Sentences with phrase «much outgassing»

Not exact matches

When previous research showed how much carbon dioxide was outgassing from rivers, scientists knew it didn't add up.

That would be wonderful if at least Atlantic TC reduce or do not increase with GW, since GW is and will be doing so much greater harm thru droughts, floods, disappearing glaciers, disease spread, ocean anoxia (with HS outgassing likely to follow), species loss, heat deaths,... am I leaving anything out?

It affects their bottom line research as much as the outgassing does so it should be part of the reporting, graphs and all.

I say CO2 simply follows ocean outgassing / absorption as it warms and cools and temperatures are bounded by planetary albedo i.e. how much land can potentially be locked under high albedo glaciers or alternatively how much can be exposed to present a lower albedo.

Chemistry tells us how much CO2 should rise from ocean outgassing with each degree and it is a small fraction of the rise that has actually occurred with the first degree of warming.

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.

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?
