"This was "Snowball Earth" – a deep freeze that began around 715 million years ago and held Earth in its icy grip for a good 120 million years. "There are no other comparable glacial periods on Earth. This one was really quite catastrophic," says Graham Shields of University College London in the UK."

To make the argument that scientist don't know... because the thermometer is on a few hundred years old and our weather data a bit more than a century, and in the same statement suggest that scientist know what happened millions of years ago and what the temperature at the equator was... you don't find a failing in the thought process of the statement?
