JUDY WOODRUFF:

Now, what do you do when your job changes, but you don't agree with the change?

For one government scientist, it forced him into the role of a reluctant whistle-blower.

Our William Brangham has our conversation.

Recently, Joel Clement had been working as a senior policy official in the Department of the Interior. His work included the Arctic and the dangerous climate change posed.

But, in June, he was reassigned, along with several dozen others, to a completely different position unrelated to his previous work.

Last week, Clement went public in a The Washington Post op-ed alleging that he was reassigned because of his work on climate change. He said he was now — quote — "a whistle-blower on an administration that chooses silence over science."

Joel Clement joins me now.

Welcome to the NewsHour.

JOEL CLEMENT, Former Director, Department of Interior Office of Policy Analysis: Thank you, William. Good to be here.
