Will Rapid Global Warming Resume Soon?
Braddock Linsley email@example.com
Global temperatures rose quickly until about 15 years ago, and have since largely plateaued. Now, coral records from the south Pacific Ocean suggest the so-called “hiatus” may soon end. Researchers hypothesize that water in the Pacific has slowed atmospheric warming by storing excess heat generated by CO2 emissions. But when the most recent phase of the 20-some-year Pacific Decadal Oscillation comes to an end, some of this stored heat may end up back in the air. Geochemical analysis of more than 220 years of coral growth rings from the islands of Fiji, Tonga and Rarotonga adds new support to projections that the PDO will switch states within 5-10 years, triggering a new phase of rapid warming.
Monday, Dec. 15, 8 a.m.-12:20 p.m. Moscone South Posters. A11B-3017

Battling Epidemics With Remote Sensing
Andrew Kruczkiewicz firstname.lastname@example.org, Pietro Ceccato email@example.com (Intl. Research Institute for Climate and Society)
Remote sensing is playing a key role in showing how shifts in weather drive outbreaks of deadly diseases, and how to counteract them. Kruczkiewicz will discuss how remote sensing has linked outbreaks of leishmaniasis in Sudan and South Sudan to dryer than normal conditions during the transmission months of April-July. Imagery suggests that cracks in dried-up soil—the breeding habitat of leishmaniasis-carrying sandflies—proliferate during these months, leading to outbreaks later. Ceccato will discuss programs of The Earth Institute, City University of New York and NASA to develop practical remote-sensing tools aimed at helping African nations predict and prepare for outbreaks of leishmaniasis, as well as malaria, trypanosomiasis and schistosomiasis.
Mon. Dec. 15, 5:15-5:30 p.m., 3020 Moscone West. H14A-05
Fri. Dec. 19, 11:20-11:35 a.m., 3001 Moscone West. GC52A-05

Arsenic: A Mass Poisoning In Progress
Alexander van Geen firstname.lastname@example.org
It could be the largest mass poisoning in history: the 1990s discovery that newly drilled wells meant to provide clean water across southeast Asia were instead poisoning 130 million people with natural arsenic. International efforts have since gone into studying the geology and hydrology of the problem, drilling wells into safer aquifers, and getting people to use them. But as van Geen reveals, many people are still exposed, for reasons that have as much to do with politics and public education as geologic conditions. Van Geen and colleagues are leaders in studying and remediating all aspects of the problem. They are now working in the United States as well, where new health studies are showing that wells laced with arsenic are affecting people in the eastern U.S. and Canada.

Low Ground, High Risk Seismic and Flooding Threats in Bangladesh
Christopher Small email@example.com, Leonardo Seeber firstname.lastname@example.org
A five-year program has brought into focus the potential for Bangladesh, the world’s most densely populated nation, to suffer catastrophic earthquakes, tsunamis and river-course changes—possibly all at once. Seeber and Small will discuss definitive signs of previous big quakes and at least one great tsunami; hidden features under the Ganges-Brahmaputra delta that may drive these disasters; and rapidly moving urbanization that is making the risks ever greater. The evidence rests on satellite imagery, GPS measurements, seismology and sedimentology. Posters on Thursday will delve into the details of apparent past events that could now be repeated with much greater loss of life and property.
Chris Small: Tues. Dec. 16, 8:15-8:30 a.m. U21A-02 (Invited). Leonardo Seeber: Tues. Dec. 16, 9:15-9:30 a.m. U21A-05 (Invited). 2005 Moscone West. Posters: Paleoseismic Records of Earthquakes Along the Southeastern Coast of Bangladesh., T43B-4712; Evidence for Tsunami Generated by the 1762 Great Arkan Earthquake,T43B-4732. Thurs.

Warmer Climate Threatens Airplane Takeoffs
Ethan Coffel email@example.com Radley Horton firstname.lastname@example.org (Center for Climate Systems Research)
Climate plays an important, underappreciated role in how much weight aircraft can safely carry at takeoff. Hot weather can reduce lift, forcing airlines to offload cargo and passengers, eating into their bottom line. In what may be the first study to look at the changing economics of flying in a warmer climate, researchers estimate that airlines flying out of four airports—Phoenix, Denver, New York’s LaGuardia and Washington D.C.’s Reagan—will see 50 percent to 200 percent more weight-restricted days in spring and summer by 2050-2070. Worldwide, airports at higher elevations and with short runways and limited room to expand will feel the impacts most. Future airplanes may have to be designed to compensate for reduced lift in the weather of the future.

Mapping Defenses Against Urban Heat Waves
Alex de Sherbinin firstname.lastname@example.org (Center for International Earth Science Information Network)
Already vulnerable to heat waves, city dwellers face greater risks as the planet warms. In Philadelphia, where this is already evident, geographers have combined multiple data sets to pinpoint where higher temperatures, less vegetation and a concentration of poor or elderly puts people most at risk. The map is aimed at helping the city plant trees and vegetation where needed (including on rooftops), help social workers respond, and provide other defenses. In 1980-2013, the average number of heat-wave days per year here grew from 4 to 12, largely because streets and buildings trap heat, and there are fewer trees.

Using Submarines to Chart Arctic Ocean Conditions
Raymond Sambrotto email@example.com
Since the 1990s, U.S. Navy subs cruising under Arctic Ocean ice have produced seminal data not available by other means, including measurements of thinning sea ice. The program, dubbed SCICEX, was recently expanded to sample water temperature, chemistry and biology. Sambrotto presents the latest data from the remote western Arctic, gathered in spring 2014. Among other things, it establishes the levels of nutrients under the ice available for biological productivity the following summer, when melting takes place—critical to understanding how ongoing dramatic changes in ice cover may affect Arctic ecology.

Water Systems of the Future
Upmanu Lall firstname.lastname@example.org (Columbia Water Center)
Lall, director of the Columbia Water Center, examines currently overlooked opportunities to redesign water systems to meet rising demand and declining supply. He envisions a new world in which water is treated exquisitely, like a crop of expensive vegetables, for consumption. This would include sophisticated systems to harvest rainwater; new technologies to recycle wastewater; and sensors and smart grids to monitor and manage usage in communities and buildings. He will discuss the technological, financial and social barriers that need to be overcome, and ways to accomplish that. Other talks from the Water Center during the week will cover studies of flooding in rivers from the Hudson to the Danube; newly launched satellite tools to survey global surface moisture; and the operation of China’s Three Gorges Dam.
Fri. Dec. 19, 10:35-10:50 a.m., 2009 Moscone West.
