 The UN chief saw first hand scientific evidence of global warming |
Mr Ban, who has vowed to make the fight against global warming a key issue during his tenure at the UN, went to Antarctica on Friday where he heard from scientists how rising temperatures have caused huge ice shelves to collapse into the sea.
He was the first head of the UN ever to visit the frozen continent.
On Saturday the secretary general visited the majestic mountains of the Torres del Paine national park, one of Chile's top tourist attractions.
He flew over the Grey glacier, the facade of which is covered in cracks, which experts blame on changes in the weather.
