Ian Plimer - This event has been cancelled.

Historic LoDo: This event has been cancelled.

Ian Plimer, Australia’s leading geologist, will discuss and sign his controversial new book Heaven and Earth: Global Warming, the Missing Science ($21.95 Taylor Trade), which makes the case that carbon dioxide is just one of many factors that drive climate—and a relatively insignificant one at that. Heaven and Earth engagingly and comprehensively synthesizes what we know about the sun, earth, ice, water, and air, and offers a powerful argument against many of the punitive, and expensive, laws that are now being passed to protect our environment.
