The Changelings' mission is to pool their collective vision and their interdisciplinary resources to help answer the most challenging questions about abrupt climate change; to catalyze new research and field work in basic science by leveraging paleoclimate insights to inform and guide current climate science, and to empower and mentor the next generation of climate scientists.
In 1999, NOAA’s Global Change program convened a group of scientists charging them with looking into the causes and future implications of the large abrupt climate global changes which punctuated glacial time. The idea was to bring together both people versed in the operation of the Earth’s atmosphere and ocean and people versed in the records kept in polar ice, ocean sediments, and mountain moraines.
The first meeting of this group took place in March 1999. Subsequent meetings were held in places where the group could observe glacial deposits representing the Last Glacial Maximum, the Younger Dryas, and the Little Ice Age.
When NOAA’s sponsorship closed in 2004, Gary Comer offered to "adopt" the group by hosting its meetings.
