The violence that killed 128 or more people, injured many more and instilled fear in Paris this past Friday is deeply painful. We mourn the losses that have been suffered. Such acts cannot be justified or rationalized. They are simply immoral and have no legitimacy.In just two weeks, thousands of delegates will convene in Paris for the 21st Conference of the Parties (COP21) to the UN Framework Convention on Climate Change. Our small delegation of Dickinson College students, recent graduates and I will be among them.
