Anthropogenic CO2 increase is unprecedented

Today's anthropogenic CO₂ rise, however, is more than six times larger and almost ten times faster than previous jumps in the CO₂ concentration. This is the conclusion reached by a European research team led by the University of Bern. A new measurement technology developed at the University of Bern provides unique insights into the climate of the past. Previous CO₂ concentrations in the atmosphere could be reconstructed more accurately than ever before, thanks to high-resolution measurements made on an Antarctic ice core.
