Once heated, the ocean surface becomes
warmer than the atmosphere above, and because of this heat flows from the warm ocean to the cool atmosphere above.
Now, this process can only take place if the ocean is

warmer than the atmosphere, so the heat can't come back up.
Have no idea who the «climate clique» is, but the greater energy storage capacity and greater thermal inertia of the oceans combined with the fact that net heat flow is always from oceans to atmosphere would dictate that the oceans would show more consistent long - term
warming than the atmosphere.
I think you agree though that that is not happening, the oceans on average being
warmer than the atmosphere.
One example I like was a relatively recent explanation of why the Earth was warming and why the temperatures in winter were lower than average; the reason was apparently that an ocean
warmer than the atmosphere above was taking heat out of the atmosphere resulting in cooler winter temperatures.
During the night when the sun does not shine, the earth surface is perhaps ten degrees
warmer than the atmosphere.
On average they are about 1 or 2 degrees
warmer than the atmosphere, so on average they transfer heat to the atmosphere, but this happens only at the surface so heat that has migrated below 700 meters, often considered the deep ocean, is essentially out thermal communication with the atmosphere as if had been sent into space.
* The ground is a little
warmer than the atmosphere, so that factor will mean some more photons going up than down (but since the back radiation is mostly from low layers, the atmosphere emitting the back radiation will not be that much cooler than the land so the effect from temperature will not be TOO great) * The ground is close to a black body for IR (emissivity = 1 for all IR frequencies), but the atmosphere has bands where it does not emit or absorb well (emissivity ~ 0) and other bands where it does emit or absorb well (emissivity ~ 1).

During the Eocene, the concentration of carbon dioxide in the
atmosphere was more
than 560 parts per million, at least twice preindustrial levels, and the epoch kicked off with a global average temperature more
than 8 degrees Celsius — about 14 degrees Fahrenheit —
warmer than today, gradually cooling over the next 22 million years.
«Although most of the macrophyte carbon is released back to the
atmosphere in the same form that it is assimilated, carbon dioxide, some of it is actually exported to the ocean as dissolved carbon or released to the
atmosphere as methane, a gas that has a
warming potential 20 times larger
than carbon dioxide,» said John Melack, a professor at the University of California, Santa Barbara.
But when unburned methane is released into the
atmosphere, it is a potent greenhouse gas with a
warming potential 28 to 34 times greater
than carbon dioxide over a 100 - year timeframe (and up to 84 times more potent over a 20 year timeframe).
Whiter colors represent
warmer temperatures, showing that the odd structure is hotter
than other areas of the
atmosphere.
Methane is an extremely efficient greenhouse gas which may contribute to enhanced global
warming when free in the
atmosphere, and such free methane, would then be considered a pollutant rather
than a useful energy resource.
«However, it is also slightly larger
than the Earth, and so the hope would be that this would result in a thicker
atmosphere that would provide extra insulation» and make the surface
warm enough to keep water liquid.
But for planetary scientists, Jupiter's most distinctive mystery may be what's called the «energy crisis» of its upper

«For the most part I agree with the [Intergovernmental Panel on Climate Change], that adding CO2 to the

warm temperatures.
The rate at which carbon emissions
warmed Earth's climate almost 56 million years ago resembles modern, human - caused global

That's greater
than the
warming rate of either the ocean or the
atmosphere, and it can have profound effects, the scientists say.
Short - lived climate pollutants are so called because even though they
warm the planet more efficiently
than carbon dioxide, they only remain in the
atmosphere for a period of weeks to roughly a decade whereas carbon dioxide molecules remain in the

The last time researchers believe the carbon dioxide concentration in the

Pielke, who said one issue ignored in the paper is that land surface temperature measurements over time show bigger
warming trends
than measurements from higher up in a part of the
atmosphere called the lower troposphere, and that still needs more explanation.

Already, the planet's average temperature has
warmed by 0.7 degree C, which is «very likely» (greater

than carbon dioxide at trapping heat in the

Its mixing ratio in the

than that of CO2 (about 4 parts per trillion ppt in 1990 versus 365 ppm of carbon dioxide), its contribution to global

The next step was see how those factors were influenced by ENSO; while El Niños and La Niñas are defined by how much
warmer or colder
than normal tropical Pacific ocean waters are, they trigger a cascade of reactions in the
atmosphere that can alter weather patterns around the globe.
«It is true that they do
warm climate by strong methane emissions when they first form, but on a longer - term scale, they switch to become climate coolers because they ultimately soak up more carbon from the
atmosphere than they ever release.»
This year has already brought higher temperatures
than normal nation - wide, and that trend is expected to continue, in part due to global

«For every ton of CO2 emitted [into] the
atmosphere, the natural sinks are removing less carbon
than before,» says biologist Josep «Pep» Canadell, executive director of the Global Carbon Project — an Australia — based research consortium devoted to analyzing the pollution behind global

According to the accepted view, the formation of the Earth released vast amounts of water vapour and carbon dioxide, which formed a thick
atmosphere and caused strong greenhouse
warming at a time when the Sun was 15 to 20 per cent fainter
than today.
One thing is already clear: A
warmer global
atmosphere currently holds about 3 to 5 percent more water vapor
than it did at the beginning of the 20th century, and that can contribute to heavier precipitation.
