Sentences with phrase «outgassing which»

[10] Earlier still, a 200 - million year period of intermittent, widespread glaciation extending close to the equator (Snowball Earth) appears to have been ended suddenly, about 550 million years ago, by a colossal volcanic outgassing which raised the CO2 concentration of the atmosphere abruptly to 12 percent, about 350 times modern levels, causing extreme greenhouse conditions and carbonate deposition as limestone at the rate of about 1 mm per day.

Not exact matches

An artist's impression of the dwarf planet Ceres, which appears to have a water vapor atmosphere from outgassing on the object.

Regarding outgassing, please note this paper: http://www.climate.columbia.edu/sitefiles/file/2002Takahashi.pdf which is freely available, so no excuse for not reading it.

The rate at which CO2 is taken up can of course vary, but I don't think any projections (at least until 2100) show net outgassing.

Rising temperatures will cause outgassing of CO2 from the oceans, but its C12 / C13 ratio will be that of the atmosphere when sinking thermohaline circulation took the CO2 from the atmosphere ~ 1600 years ago, which is different from fossil fuels.

In that context, gravity waves roil and depressurize the oceans, and that then leads to outgassing of CO2 — it comes out of solution in the ocean and bubbles to the surface and their given capacitive couplings impacting pH runs back to ion form — which then impacts conductivity.

And remember, during deglaciations, outgassing from the oceans would have occurred in a context in which warming was occurring, but not an exogenous increase in atmospheric CO2 — and outgassing (or not!)

See: http://www.pnas.org/cgi/content/full/070047197 I agree with this theory and take it one step farther, that the gravity pattern changes are about roiling and outgassing of CO2, which then changes conductivity patterns.

And they found that the highest post-thaw emissions of nitrous oxide came from the bare peat soils: these emissions were fivefold those from still - frozen soils and matched the kind of outgassing observed in tropical soils, which are the world's largest natural land - based nitrous oxide source.

Many of the mechanisms are like that — the tides, the direct inductive heating, the heating caused by the days influx of falling meteorites — which incidentally is far greater than the rate of heat loss through outgassing, as meteoric dust and matter infalls at an average rate of at least millimeters per decade, from my own direct measurements — they have «impressively» large amounts of annual energy associated with them, right up to where you divide by the surface area of the earth and the number of seconds in a year.

http://theoilconundrum.blogspot.com/2012/03/co2-outgassing-model.html take a look at this chart in particular, which maps out the Temperature / CO2 concentration phase space via a random walk model of CO2 outgassing mixed with GHG feedback.

I did not realise that the planet Cantobtainia was completely sealed with a thick layer of cantobtainium (which prevents outgassing).

The inferred ocean uptake pattern shows the sum of two components: the natural carbon cycle in which CO2 is outgassed in the tropics and taken up in the extratropics, and the perturbation uptake of anthropogenic CO2.

I calculate Delta GT carbon = 6.5 * Delta T + 0.48 * emitted carbon, which I make to convert to 2.8 ppmv per degree C. That's much less than your figure, but given the timescales one would expect much more outgassing over a longer period because a greater quantity of water will warm.

Subduction of carbon - rich crust was surely a large source of CO2 outgassing and a prime cause of global warming, which peaked 50 My ago (Fig. 3b) with the Indo - Asian collision.

Fertilized Peatbog Decay — resulting from elevated CO2 causing disruption of the microbial ecology and a massive production of an enzyme that happens to reduce peat to DOC, which then mostly outgasses as CO2 in outflow streams.

RealClimate is wonderful, and an excellent source of reliable information.As I've said before, methane is an extremely dangerous component to global warming.Comment # 20 is correct.There is a sharp melting point to frozen methane.A huge increase in the release of methane could happen within the next 50 years.At what point in the Earth's temperature rise and the rise of co2 would a huge methane melt occur?No one has answered that definitive issue.If I ask you all at what point would huge amounts of extra methane start melting, i.e at what temperature rise of the ocean near the Artic methane ice deposits would the methane melt, or at what point in the rise of co2 concentrations in the atmosphere would the methane melt, I believe that no one could currently tell me the actual answer as to where the sharp melting point exists.Of course, once that tipping point has been reached, and billions of tons of methane outgass from what had been locked stores of methane, locked away for an eternity, it is exactly the same as the burning of stored fossil fuels which have been stored for an eternity as well.And even though methane does not have as long a life as co2, while it is around in the air it can cause other tipping points, i.e. permafrost melting, to arrive much sooner.I will reiterate what I've said before on this and other sites.Methane is a hugely underreported, underestimated risk.How about RealClimate attempts to model exactly what would happen to other tipping points, such as the melting permafrost, if indeed a huge increase in the melting of the methal hydrate ice WERE to occur within the next 50 years.My amateur guess is that the huge, albeit temporary, increase in methane over even three or four decades might push other relevent tipping points to arrive much, much, sooner than they normally would, thereby vastly incresing negative feedback mechanisms.We KNOW that quick, huge, changes occured in the Earth's climate in the past.See other relevent posts in the past from Realclimate.Climate often does not change slowly, but undergoes huge, quick, changes periodically, due to negative feedbacks accumulating, and tipping the climate to a quick change.Why should the danger from huge potential methane releases be vievwed with any less trepidation?

There is no outgassing with our organic cotton fleece long johns, unlike recycled plastic fleece, which is made from plastic (recycling is good, but plastic is still plastic and petroleum - based).

The net impact of the 2015 — 2016 El Niño event on the global carbon cycle is an increase in atmospheric CO2 concentrations, which would likely be larger if it were not for the reduction in outgassing from the ocean.

One proposed solution to the first question involves the outgassing of massive amounts of carbon dioxide by volcanoes, which could have warmed the planetary surface rapidly by enhancing the planet's so - called greenhouse effect, especially given that major carbon dioxide sinks (rock weathering and photosynthesis) would have been dampened by a frozen Earth.

Also, make sure you explain the reduction in atmospheric oxygen, which wouldnt be happening if the carbon dioxide increase was due to oceanic outgassing.
