Doing Science at the Edge of the Earth

October 8, 2025

Key Takeaways Copied to clipboard!

  • The expedition to the northernmost landmass on Earth, Inuit Qeqertaat (Kaffeeklubben Island), aimed to establish a baseline record of plant life to track future changes driven by climate change. 
  • The journey was significantly complicated by unusually warm weather (nearly 60 degrees Fahrenheit the week prior), causing permafrost to thaw into boggy ground and melting ice to create wide rivers, turning an expected one-day hike into a three-day ordeal. 
  • The northernmost plant life discovered was ultimately an unnamed moss, found after an initial sighting of an Arctic poppy, highlighting that even the 'edge of the terrestrial world' supports life, which is now being documented for future comparison. 

Segments

Expedition Goal and Location

  • Key Takeaway: The expedition targeted the northernmost landmass on Earth, Inuit Qeqertaat (Kaffeeklubben Island), to study plant life in an under-surveyed Arctic region.
  • Summary: Scientists traveled to the northernmost landmass on Earth, a tiny gravel island in northern Greenland called Inuit Qeqertaat, also known as Kaffeeklubben Island. The primary goal was to survey plant life because this area is so remote that it has fundamental gaps in scientific understanding regarding climate change impacts. This ground-level data is necessary because satellite imagery cannot solve all problems in rapidly changing Arctic ecosystems.
Assembling the Expedition Team

  • Key Takeaway: The four-person team included an ecologist leader, a geophotographer/ecologist, an Indigenous Greenlandic archaeologist, and an NPR climate correspondent.
  • Summary: The traveling party assembled in northern Iceland and consisted of four members: ecologist Brian Buma, geophotographer and ecologist Jeff Kirby, Indigenous Greenlandic archaeologist Aka Simmonson, and NPR correspondent Alejandra Borunda. Borunda, a former climate scientist, was documenting the story while also assisting with the science. The initial phase involved recovering essential gear, including food and a small boat, that had been lost in transit.
Difficult Trek to the Island

  • Key Takeaway: Climate change directly hindered the final eight-mile trek by creating boggy, squishy permafrost and wide meltwater rivers, extending the journey from one day to three.
  • Summary: The final eight miles to the island, which was expected to be firm permafrost, proved extremely difficult due to recent high temperatures causing thawing. The team sank into boggy ground while carrying heavy packs and had to navigate wide rivers formed by melting snow and ice, which were not present on older maps. This challenging terrain ultimately took three days to cross instead of the anticipated one day.
Identifying Northernmost Flora

  • Key Takeaway: After spotting an Arctic poppy, the definitive northernmost plant on Earth was ultimately identified as an unnamed moss, located after a celebratory swim.
  • Summary: Upon reaching the island, the team initially spotted an electric yellow Arctic poppy, which was a contender for the northernmost plant. Further surveying led them to a different moss near a second poppy, which was initially declared the winner at latitude 88.665030 north. However, after a celebratory swim in the Arctic Ocean (the ‘Kaffeeklubben Swimmer’), the correspondent uncovered an even smaller patch of moss, which became the final confirmed northernmost plant.
Arctic Wildlife and Future Implications

  • Key Takeaway: The presence of more plant life than expected, alongside fearless wildlife like a stoat named Randall, confirms that rapid ecological change driven by Arctic warming is occurring even at the planet’s northern edge.
  • Summary: The expedition observed more plant life than anticipated, likely due to climate change making summer survival easier for flora. The team also encountered a small, unafraid stoat (a tiny weasel) they named Randall, which attempted to interact with the audio recorder. Cataloging the current state of life, including the poppies, mosses, and wildlife, establishes a crucial baseline for scientists to measure future ecological shifts in this rapidly warming region.
