摘要
第一次进入北极格陵兰地区考察,笔者密切关注全球气候变暖对北极格陵兰冰雪的影响,格陵兰西海岸和斯瓦尔巴德群岛自然环境的异同。考察研究表明,全球气候变暖对北极格陵兰冰盖西部影响很大:冰盖融化形成的天蓝色冰湖比比皆是,冰川退缩显著,在峡湾中的冰川退缩后形成了奇特的冰山群。这些现象警示我们,在全球变暖的大背景下,人类一定要自律,尽量减少排放各种温室气体,切忌火上浇油,尽可能地为人类应变气候灾变赢得时间。另外,北极格陵兰西海岸和北极斯瓦尔巴德群岛的自然环境相似,由于受海洋暖流的影响,在冰雪世界中镶嵌着色彩缤纷的绿洲。
It has been paid more attention to the influence of global warming on the ice and snow in Greenland of Arctic and comparison of the natural environment between the Greenland of Arctic and Svalbard during my first scientific expedition time in Greenland.It show us from the scientific expedition that there is a strong influence of global warming on the ice and snow in the west part of Greenland in Arctic.Such as,there are the sky blue lakes on the ice sheet of west Greenland everywhere,the glacial recession is very obvious and there are many icebergs in the Ilulissat Fjord.It is warning us from the above that under the background of the global warming mankind must be bound by ourselves to get the time for preparing against possible emergence,such as more decrease of discharging the greenhouse gases.On the other hand,there is a similar natural environment with the oasis in the region of ice and snow both in the regions of the Svalbard and the west seacoast of Greenland as the effect of warm oceanic general circulation.
