Arctic limestone holds the key to climate change

Ikaite crystals found in Greenland and Antarctica could provide information about climate trends of the past, according to a Syracuse University Study.

These crystals trap information about temperatures at the time of formation, essentially making climate fossils.

This arctic limestone is another important indicator of climate history, allowing scientists to confirm climate trends of the past.

“We are extremely happy to figure out how to get a climate signal out of this peculiar mineral. A new proxy is always welcome when studying past climate changes,” said study leader Professor Zunli Lu.
