Problems related to climate change continue to increase day by day. One of the problems that may threaten the future is the rise in sea levels. “Global Balance Association” has prepared a frightening report. Accordingly, after 80 years, the coastline in Istanbul and Izmir may be under water. According to experts, the rise in sea level is not visible, but will increase over time. Nearly 80 years later, places such as Üsküdar, Kadıköy, Tuzla, Yenikapı in Istanbul, and Karşıyaka and Balçova in İzmir will be seriously affected.
