Chronology of Geologic Systems
Julie Brigham-Grette is an internationally-renowned expert on climate evolution in the Arctic. She is a frequent contributor to media reports including in Science magazine, PBS, NPR and the CBC.
Since 1991, she has participated in nine field expeditions to remote regions of Arctic Russia and I was co-chief scientist in 2002 of an expedition on the U.S. Coast Guard icebreaker Healy, taking sediment cores from the Bering and Chukchi Seas. Brigham-Grette is the US Chief Scientist of the El’gygytgyn Lake Scientific Drilling project, a $10M multinational field program leading to the first unprecedented recovery in 2009 of a 3.6 Myr record of paleoclimate from the terrestrial Arctic.

“The overall picture is mixed,” says Julie Brigham-Grette, a geologist at the University of Massachusetts in Amherst. “We’re opening up an entire environment that has otherwise been cut off from human influence.”
Melting Ice, Raging Fires: Summer In The Arctic, Courtesy Of Climate Change
In the Arctic, a warming planet is accelerating the loss of sea ice and raising the stakes for the region. Julie Brigham-Grette joins two other scientists in a discussion.
New Arctic Science Cooperation Agreement Comes into Force

“This agreement is extremely important to foster scientific collaboration among all Arctic nations, as we are witnessing the rapid transition of the entire Arctic system due to climate change. The massive loss of summer sea ice and the reality of ice-free Arctic summers perhaps only 10 years from now [are] an international game changer,” Brigham-Grette, a professor in the Department of Geosciences at the University of Massachusetts Amherst, told Eos. “The sea ice is changing, commercial fisheries are migrating, the permafrost is thawing, shipping routes are changing, etc. As the Arctic opens up to new challenges and opportunities, we need to collectively manage and share responsibilities for what humans do to the Arctic. Honestly, we cannot screw this up!”
Antarctica is headed for a climate tipping point by 2060, with catastrophic melting if carbon emissions aren’t cut quicklyThe Conversation

Julie Brigham-Grette writes: "New research shows it is Antarctica that may force a reckoning between the choices countries make today about greenhouse gas emissions and the future survival of their coastlines and coastal cities, from New York to Shanghai."
