Sentences with phrase «overall carbon cycle»

Truly only one negative feedback in the planet's overall carbon cycle can act with sufficient speed and strength to avert catastrophic climate impacts: The dominant carbon - based life form on this planet will have to respond to the already painfully clear impacts of our carbon emissions by slashing those emissions sharply and eventually running the planet on carbon - negative power.

«It is premature even to attempt to guess how strong the overall carbon cycle feedback on climate change might be, but my hunch is that, in the worst case scenario, the carbon cycle feedback might eventually release as much CO2 as humans do, a sort of «matching funds» arrangement.

Not exact matches

The models must track how carbon dioxide and other greenhouse gases cycle through the whole system — how the gases interact with plant life, oceans, the atmosphere — and how this influences overall global temperatures.

Therefore, as long as the overall composition of other Earth - like planets are the similar to ours, we would expect them to sport a carbon cycle (either organic or inorganic), also providing a stable climate for them — as long as the planets remain within the temperature range where the carbon cycle can work.

The ups and downs of the cycle are seen as smaller wiggles in the overall rise of carbon dioxide over the past half - century as

By focusing soley on the equilibrium climate sensitivity, the authors do miss a lot of features important to people about the overall climate system — for example, what's the equilibrium sensitivity of the carbon cycle to the temperature change brought about by 2X CO2?

For the d13C levels of several parts of the carbon cycle see: http://homepage.mac.com/uriarte/carbon13.html There are only two sources of low d13C on earth: fossil fuels and vegetation decay, but as the biosphere is an overall carbon sink, thus specifically a 12C sink, it can't be a 13C sink.

The map also provides a better indication of the health and longevity of forests and how they contribute to the global carbon cycle and overall functioning of the Earth system.

And WRT to the residence time of CO2 in the atmosphere, individual molecules of CO2 may have a relatively short residence time due to the carbon cycle but the overall level remains fairly constant and does have a residence time of centuries.

You'll see that the limits that most concern the biogeochemists are not the limits of drilling and mining (what we used to call «non-renewable resources») but rather the limits that are tied to overall system dynamics — the carbon and nitrogen cycles, biodiversity loss, and so on.

In addition, a relatively small amount of uranium can produce a relatively large amount of energy, helping the overall energy cycle of an online nuclear plant to release no more carbon dioxide per kilowatt - hour than solar power, which must account for the manufacturing of photovoltaic cells.

We need greater attention on the strength of uncertain processes and feedbacks in the physical climate system (e.g. carbon cycle feedbacks, ice sheet dynamics)(NRC 2013), as well as on institutional and behavioral feedbacks associated with energy production and consumption, to determine scientifically plausible bounds on total warming and the overall behavior of the climate system (Heal and Millner 2014).

The overall net emission over this period = + 0.5 units yet we can see how anthropogenic and sea (e.g. warming) contribute equally to this figure while net natural emission (i.e. sea + land) is — 0.5 Do we really know enough about the carbon cycle, in particular the natural fluxes of CO2, to rule out that some thing like this is going on?

Climate models that include the dynamics of the carbon cycle suggest that the overall effect of carbon - climate interactions is a positive feedback.

Decrease, on a full fuel cycle basis, the overall impact and carbon footprint of alternative and renewable fuels and increase sustainability.

Overall, the trend in Phanerozoic ca follows that of the GEOCARBSULFvolc long - term carbon cycle model (Figure 4d, black line), except for the late Mesozoic (~ 140 Myr ago) where the fossil model yields somewhat lower ca.
