What did humans eat during the ice age?

It is likely, however, that wild greens, roots, tubers, seeds, nuts, and fruits were eaten. The specific plants would have varied from season to season and from region to region.

Will global warming lead to another ice age?

“It is safe to say that global warming will not lead to the onset of a new ice age,” two distinguished climate scientists wrote in the journal Science.
