MIAMI, April 5 (Reuters) - The Nobel Prize-winning scientist who rang the first alarm bells over the ozone hole issued a warming about climate change on Saturday, saying there could be "almost irreversible consequences" if the Earth warmed 2.5 degrees Celsius (4.5 degrees F) above what it ought to be."Things are changing and there's no doubt that it's as a result of human activities," said Mario Molina, a Mexican who shared a Nobel prize in chemistry in 1995 for groundbreaking work on chlorofluorocarbon gases and their threat to the Earth's ozone layer.
"Long before we run out of oil, we will run out of atmosphere," he said.
Molina told a panel discussion on climate change at an annual Inter-American Development Bank meeting in Miami that the increasing intensity of hurricanes was among the worrisome changes that scientists had linked to a rapid global warming trend over the past 30 years. More >>>
