Rex Holwell, 47, poses for a photograph near a SmartBUOY, in Taktok, Nain, Newfoundland and Labrador, Canada, April 13, 2022. The buoy is filled with thermistors, which can be used to measure temperature and calculate sea ice thickness as part of the SmartICE program, which gives northern communities real-time measurements of sea thickness along their ice “highways” through a website, downloadable phone app or Facebook. “We have to adapt to climate change,” Holwell says. “We’re going to need more tools like SmartICE.” REUTERS/Melissa Renwick
