El hielo se est\u00e1 convirtiendo en agua y fluyendo hacia los mares, lo que hace que suban sus niveles. Esto preocupa a mucha gente porque la subida del nivel del mar genera un mont\u00f3n de problemas, entre ellos, la inundaci\u00f3n de poblaciones y ciudades costeras de todo el mundo.<\/p>\n<\/div>\n<p>Los cient\u00edficos creen que ese hielo se est\u00e1 derritiendo a causa del cambio clim\u00e1tico. La Tierra se calienta y el calor funde el hielo. Las causas del cambio clim\u00e1tico son complicadas, pero se cree que las emisiones de gases de los coches y las f\u00e1bricas son, en parte, responsables.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1920\" data-credit=\"Planetary Visions\/CPOM\/UCL\/ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2016\/07\/CryoSat_has_been_measuring_the_thickness_of_ice\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2016\/07\/cryosat_has_been_measuring_the_thickness_of_ice\/17888542-2-eng-GB\/CryoSat_has_been_measuring_the_thickness_of_ice.jpg\" alt=\"CryoSat has been measuring the thickness of ice\"><\/figure>\n<p>CryoSat mide con mucha precisi\u00f3n la altura de los enormes glaciares de Groenlandia mediante un instrumento de alta tecnolog\u00eda llamado alt\u00edmetro radar. Cuando el sat\u00e9lite se encuentra sobre Groenlandia, este instrumento env\u00eda pulsos de energ\u00eda a la capa de hielo situada debajo. Esta energ\u00eda rebota en el hielo y regresa al alt\u00edmetro radar. Si se cronometra cu\u00e1nto tarda la energ\u00eda en volver al sat\u00e9lite, es posible calcular la altura del hielo. El sat\u00e9lite puede medir la zona de los bordes de las capas de hielo, que es donde se est\u00e1n produciendo m\u00e1s cambios.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1920\" data-credit=\"Library image\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2016\/07\/Ice_is_important_for_life_on_Earth_and_maintaining_a_healthy_climate\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2016\/07\/ice_is_important_for_life_on_earth_and_maintaining_a_healthy_climate\/17885693-2-eng-GB\/Ice_is_important_for_life_on_Earth_and_maintaining_a_healthy_climate.jpg\" alt=\"Ice is important for life on Earth and maintaining a healthy climate\"><\/figure>\n<p>CryoSat es un buen ejemplo de c\u00f3mo los sat\u00e9lites que orbitan la Tierra ayudan a vigilar nuestro planeta.
