Climate scientists see a clear relation between global warming and extreme weather events such as the catastrophic Australian bushfires that have devastated New South Wales and surrounding areas for months. What will have to happen before the society takes climate change seriously? What role will engineers play in building solutions to fight climate change? Let’s find out from Professor Steven Chu of Stanford University, who was a co-recipient of the Nobel Prize for Physics in 1997 and has devoted his scientific career to the search for new solutions to our energy and climate challenges. Prof. Chu served as the Secretary of Energy from January 2009 until April 2013, where he was charged with helping implement President Obama’s ambitious agenda to invest in clean energy and address the global climate crisis.
