Sentences with phrase «complex carbon cycle»

I haven't yet studied the article in detail but my thoughts are that the relative uncertainties are high, as expected since the atmospheric CO2 level at a given time is the response of the complex carbon cycle to the net anthro increase (6 Gt from fossil + est 2 Gt from land use change), small but not negligible compared to the gross carbon cycle fluxes (90 Gt to / from ocean, 120 Gt to / from biosphere).

Within an international model intercomparison project, researchers were able to simulate the complex carbon cycle as well as vegetation dynamics in climate projections for the 21st century.

Now that atmospheric CO2 has risen well above its natural level, many aspects of this complex carbon cycle are changing.

Not exact matches

Carbon cycling within coastal waters is complex and the team sought to identify how carbon flows into and out of tidal wetlands, shelf waters and estuaries.

Tiny tree roots may seem like a small thing to be focusing on, but Susan E. Trumbore of the University of California at Irvine and Julia B. Gaudinski of the University of California at Santa Cruz note in an accompanying commentary that «unless we recognize that root behavior is as complex as that of its counterparts above ground, the rules governing allocation of carbon to roots and the role of roots in soil carbon cycling will remain well - kept secrets.»

«Much of the carbon cycling in the ocean happens unseen to the naked eye, and it involves a complex mix of processes involving microbes and molecules,» said Azam, a distinguished professor of marine microbiology.

The detailed mechanisms of how the oceans contribute to this global carbon cycle at the microscopic scale, and which microbes have a leadership role in the breakdown process, are complex and convoluted problems to solve.

The picture may be even more complex, and a response in ENSO may even involve perturbations of the carbon cycle.

3 By making mathematical models of the carbon cycle in order to understand how oxygen — critical for large, complex organisms — was able to build up in the atmosphere because of changes in how organic matter decays;

In more complex models that calculate atmospheric chemistry or the carbon cycle, the boundary conditions would instead be the emissions of ozone precursors or anthropogenic CO2.

And you're worried about communicating some extremely complex concepts like the carbon cycle and the greenhouse effect?

Obviously it did to some extent, since an amount representing under half of total emitted fossil carbon remains in the atmosphere, but why it didn't take all, or why it took any, are lost in the details of the complex ecological interactions involved in the carbon cycle.

Trees and other living organisms are key players in the global carbon cycle, a complex biogeochemical process in which carbon is exchanged among the atmosphere, the ocean, the biosphere and Earth's crust.

Second, using measured atmospheric CO2 concentrations short circuits two layers of modeling which themselves are major sources of uncertainty, namely, estimating global emissions and, then, estimating the atmospheric CO2 concentrations (based on complex models of the global carbon cycle).

Recognizing that the carbon cycle is very complex, so there are reasons that the simple comparison could be off (going either way of course), the chart suggests that only 20 % of the total anthropogenic CO2 emissions occurred in the same period where 50 % of the total change in atmospheric CO2 concentration were observed.

For example, Dr. Gattie states: «These are regions where advanced energy systems such as nuclear, high efficiency combined - cycle natural gas plants, CCS, and renewable energy can be implemented to meet complex and emerging economic and environmental needs and where carbon reduction can have the greatest climate impact (Gattie 2016b).»

These are regions where advanced energy systems such as nuclear, high efficiency combined - cycle natural gas plants, CCS, and renewable energy can be implemented to meet complex and emerging economic and environmental needs and where carbon reduction can have the greatest climate impact (Gattie 2016b).

The more complex explanation is even more sobering — carbon cycle models indicate that ~ 25 percent of CO2 from fossil fuel combustion will remain in the atmosphere for thousands of years, and ~ 7 percent longer than one hundred thousand years.

Firstly the title of the post is carbon cycle questions.This is an area that is one of the most difficult complex suite of problems for the cs community as it involves interaction with the biosphere and its irreducible limitations (read constraints).

The Carbon Cycle is a complex series of processes through which all of the carbon atoms on earth rotate.

I'll say the division of atmosphere -, ocean - and land - centric models is an important one as ocean holds the most heat, atmosphere is the modifier of absorbed energy, and land is the most complex (in carbon cycle) and important wrt agriculture, maybe equal amounts of code / computing time should be assigned to all of these?

To start with, the soil carbon cycle is dynamic and complex.

«the cycling of carbon, energy and water between the land and the atmosphere is much more complex.»

In the meantime, a steadily increasing understanding of other aspects of the complex carbon - cycle was ongoing.
