Our current system of public insurance and public disaster relief places a lot of the onus of flood risk on the taxpayer. This is certainly the case when subsidized flood insurance encourages additional coastal development and helps to maintain higher coastal home values. Also, the NFIP itself does not have the ability to pool risk since it generally applies only to flood-prone areas and it has no ability to develop a reserve in years when premiums collected exceed payouts for flood losses.

The effects of rising oceans on coastal flooding may be even worse than we thought. Scientists have found that a mere 10 to 20 centimeters of sea-level rise — which is expected by 2050 — will more than double the frequency of serious flooding events in many parts of the globe... The southern portion of Southern California may experience the brunt of sea-level rise in the region...ncludes beaches from around Point Loma all the way up to Laguna Beach, including La Jolla, Del Mar and Oceanside.

New data released by Yale researchers gives the most detailed view yet of public opinion on global warming. In Florida, the effects of climate change, including sunny-day flooding, are being felt across the state. Four southeast Florida counties — Miami-Dade, Broward, and Monroe and Palm Beach — stand out because of their concerted effort to work on climate issues together and to discuss it in nonpartisan terms.

Jakarta is one of Asia’s largest cities, with an estimated population of more than 10 million. About 20 percent of its daily waste ends up in local rivers and canals ... The Jakarta city administration, with help from international donors and the national government, is dredging its 17 rivers and canals — the first time it has done so since the 1970s. The waterways were 70 percent blocked, a central contributor to the city’s chronic flooding problems.

For decades...scientists warned that the accelerating rise of the sea would eventually imperil the United States’ coastline. Now, those warnings are no longer theoretical ... The sea has crept up to the point that a high tide and a brisk wind are all it takes to send water pouring into streets and homes.Federal scientists have documented a sharp jump in this nuisance flooding — often called “sunny-day flooding” — along both the East Coast and the Gulf Coast in recent years.

Boston is one of the most vulnerable cities in the world to sea level rise ... the World Bank suggests that Boston is the 4th at risk when you look at the property values because so much of it is low-lying ... in the mid-century with a strong surge, plus sea level rise, we could see 6 to 7 feet of water in our city which would be flooding 30 percent of our city.

New analysis shows that approximately 21 million people worldwide are affected by river floods each year on average. That number could increase to 54 million in 2030 due to climate change and socio-economic development.
