Fudge ’02 Finds Climate Insight in Antarctic Ice Core (Nature)

Geologist T.J. Fudge ’02 is lead corresponding author on a new study published in Nature, which reveals that West Antarctica started warming up from the last ice age a few thousand years earlier than previously thought — an insight that could influence our understanding of climate change today.

Previous data from the East Antarctic Ice Sheet indicated that the chilly continent began to warm up 18,000 years ago, two millennia after the northern hemisphere started warming. But when Fudge and his team drilled out a two-mile-long ice core from the West Antarctic Ice Sheet on the other side of the continent, they found evidence of warming as early as 22,000 years ago.

“This means that Antarctica did not wait for a cue from the northern hemisphere to start warming,” Fudge said. “Instead, the warming started because the wobble in Earth’s orbit around the sun led to more sunlight reaching Antarctica and the Southern Ocean.”

    This is great work which proves that Bowdoin continues to be in the forefront of arctic exploration (first Peary, now Fudge!). Please pass along my compliments for his excellent work to TJ.
