Half a Degree Hotter Will Cost $30 Trillion / Beyond The Headlines / A Record Hurricane Disaster in Puerto Rico / Final Generation for the Marshall Islands? / Nooks for Nesting Islands that were once paradise are turning into places of peril, threatened by rising seas and intense hurricanes. This week we discuss Puerto Rico's high mortality in the wake of Hurricane Maria; a new study estimates thousands died as a result of the island's devastated infrastructure, which delayed medical services and cut off access to clean water and electricity.
