The study, conducted by Svante Björck, a climate researcher at Lund University in Sweden, steps back as far as it is possible to step to analyse with sufficient precision to compare modern developments. As a result, Björck's study has gone back a whole 14,000 years furtherthan any other study ever conducted.
"What is happening today is unique from a historical geological perspective," he says.
..."As long as we don't find any evidence for earlier climate changes leading to similar simultaneous effects on a global scale, we must see today's global warming as an exception caused by human influence on the earth's carbon cycle," says Björck. "This is a good example of how geological knowledge can be used to understand our world. It offers perspectives on how the earth functions without our direct influence and thus how and to what extent human activity affects the system."
