Global sea level and Earth's climate are closely linked. Using speleothem encrustations from coastal caves on the island of Mallorca, we determined that western Mediterranean relative sea level was ~1 meter above modern sea level ~81,000 years ago during marine isotope stage (MIS) 5a. Although our findings seemingly conflict with the eustatic sea-level curve of far-field sites, they corroborate an alternative view that MIS 5a was at least as ice-free as the present, and they challenge the prevailing view of MIS 5 sea-level history and certain facets of ice-age theory.

Sea-level rises and falls as Earth's giant ice sheets shrink and grow. It has been thought that sea level around 81,000 years ago—well into the last glacial period—was 15 to 20 meters below that of today and, thus, that the ice sheets were more extensive. Dorale et al. (p. 860; see the Perspective by Edwards) now challenge this view. A speleothem that has been intermittently submerged in a cave on the island of Mallorca was dated to show that, historically, sea level was more than a meter above its present height. This data implies that temperatures were as high as or higher than now, even though the concentration of CO2 in the atmosphere was much lower.

Variabilidad natural de 1 metro y medio a 2 metros por siglo 
2 cm por año...... ¿y los 3 mm del IPCC? Eso significará que el deshielo se está deteniendo, ¿no? 

Pues hay científicos asombrados porque la Antártida no se está calentando, sino que se enfrió en las últimas tres décadas y media.

Pues lo que pasa con todos los modelos, son un reflejo de hasta qué punto entendemos un sistema, y obviamente el sistema climático no lo entendemos muy bien.


Edito para añadir:  Hrizzo, ese articulo que mencionas es de hace 8 años, un poco viejo en este campo.

claro que los modelos son una patata,

y más teniendo en cuenta que a nivel planetario hay un equilibrio radiativo mucho más complejo derivado de la rotación planetaria,

(añado, para que no penséis que estoy chalado  :

CitarThe equilibrium state of an isolated system is characterized by its conserved quantities. The total energy and particle number are usually taken into account in conventional thermodynamics, however, angular momentum is often overlooked. In the present paper, relativistic thermodynamics has been generalized to include angular momentum as a thermodynamical parameter. The resulting relativistic equilibrium has a remarkable difference from the one without angular momentum: a rotating body has a global temperature that is different from the local temperatures. Blackbody radiation from a rotating body is calculated as an example of applications of this global temperature

Carai como está el patio. Realmente fuertes las conclusiones. Ningún forzamiento es correcto. Si acaso solo el CO2, pero ni el metano, ni el sulfuro, nada se ha hecho bien. A tomar viento con los informes del IPCC. Ufff. ¿Servirá de algo?
Pues claro que si. Hay que despedir al Pachauri y poner a otro en su lugar para que puedan seguir ganando todos pasta. Y con  los nuevos datos elaboraran el superinforme apocalíptico destructivo necesario que diga que el enfriamiento global es culpa del calentamiento global, y así nos metan el impuesto de las narices y puedan hacer centrales nucleares libremente.  avergonzado

Pero si ese artículo es de la gente del GISS, y incluso lo firma Gavin Schmidt, uno de los autores de RealClimate  No tengo tiempo de leerlo, pero dudo bastante que esté en contra del calentamiento antropogénico ¿Por qué va en este topic? Me parece que muchos de los artículos que se citan aquí no tienen nada que ver con el título del topic...

Interglacials, Milankovitch Cycles, And Carbon Dioxide

Abstract
During interglacials, global temperature is also believed to be primarily controlled by carbon dioxide concentrations, modulated by internal processes such as the Pacific Decadal Oscillation and the North Atlantic Oscillation. Recent work challenges the
fundamental basis of these conceptions.

Summary
It has been shown above that low altitude cloud cover closely follows cosmic ray flux; that the galactic cosmic ray flux has the periodicities of the glacial/interglacial cycles; that a decrease in galactic cosmic ray flux was coincident with Termination II; and that the most likely initiator for Termination II was a consequent decrease in Earth's albedo.
The temperature of past interglacials was higher than today most likely as a consequence of a lower global albedo due to a decrease in galactic cosmic ray flux reaching the Earth's atmosphere. In addition, the galactic cosmic ray intensity exhibits a 100 kyr periodicity over the last 200 kyr that is in phase with the glacial terminations of this period. Carbon dioxide appears to play a very limited role in setting interglacial temperature.

Una pasada de artículo. Las glaciaciones se relacionan mejor con los cambios a largo plazo en el flujo de rayos cósmicos. Es decir, los rayos cósmicos o quizá la actividad magnética del Sol, una de dos. Un bombazo de artículo.
