Do you know, the Arctic was extremely warm, unusually wet and ice-free 55 million years ago?! This is found by the ocean-floor sediment cores' new analysis, which was collected near the North Pole. This finding bolsters the prediction that massive amounts of greenhouse gases were released into the Earth's atmosphere.
