By seeing which wavelengths are
absorbed as the starlight passes
through the planet's atmosphere, astronomers could determine whether the atmosphere contains water,
carbon monoxide, methane, and
carbon dioxide.
In the springtime, there is a dramatic removal of
carbon from the atmosphere as plants
absorb carbon dioxide, using it
through photosynthesis to fuel their growth.
But will the world's biological systems
absorb more or less
carbon dioxide as they cycle it
through the atmosphere?
Just as in algae biofuel production on land, the floating OMEGA bags use water, solar energy and
carbon dioxide — which in this case is
absorbed through the plastic membrane — to produce sugar that algae metabolize into lipids.
Apparently, like some salamanders, this animal
absorbs oxygen and expels
carbon dioxide directly
through its skin.
Carbon - 14 can combine with oxygen in the atmosphere to create
carbon dioxide, which is then
absorbed by plants and makes its way
through the food chain.
The study's authors point to a future with greater reliance on nuclear and renewable energy, reducing emissions
through new technologies that capture and store
carbon dioxide, and expanding forests to naturally
absorb and store
carbon.
However,
through the process of photosynthesis, office plants can
absorb the
carbon dioxide and release oxygen reducing air pollution, stress, and a short attention span.
This is because the amount of CO2 released from E85 during combustion is practically identical to the level of
carbon dioxide the plants
absorbed from the atmosphere
through photosynthesis when they were growing.
The business plan had been to sell «
carbon offset» credits earned by triggering blooms of phytoplankton that, in theory, would
absorb a predictable amount of the climate - warming gas
carbon dioxide through photosynthesis and then sink to the seabed.
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.
Along with a boosted catch, a second hoped - for payoff was the sale of
carbon credits on international markets aimed at offsetting greenhouse gas pollution by financing projects that
absorb heat - trapping
carbon dioxide — typically by planting trees but in this case
through spurring plankton growth.
The amount of
carbon dioxide the plankton
absorbs will be the same whether the plankton bloom is generated
through iron seeding or from more «natural» occurrences.
Most ponds and lakes generally release more
carbon dioxide into the atmosphere
through the decomposition of organic material than they
absorb through photosynthesis.
Here are just some of the many benefits that these systems provide all at once: green infrastructure
absorbs and sequesters atmospheric
carbon dioxide (C02); filters air and water pollutants; stabilizes soil to prevent or reduce erosion; provides wildlife habitat; decreases solar heat gain; lowers the public cost of stormwater management infrastructure and provides flood control; and reduces energy usage
through passive heating and cooling.
Because of its molecular structure,
carbon dioxide is a greenhouse gas, which means it allows visible light from the Sun to pass
through the atmosphere while
absorbing and reemitting infrared energy, heating the Earth.
Through clear descriptions of actual scientific studies, a young reader
absorbs clues that are symptoms of global warming: rainforest deforestation, rising sea levels, and changing
carbon dioxide levels, to name a few.
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.
