Sentences with phrase «forcing during the historical period»

Their argument is that the mix of types of forcing during the historical period underestimate ECS in their model, corresponding to a composite efficacy of less than one.

If that were the case in the real climate system, then estimates of ECS from observed changes in GMST and total forcing during the historical period would underestimate true ECS, which relates to pure CO2 forcing.

(See Miller et al 2014 p. 449; this study has lots of good information about forcing during the historical period in GISS ModelE2.

Not exact matches

This means the global mean temperature (GMST) response to the aggregate forcing applying during the historical period (actually, 1906 — 2005) was identical, in the model, to the response to the same forcing from CO2 only.

But CO2 was only 60 % of the positive forcing during this period, so we're actually talking about 0.5 ºC per 1500GtCO2 for the historical record.

... it seems clear that no massive ocean temperature anomaly [i.e., cooling] did in fact develop during the historical period [due to Land Use forcing].

Marvel et al could withdraw their paper and submit a new one, using more satisfactory methodology and providing more detail, after performing a set of simulations that showed how the GISS model responded to each type of forcing as the climate state evolved during the historical period.
