Sentences with phrase «equilibrium over timescales»

It is defined as the amount of warming expected if carbon dioxide (CO2) concentrations doubled from pre-industrial levels and then remained constant until Earth's temperature reached a new equilibrium over timescales of centuries to millennia.

Not exact matches

The radiative balance over equilibrium timescales — the heat released by raindrop formation will locally warm the atmosphere, but it takes time for the atmospheric circulation to average this out.

Re 40 simon abingdon — there is very little mass loss to space (can be significant for evolution of conditions over geologic time or in more extreme conditions, but not for Earth like conditions over the timescales over which climatic equilibrium is determined), and latent and sensible heat are transported by conduction and convection and mass diffusion, which can't significantly extend outside the atmosphere.

Over very long time periods such that the carbon cycle is in equilibrium with the climate, one gets a sensitivity to global temperature of about 20 ppm CO2 / deg C, or 75 ppb CH4 / deg C. On shorter timescales, the sensitivity for CO2 must be less (since there is no time for the deep ocean to come into balance), and variations over the last 1000 years or so (which are less than 10 ppm), indicate that even if Moberg is correct, the maximum sensitivity is around 15 ppm CO2 / deg C. CH4 reacts faster, but even for short term excursions (such as the 8.2 kyr event) has a similar sensitivOver very long time periods such that the carbon cycle is in equilibrium with the climate, one gets a sensitivity to global temperature of about 20 ppm CO2 / deg C, or 75 ppb CH4 / deg C.

The potential change in the radiative restoration strength over longer timescales is also considered, resulting in a likely (67 %) range of 1.5 — 2.9 K for equilibrium climate sensitivity, and a 90 % confidence interval of 1.2 — 5.1 K
