This is in contrast to CO2,
which accumulates in the atmosphere / ocean system, meaning that steady (non-rising) emissions still lead to a rising atmospheric concentration.
Reducing longlived warming agents (predominantly CO2,
which accumulates in the atmosphere) reduces the slope (i.e. the long term rate of warming).
Not exact matches
So the only carbon used would be that
which already existed above the surface; it could no longer dangerously
accumulate in the
atmosphere.
In an article published in the journal Scientific Reports, the research team estimates that given the rate at which the peatland is now losing mercury back to the atmosphere, it will take just a few decades for all of the mercury pollution accumulated in the peatland to have disappeared, with most of it going back to the atmospher

accumulate in the
atmosphere and trap extra heat.
Seawater sulfate is a problem for methane
in two ways: Sulfate destroys methane directly,
which limits how much of the gas can escape the oceans and
accumulate in the
atmosphere.
Fossil fuels have been a great gift — but as the greenhouse gases produced by burning them
accumulate in the

which all life depends.
They document clearly how our burning of fossil fuels is releasing carbon dioxide and a series of other gases,
which are
accumulating in the
atmosphere and keeping
in more and more heat.
Other feedbacks include forests, and most importantly, water vapour,
which as the temperature of the
atmosphere rises increases
in the
atmosphere (think tropical rain forest), and water vapour is a potent greenhouse gas (but it is not the «controller» of our climate because it does not
accumulate in the
atmosphere, only gases like CO2, methane and nitrous oxide do this) See Skeptical Science https://skepticalscience.com/co2-lags-temperature.htm
Humans are emitting CO2,
which is
accumulating in the
atmosphere, and
which is a greenhouse gas.
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:
This leaves around 3 or 4 billion tonnes that are somehow being absorbed by the oceans, the land biosphere, or both.One possibility is that most of the man - made CO2
which does not
accumulate in the
atmosphere is being absorbed by the oceans... This view is supported by indirect evidence derived from the atmospheric nuclear bomb tests of the 1950s and 1960s.
But that's actually an understatement by Gallup, since more than 97 % of the world's climatologists say that those carbon gases,
which are given off by humans» burning of carbon - based fuels, are causing this planet's temperatures to rise over the long term, as those carbon gases
accumulate in the
atmosphere and also block the heat from being radiated back into outer space.
Since the temperature increase dates from the beginning of the industrial age and the warming apparently accelerates as greenhouse gasses
accumulate in the
atmosphere (picture below this), it is used as strong evidence of cause and effect and projected into the future (
which I'll write about later).
This is larger than the above 211 GtC that has
accumulated in the
atmosphere, but that's accounted for
in terms of Le Chatelier's principle,
which says that adding a chemical (CO2
in this case) to a system will shift its equilibrium resulting
in a certain fraction of the CO2 being taken up by the land and ocean.
And a large body of evidence shows that all those changes may be linked to the greenhouse gases created by human activity,
which are
accumulating in our
atmosphere.
In other words, carbon dioxide isn't accumulating in the real world because it is fully part of the Water Cycle and so in this shares water's residence time in the atmosphere which is 8 - 10 day

Additionally, a recent scientific paper revealed that HFCs actually do cause ozone depletion
which will be significant to the climate as concentrations of these gases continue to
accumulate in the
atmosphere.
Several greenhouse gases,
which are
in part or entirely produced by human activities, have
accumulated in the
atmosphere since approximately the middle of the 19th century.
A central hurdle is that carbon dioxide
accumulates in the
atmosphere like unpaid credit card debt as long as emissions exceed the rate at
which the gas is naturally removed from the
atmosphere by the oceans and plants.
Fossil fuels have been a great gift — but as the greenhouse gases produced by burning them
accumulate in the
atmosphere, our continued dependence on coal, oil, and natural gas poses a grave threat to the climate on
which all life depends.
The Earth escaped snowball conditions owing to limited weathering
in that state,
which allowed volcanic CO2 to
accumulate in the
atmosphere until there was enough CO2 for the high sensitivity to cause rapid deglaciation [103].
Hence, virtually all of the ecological overshoot comes from the EF's measure of the rate at
which carbon dioxide is
accumulating 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?
This method of comparison makes some sense when carbon dioxide is being compared to greenhouse gases such as HFCs,
which also
accumulate in the
atmosphere over long periods of time.
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.
If you (generic) can't see how ludicrous it is to think that a real gas
which has weight and volume behaves
in the
atmosphere as if an ideal gas
which has neither, and think that because the ideal imaginary gas spreads to fill the container according to its given properties means that a real gas CO2 behaves this way
in the
atmosphere, you'll be easily convinced that CO2 can diffuse and spreads as this imaginary gas and take it as perfectly logical then that because it is well mixed by this imaginary diffusion it stays that way and can stay
in the
atmosphere for hundreds and even thousands of years
accumulating.
