William Happer is an American physicist specialising in the study of atomic physics, optics, and spectroscopy.

He is a Emeritus Professor Of Physics at Princeton University and a long-term member of the JASON advisory group, where he pioneered the development of adaptive optics.

From 1991 to 1993, he served as director of the Department Of Energy’s Office Of Science as part of the George HW Bush administration. He was dismissed from the Department Of Energy in 1993 by the Clinton administration after disagreements surrounding the ozone hole.

He was then hired by the Trump administration.


William argues that the sun is the primary driver of Earth’s changing climate.

He dismisses the idea of a ‘climate emergency‘ because the climate has changed throughout history.

William views carbon dioxide as beneficial, essential for plant growth and photosynthesis; higher levels of carbon dioxide mean more life on Earth.

The whole climate crisis is not only fake news, it’s fake science. There is no climate crisis, there’s weather and climate all around the world, and in fact carbon dioxide is a major benefit to plant growth and agriculture.
