The Arctic is warming at least twice as fast as anywhere else on the planet. All the vital signs—sea and land surface temperatures, terrestrial snow cover, the melting rate of the Greenland Ice Sheet, the extent and timing of sea ice—are all flashing red. The Arctic is Ground Zero of a rapidly warming, changing planet.

The National Oceanic and Atmospheric Administration, NOAA for short, recently issued its annual Arctic Report Card, which mostly makes for grim reading. At the same time, one of the storylines is that it’s not too late, that there is still time to slow and even to reverse the most pernicious changes that otherwise threaten all of us.

“What happens in the Arctic doesn’t stay in the Arctic,” says Tero Mustonen, one of the authors of the report. He knows the Arctic as a scientist, as a fisherman, as a leader of the innovative Snowchange Cooperative, as the head of the village of Selkie in North Karelia, Finland. And, as worried as he is by what he sees happening around him, he and his colleagues have developed a solution: rewild spoiled lands in the Far North to turn them back into the massive carbon sinks badly needed by Earth.

Listen as he explains the problem as well as the solution, with some geopolitics thrown into the mix to make matters worse. Then tell us: do you think climate change can be slowed in your lifetime?
