The Impact of Neglecting Climate Change and Variability on ERCOT’s Forecasts of Electricity Demand in Texas

Jangho Lee, Andrew E Dessler

Published: 2021-09-16
Subjects: Earth Sciences, Environmental Sciences, Environmental Studies, Oceanography and Atmospheric Sciences and Meteorology, Risk Analysis

The Electric Reliability Council of Texas (ERCOT) manages the electric power across most of Texas. They make short-term assessments of electricity demand based on historical weather over the last decade or two, thereby ignoring the effects of climate change and the possibility of weather variability outside of the recent historical range. In this paper, we develop an empirical methodology to [...]

Ensuring taught fieldwork is a positive, generative, collective, and valuable experience for all participants requires considerations beyond course content. To guarantee safety and belonging, participants’ identities (backgrounds and protected characteristics) must be considered as a part of fieldwork planning and implementation. Furthermore, getting fieldwork right is an important step in [...]

Story-based futures serve an important role in climate change scenario development. Stories are particularly useful in exploring sea level rise possibilities, since we know many coastal areas are specifically vulnerable to accelerating rises in sea level. This discrete change in coastline is different from most other climate change impacts, and offers a clear basis for scientifically-informed, [...]

Application of Probabilistic Machine Learning to the prediction of Remotely Sensed Vegetation Health

Ahmed T. Hammad

Published: 2021-05-28
Subjects: Environmental Studies

Every prediction of the future carries some level of uncertainty; making this explicit is challenging. This paper introduces a Probabilistic Machine Learning algorithm, namely the Natural Gradient Boosting algorithm, as a modelling tool for predicting the Vegetation Health Index, a proxy for monitoring vegetation stress in response to changing weather conditions. It then elaborates on the time [...]

Projecting long-term armed conflict risk: an underappreciated field of inquiry?

Sophie Pieternel de Bruin, Jannis Hoch, Nina von Uexkull, et al.

Published: 2021-05-27
Subjects: Environmental Studies, Human Geography, Nature and Society Relations, Social and Behavioral Sciences

Little research has been done on projecting long-term conflict risks in response to climate change. Such projections are currently neither included in the development of socioeconomic scenarios or climate change impact assessments nor part of global agenda-setting policy processes. In contrast, in other fields of inquiry, long-term projections and scenario studies are established and relevant for [...]

Defining a Sustainable Development Target Space for 2030 and 2050

By adopting the Sustainable Development Goals (SDGs), countries worldwide agreed to an agenda for achieving a prosperous, socially inclusive and environmentally sustainable future for all1. This ambition, however, also exposes a critical knowledge gap since science-based insights on how to achieve the 17 SDGs simultaneously are lacking. Quantitative goal-seeking scenario studies could enable [...]

Localised economic impacts from high temperature disruption days under climate change

Tim Summers, Erik Mackie, Risa Ueno, et al.

Published: 2021-04-22
Subjects: Climate, Environmental Studies

Most studies into the effects of climate change have headline results in the form of a global change in mean temperature. More useful for businesses and governments however are measures of the economic impact, either direct or indirect. We have addressed this by examining how the frequency of exceeding a daily mean temperature threshold changes, defined as “disruption days”, as it is often this [...]

A Regional Semi-Distributed Streamflow Model Using Deep Learning

Zhongrun Xiang, Ibrahim Demir, Ricardo Mantilla, et al.

Published: 2021-03-08
Subjects: Civil and Environmental Engineering, Engineering, Environmental Studies, Hydrology

Recent studies have shown that deep learning models in hydrological applications significantly improved streamflow predictions at multiple stations compared to traditional machine learning approaches. However, most studies lack generalization; i.e. researchers are training separate models for each location. The spatial and temporal generalization ability of deep learning models in hydrology that [...]

Land-tenure regimes determine tropical deforestation rates across socio-environmental contexts

Andrea Pacheco, Carsten Meyer

Published: 2021-03-06
Subjects: Environmental Studies

Many tropical forestlands are experiencing changes in land-tenure regimes, but how these changes may affect deforestation rates remains theoretically and empirically ambiguous. Using Brazil’s uniquely comprehensive land-tenure and deforestation data and quasi-experimental methods, we analyzed causal effects of six alternative tenure regimes on deforestation across 49 spatiotemporal scales [...]

Crisis at the Salton Sea: The Vital Role of Science

The Salton Sea—a hypersaline, terminal lake in southern California—is in crisis. A combination of mismanagement and competition among federal, state and local agencies has hindered efforts to address declining lake levels and unstable water chemistry. This delay has heightened the public health threat to regional communities as retreating shorelines expose dry lakebed— a source of potentially [...]

Subjects: Environmental Studies

In response to the 2020 COVID-19 pandemic, policymakers worldwide adopted unprecedented measures to limit disease spread, with major repercussions on labour markets and economic growth. Here we provide empirical evidence of their impact on agricultural activity due to sectoral labour reallocation. Analysing daily satellite data in a non-parametric machine learning statistical framework over [...]

Climate change research and action must look beyond 2100

Anthropogenic activity is changing Earth’s climate and ecosystems in ways that are potentially dangerous and disruptive to humans. Greenhouse gas concentrations in the atmosphere continue to rise, ensuring these changes will be felt for centuries beyond 2100, the current benchmark for prediction. Estimating the effects of past, current, and potential future emissions to only 2100 is therefore [...]

Subjects: Environmental Studies, Life Sciences

Coronavirus disease (COVID-19) pandemic has led to a lockdown worldwide. This restriction on human movements and activities significantly influences society and the environment. We examined the consequences of global lockdown for human movement and nitrogen dioxide (NO2) emissions using an air pollution index and dataset and satellite image analyses. We also evaluated the immediate (during [...]

The El Nino Southern Oscillation (ENSO) is a principal component of global climate variability known to influence a host of social and economic outcomes, but its systematic effects on human health remain poorly understood. We estimate ENSO’s association with child nutrition at global scale by combining variation in ENSO intensity from 1986-2018 with children’s height and weight from 186 surveys [...]

Accurately determining crop growth progress and crop yields at field-scale can help farmers estimate their net profit, enable insurance compa-nies to ascertain payouts, and help in ensuring food security. At field scales, the troika of management, soil and weather combine to impact crop growth pro-gress, and this progress can be monitored in-season using satellite data. Here, we use satellite [...]
