She is especially knowledgeable about climate change over the last few million years, including the history of Arctic sea ice, sea level, and western Arctic landscape change. She is currently engaged with the people of Mekoryuk and Kongiganak AK via the NSF Navigating the New Arctic Program and land scape change. She is also developing a community research plan for re-evaluating the tectonic and paleoceanographic history of the Arctic Beringian Gateway. She was Chair of the Polar Research Board of the US National Academy of Sciences (2014-2020) and is a Past-President of the American Geophysical Union Global Environmental Change section; and Past-President of the Quaternary Division of the Geological Society of America.

Julie Brigham-Grette, one of the scientists who contributed to the International Climate Crisis Initiative’s State of the Cryosphere 2024 report released today, says, “The sense of urgency couldn’t be higher … What’s more than ‘urgent?’ ‘Catastrophic?’ We’ve run out of ways to describe it.”

Geologist Julie Brigham-Grette admits she was “an extractive scientist” when she began studying ancient Arctic climates 4 decades ago. She’d fly into the region, collect data, and then return to the University of Massachusetts Amherst to write up her findings. “I might hire someone to take me along the coastline in their boat,” she says, “but I was never taught to involve the local people in anything I was doing.”

The continued rise in CO2 is unacceptable. This insanity cannot continue

Our message — the message of the cryosphere — is that this insanity cannot and must not continue. COP28 and this December must be when we correct course. Some degree of planetary-wide damage from cryosphere loss is already locked in. We must prevent even worse impacts from a collapsing cryosphere for each additional tenth of a degree temperature rise, especially past the “lower” Paris Agreement limit of 1.5°C.

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."
