greenhouse gas emissions.
Rising anthropogenic, or human - caused, carbon dioxide
in the atmosphere may have up to twice the impact on coastal estuaries as it does

absorbed by the world's tropical forests and the amounts of
greenhouse gas emissions created by loss of trees, as a result of human activity.
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.

in greenhouse gas emissions is simply because those croplands are already
absorbing large quantities of carbon.
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.

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).

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

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.

in the lowest few kilometres of the atmosphere, the troposphere.
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 the Arctic, the tipping points identified in the new report, published on Friday, include: growth in vegetation on tundra, which replaces reflective snow and ice with darker vegetation, thus absorbing more heat; higher releases of methane, a potent greenhouse gas, from the tundra as it warms; shifts in snow distribution that warm the ocean, resulting in altered climate patterns as far away as Asia, where the monsoon could be effected; and the collapse of some key Arctic fisheries, with knock - on effects on ocean ecosystems around the globe.&raqu
