A polar bear whose bottom half is caked in oily black gunk. A whale wrapped in striped fabric: a pseudo straightjacket. These are the messes climate change leaves behind, the things we know are happening but often don’t have the opportunity to see with our own eyes. Swiss street art duo Christian Rebecchi and Pablo Togni, otherwise known as NeverCrew, met in art school when they were 15 and started making work together soon after.

“These are the stunning shots of one photographer who is putting everyday “selfies” to shame. Paul Zizka, 34, began experimenting with night photography just two years ago and immediately became fascinated with the spectacular scenes he discovered.
