James Hansen:
All glaciers in America's Glacier National Park are retreating inexorably to their final demise. Global warming is real, and the melting ice is a portent of potentially disastrous consequences. Yet most gloom-and-doom climate scenarios exaggerate trends of the agents that drive global warming. Study of these forcing agents shows that global warming can be slowed, and stopped, with practical actions that yield a cleaner, healthier atmosphere.
