Los primeros 10 a\u00f1os de este siglo fueron la d\u00e9cada m\u00e1s c\u00e1lida jam\u00e1s registrada. Es muy probable que esto provoque importantes cambios en el clima de Europa. Pero, \u00bfqu\u00e9 pasa en los casquetes polares? \u00bfSe est\u00e1 derritiendo el hielo? Si fuera as\u00ed, \u00bfqu\u00e9 efectos tendr\u00e1 en el clima global y el nivel del mar?<\/p>\n<\/div>\n<p>Un sat\u00e9lite europeo ofrece ahora algunas de las respuestas. El Cryosat, lanzado el 8 de abril de 2010, vuela sobre los polos a una altitud de 720 km.<\/p>\n<p>El Cryosat utiliza un instrumento de radar avanzado que mide cambios min\u00fasculos en el grosor del hielo mediante el rebote de se\u00f1ales de radio en la superficie y la captaci\u00f3n de los ecos. Si el eco regresa con mayor rapidez, indica que la superficie del hielo puede estar m\u00e1s elevada.<\/p>\n<p>El Cryosat tiene capacidad para detectar cambios de menos de 2 cm por a\u00f1o en la altura del hielo flotante del oc\u00e9ano \u00c1rtico. Al sobrevolar las enormes capas de hielo de la Ant\u00e1rtida puede medir cambios anuales de menos de 2 mm.<\/p>\n<p>Estos datos ayudar\u00e1n a los cient\u00edficos a determinar si el hielo del \u00c1rtico se est\u00e1 rompiendo y fundiendo. Tambi\u00e9n mostrar\u00e1n si las placas de hielo que cubren la Ant\u00e1rtida y sus mares est\u00e1n en regresi\u00f3n o en expansi\u00f3n.<\/p>\n<p>Esto es importante debido a que el nivel del mar puede elevarse varios metros si se fundieran las placas de hielo. Muchas ciudades y pa\u00edses que ocupan terrenos poco elevados pueden quedar anegados.<\/p>","protected":false},"excerpt":{"rendered":"<p>Most scientists agree that our planet is getting warmer.
