Then there are the anthropological insights that such ice cores provide, like those extracted out of Mount Kilimanjaro. These ice cores are taken from ice sheets and glaciers by drilling into frosty locations across the world, from the polar regions to the tropics. This is done manually or with advanced technology. With the capacity of drilling technology able to reach depths of two miles into the ice, it comes as no surprise if components dated at nearly one million years old are being uncovered!

Core Of The Problem
What is it about these ice cores which is so telling when it comes to the big questions? Interestingly, there are plenty of glaciers and ice fields that crept along for more than a thousand years, gathering more and more ice as they moved, creating a layered climate change record. Let’s look at the actual bubbles frozen in time which contain air formed from the era they were created. Such samples, when tested in lab conditions, can reveal just how much carbon dioxide was present within the atmosphere throughout such an epoch.
