From the article:
"New University of Melbourne research has revealed that ice ages over the last million years ended when the tilt angle of the Earth's axis was approaching higher values. During these times, longer and stronger summers melted the large Northern Hemisphere ice sheets, propelling the Earth's climate into a warm 'interglacial' state, like the one we've experienced over the last 11,000 years."
