First off, I'm not a scientist, but from what I've read, I don't think the melting of the permafrost is going to help anything, and it's melting due to natural cycles. The end is here. Einstein said there's going to be a pole shift in 2012. I think a pole shift killed the dinosaurs. I don't think the algae did because "smaller" species of animals survived, and they drank the same water. Something happened to the food chain. A nuclear winter perhaps. If New York is inspired to erupt by earthquakes, as was written by the Aztecs, that is very possible.

Amusing concept. At this point, it seems to be a race to see what will kill off the human species first: global warming/climate change, the disappearance of natural ice worldwide, population overload and crash, destruction of our monocrop agriculture from lack of glacial water, and now toxic algae...I don't think 2012 is going to be the end of anything in particular (other than our crumbling economic system and perhaps the American government) but I think within the next thousand years, humanity's "civilization" will be drastically curtailed. No Armageddon, but instead think of a souffle that sinks. Doom is ahead, but slowly.

(Part I of VI)Algae and cyano(and other mid chain anaerobic-aerobic) bacterial population shifts are well known to parallel the nutrient milleu regional shifts that occur predominantly through natural Earth/soil/sea/atmosphere events which may be decades and centuries to eons apart. Mineral content changes from air/particle mass windblown effects from the Great Sahara across the Atlantic(as well as other mass transport convection systems elsewhere) result in parallel "Red Algae" blooms and regional coral reef infectious die-off fronts. Whether this is due to purely mineral nutrient effects or the transport of micronized loads of foreign bacterial/algae or phages/viruses is not determined yet. Settling of components into sediment alters the sea bottom milleu by either changing the oxidation-reduction constituents(shifting to anerobic predominance) or toxicly depressing the present aerobic/anaerobic species balance to favor cyanobacteria/toxifying algae, etc) and changing the food chain through the entire micro to macrocosm. Similar changes result from 1) Volcanic atmospheric output(which in massive amounts are part of many extinction patterns) which deposit into the sea through direct eventual fallout and to land based transport, erosion and cheimical dissolution run off through coasts and estuaries, 2) Cosmic atmosheric loading due to annual accumulation of micro/macro metoer, celestial dust trail passage(comet paths, sparse celestial cataclism regions and trails) as well as detected and presumed large body impacts, 3) Dissolved gases and mineral shifts convected in deep and rising ocean currents due to percolation water vents, black smokers, undersea volcanoes of steady and eruptive states(which account for 80% all volcanic output annually), (cont'd)

(Part II/VI).......4) Regional surface soil changes(melting permafrost, precipitation pattern changes) releasing or allowing flourishing of bacterial/algal populations previously locked out, with their susequent discharge into seas, 5) sea floor load shifts and dispersals due to unmasking of stored fields(Methane hydrate-[stimulating cyanobacteria], salt plumes, oil sediments, limestone deposits) and their complex inducements from and reactions to aforementioned milleu changes, seismic activity, changes in deep continental shelf run-off erosive patterns. Surface land exposure and physico-chemical changes to run off solution loads also occurs to lime, chalk, other mineral deposit new exposures or change in local rain/sea water characteristics altered by all the former. The effects of these occurrences in mega-tonnage/annum and effect averaged across the World or large regions dwarf any contributions to Human industrial and environmental concerns except in the smallest microcosm of simple lakes or estuaries in short range and timescale. A meager attempt at changing sea surface algal populations for the purpose of increasing CO2 uptake and slow global warming through introduction of "rust dust" is a short sighted example with ignorance of full system analysis contributions and consequences. The surface algae may shift, however, the iron-oxide load to mid water column and sediment precitation will suppress aerobic bacteria and other species, cause an oxidation-reduction balance shift and alter the regional food chain patterns for periods until chemical change and convective sources redistribute the components back toward norm. however,

the transient effects can give a picture to shallow observers in the short run of not only algal shifts, but, also, unpredicted life level die offs, such as feeding chain levels of other plankton, fish and corals, sponges, etc. The buffering capacity of the planet Earth's seas and land and atmosphere far exceeds the capacities of mankind to make anything significant if averaged over load and the time of years to decades, and is doubtful in even shorter timespans if one considers the human output compared to the Solar, Cosmic, Weathering, Erosion and Volcanic outputs per annum, often thrown far beyond Man's achievements with just one visible incidence of Earth's passage in Space, one seismic event, one volcanic eruption or even, at a quite smaller level, one land wild fire catastrophe, all of which happen over a few days. Mindfully note, that these are the visible phenomena at reasonably attended areas and times, and over 80% of such go unwitnessed in subterranean, sub-oceanic or supra atmospheric regions across the entire globe, accessible or inaccessible-detectable. All the studiable contributory factors discussed here rely on stable time averaging of know factors such as Earth's Space constituent encounters in its Solar, star group, galaxial, universe path(of which we have sparse knowledge of past); Solar output stability; Earth tectonic pattern activity stability, which are unknowable in future projection over decades, and presently, w.r.t Tectonics, undergoing a decades long new flux which may parallel the Magnetic field dipping region in the Mid Atlantic off of Brazil, and the hypothesized prelude to Pole Shifting.

Since the late "70s to '80s, the Earth's mantle flow has been studied in general patterns through long range and indirect monitoring to depths of 100sKm. However, a shift has been detected across the Europe-Atlantic-N.American latitudes into a sweeping northward across higher latitudes, and the mantle flow temperatures are rising. What effects does this produce? Well, obviously increased ground deep heat, upward-radiation and convection, increased and changed tectonic plate pressures, and increased volcanism(mostly sub-oceanic, sub-glacial and subterranean in the form of ground water/gases migrations and shifts. The mid North Sub-Polar Antarctic sea floor has had a tectonic plate margin stable in diversion at ~1/2 inch per annum. Recent 1990s excursions discovered that this had increased 250% to 1 1/2 tp 1 3/4 inches per annum, and Black Smoker Vents were discovered, which increased in count from 1997-2009 with the last being contributed by Russian sea floor explorations for natural gas deposits. This increased volcanism adds mega-tons of mineral content to the Arctic, and subsequent Gulf Stream circuit currents and have importance in both the melt/refreeze temperature of Arctic ice(depressing the freezing point like rock salt on roadways) and the subsequent nutrient loads to all populations of algae and bacteria/plankton/etc in the water column paths and floor sediment precipitation of these currents, supplemented with additional releases of frozen bound minerals and organisms from ice shelves, glaciers and permafrost changes as well as delayed winter freezes as seen in Finnish Lapland today.

These loads will cycle through the Alantic Conveyer Belt sea current circulation, as well as alter air convection temperature and humidity patterns to alter regional hemispheric weather patterns. Again, Mankind's contribution to this is dwarfed just by the effect of the simple plate spread and smoker vent output. Global Warming analysts ignoring the total Earth/Cosmic system analysis including these act irresponsibly for misguided or other gains. The secondary consequences of this increased Sub-Arctic plate spread is the cascade shifting of all other World's tectonic plates. Presently, the Mid-Atlantic Ridge spread and activity is not reported increased, so logically and mechanically, the shift and give must happen at the opposite mid, low and southern latitudinal margins, and this has been seen to be progressing at an accelerated rate over the past two-to three decades, through the Pacific plate, and more critically, its eastern, northern and, now, southern margins. Alaska, the coastal sea floor off British Colmbia and California, the Cascade Range, Mexico, the Andes have all shown progressive increases in seismic activity, un matched in frequency and caliber by the mid and northern portions of the Pacific Plate's west margin(sticky margin). The Hawaian Kilohea, the Alaska's Range, the Tongas, Mt Erubus on Ross Island,Antarctica and Indonesia's "Son of Krakatoa" have all shown increased escalating and frequent volcanic activity, and seismic shifts into the phillipine plate, Indonesia, across the Indian Ocean floor into Northeast Africa and the Mediterranean have been observed in increased frequency over the past two decades with the latest being an astounding compensatory swing of New Zealand's southern tip 11 inches west over it's normal 3/4 inch annual progress.

All four perrenial lava lakes(Kilohea,Mt Erebus, and two in NE Africa) have maintained increasing activity, indicating changing effects of mid-plate mantle upwelling. The Mantle's cross latitudinal shifts in the northern Atlantic can also be seen paralleled in the Southern latitudes, explaining Mantle convection changes under the Antarctic rim. Remembering that 80% of volcanic activity in sub-oceanic, and that a great magnitude of deep seismic and volcanic activity is translated into suface continental geologic strata seepage and infiltration of heat and dissolving gases and mineral solutes, it is not unreasonable that the World is experiencing a present Mantle-Tectonic SubArctic origin change that will resultantly load the ocean waters and convection currents with changing mineral and gas contents that may secondarily alter surface ices and atmospheric patterns and produce an Earth cyclic evolution of algal and bacterial oceanic constituent change. Whether it is of short or long duration will tell if the Earth's buffering capacity will be taxed for a prolonged period.

Trying to interpret nature's path on a short term basis (eg "global warming", or "killer algae") may lead to more harmful effects when we attempt to intercede. Look at the example of introducing "silkworms" to North America....the gypsy moth invasion...which decimates forests more than any "natural" causes. The most perplexing problem in dealing with averting "killer algae" and "sequestering carbon" is that the ocean's buffering capacity, as outlined previously, is already stressed and the pH is dropping Very slightly. This may have an enormous effect on the ability of beneficial phytoplankton to survive- - especially considering that the ocean produces maybe one third of the oxygen we need to survive. We may all be slithering across the earth in search of life sustaining Oxygen if we attempt to interfere with natural processes on a grand scale. Nature has a way of healing itself in better fashion than when man attempts to "restore" rivers, or waterways or ecosystems, especially when we haven't been around long enough to witness what is "normal." Perhaps it is just our anthropocentric view of the universe that leads us to visions of doom. We should co-evolve with the changes we make as the major contributor to change in our own niches. (even Nostradamus didn't predict the day he would die)

Great stuff from Danewegh, to which I'll add an ad hominem without positive causal correlation. If you go back to the GEOS-West satellite photos after the Indonesian earthquake, you will see a very strange atmospheric convective current change in the following two weeks...I don't have to explain it, you can see it with your own eyes, moving from Australia up across the Pacific to Canada. Now I mention this because I watch atmospherics, so this jumped out at me, then a friend who is involved with ocean currents mentioned a short time later, that the North to South Humboldt current passing by Canada and the Pacific NW, had mysteriously and inexplicable risen in temperature by many degrees. So I drove over to the ocean and sure enough, you could swim in it. But a year later, the current had mysteriously dropped in temperature, I believe almost ten degrees, and now you can barely stick a toe in. Don't know if that goes towards Daneweghs observations, but consider that the heat capacity of the ocean is an order of magnitude or more than the heat capacity of the atmosphere, a little El Nino or a little El Nina has huge impact on the air temperatures, right now the snow is melted and there are daffodils and crocus in bloom north of the 49th parallel, and it's only the first week in February!! But unsubtle effects of sub-sea vulcanism doesn't fit the Global Carbon Caliphate franchise business plan!! Anyway, the NOAA satellite photos for GEOS-W are still up there, and so are the Humboldt Current ocean temperature surveys for those years, check it out!

The temperature rise in the trans Pacific current to Canada/NW America can be explained by both the mechanical distibuted force shift of the massive plate edge elevation/drop and the thermogenic release from the huge frictional occurance and pulverization at the margin. Just as the avalanche of snow or rock/soil landslide travels at faster than predicted rates, so does the plate fracture line, inducing the sunami. The friction produced at the rubble boundary, augmented by the crush/crumbling of loose material generates exponential frictional surface increases and, thus heat generation magnification of enormous and rapid confined release to vaporize water content and possibly mineral content, along with building static charge forces that convert the boundary to a composite gas/liquid/solid state making the shifting mass a virtual hovercraft in effect. The repulsion forces as well as frivctional decrease allows the faster than calculable transit of the avalanche, landslide or plate fracture uplift, and nothing is seen of the phase change of gas/liquid vs solid since the confined space, upon ceasing to move, immediately redistributes the heat and the boundary debris that lubricates its motion refreezes or resolidifies or consolidates. Thus, the avalanche becomes as solid as ice around a victim, the landslide base becomes a dense soil/rock composit(compared to ites surface) In the case of the submariner shift, some gases may escape, but instantly cool and dissolve in he water.

(II/II Cont'd)The loose dusty debris may be ejected as sediment and partly dissolve, or consolidate back in the boundary as mortar-form, but the massive plate friction heat distribution will slowly diffuse through the geolithic strata, aided by seepage through the fracture lines and changed hydrodynamic flows and take weeks to months to dissipate into the water above, influencing water plume/stream temperatures as well as causing convective/density dependent shifts. The energy dissipation from the plate shift could not be estimable for the water impulsion alone that generated the sunami, and a huge component existed to developed stored heat in the geo strata for progressive diffusive release, equivalent to magnitudes of H-Bombs ever experience. Therefore, the current warming and shift observation may be explainable just by frictional and deformation mechanics, let alone to changes in volcan-hydrothermal-smoker-seafloor diffusion activity that may have changed with this. Again, all mankinds history of input summated is dwarfed by this one natural occurrence and all the submariner thermonuclear device detonations in prior testing has yet to approach such effect even noticeable on such a grand oceanic current effect. Respect is meritted and industrialization once again must kowtow in homage. Is it surprising?- when a single Class V Tornado, let alone a hurricaine overwhelms any cummulative force man can display. We are small and insignificant the the Earth's natural processes, and rather than learn to counter the forces, we would be better to learn to maneuver and respond, and keep an eye out for the rough ride.Surf's up! Man-made Global Warming proponents and stock holders. Buy gold!

@Sarah: While algae aren't exactly helping, the permafrost melting isn't all natural I'm sorry to say. And as for pole shifting? As they say in the Bronx and Queens, 'Fuggedabouddit.' As in, even if it did happen, it won't be the end all, be all.......not to mention that a nuclear winter would have NOTHING to do with a pole shift anyway.{In fact the worst thing that might happen is a somewhat fidgety climate for about 5-10 years. After that, we could very well see summer in January and winter in July! Or something like that}
