"Global Climate Change: The Debate about Science and Implications for Energy Policy" is the topic for a public talk at 7 p.m. Wednesday at the Richland Public Library.
Why does there seem to be so much disagreement about global warming?
Climate scientist and Battelle Lab Fellow 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 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.
The event is sponsored by the Fun Fit and Over Fifty Club.
