Sea-ice extent in August was also extremely low, second only to August 2007 (Fig. 1).
八月份的海冰范围也非常小，仅高于2007年八月的水平。
They show Arctic sea ice extent for the September 2009 minimum (left) and March 2010 maximum (right).
它显示的是北极海洋结冰程度在2009年9月的最低值(左)和2010年3月的最高值(右)。
The Arctic sea ice extent averaged for July was the second lowest in the satellite record, after 2007.

On July 1, 2010, NSIDC reported that Arctic sea ice extent had continued its rapid decline through the month of June.
2010年7月1日，国家冰雪数据中心报道，北极海冰面积自6月份起一直在急剧下降。
But in 2008, Arctic sea ice extent was the second-lowest on record, with losses particularly acute in the Beaufort sea.
但是2008年是北冰洋海冰面积有记录以来倒数第二小的年头，波弗特海地区海冰面积更是锐减得厉害。
In other words, even as Arctic climate continues to warm over the long-term, there won't be a new record low ice extent each year.
换句话说，即使北极的气候长时间在持续变暖，也并不会出现每年都会出现更低的海冰范围记录。
They blame the loss on global warming, which has driven temperatures in the Arctic to record highs and summer ice extent to recent lows.
他们将这一现状归咎于全球气候变暖，这令北极圈的气温达到了历史新高，而夏天冰盖的范围则跌到了历史新低。
The ice extent has been tracked by the us National Snow and ice Data Center (NSIDC) in Boulder, Colorado, using satellite measurements.
位于美国科罗拉多州博尔德的国家冰雪数据中心(NSIDC)一直在监测北极冰面面积，利用卫星来进行丈量。
Warm waters passing through the strait into the Arctic Ocean might have helped reduce sea ice extent since the turn of the twenty-first century.
自从新世纪开始，通过白令海峡进入北冰洋的温暖海水，已经开始限制海冰的范围。
As a result, sea ice extent for the Arctic actually peaked on March 31, 2010-the latest peak of wintertime Arctic sea ice extent in the satellite record.
结果导致2010年北极的海冰范围是在3月31日达到峰值——这是有卫星记录以来北极海冰范围最晚的冬季峰值。
The figure shows in red the years with the five lowest values of sea-ice extent for a certain month and in blue the years with the five highest values.
在图中，红色表示在该月份时海冰范围最小的五个年份，蓝色表示在该月份时海冰范围最大的五个年份。
That this is not the case becomes obvious from the graphical distribution of extreme sea-ice extent for each individual month that is shown in Figure 2.
从图表2中展示的各月海冰范围极值的图像分布来看，情况显然不是这样。
The maps were made by combining satellite measurements of snow and ice extent with calculations of the amount of sunlight reaching the ground during the season.
利用卫星测量冰雪范围，并计算出照射地面的日光值，最后绘制出上面的图像。
The years with the five lowest values of sea ice extent for a certain month are marked in red, those with the five highest values of sea-ice extent are marked in blue.
在特定月份海冰范围最小的五个年份用红色标示，最大的五个年份用蓝色标示。
The Arctic sea ice extent averaged for July was the second lowest in the satellite record, after 2007, to the latest figures from the National Snow and Ice Data Center (NSIDC).
根据来自国家冰雪数据中心（NSIDC）的最新数字，7月份平均北极海冰面积为2007年后卫星纪录中第2个最低点。
Hence, sea ice extent is primarily defined by the prevailing climate conditions; the ice-albedo feedback mechanism is, in isolation, too weak to stabilize a very low sea-ice cover.
由此可见，海冰范围首先由占主导地位的气候状况决定；单独来看，冰反射反馈机制的影响太过微弱，无法长期保持极低水平的海冰覆盖。
The results point out that the sea ice extent oscillations on the west and east sides of Greenland island show inverse variation with distinct interannual and interdecadal circles.
结果表明，格陵兰岛东西两侧海冰面积呈显著反相变化，并且具有明显的年际和年代际周期性振荡。
The IPCC's computer models had simulated an average loss of 2.5% in sea ice extent per decade from 1953 to 2006. But in reality the Arctic sea ice had declined at a rate of about 7.8% per decade.
IPCC的电脑模拟显示:从1953年到2006年期间北极海冰的平均熔化速度为每十年2.5%.但实际上却是7.8%.
