Sentences with phrase «albedo effect»

And by knocking down trees, which absorb sunlight, a mammoth could cause more sun to be reflected, increasing the cooling albedo effect on the permafrost.

Actually more the opposite (if their analysis were correct) since the clouds under consideration have a higher greenhouse effect associated with them, not a higher albedo effect.

Interesting, now you believe in the positive albedo effect.

It's almost guaranteed that you've experienced that albedo effect personally at some point in your life.

Thus the BC - snow albedo effect contributes to warming.

• We do not need to differ between low & high clouds, only their total albedo effect matters.

For example, AR4 WG1 assesses the level of scientific understanding of cloud albedo effects as «low.»

The Adirondacks are within the temperate forest system, where albedo effect is not as strong as in boreal system — but still a complicating variable.

Unger says it won't work, pointing to an old argument about the offsetting effects of carbon release and the increase of energy reflection when forests are removed — the so - called albedo effect.

This positive feedback phenomenon, called the runaway albedo effect, would eventually lead to a single dominating ice cap, like the one observed on Pluto.

But much stronger albedo effects (a measure of how much sunlight is simply reflected back out into space) might be generated by the high winds of the glacial era, giving 10 °C temperature changes rather than the 1 °C excursion of the Little Ice Age.

These are the first order effects, where a second order effect is that cloud cover eclipses or reveals surface albedo, so a net albedo effect is important.

I wanted to ask a question very similar to one already asked by Alastair in # 12: Is anyone looking at what the affect on GIS might be of a warm Arctic sea due to albedo effects once the sea ice is gone in the summer?

Ex: Albedo Effect Albedo - reflectivity of a surface Ice reflects heat.

Presumably they have little to no shortwave albedo effect, but how significant is the downwelling infrared term (it's very dry) at either ice sheet during the dark months?

The slides also show some interesting albedo effects.

Aggregates that defy locally your primer version of physics and in so doing create albedo effects lowering temperature, precipitation events lowering sea level when over land and altering temperature left right and centre.

And we don't have to go back all that far to get changes in carbon dioxide in the atmosphere and quite unknowable albedo effects.

For truly boreal systems (further north than Adirondacks), my understanding is that there is enough evidence for a strong warming albedo effect of forests (counter-acting the cooling effect of C sequestration) that we probably should not attribute carbon offsets to boreal reforestation based simply on carbon accounting of tree biomass.

The ice - albedo effect leaps to mind.

To make matters worse, the earlier loss of snow in the region could trigger the dreaded albedo effect — basically a positive feedback loop in which melting snow exposes the ground, leading to more heat being absorbed and, eventually, more warming.

So we are left with a relatively small delta in the ice albedo effect over the northern summer months with an even smaller delta in the other direction during the southern summer months (when albedo plays a role).

Called the runaway albedo effect, this phenomenon would eventually lead to a single dominating ice cap, like the one observed on Pluto's heart.

Which is the higher albedo effect I wonder.

nednead, I'm not sure who the «you» is in «now you believe in the positive albedo effect.»

When diagnosed within a GCM framework, the semi-direct effect can also include cloud changes due to circulation effects and / or surface albedo effects.
