Explorer's Greenland snowkite traverse and Swiss glacier retreat highlight climate-driven terrain change

Hong Kong explorer Wilson Cheung completed a 1,700km scientific snowkite traverse across Greenland in 2026, collecting data on the ice sheet. During a subsequent Swiss Alps field trip with students, he found previously accessible terrain destabilized by glacier melt and thawing ground, with rockfall increasing fieldwork hazards. The contrast underscores accelerating cryospheric change and its practical impacts on access and safety.
