Coastal cities could flood three times a week by 2045

By John Updike, 9 Feb 2017, Originally published on Climate Central The lawns of homes purchased this year in vast swaths of coastal America could regularly be underwater before the mortgage has even been paid off, with new research showing high tide flooding could become nearly incessant in places within 30 years. Such floods could occur several times a week …

Flood frequency diminishing in the southern half of most of the US, except Florida and the Gulf, while increasing across the northern US and central Midwest

A new study finds the threat of flooding is increasing in the northern half of the United States and declining in the South. The findings are based on water-height measurements at 2,042 stream and rivers, compared to NASA data showing the amount of water stored in the ground. A University of Iowa study has found that the risk of flooding …

Green infrastructure reduces flooding, increases quality of life, property values, and safety along with climate resilience

Excerpt from article at The Christian Science Monitor 20 Dec 2016 Cost-effective climate response What cities are learning is that green infrastructure could prove a low-cost approach to relieving inundated pipelines as climate change intensifies storms, all the while adding community amenities like greenspace. Heavy rainfalls are a fingerprint of climate change because a warmer atmosphere causes more evaporation and holds more …

Tidal flooding becoming more frequent with sea level rise, with flooding more than half the days of the year in sight in the next 15-30 years

“It’s a new way of thinking about risk.” said Doug Plasencia, president of the Association of State Flood Plain Managers Foundation. “We always have estimated flood risk by believing that magnitude and frequency would repeat, meaning that climate and other conditions, such as land use, were relatively stable. But now, with the changes in the climate, that is no longer …

Sea level rise could be limited to 5-6 ft this century if we keep temp increases below 2°C – transition needed in next decade or two to save east coast cities

From Joe Romm/Climate Progress, 31 Mar 2016 — We still could limit sea level rise to two feet this century if we keep total warming below 2°C, according to new analysis. Otherwise, we should be anticipating five to six feet of sea level rise by 2100 — which would generate hundreds of millions of refugees. That isn’t even the worst-case scenario.  This latest …
