How does the frequency of extreme weather events relate to rising sea levels?

As sea levels rise, extreme weather events such as storms and high tides will increasingly lead to flooding, making these occurrences more frequent and severe.

What is the projected impact on homes in relation to chronic tidal flooding by 2050?

By 2050, more than 300,000 homes are projected to be at risk of chronic tidal flooding, and by the end of the century, this number could rise to 2.4 million.

What are the implications of using projections that suggest gradual sea level rise?

Such projections may create a false sense of security, as they suggest a gradual increase when, in reality, extreme flooding events could occur with increasing frequency before the projected dates.

What financial considerations are involved in addressing rising sea levels in Monroe County?

Initial estimates indicate that the cost to raise roads and install necessary drainage systems could reach a billion dollars or more, prompting discussions about increasing sales taxes to fund these projects.
