Karen Street has an MSEE from UC, Berkeley. She worked as an electrical engineer for a number of years before becoming a teacher of high school math and physics until 1994, when after losing much of her hearing, she left teaching. On her way to becoming a science writer, she researched the differences between coal and nuclear energy and became aware of the serious threats from climate change. Since then she has worked to raise awareness of these threats through teaching, speaking and writing. Her blog focuses on climate change impacts and major solutions, in particular nuclear power and behavior change, and on evaluating the sources of information we use.
