Sentences with phrase «solar forcing scenarios»

Their abstract says «energy budget calculations show that poleward atmospheric energy transport increases more in solar forcing compared to equivalent CO2 forcing simulations, which is in line with the identified strong increase in large - scale precipitation in solar forcing scenarios.»

Not exact matches

Santer et al in the PNAS paper also provide some additional tests in examining scenarios with much greater solar and volcanic forcings than observed in the real world.

They maintain that the actual forcings (which includes things other than just CO2) are closest to Hansen's scenario B. Remember this wasn't an exercise in predicting future CO2, methane, solar, volcanic, etc. forcings, but a prediction of what could happen under some hypothetical «high», «medium» and «low» forcing scenarios.

It may well be the case that only the systems that produce forcings eg volcanic eruption, solar winds, sunspot activity and the like could be non ergodic but still capable of yielding scenarios for climate modelling purposes.

Figure 2: Global mean temperature anomalies 1900 to 2100 relative to the period 1961 to 1990 for the A1B (red lines) and A2 (magenta lines) scenarios and for three different solar forcings corresponding to a typical 11 - year cycle (solid line) and to a new Grand Minimum with solar irradiance corresponding to recent reconstructions of Maunder - minimum irradiance (dashed line) and a lower irradiance (dotted line), respectively.

The larger the MWP temperature rise in this scenario, the larger the TCR, and the same feedbacks both positive and negative will operate for solar and CO2 forcing.

The influence of reduced solar forcing (grand solar minimum or geoengineering scenarios like solar radiation management) on the Atlantic Meridional Overturning Circulation (AMOC) is assessed in an ensemble of atmosphere — ocean — chemistry — climate model simulations.

Well, there is a lot of magical thinking built into the models, from unrealistic emission scenarios that disregard proven fossil fuel reserves, to made up sensitivity values from overestimated aerosol forcings and underestimated solar forcings, and made up feedbacks.
