Iowa native James Hansen discusses climate change at TED Conference

In February, Iowa native and climate change expert, James Hansen, spoke at a TED Conference.

Hansen’s speech, entitled “Why I must speak out about climate change”, discussed both the science behind climate change and his frustrations in communicating climate change.

In 1981, Hansen published a paper predicting many of the effects of climate changes we are seeing today. During the ‘80’s Hansen testified to congress about the importance of recognizing climate change. After facing harsh criticism, Hansen backed away from public speaking for about 15 years and focused solely on research.

Beginning in 2006, Hansen renewed his public speaking efforts out of frustration for the lack of progress in addressing climate change.

Hansen was born in Denison, Iowa, and studied under James Van Allen at the University of Iowa.
