In 2017, Hurricane Harvey moved very slowly across parts of Texas (US) dropping “more than 30 inches of rain in two days and nearly 50 inches over four days.” “Harvey’s rainfall exceeded every known flooding event in American history since 1899.” The reason for the high rainfall totals was the slow movement of the storm–and a 2018 study (Kossin) reports that “between 1949 and 2016,…

Across much of the United States, the flood risk is greater (in some cases, far greater) than what government estimates and maps currently show. As a result, millions of homes and properties and many millions of people are facing a threat they have not thought they faced and may not have known about when they purchased or rented a property–a flooding threat that will only…

Background: Do you see a trend? More episodes of excessive, even extreme rainfall leading to widespread, frequent, and long-lasting flooding. It is happening in the midwestern United States–and other regions around the world. Is this unexpected? No, predictions since at least the 1980’s based on unrestrained climate change have forecast this very scenario. And, recent research backs it up showing “a tendency towards greater and…

Cities in the United States may face greater challenges than cities elsewhere due to complacency, denial, inadequate infrastructure, and other reasons. Yet, some U.S. cities are taking strong actions–despite the current U.S. Government Executive Branch. The climate changes that may have the greatest impact are…

See moreNews: “Large, intense thunderstorms cause flooding and fatalities.” The United States is especially impacted. Storms of this nature (mesoscale convective system-organized storms) “have increased in frequency and intensity in the USA over the past 35 years.” Research using a climate model which can “realistically simulate” this type of storm tracked changes through 2100. The result? Intense summer thunderstorms “will more than triple in North America.”…
