Synchronization of North Atlantic, North Pacific preceded warming, end of ice ageCorvallis OR (SPX) Jul 28, 2014 Scientists have long been concerned that global warming may push Earth's climate system across a "tipping point," where rapid melting of ice and further warming may become irreversible - a hotly debated scenario with an unclear picture of what this point of no return may look like. A newly published study by researchers at Oregon State University probed the geologic past to understand mechanisms of abrupt climate change. The study pinpoints the emergence of synchronized climate variability in the ... read more |
