The death toll from severe floods and mudslides along Turkey's Black Sea coast has climbed to at least 57, the country's emergency and disaster agency said Saturday, as authorities disputed reports that dozens more people were missing.

       Torrential rains that pounded the provinces of Bartin, Kastamonu and Sinop on Wednesday caused flooding that demolished homes, severed at least five bridges, swept away cars and rendered numerous roads unpassable.

       Turkish disaster agency AFAD said 48 people were killed in Kastamonu, eight in Sinop and one in Bartin.

       Eight people remained hospitalized, according to the agency.

       But some residents said on social media that there are hundreds more missing, a statement also made by an opposition lawmaker.

       About 2,250 people were evacuated across the region, some lifted from rooftops by helicopters, and many were being temporarily housed in student dormitories, authorities said.

       Climate scientists unequivocally say that climate change is leading to extreme weather events as the world warms because of the burning of coal, oil and natural gas.

       Such calamities are expected to happen more frequently as the planet warms.

       Experts in Turkey, however, say interference with rivers and improper construction also were contributors to the massive damage in Turkey’s floods.

       Geologists have said that construction narrowed the river bed and the surrounding alluvial flood plain of the Ezine stream in Kastamonu’s Bozkurt district, where the damage was most severe, from 400 meters (1,312 feet) to 15 meters (49 feet).

       Residential buildings were built along the waterfront.

       During severe rains, the contracted stream has limited area in which to move and can overflow.

       The floods struck on the heels of wildfires in southern Turkey that devastated forestlands in the seaside provinces of Mugla and Antalya, which are popular with tourists.

       At least eight people died and thousands of residents were forced to flee.
