«In any case, the results of our model study give a clear indication that the bipolar variability of sulfate deposits must be taken into consideration if the traces of large volcanic eruptions are to be deduced from ice cores,» says Dr. Krüger, «Several research groups that deal with this issue have already contacted us to verify their data through our model results.»

Based on these figures, I suppose that the West Greenland ice melting was larger in the 1930 - 1950 period than in the 1985 - 2005 period...

That calibration enabled the researchers to detect high reflectance deposits consistent with surface ice in three large craters for which only off - nadir detections were available.

«This deposit is probably more accessible than most water ice on Mars, because it is at a relatively low latitude and it lies in a flat, smooth area where landing a spacecraft would be easier than at some of the other areas with buried ice,» researcher Jack Holt of the University of Texas said in a statement.
Huge chunks of smooth, dazzlingly blue ice are deposited on the beach and with the changing tidal waters, you never quite know what the layout of the beach is going to be until you get there.

You also are clearly ignorant of the evidence for Neoproterozoic and Paleoproterozic «Snowball Earth» episodes, which not only involve near - global ice cover, but also would be followed by extremely hot postglacial climates with temperatures of 40 - 50C — not yet observed, but not yet ruled out by any geological deposits by any means.

Has anyone taken recently deposited firn, mechanically compressed it to form ice, aged it for a while, then analyzed the ice using the present ice core analysis techniques to see if the results agree with the present 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?
Quantities such as tree ring widths, coral growth, isotope variations in ice cores, ocean and lake sediments, cave deposits, fossils, ice cores, borehole temperatures, and glacier length records are correlated with climatic fluctuations.
The latter events left behind distinctive rock - sequences typically consisting of tillites (ancient boulder - clay, now solid rock) representing ice - deposited debris, overlain with a depositional break by cap - carbonates, chemical sediments of marine origin deposited during interglacials following global sea - level rises.
