What are the two primary reasons that contemporary climate change is causing sea level rise? Describe why it may seem like the sea is rising faster in some places as compared to others and, in fact, may even look like it is fall in certain places. Although the sea has “only” risen about 7-9 inches (18-23 cm) over the past 100 years, why does our understanding of past sea-level changes raise concerns that sea-level rise could potentially accelerate quite rapidly over the next few decades? How is sea-level rise already impacting Florida? Discuss at least two major concerns associated with accelerating sea-level rise on coastal communities.
