The small town of Barrow, Alaska is perched on a point of land 320 miles above the Arctic Circle, where stark, flat tundra stretches in one direction and a vast expanse of Arctic Ocean extends to the horizon in the other. For most of the year a thick layer of sea ice covers this entire ocean. Even during the height of summer, a partial covering of ice remains, and the ocean temperature doesn’t rise above 35 degrees Fahrenheit. Despite these seemingly inhospitable conditions, tiny marine organisms thrive in this frigid environment.

Summers on the Norwegian archipelago of Svalbard are now warmer than at any other time in the last 1,800 years, including during medieval times when parts of the northern hemisphere were as hot as, or hotter, than today, according to a new study in the journal Geology.

A team led by Kevin Anchukaitis of the Lamont-Doherty Earth Observatory Tree Ring Lab is currently in Alaska’s Arctic National Wildlife Refuge, studying the effects of changing climate on trees. Ferried in by a bush pilot who landed on the tundra to drop them off, they are practically at treeline–the place where it is too far north for trees to grow. But there are still some spindly white spruces here, and they are taking cores from these, which can be used to measure weather of the past.
