Los glaciares gigantes podrían exitinguirse pronto

Enormes glaciares como los de Groenlandia y la Antártida podrían extinguirse rápidamente, según un nuevo estudio sobre glaciares prehistóricos.

Un antiguo glaciar en el ártico canadiense se desvaneció rápidamente en tan sólo unos pocos cientos de años, según los nuevos descubrimientos realizados por paleoclimatólogos de la Universidad de Buffalo.

En caso de que, en la actualidad, se repitan las mismas condiciones, según lo expresaron los investigadores en un comunicado, “es muy posible” que esto se tradujiese en un fuerte aumento mundial del nivel del mar, lo que pondría en peligro a las poblaciones costeras.

“Muchos de los glaciares en la Antártida y en Groenlandia son de similares características al que estudiamos en el ártico canadiense”, dijo Jason Briner, profesor asistente de geología en la UB Facultad de Artes y Ciencias. “Basándonos en nuestras investigaciones, estos glaciares también podrían retraerse en un instante geológico”.

Los nuevos descubrimientos permitirán a los científicos predecir con mayor precisión cómo el calentamiento global afectará a las capas de hielo y el potencial de aumento del nivel del mar en el futuro, mediante el desarrollo más sólido clima y los modelos de láminas de hielo.

... Y no te olvides IMAGÍNATELO VERDE...
