From “Reuters”:
Global warming and not a giant asteroid may have nearly wiped out life on Earth some 250 million years ago, an international team of scientists said on Thursday.It may be true, but there’s obviously reason to be skeptical. Very skeptical.The mass extinction, known as the “Great Dying,” extinguished 90 percent of sea life and nearly three-quarters of land-based plants and animals.
There has been recent evidence that a big asteroid or meteor hit the Earth and triggered the catastrophe, but researchers say they now have evidence that something much more long-term—global warming—was the culprit.
