Greenhouse gases slow down the rate of heat - loss from the surface of the Earth, like a blanket that slows down the rate at which your body loses heat.

If we now add water vapor and / or CO2 to the air then temperature of the air layer will become Ta» > Ta due to the absorption of a part of the upward radiation by vapor and / or CO2, which will reduce the heat losses from the surface to the layer since we now have h * (T - Ta»).

It would be more clarifying to present two diagrams one for the daytime and one for the nighttime when there are effective heat losses from the surface into the air layer above.

If on the other hand you mean that the GHGs act like insulation which slows the heat loss from the surface, I would have to think about that, but can't at this point disagree that it is possible.

«what does happen is that the water surface radiates away at about 400W / m ^ 2, in fact the top few microns will be cooler than the water a mm deeper because the transfer of heat from lower down (conduction, convection, diffusion etc.) is slower than the loss from the surface.»

In making that latter statement, I am not excluding that the general temperature of the atmoshere (whatever that may be) does not slow down the heat loss from the surface or affect the height at which energy is radiated into space.

It seems to me that so far, having determined that radiative energy can slow the heat loss from the surface, the questions which remain unresolved are:

Not exact matches

The loss was largely due to a $ 916 million impairment charge on its long - lived assets, stemming both from a major tax and export dispute between its 64 - per - cent owned Acacia Mining and the Tanzanian government, and the partial writedown of its Pascua Lama project after the Chilean government ordered it to close all surface facilities.

The additional dimension can, somewhat simplistically, be thought to provide the vantage point of perspective from which the surface may be defined without loss of detail.

Water loss increases as temperatures rise because plants use more water, and higher temperatures increase evaporative loss from the soil and from the water surface and lengthen the growing season.

They found that selective logging and surface wildfires can result in an annual loss of 54 billion tonnes of carbon from the Brazilian Amazon, increasing greenhouse gas emissions.

The drought that is devastating California and much of the West has dried the region so much that 240 gigatons worth of surface and groundwater have been lost, roughly the equivalent to a 3.9 - inch layer of water over the entire West, or the annual loss of mass from the Greenland Ice Sheet, according to the study.

While the typical way of measuring erosion is to calculate volumetric loss, using data from satellites to obtain measurements of the dune's three - dimensional surface area before and after an event, that data is expensive and therefore often unavailable unless a storm is exceptionally devastating, like Sandy.

So without air resistance and other energy losses from friction, a wheel rolling along a flat surface will keep on trucking forever.

But, special vessels circulate blood away from these surfaces to keep heat loss to a minimum.

By 1900, increased emissions of soot could have triggered the loss of more than 15 m of ice from a glacier's surface; by 1930, the loss could have totaled 30 m or more — magnitudes and timing that can easily account for the Alpine glacial retreat, the scientists contend.

Complementary analyses of the surface mass balance of Greenland (Tedesco et al, 2011) also show that 2010 was a record year for melt area extent... Extrapolating these melt rates forward to 2050, «the cumulative loss could raise sea level by 15 cm by 2050 ″ for a total of 32 cm (adding in 8 cm from glacial ice caps and 9 cm from thermal expansion)- a number very close to the best estimate of Vermeer & Rahmstorf (2009), derived by linking the observed rate of sea level rise to the observed warming.

All of this is compounded by the fact that trees close their stomata (surface pores that control gas exchange) when facing drought to prevent water loss from transpiration, but this can collapse the hydraulic transport system.

When comparing between four size classes, two microplastic < 4.75 mm and meso - and macroplastic > 4.75 mm, a tremendous loss of microplastics is observed from the sea surface compared to expected rates of fragmentation, suggesting there are mechanisms at play that remove < 4.75 mm plastic particles from the ocean surface.

Because the loss of CO2 from the atmosphere is temperature sensitive (higher temperature leads to more rain and more carbonate formation) but the source of the CO2 is temperature insensitive (volcanoes do not care about the surface temperatures), the whole cycle forms a net negative feedback cycle: higher temperatures will result in cooling and lower temperatures will result in warming.

The team also compared the ice loss up until the mid-1980s to that observed by satellites over roughly the last decade and found that today the rate of ice loss is twice the 20th century average, mostly because of increased water runoff from the ice sheet's surface.

The thermal gradient through this layer dictates the rate of heat loss from the (typically) warmer ocean surface, to the cooler atmosphere above.

When the tip of the microscope oscillates over certain surfaces, in this case over NbSe2 (niobium selenide), peaks of «dissipation» (i.e., loss of energy) can be seen when the tip is at specific distances from the surface, as if it were held back, at certain locations, by some frictional force.

In addition, reductions in calcification from lowered pH in surface waters could reduce phytoplankton sinking rates through loss of ballast (Hofmann and Schellnhuber, 2009), though this effect will depend on the ratio of the fraction of ballasted vs. un-ballasted fractions of the sinking POC.

One year without a net loss also doesn't buck the long - term trend of Greenland losing ice, both from surface melt and from ocean waters eating away at glaciers that flow out to sea.

With multiple layers of paint, color and line, she creates an ambiguous space that affords the viewer an intimacy with her subject matter and both obscures and recalls the pain it evokes («Pietà») In her catalogue essay, Tina Kinsella writes, «Bracha's recent paintings beckon us to reprise the work of mourning, to return to the grounds from which the act of lamentation arrives and to reappraise the particular emotion that the laboring through grief produces... the Pietà always threatens to disclose this excess of sorrow by surfacing the penumbra of future loss that lurks in the heart of the maternal relationship between mother and child.»

And what is so remarkable is that the very loss at its core — a portrait is a person here, but not here — is countered by the slow lyricism of the work: Gorky's mother is brought back from annihilation, held in the bounding contours and gentle colour, her momentary image indelibly fused with the painting's hard - won surface.

And the series, which went on show earlier this year at the Pg Gallery in Istanbul, Turkey, poses a question: just as an iceberg hides 91 per cent of its mass below the surface, how much do we hide away from our sense of loss at leaving home?
