Sentences with phrase «absorbed out of the atmosphere»

Not exact matches

One approach that is gaining currency among environmental scientists is carbon dioxide capture and storage (CCS), a form of carbon sequestration in which CO2 is removed from the waste gas of power plants, typically by absorbing it in a liquid, and subsequently burying it deep underground, hence keeping the gas out of the atmosphere.

As the eons passed, most of the carbon dioxide was absorbed into carbonate rocks, and Earth's atmosphere, which started out 10 to 20 times as thick as it is today, gradually thinned.

Whether they are absorbing or releasing the gas, they will always be keeping some CO2 out of the atmosphere and providing other ecological benefits.

For example, molecules in a planet's atmosphere will absorb a certain amount of energy from starlight and radiate the rest back out.

Forests and other land vegetation currently remove up to 30 percent of human carbon dioxide emissions from the atmosphere during photosynthesis, but thanks to this latest study, experts now know that we have tropical forests to thank for a great deal of this work - absorbing a whopping 1.4 billion metric tons of CO2 out of a total total global absorption of 2.5 billion metric tons.

[1] CO2 absorbs IR, is the main GHG, human emissions are increasing its concentration in the atmosphere, raising temperatures globally; the second GHG, water vapor, exists in equilibrium with water / ice, would precipitate out if not for the CO2, so acts as a feedback; since the oceans cover so much of the planet, water is a large positive feedback; melting snow and ice as the atmosphere warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar warming than the global average; decreasing the temperature gradient from the equator to the poles is reducing the driving forces for the jetstream; the jetstream's meanders are increasing in amplitude and slowing, just like the lower Missippi River where its driving gradient decreases; the larger slower meanders increase the amplitude and duration of blocking highs, increasing drought and extreme temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (driving up prices for disk drives — hows that for unexpected adverse impacts from AGW?)

Since anthropogenic emitted CO2 comes out of a power plant stacks / vehicle exhausts at an elevated temperature (due to the trivial manmade waste heat energy), and then cools down to near equilibrium with the rest of the atmosphere, why would this new CO2 then absorb more energy and heatup again?

CO2 (and some other gases) in the atmosphere are however more opaque to LWIR; they absorb that a chunk of that outgoing radiation and re-radiate it in all directions — so that a fraction less than half is re-radiated downwards; which has the effect of slowing the transfer of heat (by radiation) out of the atmosphere.

It is the plants on the planet that absorb carbon dioxide, so it is between forests and the rest of the productive landscape to take carbon out of the atmosphere.

Globally, the Ozzies have pointed out that the oceans have been busy absorbing almost all of the heat energy (90 %) The atmosphere and the land, including ice, store the other 10 %.

CO2 traps heat According to radiative physics and decades of laboratory measurements, increased CO2 in the atmosphere is expected / predicted to absorb more infrared radiation as it escapes back out to space.

We can take carbon out of the atmosphere, through biofuels, or by using solar / nuclear heat to turn CaCO3 into CaO and a pure stream of CO2 (to be sequestered), subsequently allowing the CaO to absorb CO2 from the air and so forth.

If CO2 and H2O molecules now are cooled below the previous equilibrium point by having their radiation allowed to escape to outer space, then I believe these molecules must then tend to absorb more energy than yield energy with each interaction with the other components of the atmosphere until that atmosphere as a whole reaches a new thermal equilibrium where the net radiation going out and the net radiation coming in (primarily from the sun and the surrounding atmosphere) is the same.

«The fact that the earth's atmosphere can not safely absorb the amount of carbon we are pumping into it is a symptom of a much larger crisis, one born of the central fiction on which our economic model is based: that nature is limitless, that we will always be able to find more of what we need, and that if something runs out it can be seamlessly replaced by another resource that we can endlessly extract.»

As part of the Earth's natural carbon cycle, vast amounts of carbon dioxide are taken out of the atmosphere and absorbed by the land each year.

Coastal marshes absorb and store large amounts of carbon dioxide from Earth's atmosphere; they help filter out pollution in coastal waters; provide habitat for wildlife; help protect coastlines from erosion and storm surge; and can store huge amounts of floodwater, reducing the threat of flooding in low - lying coastal areas.

In the former, we try to suck carbon dioxide out of the atmosphere and get it back in the ground; or we shunt CO2 aside at the smokestack before it gets to the atmosphere, and bury or store it; or we promote algae blooms that absorb CO2 at the ocean surface and then die off and carry it to the ocean floor.

As the international community and domestic lawmakers figure out how to meet their emissions reductions targets in a cost - effective way, many are looking to innovative mechanisms that channel finance towards enhancing the ability of forests and other natural land areas to absorb carbon from our atmosphere.

QUOTE: «As shown on figure 17 - D the regions for absorption and out - gassing are separate; there is no «global» equilibrium between the atmosphere and the ocean; carbon absorbed tens of years ago at high latitudes is resurfacing in up - wellings; carbon absorbed by plants months to centuries ago is degassed by soils Sorry, there is a fundamental lack of knowledge of dynamic systems here: as long as the total of the CO2 influxes is the same as the total of the CO2 outfluxes, nothing happens in the atmosphere.

As shown on figure 17 - D the regions for absorption and out - gassing are separate; there is no «global» equilibrium between the atmosphere and the ocean; carbon absorbed tens of years ago at high latitudes is resurfacing in upwellings; carbon absorbed by plants months to centuries ago is degassed by soils.

Researchers at Lawrence Berkeley National Laboratory have found to their surprise that despite the increased human emissions of greenhouse gases, between 2002 and 2014, plants were somehow able to absorb more carbon dioxide out of the atmosphere than in previous decades.

When Eli last left the bunnies, he was pointing out how gravity explains much of the greenhouse effect, well, except for the part that you need some things in the atmosphere that absorb IR radiation from the surface.

CO2 is a radiative gas that absorbs a thin slice of out - going radiation and, since re-emission time is magnitudes more than collision time, thermalises that energy to the remaining 99.96 % of the atmosphere.

Did you figure out that adding a trace amount of CO2 to atmosphere alters its albedo in the infrared spectrum causing it to absorb and thermalize more infrared light?

This is possible only because most of this radiation is absorbed in the atmosphere, and what actually escapes out into space is mostly emitted from colder atmosphere.

Since the steady - state temperature of the earth is determined by the balance between what it receives from the sun and what it emits back out into space, an IR - absorbing atmosphere will in fact cause the earth's steady - state temperature to be higher than it would be if the atmosphere did not absorb IR.

more carbon dioxide in the lower atmosphere means more little «point sources» for more absorbed EM in the infrared part of the spectrum, (infrared that re-radiated from the earth's surface after sunlight hit it and got absorbed); and since point sources radiate in a spherical pattern, that means more «back radiation» to earth, on balance... and this changes the «standing pattern» of energy flow in and out of the earth system, creating a time differential, so it starts to re-adjust...

I have tried to say things several ways, but I always profess that there is «upward thermal IR from the surface» (~ 396 W / m ^ 2, most of which gets absorbed by the atmosphere, but some passes directly thru the atmosphere and out into space) and a «downward thermal IR from the atmosphere» (~ 333 W / m ^ 2, nearly all of which gets absorbed by the surface).

Otherwise, such a hypothesis does not even satisfy the First Law of Thermodynamics (basically, conservation of energy): Without substances in the atmosphere that absorb terrestrial radiation, the earth's surface at its present temperature would be emitting back out into space way more energy than it receives from the sun and hence would rapidly cool down.

This made it possible to dissect each layer of Earth's atmosphere and work out how it might absorb infra - red radiation.

At its most basic, global warming is trivial, and beyond any doubt: add more energy to a system (by adding more infra - red absorbing carbon dioxide to the atmosphere), and the system gets hotter (because, being knocked out of equilibrium, it will heat up faster than it loses heat to space, up and until it reaches a new equilibrium).
