(Credit: Adam Jost) (CN) — Scientists announced a method Monday of determining the Earth’s temperature from the early Paleozoic era, allowing them to track the rise and fall of different species as the planet warmed and cooled. In a study published in the Proceedings of the National Academy of Sciences, geologists revealed they...
