Sentences with phrase «global albedo»

Figure 1: Global albedo change 1984 — 2004.

Lately global albedo has seemed to be increasing, possibly due to regional aerosol issues.

If this change in global albedo is what is causing global warming, how did the process get started?

Moreover, epoch superposition analysis of Forbush decreases reveals no detectable albedo response to cosmic ray decreases, thereby placing an upper limit on the possible influence of cosmic ray variations on global albedo of 0.0029 per 5 % decrease.

Increased CO2 does not warm the atmosphere, it melts the snow and ice reducing global albedo, and that causes AGW.

Closed cloud cells tend to form over cool, upwelling zones increasing global albedo — open cloud cells form over warmer surfaces — decreasing planetary albedo (Koren et al 2017).

The melt of the Greenland glaciers is accelerating at an incredible rate and it can't be long before the Arctic sea ice disappears altering global albedo irrevocably.

Webster, The adjustment of ocean albedo is not the same for global albedo.

6) The main cloud bands move more poleward to regions where solar insolation is less intense and total global albedo declines via a reduction in global cloud cover due to shorter lines of air mass mixing.

How accurate is the earthshine method in determining global albedo?

16) The main cloud bands move more equatorward to regions where insolation is more intense and total global albedo increases once more due to longer lines of air mass mixing.

v) They even acknowledge that energy input to the oceans is affected but fail to link it explicitly to cloudiness and global albedo changes.

What you do not seem to be considering is that when the snow line rises the albedo will change, and since this ice retreat is global then the global albedo will be reduced leading to an increase in global mean temperature.

Recent research indicates that global albedo is fairly constant, and having no material effect on global temperatures.

The cosmic ray hypothesis is weakened further by observational evidence from satellites, as shown in another recent paper by Krissansen - Totton and Davies (2013) in Geophysical Research Letters, which also concludes that the there is no statistically significant correlations between cosmic rays and global albedo or globally averaged cloud height.

That means that global albedo has also been low and could explain global temperatures remaining high after last years El Nino.

I had the idea to put micronized CaCO3 on the surface of the oceans primarily to increase the global albedo of the Earth.

With respect to Mr. Best's post, which I may be unfairly implying is a good example, one of the fallacious but clever debate manipulations utilized by CC deniers and (way too many) lukewarmers is to focus relentlessly (often inaccurately) on climatological research frontiers such as climate sensitivity, or relations between evaporation, cloudiness, and global albedo.

That may be bad for Santa Clause and for polar bears, but if there is a large increase in the loss of sea ice then the global albedo will be affected, and inevitably the global climate will be affected too.

The mechanism by which the effect of oceanic variability over time is transferred to the atmosphere involves evaporation, conduction, convection, clouds and rainfall the significance of which has to date been almost entirely ignored due to the absence of the necessary data especially as regards the effect of cloudiness changes on global albedo and thus the amount of solar energy able to enter the oceans.

In the real world the most obvious and most common reason for an increase in the speed of energy flow through the system occurs naturally when the oceans are in warm surface mode and solar input to the oceans due to reduced global albedo is high as apparently occurred during the period 1975 to 1998.

ii) The oceans appear to vary in the rate at which they release solar energy back to the air which affects atmospheric composition via humidity, clouds and global albedo.

The researchers used a dataset of all global urban areas, called the Global Rural and Urban Mapping Project (GRUMP), to give a realistic estimate of the effects of a global albedo change.

Thus if the two mid latitude jets become more meridional and shift 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 any other proposed effects on global albedo from changes in cosmic ray intensity generating changes in cloud totals as per Svensmark.
