Greene shares stories of extreme cold, frostbite, whiteouts and life above the tree line, as well as the moments of awe and resilience that define Arctic travel.As a Nova Scotia teacher and a new CanGeo Education board representative, Greene also brought the expedition into the classroom, connecting students to Canada’s North with live updates, weather tracking and daily Arctic haikus.Follow Greene on Instagram @greeneradventures (https://www.instagram.com/greeneradventures/)
