Energy Secretary Steven Chu, who announced Friday that he's stepping down, is leaving with a warning that the U.S. must confront climate change.
"Ultimately we have a moral responsibility to the most innocent victims of adverse climate change. Those who will suffer the most are the people who are the most innocent: the world’s poorest citizens and those yet to be born," Chu writes in a lengthy letter Friday to Energy Department (DOE) employees.
"There is an ancient Native American saying: 'We do not inherit the land from our ancestors, we borrow it from our children.' A few short decades later, we don’t want our children to ask, 'What were our parents thinking? Didn't they care about us?,'" the letter adds.
Chu plans to remain at DOE at least through the end of February, and the letter notes, "I may stay beyond that time so that I can leave the Department in the hands of the new Secretary."
