南极的林德斯岛(Galindez Island)被科学家拍到，原本应该是一片纯白雪的大地，竟然变成一片如血染过的红，大量极地雪藻存在证明气候变迁，令人担忧。

海洋生态学家佐托夫(Andrey Zotov)拍下了长年白雪覆盖的南极，变成了一片血红的惊人画面。他将照片上传到脸书，经过显微镜鉴定，发现这片血红是“极地雪藻”在迅速增生产生的景象。这些生物会在冬天冬眠，当阳光变多、雪地出现液态水就会吸收水分，苏醒并且快速繁殖。

幼期的极地雪藻因有叶绿素，因此会呈显绿色，后来会因为含有类胡萝卜素以及虾青素而逐渐转为橘红色，它们有细胞壁能抵挡紫外线的辐射，也能吸收能量融化更多雪，这能证明南极气温比以前来得更高，也显示了暖化日趋严重。

科学家研究指出，融冰出现多的地方藻类会大幅增加，而藻类多的地方又会让雪融得更快，会出现大量极地藻类，等于该地的气温变高，2月13日探测器附近的西摩岛达到破纪录的20.75度高温，这也是南极洲第一次单日破20度，情况令人担忧。
