The relative temperature (solid line) is represented as a proxy derived from 818-Oxygen isotopes from the Greenland Ice Sheet Project (GISP2).

Este procedimiento permite tambien su comparacion con las curvas de variacion de los isotopos del oxigeno ([18.sub.O]/[16.sub.O]) proporcionadas por los sondeos realizados en los hielos de Groenlandia GISP2 (Grootes et al., 1993; Meese et al., 1994; Sowers et al., 1993) y GRIP (Dansgaard et al., 1989 y 1993; GRIP members, 1993; Grootes et al., 1993; Johnsen et al., 1997), tanto de manera global (Fig.
La observacion de la curva de calibracion de las dataciones gravetienses y solutrenses de la mitad meridional de la Peninsula Iberica permite apreciar que los grandes cambios de probabilidad que describen las dataciones radiocarbonicas mantienen inflexiones que pueden ser correlacionadas tanto con cambios industriales de diferente escala --la sustitucion Gravetiense-Solutrense o la separacion en fases u horizontes de este ultimo complejo industrial--, como con los eventos paleoclimaticos reconocidos en las curvas de variacion de los isotopos del oxigeno obtenidas a partir de los testigos de los sondeos GISP2 y GRIP (Fig.
One possibility is that while temperatures were reduced by up to 2[degrees]C in the northern Hemisphere (Peteet 1995), the increased differentiation between northern and southern hemisphere polar ice volumes (Taylor Dome and GISP2 [[delta].sup.18]O records, Fig.
Comparison of the oxygen isotope records from the GISP2 and GRIP Greenland ice cores.
The glacioclimatological studies of the Greenland Ice Sheet Project 2 (GISP2) and other research have also shown that, while the LIA was generally characterized by periods of increased cold and glacial advance, it was not a period of spatially or temporally uniform cold (Bradley and Jones, 1993; Meese et al., 1994).
This record parallels the general climate trends established by analyses of the GISP2 cores from the Greenland ice sheet (Mayewski et al., 1994), the percent ice melt record of the Devon Ice Cap (Fisher and Koerner, 1994; Grumet, 1997; Koerner, 1997), and average annual temperature trends derived from Northern Hemisphere dendroclimatological studies (D'Arrigo and Jacoby, 1992).
