The main purpose of this work is to present relative scales of temperature during holocene up to Ionian pleistocene using virtual reality.
Datasets used : GISP2 Ice Core Temperature and Accumulation Data, Law Dome Ice Core 2000-Year CO2, CH4, and N2O Data, EPICA Dome C Ice Core High Resolution Holocene and Transition CO2 Data, GISP2 Oxygen Isotope Data : Greenland Ice Core Project, Vostok Ice Core. Projects are researching values of CO2 in atmosphere using deep drills into sedimentary ice sheet layers corresponding to drill depth approx. to 3 km reaching 800 000 years back in time.

Law Dome Ice Core 2000-Year CO2, CH4, and N2O Data
Ice Core results: Law Dome CO2 and CH4 records of the last 1000 years first published in Etheridge et al., 1996 and 1998. Newer results which fill in gaps, extend record to 2000 BP and include N2O,
were published and explained in detail in MacFarling Meure et al. 2006 and MacFarling Meure 2004. Some new CH4 results were also published in Ferretti et al. 2005.
