You know what I'm truly grateful for this Thanksgiving? Glaciers and pristine wilderness. Both are essential to the long term health of our shared planet, and both can still be found in Antarctica. I took this photo of floating ice fragments and glaciers off the coast of the Antarctic Peninsula about ten years ago. I wonder how much less there is of this ice mass now? Ice shrinkage of the Peninsula has been accelerating since 1996, as confirmed in a 2016 study from NASA. I was amazed to discover when I traveled to Antarctica that you can not only see, but also hear, the sounds of temperature warming. When large chunks of ice separate from the ice sheet, they make violent cracking and booming sounds. It sounds a little like construction demolition. You could say it's the sound of Mother Nature blowing up. Will glaciers become our century's dinosaurs? Today, for now, I give thanks they're still here.
