But thereʼs a silver lining to this dark cloud: You can still make a personal difference in preserving glacial ice.

I grew up listening to this show every Saturday at 12:06pm with my Dad, usually in the car on the way home from gymnastics. Not only that, it's an award-winning nationally syndicated show.

Of course, the seg ...read more
