Nove fontes de lubrication accelera le movimento de nostre glacieros.
Languages of this post: Interlingua, English)
Ante multe tempore glaciologos discoperiva que le glacieros del mundo move como fluvios lentissime. Ma in un articulo in le "Scientific American," (Februario, 2008) Robin E. Bell scribe que recentemente on ha discoperite retes de aqua liquide sub le glacieros massive de Groenlandia e Antarctica que los lubrica e destabilisa, accelerante lor movimento verso le oceano de nostre planeta in un processo que poterea elevar le nivello del mar assatis rapidemente.
A causa del calefaction global, on ha observate lacos de aqua liquide sur iste glacieros, le quales flue per fissuras in illos a lor bases. Fontes de calor geothermic e le friction causate per le movimento del glacieros mesme anque adde a iste aqua liquide, e on ha anque detectate diverse numeros de lacos subglacial que complica le problemas del lubrication sub iste glacieros.
Assi il es possibile que lor movimento verso le mar accelerara assatis rapidemente, ma il es impossibile predicer exactemente quando. Si omne le glacieros del mundo cadeva a in le oceano, il haberea inundationes universal in le citates costal del mundo, e paises como Hollanda, Bangladesh, e omne le stato de Florida in le Statos Unite esserea completemente coperite per le aqua del mar.

New sources of lubrication are accelerating the movement of our glaciers.
A long time ago glaciologists discovered that the glaciers of the world move like very slow rivers. But in an article in the "Scientific American," (February, 2008) Robin E. Bell writes that recently networks of liquid water have been discovered under the massive ice sheets of Greenland and Antarctica that lubricate and destabilize them, accelerating their movement toward the ocean of our planet in a process that could raise sea level rather quickly.
Because of global warming, lakes of liquid water have been observed on top of these glaciers that flow through fissures in them toward their bases. Sources of geothermal heat and the friction caused by the movement of the glaciers themselves also add to this liquid water, and various subglacial lakes have been detected that complicate the lubrication problems under these glaciers.
It is thus possible that their movement toward the sea will accelerate rather rapidly, but it is impossible to predict exactly when. If all the glaciers of the world fell into the ocean, there would be universal floods in the coastal cities of the world, and countries like Holland, Bangladesh, and the entire state of Florida in the United States would be completely covered up by seawater.
