This could potentially close the carbon cycle,» said Prof Yeo.

The primary objective of this work was to expand upon the capabilities of past GFDL models used to study climate on seasonal to centennial time scales by the addition of a comprehensive and interactive carbon cycle in the land, ocean and atmosphere to «close the carbon cycle» in the same way we do for water and energy in a traditional climate model.

The ESMs, by design, close the carbon cycle and are used to study the impact of climate change on ecosystems, ecosystem changes on climate and human activities on ecosystems.

Society can not close the carbon cycle if we need to collect emissions from millions of microturbines.

«The agricultural market might seem smaller, but it has a very large carbon footprint, and turning acid whey into a feedstock that animals can eat is an important example of the closed cycles that we need in a sustainable society,» Angenent says.

By demonstrating that key individual species within the ecosystem can play a disproportionally large role in carbon cycling, this study helps bring us a step closer to understanding the function these microbes play in larger questions of climate warming and increased acidity in the ocean.

The idea is that I would have the valve click back and forth all the way for many, many cycles and this might knock away the hard carbon deposits and allow the valve to close all the way again.

However, in the global mean, these changes sum to zero (or very close to it), and so the global mean sensitivity to global mean forcings is huge (or even undefined) and not very useful to understanding the eventual ice sheet growth or carbon cycle feedbacks.

These models do not include the major carbon cycle feedbacks, which only exacerbate the temperature rise, and bring potential extinction closer in time.

It's only when deforestation and other land use changes made a net shift of carbon in the short term carbon cycle from plants back into the atmosphere, that humans began to make a net positive return of CO2 into the atmosphere (although deforestation is essentially reversible in principle), and it's very true to point out that industrial scale animal husbandry with its high cost in fossil - fuel - derived energy does mean that what might otherwise be a relatively closed system of cycling CO2 from the atmosphere through plants and then animals and back to the atmosphere, does become net positive with respect to CO2 emissions.

Which is to say, the less of anything we burn, the closer we get to allowing the carbon cycle to balance.
