An unexpected item is blocking cities' climate change prep: obsolete rainfall recordsLauren Sommer Heavy rain from the remnants of Hurricane Ida flooded roads and expressways in New York in 2021. In a hotter climate, rainstorms are becoming more intense. Spencer Platt/Getty Images hide caption Heavy rain from the remnants of Hurricane Ida flooded roads and expressways in New York in 2021. In a hotter climate, rainstorms are becoming more intense. American cities are poised to spend billions of dollars to improve their water systems under the federal infrastructure bill , the largest water investment in the nation's history. Those new sewers and storm drains will need to withstand rainfall that's becoming more intense in a changing climate. But as cities make plans to tear up streets and pour cement, most have little to no information about how climate change will worsen future storms. Many cities are still building their infrastructure for the climate of the past, using rainfall records that haven't been updated in decades. Those federal precipitation reports , which analyze historical rainfall data to tell cities what kinds of storms to plan for, are only sporadically updated by the National Oceanic and Atmospheric Administration. Rainfall reports for some states are 50 years old, which means they don't reflect how the climate has already changed in recent decades. And states themselves have to pay for those updates. The disconnect between the kinds of upgrades a changing climate demands and the data available to communities is already imperiling lives. Heavier downpours are taking an increasing toll on cities, inundating homes and roads. Last summer, for example, 50 people drowned when the remnants of Hurricane Ida overwhelmed urban stormwater drainage systems in the Northeast. Now, as NOAA determines how to spend its own infrastructure bill funding, many cities are hoping the agency commits to doing regular, nationwide updates of its precipitation reports, known as Atlas 14, to provide a systematic snapshot of how storms have already intensified. Still, those up-to-date records won't show how the climate will continue to change in the future. So many flood planners are also pushing NOAA to fund and release local forecasts of how rainfall is expected to intensify going forward, to ensure that infrastructure projects built today won't become obsolete as temperatures warm. "It's core to probably hundreds or thousands of development decisions everyday," says Chad Berginnis, executive director of the Association of State Floodplain Managers. "If we have over a trillion dollars going out the door in infrastructure, then let's have the very best standards and data so we're designing this stuff right." Infrastructure built for the climate of the pastWhen Hurricane Harvey hit Houston in the summer of 2017, the slow-moving storm dropped as much as 60 inches of rain. The destruction left in its wake cost $125 billion with more than 100,000 homes damaged. But even before the hurricane hit, city planners had begun to realize that storms, much weaker than Harvey, were becoming a greater danger because the infrastructure wasn't designed for them.

When rainfall overwhelms stormwater systems, flooding can happen far from a river or creek. In any city, the only thing stopping rainwater from flooding roads and homes is a lowly, unglamorous piece of infrastructure: the storm drain. In heavily paved areas, rain isn't absorbed into the ground, and the runoff needs somewhere to go. Storm drains connect to miles of underground pipelines that carry runoff away. The size of storm drains and pipes limits how much water the system can handle. When they're overwhelmed, flooding can happen in neighborhoods far from any river or creek, where residents likely lack flood insurance. Cities decide on the size of a stormwater system by using a particular kind of storm known as a "design storm." In some places, the stormwater infrastructure is designed for a storm that's considered a 1-in-5-year storm, or that has a 20% chance of hitting. Other cities plan for an even more severe storm, like a 1-in-25-year storm. To figure out how much rain those storms will unleash, many communities turn to the federal government. NOAA releases precipitation records through its Atlas 14 reports , which analyze the historical rainfall in a given region and then tell local planners how much rain is produced in both common and extreme storms. But for many states, those records are outdated. Prior to Harvey, some local agencies in Texas were using NOAA records last released in 1961 . Harris County, where Houston is located, analyzed rainfall data on its own, but the records were still 2 decades old. Regional planners knew urban flooding was on the rise. Intersections and roadways were getting swamped with water in heavy rain. But to get new precipitation data that captures how storms have already changed in recent years, local or state agencies need to pay the federal government for it under NOAA's policy. The agency itself has historically not had the budget to conduct the studies. A group of local flood agencies in Texas, along with the regional office of the U.S. Army Corps of Engineers, raised $1.75 million for a statewide study in 2016. The results confirmed what they suspected: Rainstorms have already gotten more intense. The NOAA analysis found that a major storm, known as the 1-in-100-year storm, had become almost 30% wetter. Instead of 13 inches of rain, it now dropped almost 17 inches of rain in Harris County. "It may have been a case of 'be careful what you wish for,'" says Craig Maske, chief planning officer at the Harris County Flood Control District. "We did anticipate it increasing somewhat, just not quite that much." Beefing up infrastructure at a costThe new information had a ripple effect through the various entities in Houston responsible for the metro area's infrastructure. Rainfall numbers not only determine how stormwater systems are built, but also roads, highways, bridges and housing developments. "Everybody, after taking the collective gasp of seeing how the rainfall depths had increased, knew this was going to affect how they developed and where they developed," Maske says. Transportation agencies suddenly faced building their projects to withstand more water. The Houston-Galveston Area Council, which oversees transportation planning in the area, says major projects in planning stages became $150 million to $200 million more expensive, largely due to the flood safety needs. One-third of the major roads and highways there are vulnerable to flooding, according to an agency analysis, including critical thoroughfares needed by first responders in a disaster.

Santiago/Getty Images hide caption Rainfall from the remnants of Hurricane Ida flooded homes in New Jersey. Without updated rainfall records, cities risk building infrastructure that can't withstand intensifying storms. Despite the added cost, experiencing a record-breaking disaster seemed to change the conversation in the community. "The fallout from Hurricane Harvey is still ongoing here," says Craig Raborn, director of transportation of the Houston-Galveston Area Council. "So when we do public engagement processes for major infrastructure projects, major roads, we hear a lot more comment now about flooding than we used to see in the past." Extreme storms getting more extremeAs temperatures get hotter, heavy storms are producing more rainfall because warmer air can hold more water vapor. "Throughout most of the country, big storms are happening more often," says Daniel Wright, assistant professor in civil and environmental engineering at the University of Wisconsin-Madison. "There's every reason to expect that rainfall will continue to intensify in the future." The Northeast and Midwestern U.S. have seen the biggest increases, with the heaviest storms producing 55% more rain today in the Northeast compared to 1958, according to the 2018 National Climate Assessment. Outdated rainfall records don't reflect those changes. Wright and his colleagues looked at the Atlas 14 reports and found that in some places, extreme storms are happening twice as often as those reports predicted. Under its current system, NOAA only updates the Atlas 14 information when states both request and pay for the reports. As a result, many states are using data from the early 2000s . The last update for the Pacific Northwest was in 1973. Officials at NOAA say this haphazard system is far from ideal since it creates a patchwork of climate data. Analyzing data for only a few states at a time also adds to the overall cost. "It would be much more efficient to do the whole country all at once," says Mark Glaudemans, director of NOAA's Geo-Intelligence Division, which oversees Atlas 14. "So by doing it in the piecemeal fashion that we have now, it does make it more expensive." Updating precipitation data is briefly mentioned in the $2 trillion infrastructure bill passed by Congress last year. NOAA officials say they're currently developing the agency's spending plan for the funds and can't comment on whether Atlas 14 will be part of it. Flood experts are urging the agency to prioritize nationwide rainfall reports. Without that information, cities aren't able to strengthen their infrastructure to handle today's storms, as Houston is doing. "The cost to do this is almost decimal dust when it comes to the overall federal budget," says Berginnis, whose group wrote to NOAA about the matter. "We're only talking about $3 million to $5 million a year to produce these data." Two bills now pending in Congress would also commit NOAA to doing regular updates, beyond what the infrastructure bill provides for the next decade. The PRECIP Act specifies that Atlas 14 would be released every 10 years, while the FLOODS Act would set the updates for every five years. Cities lack climate change forecastsStill, even with the most up-to-date rainfall information, climate scientists warn that infrastructure is still likely to fail, since NOAA's Atlas 14 reports look at the past, not the future. Nationwide studies like the 2018 National Climate Assessment show extreme precipitation will continue to get worse around the country as temperatures get hotter. A study last fall from the Northeast Regional Climate Center found extreme rainfall in New Jersey would likely increase by 20% by 2100 , compared to 1999. Some counties could see a 50% increase. But when cities look for climate-driven rainfall information tailored to their region, they're mostly out of luck since NOAA doesn't conduct that analysis. "There's no book," says Anna Roche, project manager at the San Francisco Public Utilities Commission. "There haven't been plans that have been developed for any of this stuff. So every city in the United States is grappling with this." Water drains on a street flooded by rain from Hurricane Harvey in 2017 in Galveston, Texas.

After getting new rainfall data, some Texas cities are building infrastructure to handle more water. In the absence of relevant information from NOAA, San Francisco and a handful of other cities around the U.S. have partnered with local universities and researchers for localized climate change projections. San Francisco is working with Lawrence Berkeley National Laboratory scientists, who are running complex computer models that forecast future rainfall change. In the Pacific Northwest, both Portland and Seattle partnered with the University of Washington's Climate Impact Group. The research team created an online tool so cities in Oregon and Washington could see how extreme rain would shift. In Seattle, the 1-in-25-year storm could be more than 20% worse by the 2080s. Realizing the scale of that change, Seattle enhanced a major stormwater control project that was underway. The Ship Canal Water Quality project was planned with a 14-foot diameter tunnel, designed to capture stormwater so the system isn't overwhelmed in big storms. The climate change projections spurred the city to upsize it to 18 feet wide. "We're thinking this is a 100-year investment, so we need to be using our best information about what 100 years is going to look like and not designing things now that will be obsolete," says Leslie Webster, drainage and wastewater planning manager at Seattle Public Utilities. "We're confident that the change in sizing will provide a lot more resilience in the future. But, you know, it also increased the price tag significantly." Still, while major cities are beginning to integrate climate data into their planning, smaller cities without connections to leading universities have little information to go on. Many are urging NOAA to release climate projections, along with a new nationwide Atlas 14 update, to provide reliable information for infrastructure planning. Other federal agencies already provide localized climate projections, like the U.S. Department of Agriculture's map showing how plant growing zones could shift. "Rural and smaller communities simply don't have the resources and typically access to technology to make those estimates," Berginnis says. The added cost of preparing for climate change comes at a tough time for most cities, which already have a backlog of maintenance for their stormwater systems. In 2020, municipal utilities nationwide faced a combined funding shortfall of $8.5 billion, according to a study from the Water Environment Federation. "Municipalities are facing an unbelievable gap in trying to keep up with stormwater," says Darren Olsen of the American Society of Civil Engineers. "It's expensive to upgrade infrastructure and stormwater infrastructure, because it's out of sight, it's out of mind." Upsizing a city's entire stormwater system, with miles of underground pipes that would need to be dug up, is far too expensive for most cities. Instead, many are looking at using green infrastructure, where pavement is replaced with plants that allow rainwater to soak into the ground. The hope for many is that the infrastructure bill provides much-needed funding to make their systems climate-ready with both traditional and green projects. "I do think it's like a cultural shift that we have to make in terms of how we plan for our future," says Nishant Parulekar, civil engineer with the city of Portland. "We'll have to be very adaptable in terms of how we plan and build."
Gauging Variability: Field-Level Comparisons Of Rain Gauge Measurements Versus FieldView™ Rainfall Estimatesby Jeff Massey, Weather Science Lead, and Zach Wienhoff, Agricultural Meteorologist Intern, Climate LLC September 19, 2018 October 5, 2017October 13, 2023, november 2, 2021. While harvest has started early for much of the nation, farmers often tell us that a big challenge during this crucial time of year is deciding when their fields are dry enough and ready to work. As the focus on weather intensifies, farmers who use Climate FieldView™ often ask why our field-level estimates may differ from a rain gauge located on, or near, a field. Listen to the "Analyzing Rainfall On Each Field" podcast now Last year, we explored how our estimates are created, how to interpret them, and how we have improved them recently . As part of our work on the Climate Weather Science team, we study how rainfall can vary a lot across a single field or an entire operation. This variability is why FieldView™ rainfall reports provide an average estimate of rainfall over a field – these rainfall estimates at the field level can be more valuable for decision-making than individual rain gauge observations. Exploring rainfall variability at the field levelRainfall can vary significantly at the field level for many reasons. For example, small storms, and small-scale features in larger storms, can produce very different rainfall amounts over short distances. To better understand rainfall variability across a field, we deployed nine high-quality rain gauges on a field at our Climate Research Farm in Martinsville, Ill. – and what we discovered was very surprising! When a half inch or more of rain fell, the average difference between the highest and lowest rainfall observations was over 0.2 inches, which is much higher than we anticipated. Below are three separate 24-hour rainfall totals for the nine rain gauges at Martinsville. For event A, rainfall varied from 0.76 inches to 1.33 inches across the field! A single rain gauge measurement could have greatly overestimated or underestimated the average rainfall that fell on this field, possibly leading to a problematic field management decision. While it is unrealistic to expect you to place and check nine or more rain gauges in each of your fields, the good news is this is not necessary. FieldView rainfall estimates represent an average for a field, and our model takes variability into account so you will get a more representative read of the rainfall in your field. This is also why our FieldView estimates may be different from a single rain gauge on a field, and why that can actually be a good thing. Exploring rainfall variability at the operation levelNow we know that rainfall can vary significantly even across a single field, but how different is rainfall across neighboring fields? To answer this question, we selected all rain gauges within a 10-mile radius near Des Moines, Iowa and analyzed the observed rainfall in comparison to FieldView rainfall estimates. Below is one example of 24-hour rainfall observations at 14 gauges in this region, along with gridded FieldView estimates. Rain gauge observations varied between 0.5 and 2.25 inches over only 10.5 miles! FieldView rainfall estimates showed even more variation from 0.4 to 2.6 inches because FieldView provides additional detail in areas without rain gauges. This analysis shows that there can be extraordinary and impactful differences in rainfall from one field to another across an entire farming operation. FieldView rainfall estimates better represent these important field-to-field differences even compared to data from multiple rain gauges. The benefits of FieldView rainfall reportsFieldView rainfall estimates are available in rainfall reports that provide an average estimate of rainfall over a field. These estimates:

PORTLAND, Maine (AP) — Aquaman might not mind if the oceans rise, but moviegoers might. That’s one of the takeaways from a new study conducted by researchers who set out to determine if today’s Hollywood blockbusters are reflective of the current climate crisis . The vast majority of movies failed the “climate reality check” proposed by the authors, who surveyed 250 movies from 2013 to 2022. The test is simple — the authors looked to see if a movie presented a story in which climate change exists, and whether a character knows it does. One film that passed the test was the 2017 superhero movie “Justice League, " in which Jason Momoa’s Aquaman character says, “Hey, I don’t mind if the oceans rise” to Ben Affleck’s Bruce Wayne. But most movies fell short — fewer than 10% of the 250 films passed, and climate change was mentioned in two or more scenes of fewer than 4% of the films. That’s out of touch with a moviegoing public that wants “to see their reality reflected on screen,” said Colby College English professor Matthew Schneider-Mayerson, lead researcher on the study. “The top line is just that the vast majority of films, popular films produced over the last 10 years in the United States, are not portraying the world as it is,” Schneider-Mayerson said. “They are portraying a world that is now history or fantasy — a world in which climate change is not happening.” Researchers at Maine’s Colby College published the study in April along with Good Energy, a Los Angeles-based environmental consultancy. The results were peer reviewed, and the authors are seeking publication in scientific journals. The researchers view the test as a way for audience members, writers and filmmakers to evaluate the representation of climate change on screen. AP AUDIO: Hollywood movies rarely reflect climate change crisis. These researchers want to change thatAP correspondent Margie Szaroleta reports on a study that finds few Hollywood films put climate change in their storylines. Some results were surprising. Movies that at first glance appear to have little overlap with climate or the environment passed the test. “Marriage Story,” Noah Baumbach’s emotive 2019 drama about the collapse of a relationship, passed the test in part because Adam Driver’s character is described as “energy conscious,” Schneider-Mayerson said. The 2022 whodunnit “Glass Onion” and the 2019 folk horror movie “Midsommar” were others to pass the test. Some that were more explicitly about climate change, such as the 2021 satire “Don’t Look Up,” also passed. But “San Andreas,” a 2015 movie about a West Coast earthquake disaster, and “The Meg,” a 2018 action movie set in the ocean, did not. The authors narrowed the selection of movies by excluding films not set on Earth or set before 2006 or after 2100. They found streaming services had a higher percentage of movies that included climate change than the major studios did. The study is “valuable for marketing purposes, informational purposes, data accumulation,” said Harry Winer, director of sustainability at the Kanbar Institute of Film and Television at the New York University Tisch School of the Arts. Winer, who was not involved in the study, said it could also help serve as an incentive to connect audiences with climate stories. “The audience will be more open to hearing a dialogue about what is right and what is wrong,” Winer said. “It’s a conversation starter.” The study authors said they see the climate reality check as a kind of Bechdel-Wallace test for climate change. Alison Bechdel, a cartoonist, is credited with popularizing that test in the 1980s by incorporating her friend Liz Wallace’s test about gender representation in film into a comic strip. The test asks if a movie includes at least two female characters who have a conversation about something other than a man. Bechdel herself spoke highly of the study’s climate test, which she described as “long overdue” in a social media post during this year’s Academy Awards season. Bechdel said in an e-mail to The Associated Press that “for a movie set in the present to ignore this existential threat just doesn’t make sense anymore” in the age of climate change. “I do worry that screenwriters might do it in a kind of rote way, which could be counterproductive, just like rote ‘strong female characters’ are,” Bechdel said. “But injecting an awareness of our communal plight into the stories we ingest seems like a no-brainer.” |
