Not exact matches
In these areas, deep ocean
waters that are naturally rich in
carbon dioxide are upwelling and mixing with surface
waters that are
absorbing carbon dioxide from the
atmosphere.
For example, in higher latitudes such as northern Canada and Greenland, coastal
waters usually act as
carbon sinks,
absorbing excess
carbon dioxide from the
atmosphere.
Some gases in Earth's
atmosphere — mostly
water vapor and
carbon dioxide — let sunlight pass through mostly unhindered, but
absorb infrared light
from the ground.
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.
Surface
waters above Arctic methane seeps
absorbed 2,000 times more
carbon dioxide from the
atmosphere than the amount of methane that escaped into the
atmosphere from the same
waters.
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.
And big trees matter: they have a giant part in
absorbing carbon dioxide from the
atmosphere but their very height means that they must work harder to haul
water to the canopy.
Some of the heat flowing back toward space
from the Earth's surface is
absorbed by
water vapor,
carbon dioxide, ozone and several other gases in the
atmosphere and then re-radiated back toward the Earth's surface.
When
carbon dioxide from the
atmosphere is
absorbed into the ocean and mixes with sea
water, it forms carbonic acid.
Earth has a natural «greenhouse effect» that results
from gases like
water vapor,
carbon dioxide (CO2), and methane
absorbing heat radiated
from the Earth's surface and lower
atmosphere and radiating that heat back towards the surface.
So, even if
carbon dioxide in the
atmosphere increased a thousand-fold, and even if there was no
water vapor, there is a limit to how much IR CO2 can
absorb, and that limit is 10 % (or less) of all the IR emitted
from the surface.
Climate models encapsulate what we know about how the Sun's rays travel through the
atmosphere and how heat
from the surface of the Earth gets
absorbed by clouds,
water vapour and, of course,
carbon dioxide.
Ocean acidity is rising as sea
water absorbs more
carbon dioxide released into the
atmosphere from power plants and automobiles.
