French households, businesses and local authorities will face soaring costs for insurance if the country fails to adapt to a changing climate, the government said Monday.

The cost of climate disasters may double in the 30 years through 2050, reaching a cumulative €143 billion ($155 billion), it said in an adaptation plan. At a briefing in Paris, Ecology Minister Agnes Pannier-Runacher said climate change is a “tangible reality” that could leave some citizens unable to get insured.
