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.

Not exact matches

They tend to believe that as the planet warms, low - level cloud cover will increase, thus increasing planetary albedo (overall reflectiveness of the Earth), offsetting the increased greenhouse effect and preventing a dangerous level of global warming from occurring.

al find that the spread in 2xCO2 climate sensitivity among CMIP GCM's is largely due to differences in low cloud behavior, and that's primarily an albedo effect.

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??

In fact, if the physics - based understanding of «equilibrium sensitivity» to any forcing is too low, then not only will CO2 have a greater effect, so too will all other forcings, such as: changes in the sun, in cloud cover, in albedo, etc..

UHI / Land use will manifest itself as two effects: 1 Lower albedo.

This is germane to a recent paper by Rosing et al (2010) which purported to show that the «faint sun» paradox can be resolved through a lower albedo rather than through a substantially enhanced greenhouse effect.

This being the case, a period of higher sunspot activity would likely lead to reduced lower tropospheric cloud cover (due to reduced albedo effect) and generally higher temperatures.

The cryosphere derives its importance to the climate system from a variety of effects, including its high reflectivity (albedo) for solar radiation, its low thermal conductivity, its large thermal inertia, its potential for affecting ocean circulation (through exchange of freshwater and heat) and atmospheric circulation (through topographic changes), its large potential for affecting sea level (through growth and melt of land ice), and its potential for affecting greenhouse gases (through changes in permafrost)(Chapter 4).

This being the case, a period of higher sunspot activity would likely lead to reduced lower tropospheric cloud cover (due to reduced albedo effect) and temperatures.

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

The albedo lows are punctuated by the brightening effect of snowfall events.

CERES apparently can distinguish between high and low level clouds based on their published images, but the overall albedo figure won't show a cosmic effect as strongly.

Greenhouse gas clouds lower the Albedo of the Earth resulting in a lower effective emission temperature — you shouldn't count the greenhouse effect of clouds and then not count the solar reflecting impact of the same clouds.

Despite the head - start in temps, lower albedo and amplifying effects of much higher humidity, jungle highs fall short of desert high temps.

(Note, however, that to the extent that positive cloud feedbacks on GHG - mediated forcing mediate a reduction in cloud cover, the amplification will substitute some SW effects for LW effects due to the reduced cloud greenhouse warming and increased warming from a lower albedo).

So, CO2 - AGW is probably very low [overestimated by a factor of > = c. 3] and «cloud albedo effect» heating has probably been responsible for the warming, now stopped because the effect has has saturated.

Had they applied reasonable physical models for the integrating and lagging (low pass filtering) response of the ocean, and the positive feedback of cloud albedo from the burn off effect, they could have discovered that solar activity can account for the full, 140 - year instrumented temperature record.

At low humidity the albedo impact is less than the greenhouse effect, so net warming.

Atmospheric aerosol science is pretty thin, including their role in low - level (warming) and high - level (cooling) cloud development, PM agglomeration, PM and VOC oxidation, condensation and precipitation effecting albedo.

Antarctic sea ice, being at a generally lower latitude than Arctic sea ice, has more profound effect on ocean energy budget via albedo i.e. we should worry more about declines in Antarctic sea ice than Arctic.

Therefore, the effect of warming in the arctic is cooling at the lower latitudes, from increased albedo from clouds and snow, and transportation of colder air from the arctic.

David Springer wrote: The greenhouse effect, by trapping infrared radiation, can lower the albedo of the earth and cause global warming.

2) We have INCREASING POSITIVE feedback effects from (a) melting tundra, (b) melting melting hydrates in the oceans, (c) lower reflectivity (albedo) of the Arctic itself, not to mention its next door neighbor Greenland, (d) increased fires in northern Asia and North America which will further exacerbate albedo, (e) LESS ICE AREA to reflect sun in the Arctic... and thus allow that nice dark water to absorb more and more sun.

If the low altitude cloud cover increased by only 1 % per degree of warming, this would represent -0.48 W / m ^ 2K, more than canceling out the ice - albedo effect (for comparison, Spencer et al. measured — 6.1 W / m ^ 2K or over ten times this impact)..

While the second option, also called albedo modification, is relatively inexpensive and could quickly lower the planet's temperature, it could have unwanted effects on the Earth's weather pattern, which could potentially bring drought to some regions or be used as a weapon by governments or certain individuals.
