UNITED NATIONS (AP) — Economic losses from disasters since 2000 are in the range of $2.5 trillion, a figure at least 50 percent higher than previous international estimates, according to a U.N. report released Wednesday.

The U.N. Office for Disaster Risk Reduction warned in the 246-page report that economic losses from floods, earthquakes and drought will continue to escalate unless businesses take action to reduce their exposure to disaster risks.
