Eighteen-year-old Sophie Kivlehan says she doesn’t remember when she first heard about climate change. It was a normal topic of conversation at the dinner table, one that often included her grandfather, Jim Hansen, an astro-physicist at Columbia University and perhaps one of the worlds’ most well-known climate scientists. Hansen began sounding the alarm about rising temperatures and rising sea levels back in the early 1980′s.
“Because we concluded already that if we burn all the coal, we’ve got a different planet,” Hansen said recently, speaking to StateImpact prior to an appearance at the University of Pennsylvania. “We’ll lose all the coastal cities. It doesn’t make sense burn all the fossil fuels, we need to look at energy policies now.”
