New Photos Show 'Devastating' Ice Loss On Everest

Simmeh writes "The BBC reports on new photos of the Himalayas taken from exactly the same position as ones from 1929 and compares the ice coverage. The Asia Society, which did the groundwork, are quoted as saying, 'If the present rate of melting continues, many of these glaciers will be severely diminished by the middle of this century.' I guess the previous claim wasn't too unrealistic."

    Nepal's power is run from hydro installed by the Russians many years ago. The generators are on the rivers that contain run-off from the Himalayas. I used to live there ('99-'01) and there was enough problems with lack of water then for us to have many brown outs. But lately, friends over there have been telling me that the power has been out for weeks on end, with hospitals, etc, having to constantly run their diesel generators, increasing the already excessive amount of pollution in the air, especially around Kathmandu. They've been saying that it's because the rivers have had hardly any water in them, which is caused by the decreasing amount of ice on the mountains.

    Unfortunately, the images in TFA are a bit misleading, as they are not taken from the same point. If you look closely, you'll find that the black and white image only starts about 20% into the left of the color image, and similarly the color image ends too soon, about 20% on the right of the black and white image.

    To visually compare the images properly, the color image needs to be turned into grayscale, and the two images need to be cut so that they can be properly superimposed. When this is done, the loss is a bit less impressive, but still noticeable in the valley if not on the mountains.

    Since I live very close to himalayas, I can say with confidence, that things have changed quite a bit.
    Is it global warming/regional warming or no warming, I dunno.
    But over the past 6-7 years these changes have forced farmers to change crop cycles, modified travel plans of seasonal roads, etc., etc.,

    Basically, in the Western himalayas, around November, snowfalls would start, seasonal roads would close by december, and jan feb were heavy snowfall months, with some in April and may.

    Now from past few years, there is hardly any snow during December and even January, which leads to lousy apple crop.
    Then in feb, it snows some, and in April may and june, well heavy snowfall in higher reaches.
    This kills the standing crop.
    The entire north India reels under heat wave as there is hardly any winter rain. We start getting summer in feb instead of April.
    The mountains start getting snow.

    So is it warming or cooling. No idea, but its a big change from what has been happening since 1900 or so(when record keeping started).

    Winter rain, at the correct time, and winter snow at correct time is very important for healthy crops. all this cycle change has led to big problems.
    To add to that, monsoon summer rain has also reduced. Thankfully, this year, though a bit late, monsoon is mostly adequate, but then here also instead of sustained rain over few days, most places get a cloudburst like havoc creating spell, and then its humid and dry. The dams will get filled up, but areas depending only on rain will suffer.
    Such rains also lead to big landslides.

    Part of the blame is on local deforestation, and micro climate change in the Himalayan region due to rapid commercialization and deforestation. Since protecting the environment is not yet a major election issue, its just a lip service on world environment day, when we switch of lights for an hour(and then get the routine 10 hour power cut due to overload of AC).

    So all in all, pics or no pics, the local weather in western himalayas has changed. Hopefully, this weather pattern will stabilize, and farmers will switch there crop sowing times. But since its still too erratic, its a big problem.

    As for global warming, when I see the temperature records for the region since 1900, the average temp has been rising steadily in most places, but whether this warming is caused by humans or not, I dunno. I am not a climatologist and like many people here, I will refrain from posting my theories on the changes.
    All that matters to many, is that its getting hotter and drier, and rainfall patterns are shifting alarmingly.
    Many glaciers in central himalayas are indeed receding, and its a fact. Not that they are warmer now, but because from past few years, there has been little winter snow in these areas.
    The ski slopes of Auli, which used to be snowed out in winters, now are devoid of snow many times. Last year Auli did not get a snow season.
    This year in June higher reaches of himachal got a few feet of snow. Not unusual, but definitely unusual in the peak of summer!

    So the weather is changing, but who is changing it I dunno. I hope it can be fixed, because it causing a lot of food supply problems. Fruits are out of reach of many, and if this continues, even cereals will become precious.

    "It takes quite a bit of arrogance to believe that humanity can change the Earth's climate that much, that fast."

    Earth's surface: 510,072,000 Km^2
    Earth's population: 6,856,832,000

    Mean earth surface per inhabitant: 0,074 Km^2/habitant, or, to give it in "real international standards units", about 13,7 football fields.

    Do you really think it takes too much arrogance to imagine that a single man can alter 13,7 football fields within his lifetime through farming, mining, driving, building, etc.?

    As opposed to the sun which has a surface area of 6088000000000 Km^2 ?

    That's 887 Km^2/habitant, or 164,377 of your "real international standards units" (football fields).

    Do you really think it takes too much arrogance to imagine that the variations in radiation from a superheated ball of gas at 5505C (9941F) might, just possibly, have some bearing on the situation ?

    The sun may very well may have a bearing on the situation but you are not going to convince anybody that digging and pumping up billions of years worth of sequestered carbon over the last 60-70 years and releasing it into the atmosphere with wild abandon had no effect at all. But let's put the climate debate aside for a moment. He was talking pretty generally about the way that humans are affecting their environment. Facts like a drop in the wold tiger population from 100.000 at the beginning of the century to a mere 3000 today can hardly be blamed on the sun, there are huge areas of dead ocean where nothing survives in any numbers you can make a profit from catching and selling, the list goes on... Changes like that are undeniably due to human excesses, mismanagement, corruption, greed and very little else.
