New Study Addresses Growing Threat of Extreme Heat in Cities Worldwide

October 4, 2021

Global map shows annual municipality-level increases in the rate of urban population exposure to extreme heat for the years from 1983 through 2016.

Rising air temperatures associated with climate change are a threat to cities throughout the world, but especially to the urban poor. The poor generally have fewer adaptive resources and less protective shelter; they have greater health vulnerability to extreme heat, and lower ability to evacuate. These conditions can be exacerbated by the urban heat island effect, where closely spaced structures with lots of pavement and limited green space, common to poorer neighborhoods worldwide, retain heat more readily and for a longer duration. Better understanding of patterns of local exposure to extreme heat is critically needed to design adaptive measures and improve health outcomes. However, until now, global, fine-resolution data on the intersection of extreme heat and population distribution in urban settings have been limited.

A new study published in the prestigious journal, Proceedings of the National Academy of Sciences (PNAS), “Global Urban Population Exposure to Extreme Heat,” is the first to combine temperature, relative humidity, and population data to provide a more detailed and comprehensive view of how extreme heat exposure is likely to impact many more people in cities around the world in the coming decades. Lead author is Earth Institute Fellow Cascade Tuholske, based at CIESIN, with co-authors Kelly Caylor, Chris Funk, Andrew Verdin, Stuart Sweeney, Kathryn Grace, Pete Peterson, and Tom Evans. The team used new, fine-resolution temperature, relative humidity, and population data to assess urban extreme heat exposure in more than thirteen thousand cities, from 1983 to 2016. Using a daily maximum wet bulb globe temperature threshold of 30°C (86°F)—which accounts for a combined impact of both temperature and humidity on human health and wellbeing—global exposure was seen to increase nearly 200% from 1983 to 2016. Total urban warming elevated the annual increase in exposure by approximately 50% compared to urban population growth alone. Exposure increased for nearly half of urban settlements worldwide, which in 2016 comprised 1.7 billion people.

The authors also found that how total urban warming and population growth drove the trajectory of exposures was not evenly distributed, thus reinforcing the importance of crafting adaptation measures that address local needs. Their findings further suggest that previous research has underestimated extreme heat exposure, underscoring the necessity for improved data to support the development of targeted adaptions such as early warning systems to reduce harmful effects, especially on the urban poor.

Data Set Enables Finer View of U.S. Social Vulnerability to Disasters

August 31, 2021

Overview map of the United States showing Social Vulnerability Index  for  2000, 2010, 2014, 2016, 2018

This summer has seen a spate of extreme climate-related events, from record high temperatures to forest fires, floods, and severe storms. Climate and other natural and manmade hazards do not affect all populations equally. Some sub-populations are particularly vulnerable to their effects owing to factors such as low income, lower levels of education, poor housing, or historical inequalities. Parsing out the fine-grained layers of social conditions across the strata of society—how much money people make, who makes up their households, minority status, ability to understand English, dwelling places, and access to transport—can provide the fundamental elements needed to quantify social vulnerability to hazards in the United States. The Centers for Disease Control (CDC) Social Vulnerability Index (SVI), created by the Geospatial Research, Analysis, and Services Program (GRASP) of the Centers for Disease Control and Prevention (CDC) and the Agency for Toxic Substances and Disease Registry (ATSDR), has long been a key resource for local officials to identify communities that may need support before, during, or after hazardous events or disease outbreaks.

To increase the utility of the SVI data set, the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN gridded the input data and removed uninhabited areas. The resulting data set, the U.S. Social Vulnerability Index (SVI) Grids, enables calculation of the SVI for user-defined areas, facilitating integration with hazard and other geospatial data. The gridded SVI data set uses the same four themes as the CDC/ATSDR index—Socioeconomic, Household Composition and Disability, Minority Status and Language, and Housing Type and Transportation—to rank communities on vulnerability for the entire United States. The SVI data set is based on inputs at the census-tract level for 15 variables for the years 2000, 2010, 2014, 2016, and 2018, and aligns with the Gridded Population of the World (GPW) data set, SEDAC′s flagship data collection.

A map gallery includes an overall SVI map and four maps visualizing each of the themes. Development of the gridded data set and maps was led by Carolynne Hultquist, post-doctoral research scientist at CIESIN.

‘Continuing’ Education at CIESIN, Despite Challenges

May 4, 2021

training workshop in Kinshasa, capital of the Democratic Republic of the Congo (DRC), May 6–9, 2019. The workshop sought to strengthen the methodology for fieldwork and data validation efforts to be implemented in the eastern DRC provinces of Tanganyika and Haut-Lomami.

As face-to-face educational activities have been curtailed or even suspended due to the pandemic, CIESIN continues to be active on diverse educational fronts, in online and hybrid venues ranging from academic settings to video series to workshops and Webinars, in addition to ongoing development of online training and curriculum resources. CIESIN staff regularly teach popular courses at graduate and undergraduate level, in a variety of departments, programs, and schools across Columbia University, including Columbia and Barnard Colleges, the Ecology, Evolution, and Environmental Biology (E3B) Department, the Mailman School of Public Health, the School of International and Public Affairs (SIPA), and the School of Professional Studies (SPS).

For the past Fall-Winter term, some CIESIN staff taught classes in “hyflex” mode (designated campus classroom, with online participation by students and faculty as needed)—for example, “Environmental Sustainability Indicators,” by associate director of Science Applications, Alex de Sherbinin, and “Data Analysis & Visualization in Sustainability,” by associate director for Geospatial Applications Greg Yetman. Both classes are in the Sustainability Management Program of the SPS. Supporting Yetman was postdoctoral research scientist Carolynne Hultquist, who taught the same class in the fall. Also this past semester, in online mode, GIS developer Kytt MacManus taught “Spatial Analysis for Sustainable Development,” and senior geographic information specialist Linda Pistolesi taught “GIS for Sustainable Development,” both for Columbia College. For E3B, research scientist Susana Adamo was instructor for “Human Populations and Sustainable Development.”  

CIESIN is also part of a major new initiative of the new Columbia Climate School. Led by Alex de Sherbinin and Kamal Amakrane, a United Nations diplomat and adjunct professor at SIPA, the Climate Mobility Network is one of nine new “Earth Networks” to facilitate interdisciplinary collaboration across Columbia University in the themes of climate, sustainability and the future of the planet. During its initial three-year phase, the Climate Mobility Network plans to develop a trans-disciplinary course, teaching aids, and tools to help build curriculum and pedagogy on climate mobility. The Network will also work on policy research and modeling in support of operational agencies, building on ongoing work with the World Bank, United Nations Development Programme, the Platform for Disaster Displacement, UNHCR-The UN Refugee Agency, and the International Organization of Migration, as well as the Columbia Global Centers Committee on Forced Migration.

Online educational activities included an educational Webinar series for a non-technical audience, with modules to date on population modelling, mapping settlements, and mapping subnational boundaries, produced by the Georeferenced Infrastructure and Data for Development (GRID3) program. In a separate effort, several online training modules in English and Spanish were co-developed by Susana Adamo, with Professor Landy Sanchez of the Center for Demographic, Urban, and Environmental Studies at El Colegio de Mexico (COLMEX), released by the Population-Environment Research Network (PERN) and supported by the International Union for the Scientific Study of Population (IUSSP) through a grant from the William and Flora Hewlett Foundation. Focused on the fundamentals of spatial data integration and geared towards demographers and other population researchers, the video-based tutorials draw on pre-packaged data and open source geographic information system (GIS) and Web-based tools. This past year, CIESIN senior geographic information specialist Dara Mendeloff participated in Earth Institute Live (EI Live), an online series for K–12 students and educators. Coordinated by the Education and Outreach Office of the Lamont Doherty Earth Observatory (LDEO), live video lessons were led by experts in a broad variety of scientific disciplines across the EI. In one session, Mendeloff gave an introduction to geographic information systems (GIS); in another, she highlighted select data science tools used in climate research. She also took part in a professional development event for K–12 educators, sponsored by the EI, which focused on teaching climate change in the classroom.

New Air Quality and Gridded Scenario Data Released

April 9, 2021

CIESIN through its NASA Socioeconomic Data and Applications Center (SEDAC) has released two new data sets, one characterizing historical air quality over the period 1998–2016, and the second projecting urban land extent into the future through 2100 under different shared Socioeconomic Pathways (SSPs). The first data set, “Annual PM2.5 Concentrations for Countries and Urban Areas, 1998–2016,” provides annual mean estimates of levels of particulate matter (particles with diameters of 2.5 microns or less) in the atmosphere, derived from observations from satellite-based sensors, for countries and urban areas. The national averages are population-weighted. This data set is based on a gridded data set developed by van Donkelaar et al., also available from SEDAC.

The data set “Global One-Eighth Degree Urban Land Extent Projection and Base Year Grids by SSP Scenarios, 2000–2100” was developed by Jing Gao of the University of Delaware and Brian O’Neill, now director of the Joint Global Change Research Institute at the University of Maryland. The data set characterizes global, spatially explicit urban land scenarios consistent with the SSPs, projected from the base year 2000 to the year 2100 at ten-year intervals, with a spatial resolution of one-eighth degree (7.5 arc-minutes). Such projections are key inputs for analyses of land use, energy use, and emissions and assessments of climate change vulnerability, impacts, and adaptation.

Peter Fox,“Titan” in the Earth Science Informatics Community, Passes Away

April 2, 2021

Peter Fox, former Tetherless World Constellation Chair and director, Information Technology and Web Science Program; he was also professor of earth and environmental sciences, computer science, and cognitive science

CIESIN joins the broad earth science and informatics communities in mourning the sudden passing of Peter Fox, who was widely respected as a key scholar, thinker, and mentor across a wide range of interrelated fields. At Rensselaer Polytechnic Institute (RPI), Fox was Tetherless World Constellation Chair and director, Information Technology and Web Science Program, as well as professor of earth and environmental sciences, computer science, and cognitive science. He was a past president of the Federation of Earth Science Information Partners (ESIP), which, together with the American Geophysical Union (AGU), the Research Data Alliance (RDA), the Committee on Data (CODATA), and other organizations, characterized Fox as a “titan” in the Earth Science informatics community.

Fox interacted regularly with many CIESIN staff members in different organizations, including ESIP, AGU, RDA, CODATA, and the International Science Council (ISC) World Data System (WDS). CIESIN director Robert Chen served with him on the ISC Strategic Coordinating Committee on Information and Data from 2009 to 2011, which helped guide the modernization and reorganization of the WDS. Fox was an active and valued member of the User Working Group (UWG) of the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN, serving a four-year term from 2009 to 2013. He was a leading proponent of the value of interdisciplinary scientific data stewardship to advance science and societal benefits. Fox was especially known as a strong and supportive mentor for many different scholars and practitioners across a wide range of fields.

Fox′s colleagues and friends at CIESIN, together with former and current members of the SEDAC UWG, are deeply saddened by this untimely loss and will greatly miss his wisdom, warmth, and wit. We extend our condolences to his family, friends, and colleagues around the world.

New Data Released on Geocoded Hazards, Infant Mortality, and Shared Socioeconomic Pathways

March 22, 2021

The NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN has released several new data sets related to hazards, infant mortality, and future socioeconomic scenarios. The Geocoded Disasters (GDIS) Dataset is a geocoded extension of a selection of natural disasters from the Centre for Research on the Epidemiology of Disaster (CRED) Emergency Events Database (EM-DAT). The data set includes nearly 40,000 locations for almost 10,000 disasters worldwide for the 58-year period spanning 1960–2018. It encompasses all EM-DAT-recorded floods, storms, earthquakes, landslides, droughts, volcanic activity and extreme temperatures, some at administrative level 3 (district/commune/village) but most at 1 (typically state/province/region). GDIS facilitates geospatial analysis of past hazard events.

The Shared Socioeconomic Pathways (SSPs) Literature Database consists of biographic information, abstracts, and analysis of 1,360 articles published 2014–2019 that make substantial use of the SSPs. The database was developed by Carole Green et al. as the basis for a recent article in Nature Climate Change that analyzes use of the Climate Change Scenario Framework and associated scenario data sets in diverse application areas and in assessments of the Intergovernmental Panel on Climate Change (IPCC). The International Committee on New Integrated Climate Change Assessment Scenarios (ICONICS) is planning to extend the literature database. SEDAC User Working Group member Brian O'Neill of the Joint Climate Change Research Institute and CIESIN director Robert Chen are members of ICONICS.

Global Subnational Infant Mortality Rates (IMR), Version 2.01, provides more recent and higher-resolution infant mortality data, including estimates of births and infant deaths. The estimates are for 234 countries and territories, 143 of which include subnational units and are benchmarked to the year 2015 (versus year 2000 for the first version). IMR data are drawn from national offices, Demographic and Health Surveys (DHS), Multiple Indicator Cluster Surveys (MICS), and other sources covering 2006–2014. The birth and infant death data can be aggregated or disaggregated to calculate IMRs at different scales or resolutions. Boundary inputs are derived primarily from the Gridded Population of the World, Version 4 (GPWv4) data collection. National and subnational data are mapped at a spatial resolution of 30 arc-seconds (~1 km at the equator), facilitating integration with demographic, environmental, and other spatial data. Data set development was led by senior geographic information specialist Dara Mendeloff and research scientist Susana Adamo.

The data set, Georeferenced U.S. County-Level Population Projections, Total and by Sex, Race and Age, Based on the SSPs, 2020–2100, contains county-level population projection scenarios of total population, and by age, sex, and race in five-year intervals for all US counties 2020–2100. These data can serve as inputs for addressing questions involving sub-national demographic change in the United States in the near, middle- and long-term.

Government of Nigeria Now Managing Spatial Data and Portal Developed by CIESIN

March 5, 2021

The Government of Nigeria, under its National Space Research and Development Agency (NASRDA), has assumed the management, hosting, and maintenance of the Nigeria data and portal that was initially developed and managed by the Geo-Referenced Infrastructure and Demographic Data for Development (GRID3) program led by CIESIN. The transition is a key step towards ensuring the long term integration and sustainability of geospatial analytics in Nigeria. GRID3 supported establishment of the infrastructure, including space and computer hardware, that is hosting the portal and geodatabase going forward. Training in managing the portal and working with the data, as well as enhancement of the original geodatabase and portal infrastructure, has been provided by Novel-T, a humanitarian-focused software and information technology company. The geodatabase and portal currently incorporate more than 1,200 data sets covering 37 states and 12 sectors, relating to subnational boundaries, human settlements, and key infrastructure such as schools, health facilities, and markets. The latest GRID3 Nigeria gridded population estimates are also available at 100m2 resolution and aggregated at the level of state, local government area (LGA), and ward. A variety of Nigerian governmental organizations have been approached to contribute data to the Nigeria portal, including the Independent National Electoral Commission (INEC), National Bureau of Statistics (NBS), National Primary Health Care Development Agency (NPHCDA), National Population Commission (NPC), Office of the Surveyor General of the Federation (OSGoF), and Universal Basic Education Commission (UBEC). CIESIN senior research associate Emilie Schnarr is GRID3 country lead for Nigeria.

Dynamic Mapping Tools for Climate Adaptation Showcased in Online Seminar

March 4, 2021

Decision support mapping tools that CIESIN developed with a team from Stevens Institute of Technology were featured in a March 3 online seminar, “Data and Tools for Climate and Flood Impacts and Adaptation Planning.” Approximately 130 people attended the seminar, which was organized by the Consortium for Climate Risk in the Urban Northeast (CCRUN) as part of the seminar series, “Green Infrastructure, Climate, and Cities.” Presenters were CIESIN senior systems analyst/GIS developer Kytt MacManus, Philip Orton of Stevens Institute of Technology, and Eric Sanderson of The Wildlife Conservation Society (WCS). MacManus gave brief demonstrations of Adaptmap, an online tool for assessing risk and flood mitigation efforts for the highly-populated areas around Jamaica Bay in New York City, and The Hudson River Flood Impact Decision Support System, an interactive map application for evaluating potential flooding of shorelines of the Hudson River Valley and Westchester County under a variety of sea level rise and storm scenarios. These dynamic model-based flood mappers have great capacity for merging flood data sources, simulating changes in flooding by including possible interactions between sea level rise, tides, storm surge, and river flows. The seminar also described Visionmaker, a tool developed by WCS to encourage community participation in adaptation planning in New York City.

New Earth Network Established on Climate Mobility

January 21, 2021

In late 2020, the Earth Institute selected four new “Earth Networks” to facilitate interdisciplinary collaboration across Columbia University and develop fresh approaches to research, education and impact on themes related to climate, sustainability and the future of the planet. The Climate Mobility Network, co-led by Ama Francis, climate law fellow with the Sabin Center for Climate Change Law and Alex de Sherbinin, CIESIN's associate director for Science Applications, seeks to catalyze research insights and data in order to guide the development of program and policy responses to climate mobility. The Network will build capacity to teach, think, and develop policy about climate mobility, which encompasses both voluntary and forced migration influenced by climate variability and change and challenging issues surrounding internal displacement, refugee flows, managed retreat, and planned relocation. The Network will build on ongoing work with the World Bank, United Nations Development Programme, the Platform for Disaster Displacement, The UN Refugee Agency, and the International Organization of Migration, as well as the Columbia Global Centers Committee on Forced Migration. During its initial three-year phase, the Climate Mobility Network plans to develop a trans-disciplinary course, teaching aids and tools to help build curriculum and pedagogy on climate mobility. It will sponsor an interdisciplinary reading group, facilitate working groups on specific topics, support blog posts and opinion pieces in major media outlets, and engage with relevant national, regional and international organizations. It is anticipated that the Network will serve as an exemplar for interdisciplinary research and practice in the new Columbia Climate School being established in 2021.
