基本解释

英国海岸护卫队后来猜测，那次来自“北冰洋”号的常规通讯可能来自劫匪，或者是船员在胁迫下完成的。
She and other scientists are researching whether there might be a ‘tipping point’ for Arctic sea ice –a point at which sea ice will disappear and never recover, even if the climate cools.
她与同事致力于研究对于北冰洋上的海冰是否存在一个不可逆转的“消融点”，一旦达到该点即使气候转凉海冰也无法恢复原来的覆盖量。
They do not have a set migration pattern, unlike some other whale species - which raises questions about how they may adapt in future, if the projected declines in summer Arctic sea ice materialise.

One of the scientists says the past six years have shown the lowest Arctic sea ice cover ever measured.
The center says September Arctic sea ice is decreasing at a rate of more than eleven percent every ten years.
The amount of ice cover and its thickness are two measures of the health of the Arctic Sea.

And retreating Arctic sea ice provides even more visible data to support conclusions of warming.
