Not exact matches

The positive correlation indicates that the ocean outgasses CO2 compared to its mean state when the SAM is positive, i.e. when the winds are intensified South of 45ºS (20), and suggests that wind - driven upwelling and associated ventilation of the sub-surface waters rich in carbon dominates the variability in CO2 flux (18).

I don't need to explain it for my Model to remain valid.The concept of ocean outgassing in response to more sunlight is a useful add on but not an integral component because I do not ascribe significant climate forcing to that CO2.

My model is neutral as regards the actual source of the extra CO2 but would be consistent with ocean outgassing.

The emissions and their partitioning only include the fluxes that have changed since 1750, and not the natural CO2 fluxes (e.g., atmospheric CO2 uptake from weathering, outgassing of CO2 from lakes and rivers, and outgassing of CO2 by the ocean from carbon delivered by rivers) between the atmosphere, land and ocean reservoirs that existed before that time and still exist today.

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?

«All these processes give a taste of the complex interaction between sea ice, biological productivity, and deep water upwelling as mechanisms controlling CO2 outgassing in the Southern Ocean, particularly at the Antarctic Polar Front, where they are strongly coupled.»

During these events, the anoxic oceans outgassed enough toxic hydrogen sulfide to cause varying sizes of mass extinctions of marine and terrestrial life.

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.

When global temperatures increase, the oceans give up some of their CO2, outgassing it into the atmosphere and increasing atmospheric concentrations.

Strong AGW supporters on the other hand argue that while the sun may have caused the initial temperature spike and outgassing of CO2 from the oceans, further temperature increases were caused by the increases in CO2.

The time - lag between changes in temperature and consequent changes in CO2 concentration are caused by outgassing of CO2 from the oceans when they warm and uptake by the oceans as they cool.
