[:ja]大西宇宙飛行士がISSから撮影したイランのウルミア湖を見ると、藻の大量発生で赤色に変色しています。4月と7月の3ヶ月間の変化を見ると、湖が縮小しているのもわかります。
季節変動の要素もありますが、地球温暖化、ダムの建設、地下水の過剰利用といった複合要因で干上がりつつあると伝えられています。NASA ClimateやNational Geographic誌が非常にわかりやすい画像比較を掲載しています。

[Earthview Wonders] No.57: Lake Urmia of Iran
Lake Urmia of Iran captured from ISS. Mass generation of algae and bacteria has turned the lake from green to red in 3 months.
Credit: Takuya Onishi, JAXAThe lake presumably shinks its size due to global warming, construction of dam, overusage of underground water in addition to seasonal fluctuation. NASA Climate and National Geographic provides a comprehensive photo comparison.
