Researchers think that the carbon cycle turns over about 330 billion tonnes of carbon dioxide each year.
ECONOMIST: Two new satellites will monitor carbon-dioxide emissions
That will help those who seek to understand the carbon cycle and with it, the consequences of greenhouse-gas-induced climate change.
With the additional data that the satellites provide, researchers hope finally to shed light on the Earth's complicated carbon cycle.

Researchers think that the carbon cycle adds up to the production of about 330 billion tonnes of carbon dioxide each year.

With satellites providing data from thousands of additional locations, researchers hope finally to shed light on the Earth's complicated carbon cycle.

We believe SOCAT will become an invaluable resource for anyone studying the ocean carbon cycle and its influence on global temperatures.
If China is putting in more than previously thought then some natural aspect of the carbon cycle must be taking out more.
Although this may look paltry in comparison to the total carbon cycle, it is probably enough to upset such a finely tuned system.

Before his writings on the carbon cycle, Mr Bethe produced several papers that endeavoured to pull together the whole theory of nuclear physics.
ECONOMIST: Hans Bethe, nuclear physicist, died on March 6th, aged 98
First, their models tended to ignore the myriad amplifying carbon cycle feedbacks that we now know are kicking in (such as the defrosting tundra).
In the natural carbon cycle, plants absorb CO2 as they grow.
ECONOMIST: Biochar could enrich soils and cut greenhouse gases as well
Life in the sea, after all, supports the basic processes that we all take for granted: the water cycle, the oxygen cycle, the carbon cycle, and much more.

If that idea is confirmed, it will need to be incorporated into the computer models used to understand the Earth's carbon cycle and its effect on the climate.

Oceans are considered to be one of the planet major players in the global carbon cycle, but the carbon uptake in the region where the eruption occurred has limited capacity.
Carbon dioxide pumped into carbon cycle, is not.
FORBES: Antarctic Temperatures Are Rising Twice As Fast As Previously Predicted
However, beyond the smokestack, looking at the full life-cycle accounting for carbon of various biomass feedstocks, other reports have found that the source of the feedstock matters.

As environmentalist Bjorn Lomborg notes, manufacturing and charging electric cars over their life cycle can produce more carbon than small, gas-powered vehicles.
To those concerned about emissions, it emphasized that the 400, 000-barrel-a-day refinery, plus an integrated gasification combined cycle plant, could sequester carbon more cheaply than a coal plant.
Having looked closely at the evidence, I have concluded that what really reduces carbon emissions is making sure you walk or cycle to the shops.
The seats are staggered, so the passenger sits both beside and behind the driver the car is narrow, with the cycle-fendered wheels out on carbon fiber struts.
The family then stopped using all carbon-producing transport, so they now walk or cycle.
The rising tree population could disrupt the natural processes that cycle snow and energy through the region and increase the amount of carbon it stores, according to the researchers.
According to a life-cycle analysis, the land-based crops all were found to sequester more carbon than that incurred in growing them, while the contrary was true for growing algae, meaning that replacing fossil fuels by algal fuels could cause an overall increase in carbon emissions.

Moreover, although controversial, life-cycle analysis indicates that fugitive methane emissions make shale gas obtained by hydraulic fracturing as carbon-intensive as coal.

According to scientists who conduct so-called "life cycle analysis" for solar, the transport of waste is not currently being factored into the carbon footprint score, which measures the amount of greenhouse gases produced when making a product.
This new edition of the guide the 17th since the first version was released in 2006 adds new criteria to evaluate companies based on their carbon footprint, use of renewable energy, sourcing of paper fiber and conflict minerals, and product life cycle analysis.
Thus, the life-cycle analysis shows that for every mile driven, the average electric car indirectly emits about six ounces of carbon-dioxide.
Natural gas emits 29% less carbon dioxide than oil and 45% less than coal, and it can be used in high-efficiency combined cycle power stations.
