Al Gore and Leonardo DiCaprio aren’t the only ones trying to make us afraid of global warming — Mary Mattingly’s Dry Season paints a bleak picture of Earth's possible future that's almost scary enough to make us consider turning down one of our six air conditioners. The good news: The photo is staged and digitally enhanced. The bad news: According to Al and Leo, Mattingly's vision may be prophetic. Bummer! —Rachel Wolff
