The Sun is important because it provides the Earth heat, it creates our daylight by emiting electromagnetic radiation, it allows plants to grow via photosynthesis which in
turn absorb carbon dioxide and create oxygen.
These give off oxygen which the coral polyps breathe; the algae, in
turn absorb the carbon dioxide which the polyps give off, forming thus a genuine symbiotic relationship.
Not exact matches
Eating less meat will free up a lot of agricultural land which can revert to growing trees and other vegetation, which, in
turn, will
absorb more
carbon dioxide from the atmosphere.
The nanowires collect sunlight, much like the light -
absorbing layer on a solar panel, and the bacteria use the energy from that sunlight to carry out chemical reactions that
turn carbon dioxide into a liquid fuel such as isopropanol.
The world's largest ocean is
absorbing carbon dioxide, and
turning more acidic as a result, faster than expected
Instead of dissipating into space, the infrared radiation that is
absorbed by atmospheric water vapor or
carbon dioxide produces heating, which in
turn makes the earths surface warmer.
When plants are
turned into fuel and then burned, the
carbon released is just what the plants
absorbed, potentially offsetting the emissions.
just a small example: rain washes CO2 from the air into the sea - > water
turns CO2 into carbonic acid - > coral
absorbs that compound — > keeps the
carbon for itself - > releases the oxygen from the CO2 molecule, to replenish the seawater with oxygen.
More generally, increased vegetation cover lowers albedo, meaning that more of the sun's light is
absorbed which in
turn warms the climate locally (another positive feedback), as well as increasing evapotranspiration and
carbon uptake.
During summers in the Northern Hemisphere, the Earth breathes in
carbon dioxide as green plants (most of which are north of the equator)
absorb the gas and
turn it into carbohydrate.
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.
Some propose that hundreds of millions of hectares of the Earth's surface be
turned into industrial tree plantations to produce charcoal to bury, even claiming this biochar could
absorb enough
carbon to return to pre-industrial
carbon dioxide levels.
Meanwhile, the wildly complex interactions and interdependencies between climate and planetary life are revealing increasingly dire stakes, as global warming leads to the shriveling of biologically diverse — and
carbon dioxide -
absorbing — forests and wetlands, which in
turn contributes to yet more warming.
Note the large negative spikes when geoengineering is
turned off: the land, adjusting to the sudden warming, spits out much of the
carbon that it had previously
absorbed.
Others suggest dumping iron filings into the ocean to increase the growth of algae which, in
turn, would
absorb more
carbon dioxide.
That, in
turn, slows down the destruction of forests in places such as Brazil and Southeast Asia and leaves more spaces able to
absorb carbon.
Oceans have always
absorbed part of the
carbon dioxide, or CO2, present in the air, which in
turn makes them acid.
Sharks sit atop the nautical food chain and subsist on midlevel ocean life, which in
turn feeds on plankton, whose biological processes
absorb carbon dioxide.
And if we are going to think that expansively about how we might use our streetscape, we might go even further, to imagine a few parking spaces per building permanently
turned into «eco-spaces,» with islands bulging into the streets to calm traffic, with plantings to
absorb rainfall that would otherwise flow into the sewers and to
absorb carbon dioxide and release oxygen, perhaps with small - scale rat - proofed composting receptacles, or igloos for depositing recyclables, or... the mind reels.
The backdrop, from a Guardian story, is this: Arctic seas
turn to acid, putting vital food chain at risk, With the world's oceans
absorbing six million tonnes of
carbon a day, a leading oceanographer warns of eco disaster.
But with limited nitrogen (red) and nitrogen and phosphorus (blue), the land releases more
carbon than it
absorbs,
turning it from a
carbon sink to a
carbon source.
