The focus of carbon dioxide has elevated from about 280 parts per million to 350 elements per million, which is an increase of 25 per cent because the middle of last century. Nitrous oxide and different greenhouse gases additionally present comparable tendencies from analysis of the ice-core bubbles. The Law Dome ice core is at a location the place the snow accumulation is much greater than at Vostok.

For the deeper section of the core, totally different methods had been examined and
The dome fuji ice core df2021 chronology (0–207 kyr bp)
A glacial period is an interval of time (~100 thousand years) that’s marked by colder temperatures and glacier advance.. Interglacial periods are time intervals of warmer world temperatures (~10-20 thousand years) that separate glacial intervals. The Holocene is the present interglacial and it has persisted for the last ~11 thousand years. Comparison between ice core temperature reconstructions and ice core CO2 information revealed that glacial intervals (colder) coincided with decrease CO2 concentrations, while interglacial intervals (warmer) with greater CO2 concentrations.

Unveiling the anatomy of termination 3 using water and air isotopes within the dome c ice core, east antarctica
We need to emphasise that in our case the aim was not related to climate research as e.g. Mayewski et al. (Citation1996) and Wolff et al. (Citation2010), but simply to show that the mix of nitrate–liquid electrical conductivity measurements are useable for annual dating of an ice-core. The FTIR spectrometer described earlier was made out there at an early stage of optical isotope spectrometers. But the likelihood to 
include D/H measurements in the ice core studies, thanks to the early instrument developed, was extraordinarily useful and essential when tracing the nitrate focus in ice cores at very high time decision. The capacity to follow the annual variation in all three parameters provides an excellent quality control of the high-resolution information obtained from the whole record (122 m; 7776 samples) (Dreschhoff and Zeller, 1994).
