Despite years of urgent warnings, local governments are moving too slow to prevent the worst damage from sea-level rise caused by climate change, risking repercussions as severe as housing shortages or an injured state economy, according to a report released today by the Legislative Analyst’s office. The report suggests California would need to start building 100,000 more housing units annually in coastal cities to mitigate the problems caused by sea-level rise. Funding for public schools might be affected as well, as higher sea levels hurt property values and lower tax revenue. And it’s not just beachside housing that will be impacted.
