Sentences with phrase «total albedo effect»

Not exact matches

Inceasing oxygen (for example form 20.9 to 30 percent) in my opinion would: Increasing scattering and so albedo, lowering temperature Increasing total pressure, broadening of absorption lines, rising temperature Increasing adiabate slope, rising SAT directly but decreasing water vapor, total effect??

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..

Total global snow / ice / albedo effects of course encompass far more than the Arctic sea.

From the figures I took an average value of 0.45 — but, hey, if you prefer to assume 0.35, that's OK, because it will not change the conclusion that the observed Arctic sea ice melt has not appreciably changed our planet's total albedo, and that a very small change in cloud cover would have a far greater effect.

Cloud variations are obviously an important element on a global scale, but the effects of Arctic ice melting are important locally and also a non-trivial fraction of global albedo feedbacks, which are a contributor to total feedback that is smaller than those from water vapor and probably from cloud feedbacks, but not insignificant.

The size and intensity of the polar vortexes then has an effect on the latitudinal position of the jetstreams which then alters total cloud quantities (and reflectance) so as to alter global albedo and thereby alter solar energy input to the oceans.

«his refusal to calculate a total year energy balance» - At this stage, no such calculation can be made, because I have calculated in detail only the changes in the incoming energy (the insolation) as a function of time - of - year and latitude; I have estimated also the effect upon the insolation absorption through a change in the Arctic albedo.

To compute the effect of the interaction of changing seasonal insolation and albedo, he uses albedo data from NASA's Terra satelite, finding a total of 3.674 x 10 ^ 24 Joules of solar energy absorbed over the Gaussian year (equivalent to 228.25 W / m ^ 2 averaged over the globe.

Thus if the two mid latitude jets move equatorward at the same time as the ITCZ moves closer to the equator the combined effect on global albedo and the amount of solar energy able to penetrate the oceans will be substantial and would dwarf the other proposed effects on albedo from changes in cosmic ray intensity generating changes in cloud totals as per Svensmark and from suggested changes caused in upper cloud quantities by changes in atmospheric chemistry involving ozone which various other climate sceptics propose.

For example, the global average effect of any change in albedo from using solar power would be rather small in comparison to mitigation of climate change if that solar power is used (to displace fossil fuels) for a sufficient time period (example: if a 10 % efficient PV panel with zero albedo (reflectivity for solar (SW) radiation) covered ground with an albedo of 25 — 30 %, the ratio of total increased heating to electricity generation would be similar to that of many fuel - combusting or fission - powered power plants (setting aside inverter and grid efficiency, etc., but still it would be similar).
