As Earth’s climate changes, one of the hardest things to figure out is exactly how the planet will change in response. And while we can’t know the future for sure, we can get a lot of good clues from the past.

As Earth's climate changes, one of the hardest things to figure out is exactly how the planet will change in response; like how weather patterns will shift and how species may or may not adapt. And while we can't know the future for sure, we can get a lot of clues from the past.

Our planet has been through a lot of changes and understanding different chapters in its history can help us figure out what might be coming but most of those changes took place before anyone was around to record them, so it takes some serious detective work to figure out what the world was like back then. Fortunately scientists have some pretty cool tools that help them reconstruct the climate in the past.

One place scientists can look for clues is in a common mineral called Calcium Carbonate, which forms in lots of places and is especially common in the ocean. It is made of, well, calcium and carbonate ions and if conditions are right, this mineral can come together all by itself, crystals just form straight out of the water.
