地球变暖 冰川消融

      全球气候变暖已是一个不争的事实,然而给地球生态和人类社会经济带来的不利影响更是人们议论的热点。也许它对现在的我们看似遥远,但事实上,全球变暖的速度超乎人们的预料。想象一下,或许用不了许久,北冰洋迎来的则是冰消雪融的夏季时光。更令人忧虑的是,北极圈冰层的融化现象很可能已形成恶性循环,摘录一段:

      “北极地区在非常大的程度上左右着全球气候的动向。就象一座大坝的溢洪道调控着水库的水位一样,两极地区控制着地球的热平衡。由于热带地区吸收的太阳能多于两极地区,风和洋流不断地把热量向两极输送,而两极地区大面积覆盖的冰雪影响着热量输运的结果。只要这一有很强反光性的冰雪覆盖层保持完好,覆盖在两极的大片地区上,那么直接射向北极地区的阳光绝大部分都会被反射回空间,这样北极地区将始终保持冰冷,有足够的能力容纳从低纬度地区输送来的热量。但如果冰雪覆盖层开始融化并收缩,它反射的阳光将减少,这样北极地区容纳热量的能力将被削弱,从而最终使整个地球的气候变暖。这反过来又会加速冰层的融化。”

       两年前,游轮去阿拉斯加,听说阿拉斯加冰川在以史无前例的速率后退,溶化速度比人们预想的要快得多,于是登冰川是我们旅途中的重点。一路收集了些资料,贴上供参考,望引起大家的关注。

     这是在  临降落时拍摄的一组照片

      冰川的形成需要几千年的时间,常年的积雪挤压和雨水形成了密度极高的冰(比一般冰的密度高十倍)。波长较长的光(如红色)被冰吸收,而波长较短的光(如蓝色)则被反射,所以我们看到的冰川呈透明的蓝颜色。

 

                                                    覆盖在山峰的冰盖已连续数年明显萎缩

        听飞行员说,一些冰川的表尺已经减少了好几百米,而且冰川溶化速度在过去十年里面显然加快,象现在的天气,一天甚至可以化掉5英尺! 可不?!

 

                                       有人计算,到2060年夏季,北极冰雪可能永远消失。

      飞行员还告诉我们,阿拉斯加冰川的冰块和水驰名世界,除日常饮用外,也是调制鸡尾酒的最佳用水。如果将冰川冰块打碎,加入任何饮料中,都能保持较久时间不溶化。把冰川水倒入杯中时,会看到不断有小气泡浮出水面,人工制造的冰块是不可比拟的。
       嘿,好好品尝一把(That was a once in a lifetime experience)!独特、纯净的阿拉斯加冰川水在《本草纲目》中描述为“冰川水能解人体百毒"。

 

                             海平面在上升,冰川在消失, 地球上的千年积冰在日渐融化。。。

 

几千年的见证,渐渐化为乌有!

                         大自然如此慷慨地展现她的活力和魅力,不知长此以往,冰川何存?!

    Hi Y N , great website, I didn\’t know that you\’re into philosophy that much, ; the thing about philosophy is that it\’s not applicable to all and anytime I found out not long ago, because before I thought they\’re perfect but recently I found out there\’s a flaw like e.g. "enjoy while you can, life is too short" because for many people their life have ended, but they have to continue on living unless they commit suicide.
    That is just 1 example, but don\’t get discourage to live by it because in your situation .
    Yes it\’s perfect!

    Hey, D W — thanks for your comment!
    Yeah, I know what the mean that you tried to explain to me. Well, my space may be a little different from others. Here, I\’d like to be more focusing on my OWN thoughts, interests, hobbies and even some articles from others which caught my eye …
    Since I know that something are no RIGHT or WRONG to argument about it, simply just because we are looking at a different angle, then we have a different way of thinking  —In other words, it is all about — Half full or half empty water in the glass…
    So, I am not going to give my opinion and try to convince others, but will be happy to hear my friends thoughts, idea, advice, suggestion  …
    That is why I don\’t like to "exposure" myself to the"public" too.
     
     HERE, I am ME, be myself —  and also really enjoy this place soooooooo much!
     
    Happy Valentine\’s Day for all of you and ME ^__^ !!!

    谢谢你一直以来的鼓励.

    再有十几年,几十年,地球暖化的问题会更严重,我觉得目前没有任何有效的解决方法,因为,人类无法做任何事来“拯救地球”,最多也仅仅是延缓全球变暖的速度而已。

    全球变热(有些科学家提出,将“全球变暖”的术语改为“全球变热”,因为“全球变暖”听起来太温和)已给地球生态平衡带来了严重的破坏。。。是呵,我从未想过要当个“拯救地球”的英雄,只是让我们在日常生活中多关注些,哪怕从一件微不足道的小事做起,尽可能减少自己对地球环境的负面影响吧。
    因为,我们只有一个地球,应该珍爱它。

    听了你的夸,乐了我半天喔 ^_^。嘿,今后就让我们多多交流吧。
    说真的,我很欣赏你笔风及摄影艺术,你呀,是个绝对会生活的聪明女人。对了,我觉得《阿妍生活日志》更适合你。
