Dear Secretary Chu: We at Washington University in St. Louis are excited that you will be visiting our University to deliver the 2010 Commencement address. The graduating class you will address is, like the larger student body, deeply concerned by the challenge climate change poses to this, and future generations. We sincerely admire your leadership and commitment to addressing this threat, and it is our hope that you will inspire us in our search for solutions to the gravest problem of our time.
