18 December 2017, Inman, The coastal mortgage time bomb. Experts worry that if insurers start to pull out of flood-prone seaside communities, it could cause a crisis worse than 2008. 2017 will be remembered as the year the water came. Hurricane Harvey dropped as much as 60 inches of rain on parts of Houston, shattering American meteorological records. Hurricane Irma was the strongest tropical storm ever recorded outside the Gulf of Mexico and the Caribbean Sea, and plowed through Florida in early September, turning Miami’s main drag into a raging river. And Category 4 Hurricane Maria pulverized Puerto Rico with 150-mph winds, leaving the island in darkness and ruin. Altogether, the three storms will cost the U.S. more than $200 billion, which would make 2017 the most expensive hurricane season on record.Yet there is every reason to expect that the towns and the cities hit by the hurricanes of 2017 will be rebuilt — even, eventually, devastated Puerto Rico. Thank the federal government — when a storm or flood strikes a community, Washington is there with generous disaster relief, either through billions of dollars in direct aid or through the cushion of federally-subsidized flood insurance plans. The confidence in the federal government’s backing keeps lenders sending money to disaster-hit communities, which encourages residents to stay put and rebuild, rather than flee for safer areas. This in turn ensures that tax money keeps flowing to local governments. That’s why New Orleans, more than 10 years after suffering through one of the worst hurricanes on record, now has a tax base twice as large as it did before Katrina, and why the South Florida city of Homestead is nearly three times as populous as it was before Hurricane Andrew flattened it in 1992.

13 December 2017, World Weather Attribution, Climate Change Fingerprints Confirmed in Hurricane Harvey’s Record-Shattering Rainfall. Scientist with World Weather Attribution (WWA) find that human-caused climate change made the record rainfall that fell over Houston during Hurricane Harvey roughly three times more likely and 15 percent more intense. WWA is releasing the findings of its new analysis regarding the role of human-induced climate change on Hurricane Harvey’s devastating rains that is published in the peer-reviewed journal, Environmental Research Letters (ERL). The findings are being released jointly with the American Geophysical Union (AGU) in a joint press release and at a press conference on Wednesday, December 13 at 2:30 p.m. CT at the annual AGU Fall Meeting in New Orleans. The paper can be found on our website and in Environmental Research Letters.
13 December 2017, American Meteorological Society, Explaining Extreme Events from a Climate Perspective. This Bulletin of the American Meteorological Society (BAMS) special report presents assessments of how human-caused climate change may have affected the strength and likelihood of individual extreme events. This sixth edition of explaining extreme events of the previous year (2016) from a climate perspective is the first of these reports to find that some extreme events were not possible in a preindustrial climate. The events were the 2016 record global heat, the heat across Asia, as well as a marine heat wave off the coast of Alaska. While these results are novel, they were not unexpected. Climate attribution scientists have been predicting that eventually the influence of human-caused climate change would become sufficiently strong as to push events beyond the bounds of natural variability alone. It was also predicted that we would first observe this phenomenon for heat events where the climate change influence is most pronounced. Additional retrospective analysis will reveal if, in fact, these are the first events of their kind or were simply some of the first to be discovered. Read More here
