Expansion by Ice Data

Roughly one million years ago, the cycle of Earth’s ice ages suddenly shifted, with deeper and longer freezes occurring only every 100,000 years instead of once every 40,000 years. Really, nothing in our planet's orbit could explain the ‘abrupt' change, known as the Mid-Pleistocene transition (MPT), and with few other explanations, some hypothesized there must have been a long-term decline in atmospheric CO2 concentrations, cooling the planet to a new threshold.

1.5 million year old air bubbles trapped in the Antarctic ice sheet have now revealed a different picture. The data collected from minute air bubbles shows very low CO2. These are the first direct observations of atmospheric greenhouse gases before the ice ages on Earth began to grow longer, and they suggest something other than a long-term decline in CO2 was at play to shift our planet's entire ice age cycle.

What other pieces of information are hidden inside of the ice on this planet, as well as the planets in our solar system that could give us more insight into the history of our planet, neighboring planets, our species, and universe? What is to be discovered? What is the missing link to us and the first echoes of existence?
