Abstract
The sizes of major sources and sinks of atmospheric methane (CH4), an important greenhouse gas, are poorly known, CH4 from north Siberian la kes contributes similar to 1.5 teragrams CH4 year(-1) to observed wint er increases in atmospheric CH4 concentration at high northern latitud es, CH4 emitted from these lakes in winter had a radiocarbon age of 27 ,200 years and was derived largely from Pleistocene-aged carbon.
