John Holdren was President Barack Obama's Science Advisor: This is a reply he wrote to John Shanahan regarding an invitation to participate in discussions about use of fossil fuels and nuclear power. John Shanahan provides comments. Holdren's attitude in this message is typical of how he has treated very accomplished scientists and engineers who disagreed with him for over fifty years. There are a lot of professionals who disagree with him in spite of his claims that nearly the whole world of "academic" scientists agree with him.
