Methane emissions can be traced back to Roman times

Emissions of the greenhouse gas methane into the atmosphere can be traced back thousands of years in the Greenland ice sheet. Using special analytical methods, researchers from the Centre for Ice and Climate, Niels Bohr Institute, among others, have determined how much methane originates from natural sources and how much is due to human activity.

The results go all the way back to Roman times and up to the present, where more than half of the emissions are now man-made. The results are published in the scientific journal, Natur.
