Rising anthropogenic, or human - caused, carbon dioxide in the atmosphere may have up to twice the impact on coastal estuaries as it does in the oceans because the human - caused CO2 lowers the ecosystem's ability to absorb natural fluctuations of the greenhouse gas, a new study suggests.

Oceans are taking in about 90 percent of the excess heat created by human greenhouse gas emissions, but they're also absorbing some of the carbon dioxide (CO2) itself.

All the greenhouse gases absorb infrared, and they also release the infrared, so these act as blockades to the infrared, leaving the atmosphere and going off into space; and the Earth warms up to send off even more infrared from the surface in order to reach its state, sort of a steady state with regard to space.

So the report notes that the current «pause» in new global average temperature records since 1998 — a year that saw the second strongest El Nino on record and shattered warming records — does not reflect the long - term trend and may be explained by the oceans absorbing the majority of the extra heat trapped by greenhouse gases as well as the cooling contributions of volcanic eruptions.

A: Global warming occurs when carbon dioxide (CO2) and other air pollutants and greenhouse gases collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth's surface.

These rising atmospheric greenhouse gas concentrations have led to an increase in global average temperatures of ~ 0.2 °C decade — 1, much of which has been absorbed by the oceans, whilst the oceanic uptake of atmospheric CO2 has led to major changes in surface ocean pH (Levitus et al., 2000, 2005; Feely et al., 2008; Hoegh - Guldberg and Bruno, 2010; Mora et al., 2013; Roemmich et al., 2015).

greenhouse gas A gas in Earth's atmosphere that absorbs and then re-radiates heat from the Earth and thereby raises global average temperatures.

Whether being lesser than CO2 in number of molecules in the atmosphere, methane is a potent greenhouse gas absorbing more infra - red radiation per molecule than CO2.

The ocean becomes less effective at absorbing carbon dioxide with a weakened AMOC and this can lead to higher quantities of the greenhouse gas in the atmosphere worsening global warming.

In 1861, John Tyndal published laboratory results identifying carbon dioxide as a greenhouse gas that absorbed heat rays (longwave radiation).

Greenhouse gases absorb and emit heat in the infrared spectrum.

Gases that trap heat in the atmosphere are called greenhouse gases, in large part because they absorb certain wavelengths of energy emitted by the EGases that trap heat in the atmosphere are called greenhouse gases, in large part because they absorb certain wavelengths of energy emitted by the Egases, in large part because they absorb certain wavelengths of energy emitted by the Earth.

The ocean stores much of the heat absorbed by the excess greenhouse gases in the atmosphere, so it could be beginning of that heat being unleashed back into the atmosphere.

The greenhouse gases absorb some infrared radiation emitted by the surface of the Earth and in turn radiate the absorbed energy back to the surface.

The Late Prof. Wangari Maathai and the Green Belt Movement recognized that green space reduces ambient heat in cities, mitigates the effects of pollution and absorbs greenhouse gases.

ABM: The whole point about the greenhouse gases in a planetary atmosphere is that they absorb the infrared radiation emitted by the surface, and so Kirchhoff's law does not apply.

Question 3: Third sentence: «Greenhouse gases re-radiate the absorbed energy in all directions, and thus part of this radiation goes back to the surface leads to warming.»

Greenhouse gases absorb intense emission from the surface and re-emit less intense energy at colder temperatures, resulting in an efficient heat trapping mechanism.

To repeat what I wrote in # 130, which you appear not to have absorbed: «All gases are greenhouse; they don't need to be able to absorb IR to heat — conduction & convection work perfectly well.»

Barton, For the atmosphere to be in thermodynamic equilibrium, the greenhouse gases must be emitting as much radiation as they absorb.

Increasing greenhouse gases means that more outgoing LWIR is absorbed and re-radiated and hence the atmosphere — and in the end the system represented by the Earth — warms.

It is important to note that the radiative loss from greenhouse gases is ONLY at frequencies that can be absorbed by near - by other near by greenhouse gases * and in all directions.

Words only have meaning in context and while it may be true that water vapor is a greenhouse gas in the sense that more of it in the atmosphere will absorb more infrared radiation and warm the climate, it is not a greenhouse gas in the sense that it is a gas we need to seriously worry about adding directly to the atmosphere.

A new paper in the Proceedings of the National Academy of Sciences, concluding that the buildup of human - generated greenhouse gases could leave a profound millenniums - long imprint on climate and sea levels, focuses on a characteristic of global warming that the public, and many policymakers, have not absorbed — at least according to John Sterman at M.I.T.

1) Greenhouse gasses absorb infrared radiation in the atmosphere and re-emit much of it back toward the surface, thus warming the planet (less heat escapes; Fourier, 1824).

Introducing a greenhouse gas that absorbs in the window regions would have a much larger effect than introducing a new greenhouse gas that absorbed where CO2 already did.

For example, using chemicals to make the planet more reflective might cool things a bit, but it would do nothing to reduce other greenhouse - gas impacts, like rising acidity in the oceans as they absorb more carbon dioxide.

CO2 is largely transparent to visual radiation but absorbs greatly in the infrared, i.e., it is a greenhouse gas.

1) Scientists have long known that greenhouse gases in the atmosphere — such as carbon dioxide, methane, or water vapor — absorb certain frequencies of infrared radiation and scatter them back toward the Earth.

Greenhouse gases such as CO2 cause a restriction in the flow of energy out from the Earth to space for reasons associated with the Quantum Mechanics of how these molecules absorb and radiate energy.

That's ironic that you mention that particular property of CO2, because there are scientist that theorize that, since CO2 is heavier, the GCM models are not correct — most CO2 produced at Earth's surface NEVER gets well mixed in fact most CO2 gets removed by rainfall, or gets absorbed by plants or the ocean long before it can cause any change in the so - called Greenhouse gas effect (but the GHG theory is not correct anyway) and the fact that they have severly underestimated CO2 upweelinng from the dee

Worse still, the clearing of the forests eliminates their ability to absorb carbon from the atmosphere, compounding the concentration of greenhouse gases in the atmosphere still more.

But most of the infra - red radiation emitted by the earth's surface is absorbed in the atmosphere by water vapour, carbon dioxide, and other naturally occurring «greenhouse gases», making it difficult for the surface to radiate energy directly to space.

*** I prefer to consider greenhouse gases and effectively lowering the surface albedo as, with a solid surface that doesn't evaporate in response to DWLIR the GHG causes the ground to absorb more energy than it otherwise would.
