Sentences with phrase «changing planetary albedo»

Essentially, every timestep the model calculates the forcing from CO2 and reduces incoming solar radiation to offset that, taking changing planetary albedo into account.
Arguing against greening because it might marginally change planetary albedo is madness — madness I say.

Not exact matches

Whilst several methods for counteracting climate change with geoengineering are considered feasible, injecting sulfates or other fine aerosols into the stratosphere, thereby increasing planetary albedo, is a leading contender.
Since it reflects the capacity of the climate system to absorb heat, it may be influenced by the planetary albedo (sea - ice and snow) and ice - caps, which respond to temperature changes.
These findings are remarkable insofar as they indicate that anthropogenic perturbations of the planetary albedo, such as sulphur emissions and / or land - use changes, or natural variations in insolation and CO2 concentration could trigger abrupt transitions between different monsoon regimes.
It is well known that multiple factors are involved, including the change in planetary albedo, change in nitrous oxide concentration, change in methane concentration, and change in CO2 concentration.
However, even a smaller figure (I had calculated about 0.17 W / m ^ 2 based on your inflated figure for total planetary albedo, but you can check it out) is still significant when compared with the total flux imbalance, which I think is a more informative comparison than an arbitrarily selected change in cloud cover, because it compares the sea ice reduction with the effects of all climate variations that have been operating in recent years..
The identified atmospheric feedbacks including changes in planetary albedo, in water vapour distribution and in meridional latent heat transport are all poorly represented in zonal energy balance model as the one used in [7] whereas they appear to be of primary importance when focusing on ancient greenhouse climates.
, a change in planetary albedo (forest die off?)
The cause could be any short or long term change in a number of things solar output, ocean heat release, planetary albedo, vapor, whatever.
Rayleigh - Benard Convection cloud physics result in changes in planetary albedo.
In order to determine the solar contribution, we have to start with the solar radiative forcing, which is the change in total solar irradiance (TSI) in Watts per square meter (W / m2) divided by 4 to account for spherical geometry, and multiplied by 0.7 to account for planetary albedo (Meehl 2002).
Global temps vary for many reasons beyond CO2 levels including but not limited to: planetary motion, changes in albedo, stratospheric aerosols, and solar variability to name a few, but the only area of genuine study by the IPCC has been rising CO2 levels.
Greenhouse warming that is stronger over land and in the Northern Hemisphere tends to strengthen the monsoon, but increases in planetary albedo over the continent due to aerosol forcing and / or land - use change tend to weaken it.
The black line, reconstructed from ISCCP satellite data, «is a purely statistical parameter that has little physical meaning as it does not account for the non-linear relations between cloud and surface properties and planetary albedo and does not include aerosol related albedo changes such as associated with Mt. Pinatubo, or human emissions of sulfates for instance» (Real Climate).
In the past few years several attempts have been made to assess changes in the Earth's planetary albedo, and claims of global dimming and more recently brightening have been debated in journal articles and blogs alike.
Part of the changes in the spatial correlations is expected to be due to convection and clouds, which too play a role for the GHG, in addition to influencing the planetary albedo.
I would not regard heat being stored in the ocean and melting snow / ice but not completely melting it (and thereby changing the surface albedo), since this does not have any sort of direct change to the planetary radiative fluxes.
