Why does there seem to be so much disagreement about global warming? Internationally recognized climate scientist and Pacific Northwest National Laboratory Fellow, Dr. Steven Ghan, will cut through the debate to show why 95 percent of climate scientists agree that burning wood, coal, oil, and gas is responsible for most of the observed climate change over the last 50 years and that, without deliberate action to reduce such burning, it is highly likely to change the future climate in ways that will be expensive or impossible to adapt to. He will then explain why the key issue is not the science of climate change but the global policy regarding how to meet human energy needs without excessive harm to the environment and inhabitants.
