Sea level rise refers to the increase in the average level of the world's oceans due to factors such as melting ice caps and glaciers, as well as the thermal expansion of seawater as it warms. This phenomenon poses significant risks to coastal communities, ecosystems, and infrastructure, leading to increased flooding and erosion. As global temperatures continue to rise, the effects of sea level rise are becoming more pronounced. Cities like Miami and New Orleans are already experiencing the impacts, prompting discussions about adaptation strategies and the need for sustainable coastal management to protect vulnerable areas from future threats.
