Una importante y variada cantidad de hipótesis (astronómicas, geológicas, biológicas) atestiguan que el problema es complejo, y que podría ser multicausal. El tema del clima adquiere además un perfil dramático, dado que sabemos que sus alteraciones pueden ser rápidas, y que el hombre moderno ha surgido hacia el final de un periodo glacial que sospechamos que puede estar a punto de terminar.Efforts to understand cold climates began toward the end of 18th century, and they are still alive. During this time, a varied quantity of hypotheses from the astronomical, geological and biological fields have been put forward, which attest to a high-complexity, perhaps multi-causal topic. A topic with a dramatic profile, since we have learnt that climate can change very quickly, and modern man has appeared near the end of a glacial period which could well be very near its end.spajournal articlehttp://www.raco.cat/index.php/ECT/issue/archiveopen access551.583Ciencias de la TierraPaleoclimatologíaHistoria de la GeologíaEarth SciencesPalaeoclimatologyHistory of GeologyGeodinámica2507 Geofísica
