Troubling scenes from an Arctic in full-tilt crisis

The Arctic island of Svalbard is so reliably frigid that humanity bet its future on the place. Since 2008, the Svalbard Global Seed Vault — set deep in frozen soil known as permafrost — has accepted nearly 1.4 million samples of more than 6,000 species of critical crops. But, the island is warming six to seven times faster than the rest of the planet, making even winters freakishly hot, at least by Arctic standards. Indeed, in 2017, an access tunnel to the vault flooded as permafrost melted, though the seeds weren’t impacted.

This February, a team of scientists was working on Svalbard when irony took hold. Drilling into the soil, they gathered samples of bacteria that proliferate when the ground thaws. These microbes munch on organic matter and burp methane, an extremely potent greenhouse gas and significant driver of global warming. Those emissions are potentially fueling a feedback loop in the Arctic: As more soil thaws, more methane is released, leading to more thawing and more methane, and on and on.

In some parts of Svalbard, though, the scientists didn’t need to drill. Air temperatures climbed above freezing for 14 of the 28 days of February, reaching 40 degrees Fahrenheit, when the average temperature at this time of year is 5 degrees. Snow vanished in places, leaving huge pools of water. “I brought my equipment to drill into frozen soil and then ended up sampling a lot of soil just with a spoon, like it was soft ice cream,” said Donato Giovannelli, a geomicrobiologist at the University of Naples Federico II and co-lead author of a paper describing the experience, published last week in the journal Nature Communications. “That was really pretty shocking.”…

The speed of transformation in the Arctic is shocking, even for stoic scientists. And as nations keep spewing greenhouse gases, the feedback loops of the far north are threatening to load the atmosphere with still more methane. “We call this the new Arctic — this is not something that is a one-off,” Giovannelli said. “And on the other side, we’ve probably been a bit too cautious with our warnings regarding the climate. It’s not something for the next generation. It’s something for our generation.”
