The Geological Society of America is celebrating its 125th anniversary in 2013 with a yearlong series of events focusing on Celebrating Advances in Geosciences Ц Our Science, Societal Impact and Unique Thought Processes. The geosciences have evolved greatly over the last 50 years, let alone 125 years, in terms of science and relevance to society and are posed to make informed predictions for the future. During our celebratory year, we want to look back at how far we have come since 1963, but also look forward with predictions for the future: What scientific advances have we made over the last 50 years? What new disciplines do we have now? How has our impact on society changed, our importance? What critical geoscientific issues have we addressed? Where do we stand on resolving controversial questions of 50 years ago? Is the way geoscientists think unique and how have these thought processes changed? When proposing sessions or fieldtrips, please consider this theme.
