Ancient Global Warming Sees Troubling Spike
What started out as a moderate global warm-up about 55 million years ago triggered a massive injection of greenhouse gases into the atmosphere that sent temperatures skyrocketing, a new study says.
The finding suggests that today's temperature rise may just be priming the planet for a carbon belch of epic proportions.
"You've got these feedbacks, these chain reactions of events in the atmosphere-ocean system," said Appy Sluijs, a paleoecologist at Utrecht University in the Netherlands.
