Summer doesn't begin for two more days, but scientists are already sounding the alarm about dangerous ice melts going on right now in Greenland.

夏天还有两天就要开始了，但科学家们已经对格陵兰岛正在发生的危险冰融化发出了警报。

The vast island usually locks away enough fresh water in its ice sheet, which if melted can raise global sea levels by six meters.

这个巨大的岛屿通常会将足够多的淡水锁在冰盖中，如果冰盖融化，全球海平面将上升6米。

And research shows that in recent years its ice has melted faster than ever before.

研究表明，近年来，它的冰融化速度比以往任何时候都快。

This month, as temperatures in northwestern Greenland approach all-time highs, researchers are encountering unusual, surprising levels of melting ice in the region.

本月，随着格陵兰岛西北部的气温接近历史最高点，研究人员在该地区遇到了不同寻常的、令人惊讶的冰川融化水平。

The most significant concern here is how early this is all happening.

这里最重要的问题是这一切发生的时间有多早。

Greenland experiences annual ice melt and growth cycles.

格陵兰每年都会经历冰川融化和生长周期。

But this year, the melting season began in early May.

但今年，融化季节从5月初开始。

That's a month earlier than normal and something that's happened only once before in the historical record in 2016.

这比正常情况早了一个月，在2016年的历史记录中只发生过一次。

That means that not only is the ice melting very fast, it has more time to melt this summer than it would in a normal climate system.

这意味着，冰不仅融化得很快，而且今年夏天融化的时间比正常气候系统下的时间要长。

Longer melt seasons like this one seem to lead to much greater contributions to sea-level rise than in previous decades.

像这样较长的融化季节似乎比前几十年对海平面上升的贡献更大。
