That's exactly what a group of chemical engineers and biochemists attempted in a new study, embedding single - walled carbon nanotubes — microscopic tubes thinner than a human hair that can also absorb sunlight and convert it to electron flow — in living chloroplasts.

Emissions of carbon dioxide are already far higher than the forests and oceans can absorb.

Over recent decades the remaining Amazon forest has acted as a vast «carbon sink» — absorbing more carbon from the atmosphere than it releases — helping to put a brake on the rate of climate change.

Coastal portions of the world's oceans, once believed to be a source of carbon dioxide (CO2) to the atmosphere, are now thought to absorb as much as two - thirds more carbon than they emitted in the preindustrial age, researchers estimate.

Tropical forests untouched by deforestation absorb huge amounts of carbon, more than all other northern hemisphere forests combined, the study found.

CO2 concentrations would start to fall immediately since the ocean and terrestrial biosphere would continue to absorb more carbon than they release as long as the CO2 level in the atmosphere is higher than pre-industrial levels (approximately).

If the Arctic Ocean is losing ice at a greater rate than previously thought, won't this increase the rate at which carbon dioxide is absorbed?

Fossil fuels ultimately derive from plant life, which preferentially absorb more of the lighter isotope carbon - 12 than the heavier isotope carbon - 13.

If so, these sites are growing faster than mature forests and may exaggerate the amount of carbon that can be absorbed by the forest as a whole.

«It also means that big, old trees are better at absorbing carbon from the atmosphere than has been commonly assumed.»

(b) agrarian economies are to blame for global warming, because they have deforested the land more than industrialized countries (an unproven assertion, but we'll let it pass) and so the earth is not able to absorb the increased atmospheric carbon that industrialized countries are pumping out.

Nevertheless, we know that a wooden frame can absorb shocks and impacts better than metal frames, and is more durable and has a smaller ecological footprint than metal too (Mohorič claims that you would save 14 kilograms in carbon emissions by using this bike over a metal one).

(Paper abstract) Soot from ships worse than expected Produced during combustion of fossil fuels and biofuels, light - absorbing carbon (soot) creates haze and absorbs light with an efficiency nearly one third that of carbon dioxide.

This doesn't prove anything about the capacity of the biosphere to hold that carbon indefinitely, but doesn't it at least prove, as SImpson says, that is is possible for the biosphere to absorb carbon at a more rapid instantaneous rate than we are currently emitting it?

Another paper in Science recently estimated that the world's 10 billion acres of forest are now absorbing about a third of carbon emissions, helping to limit carbon dioxide levels and keep the planet cooler than it would be otherwise.

And then the trees grown to absorb carbon would have to be stored deep underground, to prevent the carbon returning to the atmosphere to accelerate global warming rather than limit it.

Although global forests currently capture and store more carbon each year than they emit, 46 the ability of forests to act as large, global carbon absorbers («sinks») may be reduced by projected increased disturbances from insect outbreaks, 47 forest fire, 48 and drought, 49 leading to increases in tree mortality and carbon emissions.

Using the NDVI, one team this year reported that «over the last few decades of the 20th century, terrestrial ecosystems acted as net carbon sinks,» i.e., they absorbed more carbon than they were emitting, and «net greening was reported in all biomes,» though the effect had slowed down in recent years.
