A lot of others worldwide ! Greenland's Ice Layers Mapped in 3D Quoting: Anonymous Coward 67333401 2014 Was the Warmest Year on Record thanks for sharing ! Earth age is 4.54 billion years, higher forms of life age more than 500 million years. The very fact of their existence for so long means that there are a large number of well-known and as yet unknown mechanisms of feedback which largely soften of global cataclysms consequences each time when they happen , and generally returns of very complex "mechanism"with name of "Earth" if and not to original state , but at least to a new long-term condition of stability (up to the next disaster) . Namely it allows such a long time to exist and to evolve life on it . Of course, with inevitable costs, which we know as the periods of the "great extinctions", but even they eventually just reinforces evolution (why and how - is a separate issue). Known and still unknown us feedback mechanisms, should have a huge potential impact on the "mechanism" by the name of "Earth", otherwise they would not work the way they work . And here we come to the most important question, which unfortunately "deniers" of global climate change (special case - global warming) totally fail to understand : we do not know what, how and when might "switch on" these powerful mechanisms. That, when unexpectedly turns on , can unintentionally kill insects (ie us) which consider themselves omnipotent hosts of mother Earth . But we already know for sure that we able, themselves realizing, accidentally press the lever, which launches them. That is the essence of the problem of climate change why scientists with such alarm tracks the undeniable signs of global warming: lever already pressed or not? i think already at least on three-quarters (in the best case) |

Katla Hekla Iceland Dead Zone and rift as uniform system ! A lot of others worldwide ! arguing as philosophizing amateur, i would certainly say that this is true. how come? rift was born many millions of years before we began to talk here on GLP, and will die after many millions of years after we leave this frail world. He lives, and his whole life is a continuous chain of events - huge (hundreds) , not very small (a lot thousands) and very small (each day and billions). so, of course, what is happening now around (or rather under) Bard, event. However, from the standpoint of geological much more correct not to allocate this event into something very individual and extraordinary - "EVENT!" (the more so in geological terms it is not such), rather discuss it only as an good indicator of the beginning of a new cycle, new chain of notable geological processes in the life of the rift . Which, in turn, almost completely determined by the plates movements. Otherwise, each eruption of any of the many volcanoes in Iceland in the same way can be called "event Rift" - how otherwise, because they are all sitting on the rift and their activity directly depends on it. my guess its really rather earth crust response than the activity of the rift itself, not "rift event". rift only answers on "call" of crust :cool2" |

That, when unexpectedly turns on , can unintentionally kill insects (ie us) which consider themselves omnipotent hosts of mother Earth . But we already know for sure that we able, themselves realizing, accidentally press the lever, which launches them. That is the essence of the problem of climate change why scientists with such alarm tracks the undeniable signs of global warming: lever already pressed or not? i think already at least on three-quarters (in the best case) |

In south-central Iceland some sites are moving upward as much as 1.4 inches (35 mm) per year. it means already 350 mm only for last ten years? and with acceleration? YES, sir compare for example with current barda (so called somewhere) "terrible" movements: [link to www.vedur.is] maximum 70-80 mm from beginning of really not small eruption at 14-08-2014 |

A lot of others worldwide ! arguing as philosophizing amateur, i would certainly say that this is true. how come? rift was born many millions of years before we began to talk here on GLP, and will die after many millions of years after we leave this frail world. he lives, and his whole life is a continuous chain of events - huge (hundreds) , not very small (a lot thousands) and very small (each day and billions). so, of course, what is happening now around (or rather under) Barda, might be named "event". However, from the standpoint of geological much more correct not to allocate this event into something very individual and extraordinary - "EVENT!" (the more so in geological terms it is not such), rather discuss it only as an good indicator of the beginning of a new cycle, new chain of notable geological processes in the life of the rift . Which, in turn, almost completely determined by the plates movements. Otherwise, each eruption of any of the many volcanoes in Iceland in the same way can be called RIFT EVENT" - how otherwise? because they are all sitting on the rift and their activity directly depends on it. my guess its really rather earth crust response than the activity of the rift itself, not "rift event". rift only answers on "call" of crust " exactly |
