A dog team is pictured racing through pools of water that have formed on top of melting sea ice during an evening run outside of Iqaluit, Nunavut, Canada, in June 2022. Typically, from late December until June, much of the water in this area is frozen. But as temperatures rise, the snow covering the ice melts, creating large pools of water that reveal the turquoise-blue ice beneath it.
