According to Radebaugh, the process probably proceeds much more

This is the source of the famous twin paradox: Following a round - trip journey on a spaceship traveling at some exceptionally high velocity, a traveler would return to

Send Wall - E up there with a shovel, and you can just keep reusing the same dust as it falls back down (
slowly)... A potential problem, though, is forward scattering — in particular, if the dust cloud is large enough to extend significantly beyond the disk of the sun as seen from
Earth, it might «focus» light on the
Earth more
than block it (of course it doesn't focus light, it would just seem like it from
Earth).
However, it has been known since the earliest general circulation simulations by Manabe that as the
Earth warms in response to increasing CO2, the precipitation increases much more
slowly than Clausius - Clapeyron would suggest — typically only 2 - 3 % per degree of warming.
Ice core studies in Greenland and Antarctica have shown that
Earth's climate can change abruptly, more like flipping a switch
than slowly turning a dial.
Several leading authorities on climate change have given a guarded welcome to research suggesting the
Earth may warm more
slowly than scientists had expected.
Since 2001, the average air temperature at
Earth's surface has risen more
slowly than it did in previous decades.
However,
Earth's history reveals sea level changes of as much as a few meters per century, even though the natural climate forcings changed much more
slowly than the present human - made forcing.
It seems likely that the
Earth's atmosphere had somewhat more CO2 half a billion years ago
than today; as the Sun
slowly grew brighter, the carbon cycle deposited more CO2 in the crust, keeping the temperature «just right.»
Those cycles operate on much longer timescales
than humans tend to worry about and regardless they would have the
earth very
slowly cooling with a new glacial cycle in 30 to 50 thousand years.
For any object at a higher temp
than the surroundings, anything that impedes the loss of heat to the surroundings (in the
earth's case, cold outer space) will cause the object to either rise in temp or cool more
slowly.
As climate change has warmed the
Earth, oceans have responded more
slowly than land environments.
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?
I would agree with that, and also add that the results might only be saying that the
earth / climate system absorbs more energy via impulses
than via
slowly changing forcings, which is a fairly normal property of a complex system if you think about it.
And then you'll
slowly come to realize that the person you've loved and trusted more
than anyone on
earth, is capable of treating you worse
than you'd ever thought imaginable or that he would ever be capable of.
