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.

    Before the climate gate emails were released I had heard of the "hockey stick" but I didn't look into it because I thought it was probably just anti-science oil company propaganda. But after hearing about the trick to "hide the decline", I looked into it more. Climate scientists wanted to get rid of the medieval warm period because if temps were just as warm in the recent past, then there couldn't be much worry about today. So they found some tree rings that showed temps were cool back in the medieval warm period. Problem was that some of these trees were saying that temps were also cool during the last 50 years. Instead of eliminating these lying trees from the data set, they covered up the inconvenient data for the last 50 years from the lying trees with thermometer measurements and left us to think that these lying trees were telling the truth about the temperatures 1000 years ago.

    There seems to be two main defenses given by the climate science community for these cover ups. One is that some of the trees don't show this "divergence" from the thermometer temperatures. But if it is true that they have trees that give good data, then why not exclude the trees that lie? They can't claim they're reluctant to cherry pick the trees because this whole temperature from tree rings procedure demands picking out trees that are growth limited only by temperature and not anything else like water or CO2, and therefore cherry picking is inherently part of the process. And besides, even if they ought to leave the lying trees in, that's still no excuse to "hide the decline" in the final results.

    The other defense is that other studies by other researchers using other proxies, like sediments, have come to similar conclusions about the medieval warm period. But that's kind of like saying "My methods may have been corrupt, but my good buddies who have defended my corrupt methods, have gotten similar results in their research." This defense doesn't alleviate my concerns. And even getting correct results doesn't justify corrupt methods.

    If you think my criticisms of the hockey stick are harsh, imagine what the climate science community would think if someone like an oil company used similar methods in some research. Imagine an oil company found the medieval warm period was much hotter than today, but their results were based in part on rings from trees that showed temperatures from the last 50 years were much hotter than they really were, and the oil companies hid the results from the lying trees by replacing them with thermometer temps. But of course nobody would criticize that method if sediment studies from other oil companies showed the same results, right?

    Ah, yes, that's the problem with climate scientists. They don't appreciate the personal impact of seeing scouring marks on mountains, so they forget that there's been an ice age recently!

    Uh, NO. No one ever said "the current interglacial period was all our fault". Ice ages and interglacials are caused by Milankovich cycles, small variations in the earth's orbit and axial tilt.

    It's just one thing: those orbital anomalies cause only a very, very small change in temperature by themselves. Not nearly enough to move the earth in and out of an ice age. Yet they have been found to be an excellent explanation for them. Why is that?

    Because of climate feedbacks. As white ice sheets melt and turns into dark ocean, the sun absorbs more of the energy striking it. As the oceans warm, their capacity to dissolve gases is reduced, causing them to release higher amounts of CO2 into the atmosphere. Causing further warming, causing further melting. The earth keeps warming, but all things that become warmer emit more heat radiation. Eventually it becomes hot enough that the heat radiation out is in balance with the additional energy absorbed. But by then the tiny change in temperature from an orbital change has turned an ice age into an interglacial.
