Today, researchers are able to extract vast amounts of information using current methods — such as precise digital measurement and categorization of the bones, examination of the conditions in which the bone fragments were preserved, as well as isotopic and genetic analysis.
Just as radiocarbon dating can place a substance in time, isotopic analysis can also pinpoint its location.
Isotopic analysis is used in a variety of fields across the sciences, such as Geology, Biology, Organic Chemistry, and Ecology.
Because carbon cycle processes such as photosynthesis fractionate the heavy isotope 13C from the lighter 12C, isotopic analysis can usually be used to «trace» sources and sinks of carbon.
It is appropriate as this point to add that if Bolin & Eriksson's conditions in the last paragraph were true, carbonated beer (Bohren, 1987) and soda «pop» as we know it would be an impossibility with their «buffer» factor (see below); rain and fresh water would not show the observed equilibrium pH of 5.7 (Krauskopf, 1979); and experiments would not had shown complete isotopic equilibrium between CO2 and water in just hours, which in turn is the prerequisite for routine stable isotope analysis involving CO2 (Gonfiantini, 1981).
However, both the driving force and the climate reconstructions over the pre-industrial era are based on the analysis of the natural archives of climate sensitive quantities, such as the growth of trees and seashells, and the changes of chemical, biological, and isotopic compositions in lake sediments and ice core samples.

Oakwood, the tragedy is not what's happening in science — things there are just as they should be: the field continues to develop new data and refined analyses, general conclusions have been reached that a very large majority support, based on well - established principles (properties of CO2, thermodynamics, effects of warmer air on evaporation...) and data (measures of CO2 levels, shifts in isotopic composition of atmospheric CO2, temperature records — instrumental and proxy,...).
