Thanks for the link. Aside from the OP article's basic regurgitation of prior (perhaps stale - I couldn't read it either being behind a "sign-in wall"), the Smithsonian author clearly didn't view it as a race against time and human-induced climate change, but merely an unexpected windfall for researchers:

"There are countless negative impacts of the changing climate, but the recovery of these artifacts could be an unexpected positive. Our uncertain climate future may inadvertently help researchers learn more about our past."
