Sentences with phrase «consider albedo change»

Not exact matches

A diminishing albedo in Arctic sea ice can be considered both the cause and effect of changes in sea ice.
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.
I guess I am surprised that with better understanding of the importance of water vapor feedback, sulfate aerosols, black carbon aerosols, more rapid than expected declines in sea ice and attendant decreases in albedo, effects of the deposition of soot and dust on snow and ice decreasing albedo, and a recognition of the importance of GHGs that were probably not considered 30 years ago, that the sensitivity has changed so little over time.
That's pretty alarming, especially when considered in the context of other positive feedbacks including changes in albedo from melting icecaps and release of carbon and methane from thawing permafrost.
The model considers all relevant feedback processes caused by changes of water vapour, lapse - rate, surface albedo or convection and evaporation.
I guess I am surprised that with better understanding of the importance of water vapor feedback, sulfate aerosols, black carbon aerosols, more rapid than expected declines in sea ice and attendant decreases in albedo, effects of the deposition of soot and dust on snow and ice decreasing albedo, and a recognition of the importance of GHGs that were probably not considered 30 years ago, that the sensitivity has changed so little over time.
Dr Curry, When considering changes in albedo due to melting, pools, etc, is there also consideration that the Sun is very low in the sky and much of the incoming Solar is reflected off water as glare?
Once you've solve that, you could consider how it would change if the albedo were about 0.12 (the Moon) and how it would change if the 1 square metre patch were at a different latitude.
Just because you can not measure it, or do not have the time to consider all of the changes in the sun and how it affects the planet's albedo, does not mean it is not there.
That's a pretty silly claim on Dr. Curry's part if you consider that in the months the arctic sea ice isn't diminished, there's never really so much sunlight as you'd count it against the average, so whatever albedo changes there are during the half of the year that matters, they're when the sun is at its highest angle.
Consider the hemispherical distribution of land vs water to gain a sense of the size of the mismatch (and the subsequent relative changes in albedo between glaciation and interglacial).
