This September 21, 2018 aerial photo shows a couple posing for photographs at the Valley of the Blue Moon glacial lake fed by the Baishui Glacier No.1 atop the Jade Dragon Snow Mountain in the southern province of Yunnan in China. Scientists say the glacier is one of the fastest melting glaciers in the world due to climate change and its relative proximity to the Equator. (Photo by Sam McNeil/AP Photo)
