		<description>Are we suffering from the illness, amnesia, that is resulting in our forgetfulness with regard to the value of the Earth and its environs?  Or have we been mesmerized by a Tower of Babel?  Or both?

Perhaps we are forever forgetting about Earth and its environment because too many people, especially the economic powerbrokers, their bought-and-paid-for politicians and their minions in the mainstream media, are worshipping a &quot;totem&quot;. At least to me, there appear to be many too many people for whom the economy, in and of itself, is the primary object of their idolatry. This behavior is observable, obvious and flagrant. In many instances, these worshippers make what they evidently believe are rational arguments that suggest manmade financial and economic systems are somehow essential to, and an integral part of, God&#039;s Creation; that indicate the growth of the global economy will occur from now on, even after the Creation is ravaged and its frangible climate destabilized by unbridled overproduction, unchecked overconsumption and unregulated overpopulation activities of the human species. Aside from the &quot;Economic Colossus&quot; nothing matters to them.

Today, it appears that the financial system of the economic powerbrokers is collapsing like a &quot;house of cards&quot; and the real economy of the family of humanity is threatened. Experts in political economy are saying internally inconsistent and contradictory things. Communications about financials and the economy are generally confused and in disarray. Confidence and trust in the operating systems of finance and the global economy have been undermined by the invention of dodgy financial instruments and unsustainable business models as well as by the promulgation of con games and Ponzi schemes. Transparency, accountability and honesty in business activities have been largely vanquished. A great economic system is being undone by con artists, gamblers and cheats. In such circumstances, does the manmade colossus we call the global political economy remind you in some ways of a modern Tower of Babel?

Sincerely,

		<description>of course its a bad sign that high altitude glaciers are melting, its a VERY bad sign, however the river is NOT going to dry up or even significantly decrease in volume, unless something catastrophic happens to shift the wind patterns that drive the precipitation that forms the river.</description>

		<description>rivers are formed by precipitation, glaciers are formed by precipitation in consistently cold conditions. conditions warm, glaciers melt, however that will not change precipitation in the catchbasin without a change in ocean currents which could cause wind patterns to shift. until winds shift, the same amount of water will fall on the same mountain ranges.

dano, why don&#039;t YOU explain how the entire volume of a river is sourced by a glacier. I&#039;ve seen video of these headwaters, its a tiny, tiny volume compared to the total flow even a few hundred miles down stream.</description>

		<description>oh and for all the idiots, glaciers are melting at record rates.

show me the record flow rates for their rivers. show me the record floods. show me some f&#039;n EVIDENCE that glaciers and not the rain/snow that made them are the source of the water.

holy f&#039;n stupidity. I can&#039;t believe this myth is still promulgated. esp here. WTF.</description>

		<description>anyone who is such a idiot as to believe a glacier is a source of drinking water, is, well, a idiot.

glaciers form from frozen precipitation. - they are melting more because things are warming up (warmer warm days, warmer cold days) 

until ocean currents shift, which they may very well be doing (or soon?) wind patterns won&#039;t change.. (its happened before, and Will happen again.)

When the wind currents change (as a result of ocean currents changing) .... well, that will be some serious stuff going down.

the rivers won&#039;t change in volume if the same amount of water falls in the same catchbasin. (and it will as long as wind patterns don&#039;t change) its only a signal of global climate change when glaciers melt.

Please, try and think about the whole system.

all of you.


tiny trickles of water at the headwaters of a river do NOT make up the full volume of a river. unless you are a idiot.</description>

		<description>OK, having gone back and looked, I see that the Andes work (a fair number of papers, actually) isn&#039;t as thorough as I had thought (although perhaps I&#039;m recalling an article or post rather than a paper; if so I can&#039;t locate it now).  In any case, sections 5 and 6 in this recent review &lt;a href=&quot;http://www.geo.umass.edu/climate/papers2/vuille2008.pdf&quot; rel=&quot;nofollow&quot;&gt;paper&lt;/a&gt; seem to sum up the current state of the science in terms of impacts.  Unfortunately, while the projections of water supply reduction seem fairly specific, there isn&#039;t yet anything on what the reductions are likely to do (e.g. what the affect on agriculture will be if there is a 50% reduction in glacial runoff in a given watershed).  I suppose that gets away from glaciology and hydrology and into economics, agronomy and even sociology.  

While I&#039;m at it, here&#039;s the abstract:

&quot;Observations on glacier extent from Ecuador, Peru and Bolivia give a detailed and unequivocal account of rapid shrinkage of tropical Andean glaciers since the Little Ice Age (LIA). This retreat however, was not continuous but interrupted by several periods of stagnant or even advancing glaciers, most recently around the end of the 20th century. New data from mass balance networks established on over a dozen glaciers allows comparison of the glacier behavior in the inner and outer tropics. It appears that glacier variations are quite coherent throughout the region, despite different sensitivities to climatic forcing such as temperature, precipitation, humidity, etc. In parallel with the glacier retreat, climate in the tropical Andes has changed significantly over the past 50–60 years. Temperature in the Andes has increased by approximately 0.1 °C/decade, with only two of the last 20 years being below the 1961–90 average. Precipitation has slightly increased in the second half of the 20th century in the inner tropics and decreased in the outer tropics. The general pattern of moistening in the inner tropics and drying in the subtropical Andes is dynamically consistent with observed changes in the large-scale circulation, suggesting a strengthening of the tropical atmospheric circulation. Model projections of future climate change in the tropical Andes indicate a continued warming of the tropical troposphere throughout the 21st century, with a temperature increase that is enhanced at higher elevations. By the end of the 21st century, following the SRES A2 emission scenario, the tropical Andes may experience a massive warming on the order of 4.5–5 °C. Predicted changes in precipitation include an increase in precipitation during the wet season and a decrease during the dry season, which would effectively enhance the seasonal hydrological cycle in the tropical Andes.

&quot;These observed and predicted changes in climate affect the tropical glacier energy balance through its sensitivity to changes in atmospheric humidity (which governs sublimation), precipitation (whose variability induces a positive feedback on albedo) and cloudiness (which controls the incoming long-wave radiation). In the inner tropics air temperature also significantly influences the energy balance, albeit not through the sensible heat flux, but indirectly through fluctuations in the rain–snow line and hence changes in albedo and net radiation receipts.

&quot;Given the projected changes in climate, based on different IPCC scenarios for 2050 and 2080, simulations with a tropical glacier–climate model indicate that glaciers will continue to retreat. Many smaller, low-lying glaciers are already completely out of equilibrium with current climate and will disappear within a few decades. But even in catchments where glaciers do not completely disappear, the change in streamflow seasonality, due to the reduction of the glacial buffer during the dry season, will significantly affect the water availability downstream. In the short-term, as glaciers retreat and lose mass, they add to a temporary increase in runoff to which downstream users will quickly adapt, thereby raising serious sustainability concerns.&quot;</description>
