Heat and socioeconomic deprivation compound to drive coronary heart disease in Los Angeles
Background Socioeconomic deprivation and environmental heat exposure each increase cardiovascular risk, yet evidence is limited on how these stressors co-occur and jointly shape disease burden within cities. Mapping their overlap can inform equity-oriented planning and needs-based allocation of health and social protection resources. Methods We conducted an ecological geospatial analysis of 2,513 census tracts in Los Angeles County. Adult coronar…
Satellites, Urban Heat, and Environmental Justice
Heat waves are increasing in frequency, intensity, magnitude, and duration, causing a disproportionate impact on marginalized communities exposed to urban heat islands. Newly emerging spaceborne thermal sensing instruments, such as ECOSTRESS and Hydrosat, now have the capabilities to measure urban surface temperatures accurately at the block level (<100 m) and with enough frequency to capture transient heat waves (daily to subweekly). Such data a…
Climate constrains the enhancement of CO 2 fertilization on forest gross primary productivity
Forest gross primary production (GPP) is influenced by the interplay between climate conditions and atmospheric CO 2 levels, which interact in complex ways, generating both compensating and amplifying effects. In this study, eddy covariance flux measurements from 50 forest ecosystems were integrated with simulations from 14 terrestrial biosphere models to investigate how climate conditions and atmospheric CO 2 concentrations regulate forest GPP. …
Identifying opportunities for nature-based solutions with geospatialized life cycle assessments and fine-scale socioecological data
As we increasingly understand the impact that land management intensification has on local and global climate, the call for nature-based solutions (NbS) in agroecosystems has expanded. Moreover, the pressing need to determine when and where NbS should be used raises challenges to socioecological data integration as we overcome spatiotemporal resolutions. Natural and working lands is an effort promoting NbS, particularly emissions reduction and ca…
Tipping point in North American Arctic-Boreal carbon sink persists in new generation Earth system models despite reduced uncertainty
Estimating the impacts of climate change on the global carbon cycle relies on projections from Earth system models (ESMs). While ESMs currently project large warming in the high northern latitudes, the magnitude and sign of the future carbon balance of Arctic-Boreal ecosystems are highly uncertain. The new generation of increased complexity ESMs in the Intergovernmental Panel on Climate Change Sixth Assessment Report (IPCC AR6) is intended to imp…
Anticipating drought-related food security changes
Playing ethnographically living well together
How can we live well together? The question is critical for cities, where "wicked problems" like failing infrastructure, natural and industrial disaster, and epidemic disease pose threats to diverse forms of life. Because such problems are by definition world-shattering, it is notoriously difficult for city-dwellers to agree on how to think about them, much less overcome them. This essay sketches a collaborative ethnographic approach for co-conce…
The end of the cooperative model (as we knew it)
Cooperatives produce commons, but how they do so-and what kinds of commons they produce-cannot be known in advance. Two cooperatives in Ciudad Sandino, Nicaragua illustrate how distinct cooperative assemblages actually take shape through particular patterns of commoning. First, members of a women's sewing cooperative called the Fair Trade Zone refuse open-membership. Claiming kinship as the logic of their membership, they describe the cooperative…
Evaluation of simulated soil carbon dynamics in Arctic-Boreal ecosystems
Given the magnitude of soil carbon stocks in northern ecosystems, and the vulnerability of these stocks to climate warming, land surface models must accurately represent soil carbon dynamics in these regions. We evaluate soil carbon stocks and turnover rates, and the relationship between soil carbon loss with soil temperature and moisture, from an ensemble of eleven global land surface models. We focus on the region of NASA’s Arctic-Boreal vulner…
The Arctic-Boreal vulnerability experiment model benchmarking system
NASA’s Arctic-Boreal Vulnerability Experiment (ABoVE) integrates field and airborne data into modeling and synthesis activities for understanding Arctic and Boreal ecosystem dynamics. The ABoVE Benchmarking System (ABS) is an operational software package to evaluate terrestrial biosphere models against key indicators of Arctic and Boreal ecosystem dynamics, i.e.: carbon biogeochemistry, vegetation, permafrost, hydrology, and disturbance. The ABS …
Contribution of environmental forcings to US runoff changes for the period 1950–2010
Runoff in the United States is changing, and this study finds that the measured change is dependent on the geographic region and varies seasonally. Specifically, observed annual total runoff had an insignificant increasing trend in the US between 1950 and 2010, but this insignificance was due to regional heterogeneity with both significant and insignificant increases in the eastern, northern, and southern US, and a greater significant decrease in…
Zopilotes, Alacranes, y Hormigas (Vultures, Scorpions, and Ants)
While scholars frequently frame conflicts over urban waste in terms of a politics of infrastructure, this article frames such conflicts in terms of a politics of organization. In 2008, self‐employed recyclers in and around Managua, Nicaragua blockaded local dumps in an effort to secure rights to scavenge for resellable material. Over the course of this “garbage crisis”, a material and semiotic entanglement of human labor organization with animal …
In search of dignified work
After building the first worker-owned free trade zone in the world, the women of the Fair Trade Zone in Ciudad Sandino, Nicaragua, rejected fair trade and elected to go their own way. The small cooperative's decision, as well as their claim to be seeking "dignified work" (trabajo digno), does not express the existing norms and conventions of a local moral economy. Rather, it stems from an alternative work ethic that was formed through their parti…
Missing pieces to modeling the Arctic-Boreal puzzle
NASA has launched the decade-long Arctic-Boreal Vulnerability Experiment (ABoVE). While the initial phases focus on field and airborne data collection, early integration with modeling activities is important to benefit future modeling syntheses. We compiled feedback from ecosystem modeling teams on key data needs, which encompass carbon biogeochemistry, vegetation, permafrost, hydrology, and disturbance dynamics. A suite of variables was identifi…
Global land carbon sink response to temperature and precipitation varies with Enso phase
Climate variability associated with the El Niño-Southern Oscillation (ENSO) and its consequent impacts on land carbon sink interannual variability have been used as a basis for investigating carbon cycle responses to climate variability more broadly, and to inform the sensitivity of the tropical carbon budget to climate change. Past studies have presented opposing views about whether temperature or precipitation is the primary factor driving the …

Disentangling climatic and anthropogenic controls on global terrestrial evapotranspiration trends
We examined natural and anthropogenic controls on terrestrial evapotranspiration (ET) changes from 1982 to 2010 using multiple estimates from remote sensing-based datasets and process-oriented land surface models. A significant increasing trend of ET in each hemisphere was consistently revealed by observationally-constrained data and multi-model ensembles that considered historic natural and anthropogenic drivers. The climate impacts were simulat…
Sensitivity of inferred climate model skill to evaluation decisions
Confrontation of climate models with observationally-based reference datasets is widespread and integral to model development. These comparisons yield skill metrics quantifying the mismatch between simulated and reference values and also involve analyst choices, or meta-parameters, in structuring the analysis. Here, we systematically vary five such meta-parameters (reference dataset, spatial resolution, regridding approach, land mask, and time pe…
Fair or Balanced
This article tracks the rise and fall of the Fair Trade Zone, the first worker-owned "free trade zone" in the world. A partnership between a small development NGO and a small fair trade retailer from the US initiated the project in 1999, but a power struggle that arose between these two organizations and the worker-owners of the co-op in 2007 ultimately led to the co-op's withdrawal. This case study reflects on the rhetorical role of the concepts…

Mainstreaming local perceptions of hurricane risk into policymaking
Building Consciousness
Based on ethnographic research conducted in Nicaragua in 2007 during the early phases of the building of an industrial cotton spinning cooperative called Génesis, this article recounts an implementation of the Organization Workshop (OW), a large-scale enterprise-building and employment-generation workshop based on the ideas of Brazilian scholar-activists Clodomir Santos de Morais and Paulo Freire. The story of the Génesis OW, however, is not one …
Drought Sensitivity of the Amazon Rainforest
Amazon forests are a key but poorly understood component of the global carbon cycle. If, as anticipated, they dry this century, they might accelerate climate change through carbon losses and changed surface energy balances. We used records from multiple long-term monitoring plots across Amazonia to assess forest responses to the intense 2005 drought, a possible analog of future events. Affected forest lost biomass, reversing a large long-term car…
Balancing water, religion and tourism on Redang Island, Malaysia
Redang Island (Pulau Redang) is an island off of Peninsular Malaysia that is part of a Marine Park archipelago of corals and thousands of fish and invertebrates. The relatively isolated local community is generally centered on fishing, and Islam guides daily life. Recently, the tourism industry has expanded on the island. New hotels and resorts provide jobs, but also expose the locals to western culture and touristic behavior, which may clash wit…
