Green infrastructure limits flood risk, say insurers

A new Insurance Bureau of Canada (IBC; Toronto, Ontario) report urges communities to consider green infrastructure to limit flood risk. IBC is the national industry association representing Canada’s private home, auto, and business insurers. Its member companies make up 90% of the property and casualty insurance market in Canada. The report, Combatting Canada’s Rising Flood […]

Storms as destructive as Hurricane Harvey projected to happen more frequently

When Hurricane Harvey inundated eastern Texas late last August, the eye of the storm loitered over land for nearly a week rather than dispersing as it moved farther from the ocean, as most hurricanes do. The result was a stronger, more destructive storm, which dropped a record-breaking 127 cm (50 in.) of rain and directly […]

Figure 1 from the 2018 publication (originally Figure 2.1 in the 2013 report) presents trends in different types of natural catastrophes worldwide from 1980 to 2016. The updated data shows a continuation of the trends previously observed whereby climate-related extreme events are rising, with a particularly sharp increase in hydrological events. (Data from MunichRE Natcatservice/EASAC)

New data updates earlier findings on extreme weather events

The European Academies’ Science Advisory Council (EASAC; Halle, Germany) recently released a publication that updates a previous 2013 EASAC report with new data showing that extreme weather events have become more frequent during the past 36 years. The new findings — which confirm the conclusions in the original report and extend the previous analysis — […]

Boston releases 50-year floodproofing plan to meet climate risks

Boston was built on climate resiliency planning. Early residents gradually filled in low-lying Atlantic Ocean tidelands as the city expanded. They turned small islands and peninsulas into neighborhoods high enough above sea level to prevent flooding from typical tides and storms. Today, some of these areas, such as East Boston and Charlestown, are among the […]

Habitual flooding affects many parts of low-lying South Carolina during heavy rainstorms. With mounting pressure for municipalities to address their stormwater readiness, diverse South Carolinian communities are implementing equally diverse tactics and fundraising schemes to limit runoff pollution.

South Carolina municipalities find success with site-specific stormwater management plans

In South Carolina, which barely escaped the brunt of Hurricane Irma last summer, municipal stormwater managers are demonstrating that there is no “one-size-fits-all” solution to limit runoff pollution. And as the risks of poorly conceived stormwater management plans heighten with more frequent and more intense precipitation, the state’s big cities and beach towns are taking […]

U.S. EPA Tools and Resources Webinar: National Stormwater Calculator

On Aug. 23, 2017 from 3 to 4 p.m. EDT, the U.S. Environmental Protection Agency (EPA) will discuss the National Stormwater Calculator (SWC) in a webinar. EPA developed the SWC to work toward local, state, and national stormwater management objectives. It also will support regulatory efforts to reduce runoff through infiltration and retention using green […]

Governments and landowners rush to prevent flooding from melting Sierra Nevada snowpack

A record-breaking accumulation of snow on the Sierra Nevada mountains is melting steadily as temperatures continue to warm and the thaw continues. That’s both good and bad news for Nevadans — while snowmelt represents one of the most reliable sources of drinking water for the dry West, this year it could bring up to 2.5 […]

Most U.S. coastlines will sink faster than the global average, NOAA report cautions

While sea levels across the world have long been expected to rise steadily as temperatures increase and ice caps melt, an alarming report from the National Oceanic and Atmospheric Administration (NOAA) warns that almost all U.S. coastlines risk more dramatic changes in sea level than the global average. The Jan. 19 report frames potential changes […]

UK parliament committee calls for new approaches to flood management

Faced with predictions from the U.K. government’s recent National Flood Resilience Review to expect 20% to 30% more intense rainfall due to climate change in coming years, the bipartisan Environment, Food, and Rural Affairs Committee of Parliament last month released a report calling for a complete overhaul of how the country approaches its vulnerability to […]

NCAR study portends extremely rainy 21st century

If trends toward warmer climates continue at the same pace that they have during the last few decades, the U.S. could see extreme rainfall events up to four times more frequently by the end of the 21st century, a new study by the National Center for Atmospheric Research (NCAR; Boulder, Colo.) finds. These storms could […]
