Earth Under Fire:
How and Why Our Climate is Changing
Presented by Robert J. Allen, Ph.D.
Department of Earth and Planetary Sciences, University of California, Riverside
Since the industrial revolution, global average surface temperature has significantly increased, likely making our planet the warmest it has been in the last millennium. This has led the Intergovernmental Panel of Climate Change to conclude that warming of the climate system is undeniable, and that most of the warming is very likely due to the observed increase in anthropogenic greenhouse gases. Human caused climate change is now likely to continue for many  centuries, including not only additional warming of our planet, but also changes in temperature extremes and precipitation, decreases in snow and ice extent, and sea level rise. We are venturing into the unknown with climate, and its associated impacts are likely to be quite disruptive. 
Experience our sonic world and the sensation of being surrounded by everyday sounds. Experiment with pitch, test your own hearing, make a movie soundtrack, and step into the ever-popular Scream Chamber!  Sort high and low pitches by hitting colored bells, create sounds by conducting an Invisible Orchestra , and launch a billiard ball to show how sound hitting our eardrums sends signals to our brain.
