Now, however, researchers in California say they have found the first compelling evidence that it exists.
He and his colleagues showed the first compelling evidence of the response of the Earth's ozone layer to solar variability.
Extraterrestrial gases trapped within cagelike carbon molecules are providing the first compelling evidence that a meteor impact set off the most catastrophic of mass extinctions more than 250 million years ago, similar to the cataclysm that later killed off the dinosaurs.
