Evidence that Earth is fine-tuned for human life continues to mount. Paleontologists have found fossil evidence on Ellesmere Island in northernmost Canada (78-83° N), dating back 4 million years, for plants, insects, and mammals that demonstrate winter and summer temperatures 27°F and 18°F above present ones, respectively. Such high temperatures would have greatly raised the sea level, redistributed rainfall patterns, and made the tropics unbearable. This discovery shows that the presently favorable conditions on Earth for widespread human civilization are more exceptional than once thought.
