El Nino is causing warmer and drier conditions in the Arctic, leading to record warm falls in Northern communities and challenging traditional hunting and trapping due to delayed ice formation.

The warming of the Arctic has caused a significant shift in the ecosystem of Great Slave Lake, with smaller diatoms replacing larger ones, potentially impacting the lake's productivity, carbon dynamics, food web, and nearby communities.

Samuel Roberts, 65, and Mark Elson, 51, said they were not prepared to be lost along the shore of Great Slave Lake when they headed out for a short fishing trip. But it became smoky and foggy, and the men became disoriented. The following day, when the air cleared, Roberts said they couldn't recognize anything. "We had no idea that we crossed over the Dettah side and [were] headed to the East Arm," said Elson.
