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.

Researchers think that the carbon cycle turns over about 330 billion tonnes of carbon dioxide each year.

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

If China is putting in more than previously thought then some natural aspect of the carbon cycle must be taking out more.

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.

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.

That will help those who seek to understand the carbon cycle and with it, the consequences of greenhouse-gas-induced climate change.

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.

Thus, the life-cycle analysis shows that for every mile driven, the average electric car indirectly emits about six ounces of carbon-dioxide.

Before his writings on the carbon cycle, Mr Bethe produced several papers that endeavoured to pull together the whole theory of nuclear physics.

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