The state has bought and torn down 145 homes since 2013 in Woodbridge, New Jersey, with eight homes demolished this month alone. Dozens more are slated to be torn down in the near future. It's all part of an effort to get ahead of climate change. Some neighborhoods in this town of over 100,000 residents just off the bustling New Jersey Turnpike are projected to be partly or fully underwater in coming decades as global sea levels rise.
