Behind the flood: global average surface air temperature in China twice times

"This year's strong El Ni?o led to the aftermath of storm-prone. I work for more than 30 years, today's storm was the biggest rain I've ever seen. "On July 6, at a press conference held in the Wuhan flood control headquarters, drainage of the Wuhan water Bureau official said.


Hubei, Anhui and other places appear in the short term, continuous rainfall in the past are not common, Super El Nino weather conditions helped push one of the culprits of the flood.


Compared with the previous El Ni?o events, the event was combined with the "super" Word. According to statistics, since 1951, some 2/3 century, strong El Ni?o events have happened 3 times.


In this regard, the World Wildlife Fund's global climate change programme director Yang said in an interview with the business daily journalist, climate change will exacerbate climate change, flooding more large and occur more frequently than previously. Not just in China, many countries around the world have suffered the vagaries of weather problems.


El Nino intensity unprecedented


"(The Chinese) serious flood situation is mainly caused by strong El Ni?o events. "Yang said.


El Nino refers to the Eastern Pacific and Central seawater temperature anomalies in the tropical oceans continue to warm, so that changes in the world climate patterns, causing droughts in some areas while other areas of excessive rainfall anomaly.


Journalist access to relevant information found in 2014 until May this year before this super strong El Nino event, more than half a century only had 2 Super El Nino events, namely 1982/1983 and 1997/1998 El Ni?o events. The event lasted much longer than the previous two, and the sea temperature is higher than the annual total value of 21.5, 23.1 and 26.9 ℃, showed an increasing trend.


Nest cleaning, Deputy Director of national climate Center said this El Nino event duration period, the total intensity, peak strength, the three indicators have reached a record, also is likely to be the strongest El Ni?o events since the 20th century.


Our climate warms too fast


In recent years, the "urban beach" staged this poking fun at almost every year in the us, behind mapping the distribution of meteorological disasters in recent years in China.


Suffered flood disasters in the South, the North is also severely affected by El Ni?o. Reporters found that the liaoshen evening news reported on July 7, said, "affected by the El Ni?o effect, weekend temperatures reached 34 degrees, distance of maximum temperatures of 35 degrees over the same period in the history of Shenyang only once away. ”


Reporters found that the China Meteorological Administration released by the official website of the 2015 main meteorological disasters and characteristics referred to in: "rainstorm in flood season of the South, torrential rains caused some rivers rising, waterlogging in farmland in Shanghai, Shenzhen, Wuhan and other cities experiencing serious water logging. Main stage drought in parts of the North, Hebei, Shanxi, Inner Mongolia, Liaoning, Gansu, Shaanxi, and other periodic drought is heavy. ”


Yang said in an interview with the business daily journalist, earlier this year out the cold winter in many parts of the world, global climate change will be the exception. "If there is no climate change can't be so bad that climate change played a role in stacking. Global average temperatures and higher, rising trends are becoming evident. ”


May 4, 2015 published by the party School of the CPC Central Committee issued the attached great importance to the newspaper study times, climate security and vigorously promoting the construction of ecological civilization, published an interview of China Meteorological Administration, Zheng guoguang, a record. Zheng guoguang said, significantly higher than the global climate warming. Nearly 60 years, the national average temperature rise 1.38, 0.23 c every 10 years on average, almost twice times the global average.


Yang said that problem is posed by climate change, do not need water when the water came, but when they need to seed the water but not water. In fact, this does not mean that the annual amount of rainfall will be very big changes, just let people find weather more changeable.


Late last year, the 21st session of the United Nations climate change conference, held in Paris, the results achieved are still limited. Yang said at the session of the United Nations Climate Conference, to solve the problem of global climate change, you also need to work together around the world.

洪灾背后:中国地表气温升幅接近全球水平两倍

  “今年超强厄尔尼诺的余波导致暴雨频发。我从事工作30多年,今天的暴雨是我见过的最大的一场雨。”7月6日,在武汉市防汛指挥部举行的新闻发布会上,武汉市水务局排水处相关负责人如是说。


  湖北、安徽等地短期内出现大量、持续降雨,在过去并不常见,超强厄尔尼诺的气象条件是助推此次汛情的元凶之一。


  与此前的厄尔尼诺相比,此次的事件被加上了“超强”二字。据统计,从1951年以来大约2/3个世纪里,超强厄尔尼诺事件一共也就发生过3次。


  对此,世界自然基金会全球气候变化应对计划主任杨富强在接受《每日经济新闻》记者采访时表示,气候变化会加剧气象变化,使洪水比此前更大、发生频率更高。不仅仅是中国,全球很多国家都遭遇过这种气象变化无常的问题。


  厄尔尼诺强度史无前例


  “(此次中国出现的)严重汛情主要是超强厄尔尼诺事件引起的。”杨富强说。


  厄尔尼诺主要指太平洋东部和中部的热带海洋海水温度异常地持续变暖,使整个世界气候模式发生变化,造成一些地区干旱而另一些地区则降雨量过多的反常现象。


  记者查阅相关资料发现,在2014年持续至今年5月的这次超强厄尔尼诺事件之前,大半个世纪里全球仅发生过2次超强厄尔尼诺事件,即1982/1983年和1997/ 1998年厄尔尼诺事件。但本次事件持续的时间远远长于前两次,而海温比常年偏高的累计值为21.5℃、23.1℃和26.9℃,呈递增趋势。


  国家气候中心副主任巢清尘称,本次厄尔尼诺事件持续时间周期、累计强度、峰值强度这三个指标均达到了历史最高,也很有可能成为20世纪以来最强的厄尔尼诺事件。


  我国气候变暖速度过快


  近年来,“城市看海”这样的调侃几乎每年都会在我们身边上演,背后也映射出了我国近几年气象灾害的大致分布规律。


  就在南方遭遇洪涝灾害时,北方同样也受到厄尔尼诺的严重影响。记者发现,《辽沈晚报》在7月7日的报道中提到:“受到厄尔尼诺影响,周末最高温将达到34度,距离沈阳历史上同期最高温度35度仅一度之遥。”


  记者发现,中国气象局官网上公布的《2015年主要气象灾害及特征》中提到:“南方汛期暴雨过程多,暴雨造成部分江河水位上涨,农田渍涝,上海、深圳、武汉等多个大中城市发生严重内涝。而北方部分地区主要出现阶段性干旱,河北、山西、内蒙古、辽宁、甘肃、陕西等地阶段性干旱较重。”


  杨富强在接受《每日经济新闻》记者采访时表示,今年初全球很多地方都出现了最冷冬天,全球气候变化会把这种异常加剧。“如果没有气候变化不可能那么厉害,气候变化起到了叠加的作用。现在全球平均温度越来越高,上升的趋势越来越明显。”


  2015年5月4日出版的中共中央党校机关报《学习时报》发文《高度重视气候安全 大力推进生态文明建设》,刊登了中国气象局局长郑国光接受采访的记录。郑国光指出,我国气候变暖的幅度明显高于全球。近60年来,全国地表平均气温升高1.38℃,平均每10年升高0.23℃,几乎是全球平均升幅的两倍。


  杨富强表示,气候变化带来的问题就是,不需要水的时候水来了,但需要来水进行播种的时候,反而不来水了。实际上,这并不意味着全年的降雨总量会有很大变化,只是让人觉得气象更加变化无常。


  去年底,第21届联合国气候变化大会在巴黎召开,所取得的成果依然有限。参加多届联合国气候大会的杨富强表示,要解决全球气候变化的问题,还需要全世界共同努力。
