A view shows the Biarritz beach, sand dune, and the promenade near the Casino during a winter storm on the Atlantic coast, southwestern France, February 22, 2015. France's Atlantic Ocean coastline, with its picturesque beaches, sandy between the Gironde estuary and the Adour River, and rocky in the Basque Country, diminishes several meters every year. Erosion from recent winter storms, with huge waves and unusual high tides, have threatened buildings and private homes on the coast, with a reduction of the beachfront by 10 meters in certain areas, the Aquitaine Coast Observatory said. Paris will host the World Climate Summit, called the COP21, from November 30 to December 11, 2015. Picture taken February 22, 2015. REUTERS/Regis Duvignau
