When Greenland was green: Ancient soil from beneath a mile of ice offers warnings for the future
Published: July 20, 2023 7.00pm BST
About 400,000 years ago, large parts of Greenland were ice-free. Scrubby tundra basked in the Sun’s rays on the island’s northwest highlands. Evidence suggests that a
forest of spruce trees, buzzing with insects, covered the southern part of Greenland. Global sea level was much higher then, between 20 and 40 feet
above today’s levels. Around the world, land that today is home to hundreds of millions of people was under water.
Scientists have known for awhile that the Greenland ice sheet had mostly disappeared at some point in the
past million years, but not precisely when.
In a new study in the
journal Science, we determined the date, using frozen soil
extracted during the Cold War from beneath a nearly mile-thick section of the Greenland ice sheet
The timing – about 416,000 years ago, with largely ice-free conditions lasting for as much as 14,000 years – is important. At that time, Earth and its
early humans were going through one of the longest interglacial periods since ice sheets first covered the high latitudes 2.5 million years ago.
The length, magnitude and effects of that natural warming can help us understand the Earth that modern humans are now creating for the future.
