absorb greenhouse gases from the atmosphere, researchers announced Thursday.

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.
Currently, the amount of infrared heat radiated back to space is slightly less than what we
absorb from the sun due to the increase in
greenhouse gases.

It's not totally about how much infrared
from the surface that is blocked (currently about 90 % of surface emissions is

absorb and re-radiate infra - red (IR) radiation that is emitted
from the planet's surface at rates that depend on the temperature (the Stefan - Boltzmann law).
If one could see the IR light, an opaque atmosphere would make the pattern of emitted IR diffuse since only the IR
from the upper levels of the atmosphere escape to space after it has been
absorbed and re-emitted by the
greenhouse gases (this of course depends on the wavelength of the IR and the absorption spectrum, but we can use this assumption for heat loss integrated over the whole IR spectrum).

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

With adequate training they would be aware of the science that all of the radiant heat
from the earthâ $ ™ s surface that is going to be
absorbed by
greenhouse gases gets
absorbed close to the ground (half within less than 24 meters) and is carried up by convection currents to where it ultimately gets radiated to space.
The heat caused by infrared radiation is
absorbed by
greenhouse gases such as water vapor, carbon dioxide, ozone and methane, which slows its escape
from the atmosphere.
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.»
You are exactly right — that is what Miskolczi
greenhouse theory (MGT) actually predicts.Miskolczi theory differs
from Arrhenius in that it can handle more than one
greenhouse gas simuultaneously
absorbing in the infrared.
Additionally the researchers note that the drought frequency paired with longer recovery time could lead to tree death and thus a lowered ability of the region to
absorb carbon
from the atmosphere, further increasing
greenhouse gasses in the atmosphere.
It differs
from the Arrhenius theory in being able to handle more than one
greenhouse gas simultaneously
absorbing in the infrared.
Absorbing CO2
from the atmosphere is another way oceans mitigate
greenhouse gas impacts, although marine waters are growing increasingly acidic as a result.
So, for example, the Sun's effects on the recent «global warming» are said to be of no significance, that it's all due to the
greenhouse gas increase
absorbing and radiating back / holding in blanket, the infrared heat upwelling
from the surface.
Another way is
from certain wavelengths of the light that are reflected back and get
absorbed by
greenhouse gases and warm the atmosphere (mostly water vapor, methane and tiny amounts of CO2).

This makes them better at
absorbing energy
from infrared radiation... which is why they are such effective
greenhouse gases.

absorbing nearly 1 W / m2 more energy
from the Sun than it is emitting to space, portending further warming even if
greenhouse gas levels were immediately stabilized.
Traditional anthropogenic theory of currently observed global warming states that release of carbon dioxide into atmosphere (partially as a result of utilization of fossil fuels) leads to an increase in atmospheric temperature because the molecules of CO2 (and other
greenhouse gases)
absorb the infrared radiation
from the Earth's surface.
Greenhouse gases «trap» radiative energy because they

from the Earth's surface which then continually «bounces up and down».

Here's Merriam Webster's version: Main Entry: carbon dioxide Function: noun: a heavy colorless
gas CO 2 that does not support combustion, dissolves in water to form carbonic acid, is formed especially in animal respiration and in the decay or combustion of animal and vegetable matter, is
absorbed from the air by plants in photosynthesis, and is used in the carbonation of beverages I know you'll all correct me if i'm wrong in stating if CO2 has no scientific facts supporting global warming based upon a factor of
greenhouse gases (as opposed to solar radiation in another post, which would be defined by variations in earth, space, or similar factors), then where does science determine that CO2 «disolves in water to form carbonic acid» and is «
absorbed from the air by plants in photosythesis»?

from escaping into space, but also by
absorbing more outgoing energy, leading to warmer surface temperatures.

-LSB-...] The study, led by Professor Chris Reid,
from the Sir Alister Hardy Foundation for Ocean Science (SAHFOS), the University of Plymouth and the Marine Biological Association (MBA), has found that both rising sea temperatures and a reducing ability of the oceans to
absorb the
greenhouse gas carbon dioxide (CO2) may be leading to an acceleration of climate change.

absorbing more energy
from sunlight than it emits back to space, providing perhaps the strongest evidence to date that rising concentrations of
greenhouse gases and other pollutants are the primary cause of the current global warming trend.

greenhouse gas, which means it allows visible light
from the Sun to pass through the atmosphere while

greenhouse gases escaping
from trees, plants and soils — which have traditionally buffered the warming by
absorbing the
gases.
