Global Warming and Sea level rise! New York vs. Vancouver, B.C. Canada



Vancouver B.C. and Richmond B.C. and similar low flooding areas Canada!

PlaNYC is the sustainability and resiliency blueprint for New York City. Together with our collaborators – the agencies, organizations, and New Yorkers who make this plan a reality – we have made significant progress in just a few years:

    The cleanest air in 50 years
    950,000 trees and six million square feet of reflective rooftop added to our urban landscape
    Building codes upgraded to prepare for floods, wind, and extreme weather
    19% reduction in carbon emissions since 2005, well ahead of our goal to reach 30% reduction by 2030

A changing climate, a growing population, aging infrastructure, and an evolving economy with increasing inequality pose challenges to our city’s success and quality of life. Recognizing that we determine New York's future by how we shape our response to these challenges, PlaNYC includes actions to mitigate climate change while also preparing for the risks it presents, ensuring quality of life for generations of New Yorkers to come.


Climate change could bring higher temperatures, much higher sea levels, and more flooding to NYC: report
A report by the New York City Panel on Climate Change predicts that average temperatures could jump nearly 9 degrees, rainfall could increase 13% and sea levels would increase by over two feet, meaning the daily high tides in places like Queens would cause daily flooding.

 “We expect temperatures to increase, precipitation likely to go up as well, and an acceleration of sea level rise,” said Radley Horton, a Columbia University scientist and panel member. “Sea level rise alone is going to increase the flood risk.”

Sea levels will increase 11 to 21 inches by the 2050s, 18 to 39 inches by the 2080s, and 22 to 50 inches by 2100, the group warned. And in the worst case scenario, the jump will be more than 6 feet if climate change goes unchecked.

Higher sea levels will mean more floods like the inundation brought by Sandy. The flood zone is expected to double in size by 2100, covering 99 square miles of the city.


Planning for a 100-year flood can help policy-makers plan for worse scenarios than are likely to happen. And assuming high amounts of sea-level rise can help make their plans even safer. This map assumes 10 inches of sea-level rise by the 2020s, 30 inches by the 2050s, 58 inches by the 2080s, and 75 inches by the end of the century. The map is color-coded to show which regions correspond to which scenario.

...i hope they do not loose all their money under water seepage in low areas of West Richmond B.C. and similar in the near future...!

...dikes are merely a "double dutch" risky solution to flooding if a dike is breached...!

...cheers and good luck to so much foresight...!
