US EAST COAST CITIES: FLOODING CAUSED BY CLIMATE CHANGE

A new report warns that dozens of America’s east coast cities will face routine tidal flooding caused by climate change.

According to the study, Miami will undertake adequate measures deploying new pumps to hold back the waters of the King Tides, the highest annual high tides, which are projected to crest at 3.5 feet (1.07m). In addition to that, researchers have explained that other cities are going to have to establish similar strategies in order to avoid the same kind of problems in the future.

The report also has alarmingly forecast that most of the towns on America’s east coast will see triple the number of flooding events by 2030.

Furthermore, the research has shown that by 2045 tidal floods will seep further inland, and last even longer.

Many coastal cities already face dozens of small tidal floods every year, lasting only a few hours. However, the frequency of such events will increase because of sea level rise, the report says.

To highlight the urgency of this situation, the study has indicated that some east coast towns have recorded four times as many flood days as in 1970. To make an example, Washington DC, that already experiences flooding from the Potomac River during hurricanes, will have to deal with chronic flooding, with 388 occurrences a year by 2045.

Moreover, researchers indicate that the frequency of these floods will worsen over time: by 2045, half of the towns can expect to see more than 100 tidal floods a year. Also, nine of those towns would face tidal floods 240 times a year by 2045. 

In this framework, experts have stressed that without serious intervention, frequent flooding will undermine daily life, changing the way an area functions.
