The core of Mars used to be liquid. When it cooled the magnetic field that protected it vastly away around 4 billion years ago.

I believe they mean that the molten core induced a magnetic field which protected the atmosphere from being stripped away by the solar winds, and when the core solidifed the magnetic field went away and the solar winds... well, they went to town. The atmosphere had allowed energy to be trapped, providing heat enough for the water to remain liquid
