the Antarctic are regions that have a lot of ice and acts as air conditioners for the Earth system. This year, Antarctic sea ice reached a record maximum extent while the Arctic reached a minimum extent in the top ten lowest since satellite records began. One reason we are seeing differences between the Arctic and the Antarctic is due to their different geographies. As for what's causing the sea increase in the Antarctic, scientists are also studying ocean temperatures, possible changes in wind direction and, overall, how the region is responding to changes in the climate.Here is the YouTube video. || ", "release_date": "2014-10-08T10:00:00-04:00", "update_date": "2023-05-03T13:50:27.803483-04:00", "main_image": { "id": 450705, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a011700/a011703/G2014-093-Antarctic-1920-master_youtube_hq_print.jpg", "filename": "G2014-093-Antarctic-1920-master_youtube_hq_print.jpg", "media_type": "Image", "alt_text": "For complete transcript, click here.", "width": 1024, "height": 576, "pixels": 589824 } } ], "sources": [], "products": [], "newer_versions": [], "older_versions": [], "alternate_versions": [] }
