A shrine maiden walks in the snow at the Tsurugaoka Hachimangu Shrine in Kamakura, near Tokyo, Thursday, November 24, 2016.

Above-freezing temperatures kept the snow from sticking, but forecasters said there could be an accumulation of up to 2 centimeters (1 inch). The last time it snowed in central Tokyo in November was in 1962. (Photo by Shizuo Kambayashi/AP Photo)

The Greenland ice sheet is a vast body of ice covering 660,235 sq miles, roughly 80% of the surface of Greenland. It is the second largest ice body in the world, after the Antarctic Ice Sheet. Some scientists predict that climate change may be near a "tipping point" where the entire ice sheet will melt in about 2000 years. If the entire 2,850,000 cubic kilometres (683,751 cu mi) of ice were to melt, it would lead to a global sea level rise of 7.2 m (23.6 ft).

In the desert near Joshua Tree, California, there stands a 70-year-old homestead cabin that isn’t all there. The ethereal cabin is part of an outdoor art installation by artist Phillip K. Smith III called Lucid Homestead. To give the cabin its striking appearance, the artist replaced strips of the wall with mirrors and the windows with mirrored panels that light up at night. The building reflects the desert sun and environment around it, making it seem like an airy and transparent space
