Faster sea floor spreading, presumably associated
with more volcanic activity at subduction zones, and / or other increases
in volcanic activity or geologic outgassing, or faster oxidation of exposed fossil organic C (as
in shales)-- greater geologic CO2 emissions (I think another way of looking at the inorganic part is that any given region of sea floor has less time to
accumulate carbonate minerals from chemical weathering, so that C reservoir could shrink while others, including the
atmosphere, can grow).
They happen when magnetic energy that has
accumulated in the solar
atmosphere suddenly escapes
with the power of 10 million volcanic eruptions, as described by NASA.
True to form, Miller (working
with a script by «Capote» writer Dan Futterman and E. Max Frye) leaves specific, reductive motives
in the shadows, opting instead for a grey - toned
atmosphere of impossible wealth, corroded American ideals and a calm, patient, occasionally static sense of
accumulating dread.
Ideas that we should increase aerosol emissions to counteract global warming have been described as a «Faustian bargain» because that would imply an ever increasing amount of emissions
in order to match the
accumulated GHG
in the
atmosphere,
with ever increasing monetary and health costs.
«but a slow shift means the long - lived gases will have

I, along
with an increasing number of climate experts, agree
with you that cleaning up carbon dioxide that has
accumulated in the
atmosphere will prove critical for curtailing climate change, and that it is essential to accelerate the development of carbon removal solutions today.
However, while displacing all fossil fuel power plants
with solar and wind farms is necessary
in curbing the flow of additional greenhouse gases into our
atmosphere, it does nothing to capture the prevailing stock of greenhouse gases that has already
accumulated.
Understanding the significance of this last fact relies on the appreciation that displacing all fossil fuel power plants
with solar and wind farms, while necessary
in curbing the flow of additional greenhouse gases into our
atmosphere, does nothing to capture the prevailing stock of greenhouse gases
accumulated from 150 years of industrialization and that will remain
in the
atmosphere for upwards of a hundred or more years to come.
I prefer the trend of the
accumulated emissions, which is a near perfect fit for the observed accumulation
in the
atmosphere, above the temperature trend which is not so perfect... See and compare:
with:

with the added heat
in the
atmosphere and oceans due to greenhouse gas emissions, storms now occur
with increasing
accumulated energy and higher moisture loading.
Not only is it the largest ocean, it also contains the «oldest water» — that is the water that (due to a giant slow loop
in the thermohaline circulation) spends the longest time without contact
with the
atmosphere,
with the best chance of
accumulating CO2 (as carbonate) at the bottom.
The fraction of aCO2
in the
atmosphere is already about 9 %, partly because the human fraction of the inputs did grow to 5 % (8/150 GtC) over time, partly because it
accumulates over 5 years, as only 20 % of all CO2 is exchanged per year, thus also only 20 % of the aCO2, but only the deep oceans exchange it
with aCO2 free fresh deep ocean natural CO2, while ocean surface and vegetation give some aCO2 back
in the next season.
I might agree
with idea of «
accumulates for hundreds and thousands of years
in the
atmosphere» as being a scam.
Therefore, to understand what has happened
in the past, and what will happen as greenhouse gases continue to
accumulate in the
atmosphere, requires a familiarity
with the various aspects of the system, utilizing everything we have available — observations, theory, and computer modeling.
Of this 545 GtC, about 240 GtC (44 %) had
accumulated in the
atmosphere, 155 GtC (28 %) had been taken up
in the oceans
with slight consequent acidification, and 150 GtC (28 %) had
accumulated in terrestrial ecosystems.
You do have such an amazing molecule
in your fictional world, defying gravity it can stay up
in the
atmosphere for hundreds and even thousands of years
accumulating though it's one and a half times heavier than air, and,
with no heat capacity to spit at, it can trap heat, or, heck you can't even get your stories to say the same thing consistently, it becomes this great thermal blanket stopping heat escaping... just how much of that blanket is holes?
But
with carbon still
accumulating in the
atmosphere and
with Trump and other politicians around the world seeking to slow or sabotage a transition away from fossil fuels, then it goes to follow that enacting such an aggressive mitigation will be very difficult to manage without an overwhelming resistance to such harmful policy stances.
The AGW Greenhouse Effect has excised gravity as it has convection because it claims that carbon dioxide can
accumulate in the
atmosphere for hundreds and even thousands of years and for this it needed to take out any physics to do
with relative weight.
With the greenhouse gases already
accumulated in the
atmosphere, it would take less than 30 years for it to be inevitable that temperature would
in time reach 2 °C above the pre-industrial level if the global greenhouse - gas emissions stayed at their current rate.
In the 21st century, greenhouse gases have continued to accumulate in the atmosphere, just as they did in the 20th century, but global average surface air temperatures have stopped rising in tandem with the gase

But imagine if we were faced
with the same situation that we are
with carbon dioxide
in regards to litter (i.e. that we had let 800 billion tons of trash
accumulate in our ecosystems since the Industrial Revolution, much like we have
with carbon dioxide
in the
atmosphere).
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?
You claim chinas temperatures have continued to increase recently despite their coal burning and sulphate aerosols,
with no basic knowledge that 1) they have filters on the power stations to remove most particulate matter like this since the 1980's, and 2) CO2
accumulates in the
atmosphere overwhelming particulates, which are short lived
in the
atmosphere.
They will continue to
accumulate in the
atmosphere over the next years and possibly even decades, which together
with the inertia of the climate system will support further warming.
Burning fossil fuels not only pollutes our air directly
with irritants like particulate matter and soot, but as greenhouse gases
accumulate in the
atmosphere and average temperatures rise, they also contribute to higher levels of ground - level ozone that can cause acute and long - term respiratory problems.
