Bones in a cave inside the Arctic circle show that the world was hotter, the climate is always changing, and life adapts very well.

A special cave in far northern Norway has a a trove of thousands of old bones. They are deposited in layers that stretch back from 5,800 years ago to 13,000 years ago.  And it’s been a radical change: at the start, the cave was submerged under the ocean, so the bones are mostly marine species. But a few thousand years later the weather was warm, and birds and mammals had moved in. By 6,000 years ago the researchers estimate it was the hottest part of the Holocene and 1.5°–2.4°C warmer than the modern era of 1961–1990.

After that, the cave was blocked by scree, and the bone fragments sat there seemingly undisturbed for nearly 6,000 years while the ice sheets moved and the Vikings came and went and the world cooled. Then in 1993 someone happened to build a road nearby and found the cave. Now a team have analyzed the DNA in the layers and discovered that far from being an ecological disaster, when the Earth was hotter the Arctic must have been full of life. They found lemmings, shrews, voles, hares, geese, frogs, seals, and pheasants. They were also surprised to find dogs and cats there, even though there were no humans at the time (that we know of). The DNA test couldn’t distinguish whether these were our domesticated furry friends or their wild cousins. In any case, there were species that lived there then, that don’t live there now because it’s too cold.
