WASHINGTON (AP) — Wild weather is taking a toll on roads, airports, railways and transit systems across the country.
That's leaving states and cities searching for ways to brace for more catastrophes like Superstorm Sandy that are straining the nation's transportation lifelines beyond what their builders imagined.
Despite their concerns about intense rain, historic floods and record heat waves, some transportation planners find it too politically sensitive to say aloud a source of their weather worries: climate change.
Political differences are on the minds of the American Association of State Highway and Transportation Officials, whose advice on the design and maintenance of roads and bridges is closely followed by states. The association recently changed the name of its Climate Change Steering Committee to the less controversial Sustainable Transportation, Energy Infrastructure and Climate Solutions Steering Committee.
Still, there is a recognition that the association's guidance will need to be updated to reflect the new realities of global warming.
"There is a whole series of standards that are going to have to be revisited in light of the change in climate that is coming at us," said John Horsley, the association's executive director.
In the latest and most severe example, Superstorm Sandy inflicted the worst damage to the New York subway system in its 108-year history, halted Amtrak and commuter train service to the city for days, and forced cancellation of thousands of airline flights at airports in New York, New Jersey and Philadelphia.
In Washington state, "we joked we were having 100-year storms every year," said Paula Hammond, head of the state's Department of Transportation.
Last year flooding threatened to swallow up the Omaha, Neb., airport, which sits on a bend in the Missouri River. The ground beneath the airfield became saturated, causing about 100 sinkholes and "soil boils" — uplifted areas of earth where water bubbles to the surface. The airport was spared through a massive effort that included installing 70 dewatering wells and stacking sandbags around airport equipment and buildings.
Record-smashing heat from Colorado to Virginia last summer caused train tracks to bend and highway pavement to buckle. A US Airways jet was delayed at Washington's Reagan National Airport after its wheels got stuck in a soft spot in the tarmac.
Dallas had more than five weeks of consecutive 100 degree-plus high temperatures. "That puts stress on pavements that previously we didn't see," Horsley said.
States and cities are trying to come to terms with what the change means to them and how they can prepare for it. Transportation engineers build highways and bridges to last 50 or even 100 years. Now they are reconsidering how to do that, or even whether they can, with so much uncertainty.
No single weather event, even a storm like Sandy, can be ascribed with certainty to climate change, according to scientists. But the increasing severity of extreme events fits with the kind of changing climate conditions that scientists have observed.
For example, several climate scientists say sea level along New York and much of the Northeast is about a foot higher than a century ago, mostly because of man-made global warming, and that added significantly to the damage when Sandy hit.
Making transportation infrastructure more resilient will be expensive, and the bill would come at a particularly difficult time. Aging highways, bridges, trains and buses already are in need of repair or replacement and no longer can handle peak traffic demands. More than 140,000 bridges are structurally deficient or obsolete. The problem only will worsen as the U.S. population grows.
A congressional commission estimated that all levels of government together are spending $138 billion a year less than is needed to maintain the current system and to make modest improvements.
"The infrastructure of the nation is aging and it's at risk because, quite frankly, we're all not investing enough to take care of these facilities," said Hammond, the chairwoman of the climate committee. "And now we're facing extreme weather threats that cause us to need emergency response capabilities beyond what we've had in the past."
In Washington state, "we have seen more erratic weather patterns that we haven't had before, so we really can't imagine what kind of winter or summer we're going to have anymore," Hammond said.
More frequent heavy rainfalls in the western half of the state have increased the volume and velocity of water in rivers and streams, undermining the foundations of bridges. Rising sea levels are eroding coastal roads. In the drier eastern half of the state, more frequent wildfires have forced road maintenance crews to change their methods in an effort to prevent sparks that might cause a blaze.
"Each time you replace a bridge, states have to be thinking about not just what kind of traffic demand there is, but how do I make sure this is a bridge that will withstand the future given the erratic weather patterns and climate change we're seeing," Hammond said. "It's a new layer of analysis."
About half the states have taken some steps toward assessing their most critical vulnerabilities, experts said. But few have gone to the next step of making preparations. New York was an exception. Not only had transit officials made detailed assessments of the potential effects of climate change, but they'd started to put protections in place. Subway entrances and ventilation grates were raised in low-lying areas to reduce flooding, but that effort was overwhelmed by Sandy.
"They got hit with what was even worse than even their worst-case scenario," said Deron Lovaas, a transportation expert with the Natural Resources Defense Council, an environmental group. "This was an active test of ... climate preparedness, and they failed."
While more than 97 percent of the scientists who publish peer-reviewed research say that global warming is real and man-made, the issue remains highly charged. In conservative states, the term "climate change" is often associated with left-leaning politics.
Planning for weather extremes is hampered by reluctance among many officials to discuss anything labeled "climate change," Horsley said.
"In the Northeast, you can call it climate change. ... That's an acceptable term in that region of the country," he said. "Elsewhere, in the South and the (Mountain) West, it's still not an acceptable term because of ideology or whatever you want to call it."
For example, Horsley said, in North Dakota, where there has been severe flooding in recent years, state officials avoid bringing up global warming, preferring to couch their discussions on how to shore up infrastructure as flood preparation.
The Obama administration has also shied away from talking publicly about adaptation to climate change. Transportation Secretary Ray LaHood's office refused to allow any department officials to be interviewed by The Associated Press about the agency's efforts to help states adapt. The Transportation Department and other federal agencies are involved in preparing a national assessment of climate change impacts and adaptations that may be needed. Their report is expected to be finished in the next few months.
Steve Winkelman, director of transportation and adaptation programs at the Center for Clean Air Policy, said he uses terms like "hazard mitigation" and "emergency preparedness" rather than climate change when talking to state and local officials.
"This is about my basement flooding, not the polar bear — what I call inconvenient sewer overflow," Winkelman said. "It makes it real."

As humans increase atmospheric carbon dioxide concentrations, oceans absorb some of the CO2. The resulting drop in ocean pH, known as ocean acidification, has been called <a href="http://www.huffingtonpost.com/2012/07/09/ocean-acidification-reefs-climate-change_n_1658081.html" target="_hplink">climate change's "equally evil twin"</a> by National Oceanic and Atmospheric Administration chief Jane Lubchenco. Coral reefs, which are an invaluable part of marine ecosystems and tourism economies, are threatened by ocean warming and acidification. At the 2012 International Coral Reef Symposium in Cairns, Australia, 2,600 scientists signed a petition calling for international action to preserve global coral reefs, <a href="http://www.bbc.co.uk/news/world-asia-18765584" target="_hplink">reported the BBC</a>.

Wine Tasting Parties
Winegrowers in France's Champagne region and scientists have already seen changes in the past 25 years, <a href="http://www.nytimes.com/2011/11/17/business/energy-environment/winemakers-rising-to-climate-challenge.html?_r=1&pagewanted=all" target="_hplink">reported <em>The New York Times</em></a> last year. They have "noted major changes in their vineyards, including an increased sugar content in the grapes from which they make their wine, with a consequent decrease in acidity, and a harvest time that regularly comes two weeks earlier than it once did." Last year, the <em>Telegraph</em> reported that Bordeaux, one of the world's most famous wine-producing regions, may be "<a href="http://www.telegraph.co.uk/foodanddrink/wine/8354820/Global-warming-threatens-wine-production-in-France.html" target="_hplink">unsuitable for wine-growing by 2050</a>." <a href="http://e360.yale.edu/feature/what_global_warming_may_mean_for_worlds_wine_industry/2478/" target="_hplink">Yale Environment 360 explains</a> that many European wines are tied to a specific geographical area, creating a problem for regions which may soon find themselves most suited to a new kind of grape. In the U.S., <a href="http://www.climatechangeandwine.com/noticia-detalle.php?id=421" target="_hplink">researchers at Stanford University found</a> that climate change could mean "50% less land suitable for cultivating premium wine grapes in high-value areas of Northern California."

As global temperatures rise this century, sea levels are also expected to increase. South Florida may be hit particularly hard. If greenhouse gas emissions are not reduced, global sea levels <a href="http://globalwarming.markey.house.gov/impactzones/florida.html" target="_hplink">could rise over three feet</a> by 2100, with a six foot rise possible. The U.S. Select Committee on Energy Independence and Global Warming notes: <blockquote>This threatens to submerge Florida's coastal communities and economies since roughly 9 percent of the state is within 5 feet of the existing sea level. Rising sea level also threatens the beaches, wetlands, and mangrove forests that surround the state.</blockquote> University of Florida professor Jack Putz said in 2008, "People have a hard time accepting that this is happening here," <a href="http://www.tampabay.com/news/environment/globalwarming/article435224.ece" target="_hplink">reported the <em>Tampa Bay Times</em></a>.

A 2011 report from the U.K.'s Department for Environment, Food and Rural Affairs found that climate change could affect certain infrastructure, like wireless internet. <a href="http://www.guardian.co.uk/environment/2011/may/09/climate-change-wi-fi-connections" target="_hplink">The <em>Guardian</em> reports</a>, "higher temperatures can reduce the range of wireless communications, rainstorms can impact the reliability of the signal, and drier summers and wetter winters may cause greater subsidence, damaging masts and underground cables," according to secretary of state for the environment. The <em>Guardian</em> notes, "The government acknowledges that the impact of climate change on telecommunications is not well understood, but the report raises a series of potential risks."
The Great Smoky Mountains' Smoke
The Great Smoky Mountains have the most annual rainfall in the southeastern U.S., which mostly falls as a light, misty rain, <a href="http://www.huffingtonpost.com/2012/04/28/great-smoky-mountains-climate-change_n_1461482.html" target="_hplink">explains OurAmazingPlanet</a>. A study by a team from NASA's Precipitation Measurement Missions found that "light rainfall is the dominant form of precipitation in the region, accounting for 50 to 60 percent of a year's total, governing the regional water cycle." <a href="http://www.huffingtonpost.com/2012/04/28/great-smoky-mountains-climate-change_n_1461482.html" target="_hplink">OurAmazingPlanet</a> notes: <blockquote>The results suggest the area may be more susceptible to climate change than thought; as temperatures rise, more of the fine droplets from light rain will evaporate in the air and fail to reach the ground. Lower elevations will have to contend with not only higher temperatures, but less cloud cover.</blockquote>
California Beach Bums
Along the California coast, beach communities are finding that it may be impossible to stop coastal erosion as global sea levels rise. <a href="http://www.huffingtonpost.com/2012/06/02/beach-communities-moving-inward_n_1565122.html" target="_hplink">According to AP</a>, David Revell, a senior coastal scientist at <a href="http://www.pwa-ltd.com/" target="_hplink">ESA PWA</a>, acknowledged the relentless power of the sea, saying, "I like to think of it as getting out of the way gracefully." A <a href="http://www.huffingtonpost.com/2012/06/22/west-coast-sea-level-rise_n_1619568.html" target="_hplink">report released in June by the Natural Resources Defense Council</a> found that West Coast ocean levels will rise several inches in the next few decades. Sea levels along the California coast are expected to be six inches higher by 2030 and three feet higher by the end of the century. Despite the risks, another recent NRDC study found that <a href="http://www.huffingtonpost.com/2012/04/08/california-climate-change-study_n_1409312.html" target="_hplink">California is one of several states</a> with the best plans to deal with the effects of climate change.
Repeats Of The Titanic
2012 could be a record year for the extent of Arctic sea ice at its yearly summer minimum. Walt Meier, a research scientist at the U.S. National Snow and Ice Data Center, said that with recent satellite observations, "It definitely portends a low-ice year, whether it means it will go below 2007 (the record minimum in September), it is too early to tell," <a href="http://www.huffingtonpost.com/2012/06/18/arctic-sea-ice-levels_n_1605441.html" target="_hplink">reported LiveScience</a>. As sea ice declines in the Arctic, countries are anticipating a <a href="http://www.huffingtonpost.com/2012/04/16/arctic-climate-change-military-activity_n_1427565.html" target="_hplink">competition for control of shipping lanes and mineral extraction</a> in the region. In Antarctica, research from the United States' Palmer Station on the Antarctic Peninsula has found that "87 percent of the peninsula's land-bound glaciers are in retreat," <a href="http://www.huffingtonpost.com/2012/07/12/environmental-threats-antarctica_n_1669023.html" target="_hplink">reported OurAmazingPlanet</a>. Decreasing sea ice levels were also addressed in <a href="http://www.huffingtonpost.com/2012/07/18/shell-arctic-ready-hoax-greenpeace_n_1684222.html" target="_hplink">a recent spoof of Shell's plans to drill for oil in the Arctic this summer</a>.
Crazy Sugar Highs
Climate change has already impacted sugarcane production in Indonesia. In late 2011, the <a href="http://www.thejakartapost.com/news/2011/11/09/sugar-association-blames-climate-change-production-drop.html http://www.thejakartapost.com/news/2011/11/09/sugar-association-blames-climate-change-production-drop.html" target="_hplink">chairman of the Indonesian Sugarcane Farmers Association said</a>, "sugarcane production decreased by up to 30 percent in 2011 due to climate change that has occurred since 2009."
