Guangzhou snow has, this is this year early the big website, and micro-letter friends circle Shang most by concern of message one of, and Guangzhou this field new China established yilai first snow accompanied by of, is last year end of to this year early, national hundreds of a city minimum temperatures refresh history records, Beijing minimum temperatures-17 degrees, create 30 years to minimum; Hangzhou City below-9 degrees, almost 1969 years history minimum value...... Many people do not understand that this dramatic cooling associated with the Arctic continues to heat up. Not only that, the 2008 South China ice disaster, 2014 United States encounters the strong cold snap in 20 years, including frequent storms extreme weather in recent years in the northern hemisphere, can in fact be traced back to miles of the North Pole.

Scientists showed that under the influence of global warming, since 1979, Arctic sea ice extent is a declining trend, while the Arctic sea ice melts, the more, in the East of China, Korea and Japan more region with extremely cold winter weather. For now, the winter in Eastern Asia extreme weather and Arctic temperatures is most closely associated.

Change than in the Arctic sea-ice extent reduced. Scientists ' estimates, if distributed equally around 1990 the melting of Greenland's glaciers, every person on earth could probably get thousands of meltwater; but, 20 years later, this figure to 45,000 liters. It is clear that Arctic land ice is thawing fast.

Glacier melting has major coastal cities poses a direct threat to the world. According to the current rate estimates, by the end of this century, sea levels would rise by about 0.6 meters, like "India Ocean Pearl" Maldives, uniquely in the world, across the international date line, Kiribati Islands across the equator, is likely to disappear completely.

In addition, the barren Arctic tundra began to turn green from mosses, Lichen and Arctic tundra berry plants are gradually giving way to shrubs and boreal forests, and more and more began to appear once only found in warm regions of plant and animal in the Arctic; Overlord polar bears of the Arctic food chain, because of lack of sufficient food and started eating mice, reindeer and even their own kind. Scientists even fear changes in the living environment of the polar bears is much faster than the pace of adaptation.

However, accompanied by changes in the Arctic, but tiny little small temperature changes. Monitoring data show that from 1880 to 2012, the rise in global average temperatures of about 0.85, compared with the global average, Arctic warming increases more dramatically, that's about 2 ℃. But this looks small temperature changes, is the Arctic in recent decades that the direct cause of many changes.

Today, most scientists admit that does have an association between extreme weather and climate change and human activities, and plays a key role in global warming.

In December 2015, nearly 200 countries and regions in the world after difficult negotiations in Paris passed the milestone of the Paris agreements, control the rise in global average temperatures compared with pre-industrial levels within 2 ℃ or less reached a consensus. But the real challenge, far more complex than the agreement.

Ecosystem has its own huge inertia, once you reach a tipping point on climate change, even if the temperature is no longer continued to rise, climate change will happen on its own. If climate continues to warm, unmoved, then humanity will face no choice of the day. Disagreements can have debates can continue, but to protect our living planet, choose greener and greener way of life and development, has no doubt.

央视纪录片：广州年初降雪原因可追溯到北极|纪录片|北极_新闻资讯

　　原标题：如果不想失去选择的权利，请重视这貌似不起眼的温度变化！——《危险温度》与你我有关

　　广州下雪了，这是今年初各大网站、微信朋友圈上最受关注的消息之一，与广州这场新中国成立以来首次降雪相伴的，是去年底到今年初，全国数百个城市最低气温刷新历史记录，北京最低气温-17度，创30年来最低；杭州城区低于-9度，直逼1969年历史最低值……许多人并不了解，这次剧烈降温其实与北极持续升温有关。不仅如此，2008年中国南方冰灾、2014年美国遭遇20年来最强寒流，包括北半球近年来暴风雪极端天气频发，其实都可以追溯到万里之外的北极。

　　科学家研究证明，受全球气候变暖影响，自1979年以来，北极海冰的范围呈现逐年下降的态势，而北极地区的海冰融化的越多，在中国东部、韩国和日本地区遭遇的冬季极寒天气就越多。目前来看，亚洲东部地区冬季的极端天气与北极气温升高的联系是最紧密的。

　　发生在北极的变化当然不止是海冰范围缩小。科学家们的测算显示，如果平均分配1990年左右格陵兰冰川的融化量，地球上每个人大概可以获得几千升冰川融水；但是20年以后，这个数字变为了4.5万升。很显然，北极陆地冰川正在快速消融。

　　冰川融化已经给世界主要沿海城市造成了直接的威胁。按目前的速度测算，到本世纪末，海平面将上升大约0.6米，像“印度洋明珠”马尔代夫，世界上唯一地跨赤道、横跨国际日期变更线的基里巴斯等岛国，都可能完全消失。

　　此外，荒凉的北极苔原开始变绿，由苔藓、地衣和浆果植物构成的北极苔原正在逐步让位于灌木丛和北方森林；越来越多曾经只存在于温暖地带的动植物开始出现在北极；北极食物链的霸主北极熊，因为得不到充足的食物，开始吃老鼠、驯鹿、甚至是它们的同类。科学家甚至担心北极熊生活环境的变化，要远快于其适应环境的速度。

　　然而，与北极变化相伴的，却是微小到几乎不起眼的温度变化。监测数据显示，从1880年到2012年，全球平均气温大约上升了0.85℃，相比全球平均水平，北极地区升温的幅度要更显著，也就是大约2℃。但就是这看起来不起眼的温度变化，却是北极近几十年来这诸多剧变的直接原因。

　　时至今日，大多数科学家都承认，极端天气和气候变暖之间确实具有关联性，而人类活动，又在全球变暖中扮演着关键角色。

　　2015年12月，全球近200个国家和地区经过艰难地谈判，在巴黎通过了里程碑式的《巴黎协定》，就将全球平均气温较工业化前水平升高控制在2℃以内达成共识。但现实的挑战，远比达成协定要复杂得多。

　　生态系统有其固有的巨大惯性，气候变化一旦达到临界点，即便温度不再继续升高，气候变化也会自行发生。如果任由气候继续变暖而无动于衷，那么人类终有面临无可选择的境地的一天。分歧可以有，争论也可以继续，但要想守护我们赖以生存的地球，选择更环保、更绿色的生活和发展方式，已经无需置疑。

　　（财经频道八集电视纪录片《北极，北极！》，将于4月22日—4月29日每晚9点15分首播，当晚23点档，次日12点30分重播。）
