Elle n'est ni trop chaude ni trop froide. C'est pourquoi notre plan\u00e8te est le seul endroit que nous connaissons o\u00f9 l'eau peut se pr\u00e9senter sous forme de gaz, de liquide ou de solide (glace).<\/p>\n<\/div>\n<p>Nous rencontrons assez souvent de la glace en hiver, mais elle existe toute l'ann\u00e9e aux p\u00f4les et au sommet des hautes montagnes.<\/p>\n<p>Les calottes glaci\u00e8res et les glaciers dans les montagnes grossissent ou r\u00e9tr\u00e9cissent assez souvent. A l\u2019heure actuelle, beaucoup de scientifiques pensent que le r\u00e9chauffement de la plan\u00e8te entra\u00eene la fonte des glaces et fait monter le niveau des oc\u00e9ans, ce qui augmente les menaces d\u2019inondations.<\/p>\n<p>Sur une longue p\u00e9riode, les donn\u00e9es des satellites tels que ERS et Envisat de l\u2019ESA peuvent nous dire ce qui se passe.<\/p>\n<figure class=\"wp-block-image size-natural\" data-width=\"341\" data-credit=\"AP Photo\/Rachel D&#x27;Oro\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2004\/12\/antactica_012\" 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\/2004\/12\/antactica_012\/17876220-2-eng-GB\/antactica_01.jpg\" alt=\"\"><\/figure>\n<p>Les images prises depuis l\u2019espace montrent la rupture des calottes glaciaires ainsi que le d\u00e9placement des icebergs.
