This is ridiculous. True climate change has happened time and time again over millions and millions of years. Should we as humans take better care of our planet? Of course. Dispose of litter where it should go. Clean up after yourselves. Who was responsible for the "Little Ice Age" or the Earth warming to the right temp for life to begin. What about when the land bridge melted and humans could cross into other lands. Don't remember jet fuel being in the history books for back then.
