La NASA confirma la reducción de la capa de hielo por el cambio climático

El Mundo, 10/03/2006 00:35 (CET)

EFE.- La NASA ha confirmado que Groenlandia y la Antártida pierden parte de su capa de hielo formada por agua dulce como resultado del actual calentamiento global, según un informe publicado en su sitio de internet, en el que señala que el análisis de imágenes captadas por satélites muestra que en ambos lugares ha ocurrido una pérdida neta de hielo entre 1992 y 2002, con un aumento correspondiente en el nivel marino.

En informes separados, la revista 'Science' ya había advertido en las últimas semanas de una reducción de la plataforma gélida de la Antártida y de que el deslizamiento de los glaciares de Groenlandia hacia el Atlántico se había acelerado en los últimos años.

Tanto la Antártida como Groenlandia son consideradas como las más importantes reservas de agua dulce del planeta. "Este nuevo estudio es el primero que realiza un inventario de la pérdida de hielo y de la caída de nieve en ambos de manera concreta e integral durante toda una década", destaca el informe.

Informe pionero

La NASA ha indicado que el estudio, publicado en la revista 'Journal of Glaciology', documenta por primera vez una extensa reducción en el grosor de la plataforma helada en la Antártida occidental, así como un aumento de la precipitación de nieve en el interior de Groenlandia. "Todos estos son signos del calentamiento climático pronosticado por los modelos informáticos", señala el texto. El estudio añade que una vez que se cuadraron la pérdida y la ganancia de hielo tanto de Groenlandia como de la Antártida se confirmó una pérdida neta de hielo que desembocó en el mar.

La cantidad total de agua vertida en los océanos (10.000 millones de toneladas) es equivalente al agua que se consume en los hogares y en los campos de los estados de Nueva York, Nueva Jersey y Virginia cada año, según el informe.

Sin embargo, Jay Zwally, científico del Centro Goddard de Vuelos Espaciales de la NASA, ha manifestado que la contribución del deshielo de las capas gélidas tanto de Groenlandia como de la Antártida al aumento del nivel oceánico durante una década ha sido menor de lo que se creía, apenas el 2% del reciente aumento de casi tres milímetros al año.

"Una mayor investigación mediante el uso de los satélites de la NASA y de otros datos reducirá la incertidumbre respecto a este importante problema", ha recalcado este científico.
