Earlier this year, Lucas Jackson, a photographer with Reuters, joined a team of scientists affiliated with a NASA project named Oceans Melting Greenland (OMG) and traveled with them to the Greenland ice sheet and fjords. Jackson photographed the researchers as they set up their scientific equipment and took readings to help understand the ongoing impact of the melting glaciers, and map out what to expect in the future. Jackson says: “For both journalists and scientists, climate change is difficult to document. It most often happens imperceptibly—a tenth of a degree increase in temperature, a few less inches of rain, a slowly melting ice sheet.”
