Climate change may be nearing a catastrophic tipping point, but it is not too late to work towards a solution. In their new book "A Bright Future: How Some Countries Have Solved Climate Change and the Rest Can Follow" Joshua Goldstein and Staffan Qvist explain how nuclear power combined with renewables can replace fossil fuels, cut greenhouse gas emissions, and head off climate-change disaster. They challenge the left to rethink the idea that nuclear power is too dangerous and challenge the right to face the reality and perils of climate change. In the first live "Leonard Lopate at Large" of the new year, Joshua and Staffan make their case on why nuclear energy could be the last thing standing between us and the earth's destruction.
