"Climate shock." New study shows that rising property insurance premiums caused by growing weather extremes are cascading into the real estate market. Homes in the ZIP codes most exposed to hurricanes and wildfires would sell for an average of $43,900 less than they would otherwise.

A member of Congress just filled out a threat report with the Capitol Police naming the President of the United States as the person making the threat.
