Multiple thermometry in Paleo Climate and Historic Climate
Abstract
The principle of isotope thermometry is that isotope ratios are temperature dependent. It is proposed that isotope ratios in bio-organic material may have independent temperature coefficients, so that by measuring ratios for several elements, e.g. hydrogen, carbon and oxygen, it may be possible to show that a temperature change occurred. Assuming that cellulose is formed almost at equilibrium, temperature coefficients for C, H and O are computed and found measurable size. The coefficients computed for C13/C12 and D/H agree to be of with measured values. Thus indications are that temperature changes in past climates may be measured in old tree rings, using this principle of multiple thermometers.
