Climate change is impacting not only the oceans but also large inland lakes. As Türkiye's fifth largest natural lake in the Mediterranean region, Lake Iznik is adversely affected by seasonal drought and presents an example of how a waterbody can and will change. Once a prominent structure on a dry land covered by water in the subsequent centuries, an ancient basilica's ruins rose up again in the lake recently. The Intergovernmental Panel on Climate Change (IPCC) considers the Mediterranean Basin, including Türkiye, as one of the most-impacted regions and most sensitive to the effects of climate change.
