and σ = Stefan-Boltzmann constant. Data is from the CERES EBAF version 4.2 dataset for the period 2000-03 through 2022-12 (see https://ceres.larc.nasa.gov/data/). OLR and SLR are global averages, subject to a 12-month rolling average to eliminate seasonal variations. (Data for a given date averages data from 6 months prior through 6 months after the indicated date.)
