Climate Change, Disbelief, and the Collision between Human and Geologic Time
Geologic time scales are long – too long for the human mind to really comprehend. Over millions, and tens of millions, and hundreds of millions of years, the Earth has changed from something unrecognizable to the planet we see on maps, plastic globes, and photos from space. The Atlantic Ocean didn’t exist eons ago and it will literally disappear in the future as the continental plates continue to move inch by inch. A visitor from outer space millions of years ago would have looked down upon land masses and land forms unrecognizable today. As John McPhee notes in his book, Assembling California, “For an extremely large percentage of the history of the world, there was no California.” Or North America, China, Australia, Hawai’i, Mt. Everest, Grand Canyon, or any of the other landforms and natural symbols we think of as immutable.
