The phrase
"atmospheric gases" refers to the different types of gases that make up Earth's atmosphere. These gases include oxygen, nitrogen, carbon dioxide, and other trace gases. They help create and maintain the air we breathe and are essential for sustaining life on Earth.
Full definition
The bubbles
of atmospheric gas trapped inside a sample can be analyzed to reveal information about past conditions and, by extension, past temperatures.
These ions result from the removal of electrons from
atmospheric gases by solar ultraviolet radiation.
Free oxygen is not bound to another element, as are the oxygen atoms in
other atmospheric gases like carbon dioxide and sulfur dioxide.
The reason for scientific concern over global warming rests on basic physics — infrared absorption — and robust measurements of
atmospheric gas concentrations.
The long - term global warming trend is predominantly a forced climate change caused by increased human -
made atmospheric gases, mainly CO2 [1].
If so, please explain what is wrong with our knowledge of quantum mechanics and the properties
of atmospheric gases.
It is unlike all
other atmospheric gases because it varies naturally from almost zero in desert regions to 4 percent in the tropics.
The long - term global warming trend is predominantly a forced climate change caused by increased human -
made atmospheric gases, mainly CO2 [1].

Absorbing atmospheric gases Greenhouse gases: water vapor, carbon dioxide, methane, and some nitrogen oxide pollutants a. transmit visible light, but absorb infrared light.
For these experiments, the researchers exposed grass plants in specially designed continuously stirred tank reactor chambers that allow researchers to expose plants to
different atmospheric gas concentrations.
17 Unnatural Climate Changes Greenhouse effect: the natural heating of Earth's surface caused by
certain atmospheric gasses called greenhouse gasses.
More research is needed to see if this novel use of
atmospheric gases as an alternative energy source is more widespread in Antarctica and elsewhere, the scientists say.
«It is possible that an increase in concentration of
atmospheric gases which absorb the outgoing infrared radiation could result in a rise in average global temperature,» William McCollam, Jr., then president of EEI, admitted to Congress in 1989.
Change of surface temperature between 1990 and 2090, as predicted by the Geophysical Fluid Dynamics Laboratory (GFDL) GCM forced by the anticipated change in
atmospheric gas composition.
However, efforts to slow emissions of the principal
atmospheric gas driving climate change, CO2, have been ineffectual so far (Fig. 1).
In the experiment, cosmic radiation was passed through a large reaction chamber containing a mixture of lower
atmospheric gases at realistic concentrations that was exposed to ultraviolet radiation from lamps that mimic the action of the sun's rays.
Today Earth is out of balance because increasing
atmospheric gases such as CO2 reduce Earth's heat radiation to space, thus causing an energy imbalance, as there is less energy going out than coming in.
If the cloud were dense enough, hydrogen atoms might flow into the atmosphere and react with oxygen, depleting our
vital atmospheric gases.
«This new understanding about how life can still exist in physically extreme and nutrient - starved environments like Antarctica opens up the possibility of
atmospheric gases supporting life on other planets,» says Associate Professor Ferrari.
However, efforts to slow emissions of the
principal atmospheric gas driving climate change, CO2, have been ineffectual so far (Fig. 1).
Today Earth is out of balance because
increasing atmospheric gases such as CO2 reduce Earth's heat radiation to space, thus causing an energy imbalance, as there is less energy going out than coming in.
At these high altitudes, the
residual atmospheric gases do in fact become sorted into strata according to molecular mass, as de Bort had earlier conjectured for the stratosphere.»
For the last 10,000 years or so, carbon dioxide levels in the atmosphere remained more or less the same: plants photosynthesised tissues from atmospheric carbon, oceans
dissolved atmospheric gases, rocks reacted with the atmosphere to form mineral carbonates, herbivores consumed plants, man and other carnivores devoured grazing animals, but the overall ratio of the greenhouse gas carbon dioxide remained the same.
Newer volcanic rock on Venus tends to emit more infrared,
because atmospheric gases weather older rocks and change their composition (Science, DOI: 10.1126 / science.1186785).
The discovery opens up the tantalizing possibility that on other planets, life forms that need
only atmospheric gas to survive exist, too.
The very fact that I am breathing is a testament to the adaptability of life to mutate over time and incorporate
available atmospheric gasses as a means of furthering its own functioning.
If the planet was hotter or colder or had a different make up of
atmospheric gases then we, along with the rest of life on Earth, woudl have evolved differently.
«Minerals from Papua New Guinea hold secret for recycling of noble gases: Scientists
find atmospheric gases trapped in minerals that are crystallized in Earth's mantle.»
