Before making predictions, Troch and his collaborators looked back in time.

Troch and his collaborators got their hands on the sediment core and used it to validate and refine their model.

Troch and his colleagues found that increased snowfall would continue to protect the glaciers from melt if regional warming was curbed at 1.5 degrees celsius above turn-of-the-century levels.

"The study underscores the need for deep emission cuts to protect glaciers, which is vital to limit global sea-level rise," Troch said.

"This could push glaciers into a new regime dominated by rain rather than snowfall," Troch explained.
