I have a lot of sympathy for the climate skeptics. It really is hard to believe that our disorganized little species could have embarked on a project as grand as changing our planet’s atmosphere. Sarah Palin, tapping on some sort of wireless device, recently wrote that it’s “Arrogant&Naive2say man overpwers nature… R duty2responsbly devlop resorces4humankind,” and unlike many of her bons mots, this one was almost poignant. We look skyward and still feel small. And we are, individually.
