Sentences with phrase «change the albedo factor»

For example, the upper portions of most clouds are predominantly ice crystals that change the albedo factor considerably.

Not exact matches

These factors have decreased the region's albedo, or the fraction of incoming light that Earth reflects back into space — a change that the CERES instruments are able to measure.

For one thing, the fit neglects lags in the system (such as those resulting from ocean heat uptake) and it also neglects changes in albedo and other radiative factors.

Other factors would include: — albedo shifts (both from ice > water, and from increased biological activity, and from edge melt revealing more land, and from more old dust coming to the surface...); — direct effect of CO2 on ice (the former weakens the latter); — increasing, and increasingly warm, rain fall on ice; — «stuck» weather systems bringing more and more warm tropical air ever further toward the poles; — melting of sea ice shelf increasing mobility of glaciers; — sea water getting under parts of the ice sheets where the base is below sea level; — melt water lubricating the ice sheet base; — changes in ocean currents -LRB-?)

All it demonstrates is that there is more than one causal factor, as is well known, with aerosols (from fossil fuels and volcanoes), land - use changes (through affecting CH$ and CO2 levels and albedo) and solar irradiance all playing a role.

As an analogy, if I told you that I was going to paint my white car black and that I expected it would get hotter on sunny days as a result, you would probably start asking questions about what the temperature of the paint was when I applied it and how those molecules heated up or cooled down, ignoring the relevant factor which is this: By painting the car black, I am changing the car's albedo and thus changing the radiative balance between the car and the sun on sunny days.

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.

It is not that the polar regions are amplifying the warming «going on» at lower latitudes, it is that any warming going on AT THE POLES is amplified through inherent positive feedback processes AT THE POLES, and specifically this is primarily the ice - albedo positive feedback process whereby more open water leads to more warming leads to more open water, etc. *** «Climate model simulations have shown that ice albedo feedbacks associated with variations in snow and sea - ice coverage are a key factor in positive feedback mechanisms which amplify climate change at high northern latitudes...»

Increasing CO2 does increase the greenhouse effect, but there are other factors which determine climate, including solar irradiance, volcanism, albedo, orbital variations, continental drift, mountain building, variations in sea currents, changes in greenhouse gases, even cometary impacts.

«Climate model simulations have shown that ice albedo feedbacks associated with variations in snow and sea - ice coverage are a key factor in positive feedback mechanisms which amplify climate change at high northern latitudes...»

The model accounts for convection and radiation, thermal inertia and changes in albedo (ρ) and greenhouse factor (γ).

E.g., human - caused albedo variations from desertification, and to some extent tropical deforestation, were connected with past global climate changes by Sagan et al. (1979); a pioneering model confirming «the long - held idea that the surface vegetation... is an important factor in the Earth's climate» was Shukla and Mintz (1982); Amazon Basin: Salati and Vose (1984); more recently, see Kutzbach et al. (1996).

So now there only remains for you to factor in the time lagged responses of isostatic adjustments, albedo feedback, ice melt and ocean heat accumulation to rapid forcing changes.

The Arctic provides an early indicator of global climate change through feedback systems associated with factors such as the high albedo of snow and ice [Holland and Bitz, 2003].

Given that the blackbody equilibrium temperature of earth as seen from space is a function of solar irradiance arriving and earth albedo and not much of anything else apart from factors that change those two, anyone claiming earth's temperature isn't affected by solar output better have a pretty good theory and data to support that.

There are other factors such as albedo change, buildings that diminish surface winds, and anthropogenic heat sources from anthing that consumes fuel or electricity to produce work and waste heat which buildings then help to trap.

He takes climate change to be the norm of things and he accepts that humans are influencing climate through many factors and not just through emissions (e.g. how we change the albedo, the reflectivity, of the Earth's surface).

There are for example biogenic factors reacting to changes in temperature that can not be ignored, affecting surface albedo, ozone levels and cloud formation.

«climate scientists have long taken into account many other factors that can influence the climate, and which can change, such as ocean - atmopshere oscillations, the albedo of advancing and retreating glaciers, changing levels of incoming radiation»

In other words albedo is not just a fudge factor in the climate models but rather a damn big fudge factor that dwarfs any change that anthropogenic CO2 can possibly bring about.
