  • 工作学习 / 科技杂谈 / 关于全球变暖,咱们先捋清facts, 再谈是不是man-made。先有个可以讨论的事实pool, 总是比七嘴八舌的瞎说要更有些科学精神,即使是民科精神也好。 +1
    • 1, 地球平均气温从19世纪以来提高了1点1摄氏度。最近35年尤其更暖,人类有记录以来最暖和的16个年份出现在2001年后。最暖和的一年是2016 +1
      The planet's average surface temperature has risen about 2.0 degrees Fahrenheit (1.1 degrees Celsius) since the late 19th century, Most of the warming occurred in the past 35 years, with 16 of the 17 warmest years on record occurring since 2001. 2016 the warmest year on record
    • 没有人类出现的时候地球就经过冰河世纪 也经过全球变暖 人类是渺小的 只会存在这一时期 人类终将消失 地球还会继续 所以人类讨论变暖就是个笑话 +1
      • (#11272461@0)
        • 对呀 那人类讨论地球变暖有啥意义 人类的存在只是地球生命的一个瞬间
    • 2. 全球700米深以上的海水温度从1969年以来上升了0.302华氏度 +1
      The oceans have absorbed much of this increased heat, with the top 700 meters (about 2,300 feet) of ocean showing warming of 0.302 degrees Fahrenheit since 1969.7
    • 3. 格陵兰岛和南极加速流失冰川 +1
      The Greenland and Antarctic ice sheets have decreased in mass. Data from NASA's Gravity Recovery and Climate Experiment show Greenland lost 150 to 250 cubic kilometers (36 to 60 cubic miles) of ice per year between 2002 and 2006, while Antarctica lost about 152 cubic kilometers (36 cubic miles) of ice between 2002 and 2005.
      • NASA Study: Mass Gains of Antarctic Ice Sheet Greater than Losses
        The research challenges the conclusions of other studies, including the Intergovernmental Panel on Climate Change’s (IPCC) 2013 report, which says that Antarctica is overall losing land ice.

        有同学不服说海冰不是陆冰,冰川。这两个报告都有了,海冰和陆冰都在增加.
    • 4. 全球范围内陆地上的冰川都在消失 +1
      Glaciers are retreating almost everywhere around the world ; including in the Alps, Himalayas, Andes, Rockies, Alaska and Africa.

    • 论坛上讨论的路子就是这样,自己要开始七嘴八舌了,第一件事要求观点不同方不要七嘴八舌,从来没见过谁说服谁
    • 5. 全球海平面在上个世纪上升了8英寸,在最近20年上升速度加倍 +1
      Global sea level rose about 8 inches in the last century. The rate in the last two decades, however, is nearly double that of the last century.
    • 加拿大在几百万年前还是亚热带气候。。。 +1
      • LOL 刚有地球的时候还全是熔岩呢,可惜没人类。 +2
        • 几十万年前到十万年前,全球都被冰冻,那个时候人类已经出现了,从人类出现后,全球一直就在变暖。。。这个难道真的是人类的功劳?
          • 人类的力量几何倍数的增长。量变成了质变。
            • 我倒是希望真的能有个质变,啥时候再把加拿大变成亚热带。。。 +1
    • 那你是希望变暖还是变冷一点?
    • 我觉得吧,关心一下加拿大,阻止恐怖分子难民进来,选一个川普一样的爱国者总理,要比什么狗屁南极冰川迫切的多;等选上了加拿大的川普,我和你一块治理全球变暖
    • 纵观以上回馈,好像没人反对地球正在变暖这个“事实”。 +3
      • 你的第三点早就站不住脚了,老猫.
        • 我不去追求细枝末节,研究文献万万千,有些分歧很正常。95%的事实match就足够了。 +1
          • 一个相反的结论你居然完全可以忽略,这种装睡的姿势连民科也做不到啊。
      • They may not even know what they have been talking about whatsoever. +1
    • 至于这个变暖是否是人类活动造成的,还是和人类活动相关但不完全是人造的,还是和人类活动完全无关,是分歧的焦点。还有就是这个变暖的后果有多严重,也有分歧。 +2
    • In the "short" history of human civilization, there were periods when the temperature was higher than now. Those were the time when civilization thrived.
      • 人类"有记录"以来最暖和的16个年份出现在2001年后。最暖和的一年是2016 - by NASA
        • Have you heard about 物候学?
        • 2017年还好,以前都是哈帕的错
