My research indicates that the Siberian peat moss, Arctic tundra, and methal hydrates (frozen methane at the bottom of the ocean) all have an excellent chance of melting and releasing their stored co2.Recent methane concentration figures also hit the news last week, and methane has increased after a
long time being steady.The forests of north america are drying out and are very susceptible to massive insect infestations and wildfires, and the massive die offs - 25 % of total forests, have begun.And, the most recent stories on the Amazon forecast that with the change in rainfall patterns one third of the Amazon will dry and turn to grassland, thereby creating a domino cascade effect for the rest of the Amazon.With co2 levels risng faster now that the oceans have
reached carrying capacity, the oceans having become also more acidic, and the looming threat of a North Atlanic current shutdown (note the recent terrible news on salinity upwelling levels off Greenland,) and the change in cold water upwellings, leading to far less biomass for the fish to feed upon, all lead to the conclusion we may not have to worry about NASA completing its inventory of near

If we keep doing as we do now and getting what we get now, is it possible that the relatively small, evidently finite, noticeably frangible planet we inhabit will soon
reach a point when it is no
longer possible for
Earth's resources and ecosystem services to sustain either life as we know it or the human species?
I
reached out to Pierrehumbert because he is one of many authors of «Consequences of twenty - first - century policy for multi-millennial climate and sea - level change,» an important new Nature Climate Change analysis reinforcing past work showing a very, very, very
long impact (tens of millenniums) on the
Earth system — climatic, coastal and otherwise — from the carbon dioxide buildup driven by the conversion, in our lifetimes, of vast amounts of fossil fuels into useful energy.
I am curious as to what additional slower «
earth - system» feedbacks might be indicated by the release of the methane... i.e. what kind of biological changes might occur to arctic regions by the melting of permafrost and release of methane that will add a
longer - term feedback response that needs to accounted for before any sort of new equalibrium would be
reached.
But when you look at all the data, or when you look at
long - term trends, the only possible conclusion is that the
Earth is warming — precisely the conclusion the scientific community has
reached based on observations and fundamental physics.
At the current rate of progression, the increase in
Earth's
long - term average temperature will
reach 1.5 °C (2.7 °F) above the 1850 - 1900 average by 2040 and 2 °C (3.6 °F) will be
reached around 2065.
By altering the angles and the distances from which the sun's energy
reaches earth, the three overlapping cycles control the timing of global warming and cooling, and the
long term advance and retreat of glaciers.
I.e. solar activity was high in most of the 20th centiry and then peaked in about 1985, together with a 20 - 30 year heat lag (since it remained high until 1996 as well), and oceans take a few decades to equilbrate, (the same as summer takes about 6 weeks to
reach maximum temperature after the summer solstice, and every day it takes a few hours after noon to
reach maximum temperature), so the
earth has taken a few decades to
reach maximum temperature after the
long high in solar activity during the 20th century, and will now go down in temperature over the next few decades, with now both a negative PDO, and reduced solar activity.
«How
long does it take heat created on the Sun's surface to
reach Earth?
On the Moon, the effective buffering depth is ~ 1m, which for comparison gives about a tenth of the buffering capacity of the
Earth's atmosphere, while the sol is of course ~ 29 times as
long, so the temperature swing of the lunar surface is much greater,
reaching ~ 120C during the lunar day.
His hypothesis is that «
long - term variations in the amount of solar energy
reaching the
Earth are the main and principal reasons driving and defining the whole mechanism of climatic changes from the global warmings to the Little Ice Ages to the big glacial periods», not carbon dioxide.
Try, really try, to address just Jelbring's imaginary world, perfectly insulated above and below, ideal gas in between, near -
Earth gravity, infinite time for the system to
reach true thermodynamic equilibrium (or
long enough for a non-GHG to
reach thermal equilibrium through radiation, which is going to be a hell of a lot
longer than its thermal relaxation through conductivity for a gas on average 200 - 300K in temperature at 1 g).
I therefore predict, quite confidently, that the
Earth will never get more than slightly over halfway to the doom - and - gloom prediction of carbon dioxide doubling before it comes down on its own because burning fuel for power or heat becomes as passe as TV antennas on rooftops —
reaching for a signal that is no
longer there...
Global warming is expected to have far -
reaching,
long - lasting and, in many cases, devastating consequences for planet
Earth.
If one assumes that the current warming rate will simply continue, which is possible but by no means assured, then the
Earth's
long - term temperature change will
reach 1.5 degrees Celsius, or 2.7 degrees Fahrenheit, by 2040, and the 2 - degree guardrail by 2065.
Since to me (and many scientists, although some wanted a lot more corroborative evidence, which they've also gotten) it makes absolutely no sense to presume that the
earth would just go about its merry way and keep the climate nice and relatively stable for us (though this rare actual climate scientist pseudo skeptic seems to think it would, based upon some non scientific belief — see second half of this piece), when the
earth changes climate easily as it is, climate is ultimately an expression of energy, it is stabilized (right now) by the oceans and ice sheets, and increasing the number of
long term thermal radiation / heat energy absorbing and re radiating molecules to levels not seen on
earth in several million years would add an enormous influx of energy to the lower atmosphere
earth system, which would mildly warm the air and increasingly transfer energy to the
earth over time, which in turn would start to alter those stabilizing systems (and which, with increasing ocean energy retention and accelerating polar ice sheet melting at both ends of the globe, is exactly what we've been seeing) and start to reinforce the same process until a new stases would be
reached well after the atmospheric levels of ghg has stabilized.
There was some very effective stratospheric warming just after each time the coronal hole came around (the particles take
longer to
reach Earth than EM radiations, as they are travelling at less than the speed of light on a curved path), and subsequently the polar vortex shifted.
Maybe some sort of crushed comet could hit the upper atmosphere with a sort of spread - out shotgun blast of tiny particles, all vaporizing
long before they
reach the
earth, yet creating a «disturbance in the force.»
showing how EM radiation, heat and air / water kinetic energy (in cells, circulations, currents, weather systems and convection columns and so on) move and how
long they have to move before they
reach some kind of equilibrium would go some way to visualising why it takes time for the
earth system to respond to radiative forcing (commitment time lag).
If we
reach a «tipping point» of feedback between warming and greenhouse emissions, where the
Earth lurches into a state without Arctic ice, then the next ice age might be delayed far
longer.
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?
In Part One of «Fire From Heaven,» we saw how scientists sought to measure that fire, and how succeeding generations attained better and better values for what was
long termed the «solar constant» — roughly, the amount of energy per square meter
reaching the top of
Earth's atmosphere.
