Rising sea levels refer to the increase in the average height of the ocean's surface. This phenomenon is primarily caused by two factors: the melting of ice sheets and glaciers, and the thermal expansion of seawater as it warms. As global temperatures rise due to climate change, these processes accelerate, leading to higher sea levels. The consequences of rising sea levels can be significant, affecting coastal communities and ecosystems. Areas such as Florida and Bangladesh are particularly vulnerable, facing increased flooding and erosion. This can lead to displacement of people, loss of habitat, and challenges for local economies reliant on coastal resources.
