Actor Harrison Ford spoke at the World Government Summit in Dubai, launching a scathing attack on Donald Trump and other world leaders who deny science and refuse to face the "moral crisis" of climate change.

"Around the world," said Mr. Ford, "elements of leadership including in my own country to preserve their state and the status quo, deny or denigrate science.  They are on the wrong side of history."

The 76-year-old actor and climate activist practically begged voters in healthy and semi-functioning democracies to stop electing boneheads who make a career of refusing to understand science.

"All of us whether rich or poor, powerful or powerless, will suffer the effects of climate change and ecosystem destruction," he explained in his speech.  "We are facing what I believe is the greatest moral crisis of our time.  We need nature now more than ever because nature doesn’t need people, people need nature."
