bridges vol. 9, April 2006 / Feature Article by Vicki Arroyo and Kate Zyla Climate change is one of the most complex issues that the world will face in this century.

Temperatures have risen over the last century and are expected to continue to rise at an increasing rate. Concentrations of greenhouse gases (GHGs) in the atmosphere have already reached levels unprecedented for hundreds of thousands of years, causing changes not only in global temperature, but also in precipitation, sea-level rise, and other observable impacts throughout the world; and these changes are happening more quickly than expected. The broad consensus of established scientific experts is that most of the warming in recent decades can be attributed to human activities. In addition, without significant steps to reduce greenhouse gas emissions to the atmosphere, the rate and severity of these changes will increase.
