No COVID-19 climate silver lining in the US power sector.

ABSTRACT: Recent studies conclude that the global coronavirus (COVID-19) pandemic decreased power sector CO₂ emissions globally and in the United States. In this paper, we analyze the statistical significance of CO₂ emissions reductions in the U.S. power sector from March through December 2020. We use Gaussian process (GP) regression to assess whether CO₂ emissions reductions would have occurred with reasonable probability in the absence of COVID-19 considering uncertainty due to factors unrelated to the pandemic and adjusting for weather, seasonality, and recent emissions trends. We find that monthly CO₂ emissions reductions are only statistically significant in April and May 2020 considering hypothesis tests at 5% significance levels. Separately, we consider the potential impact of COVID-19 on coal-fired power plant retirements through 2022. We find that only a small percentage of U.S. coal power plants are at risk of retirement due to a possible COVID-19-related sustained reduction in electricity demand and prices. We observe and anticipate a return to pre-COVID-19 CO₂ emissions in the U.S. power sector.

Project description:BackgroundHealth-seeking behaviors change during pandemics and may increase with regard to illnesses with symptoms similar to the pandemic. The global reaction to COVID-19 may drive interest in vaccines for other diseases.ObjectivesOur study investigated the correlation between global online interest in COVID-19 and interest in CDC-recommended routine vaccines.Design, settings, measurementsThis infodemiology study used Google Trends data to quantify worldwide interest in COVID-19 and CDC-recommended vaccines using the unit search volume index (SVI), which estimates volume of online search activity relative to highest volume of searches within a specified period. SVIs from December 30, 2019 to March 30, 2020 were collected for "coronavirus (Virus)" and compared with SVIs of search terms related to CDC-recommended adult vaccines. To account for seasonal variation, we compared SVIs from December 30, 2019 to March 30, 2020 with SVIs from the same months in 2015 to 2019. We performed country-level analyses in ten COVID-19 hotspots and ten countries with low disease burden.ResultsThere were significant positive correlations between SVIs for "coronavirus (Virus)" and search terms for pneumococcal (R = 0.89, p < 0.0001) and influenza vaccines (R = 0.93, p < 0.0001) in 2020, which were greater than SVIs for the same terms in 2015-2019 (p = 0.005, p < 0.0001, respectively). Eight in ten COVID-19 hotspots demonstrated significant positive correlations between SVIs for coronavirus and search terms for pneumococcal and influenza vaccines.LimitationsSVIs estimate relative changes in online interest and do not represent the interest of people with no Internet access.ConclusionA peak in worldwide interest in pneumococcal and influenza vaccines coincided with the COVID-19 pandemic in February and March 2020. Trends are likely not seasonal in origin and may be driven by COVID-19 hotspots. Global events may change public perception about the importance of vaccines. Our findings may herald higher demand for pneumonia and influenza vaccines in the upcoming season.

Project description:PurposeThe coronavirus disease 2019 (COVID-19) pandemic has propelled health care workers to the front lines against the pandemic. In addition to anxiety related to infection risks, trainees have the additional burden of learning and career planning while providing care in an uncertain and rapidly changing environment. We conducted a survey to evaluate the practical and psychosocial impact on radiation oncology fellows during the first month of the pandemic.Methods and materialsA 4-part survey was designed and distributed to the fellows in our program. The survey was designed to evaluate the impact of the pandemic on scope of activity and well-being ("Impact on You") and to identify key lessons learned and social factors ("About You") using Likert scales and open-ended response options. The survey included items from the Oldenburg Burnout questionnaire.ResultsA total of 17 participants (71%) responded to the survey. Although there was a significant reduction in the mean time spent on in-person clinics (13.5 h/wk [pre-COVID] vs 9.3 h/wk [3 weeks into the COVID emergency response]; P = .002), this was replaced by virtual consults and other COVID-related activities. The proportion of respondents demonstrating features of burnout in the domains of "disengagement" and "exhaustion" was 71% and 64%, respectively. However, there was also evidence of resilience, with 47% respondents "feeling energized." Top "concerns" and "negative changes" identified related to learning, infection risk and safety, patient care, coping, and concerns about their home country. Top "positive changes" highlighted include work culture, appreciation for leadership caring for the team, the insistence on evidence to guide change, and the implementation of virtual health care.ConclusionsNegative impact needs to be anticipated, acknowledged, and managed. We anticipate understanding the positives that have emerged under these extraordinary circumstances is the "silver lining" of the pandemic, giving us tools and the best leverage to plan for the future.

Project description:Background COVID-19 pandemic school shutdowns impacted child food security. Resilient school meal programs are imperative to cope and persist through shocks and stressors. Objective To explore unforeseen positive outcomes and determine best practices during the COVID-19 pandemic for child nutrition directors in Mississippi (MS), Louisiana (LA), and West Virginia (WV). Study Design, Setting, Participants A semi-structured focus group discussion guide was developed based on the resilience capacity model (RCM). Four focus group discussions with child nutrition directors (n = 16) from MS, LA, and WV were conducted to elicit directors’ perceptions of encouraging outcomes during the COVID-19 pandemic and best practices for building resilient school meal programs. Measurable Outcome/Analysis The discussion guide was tested for content validation by subject experts and face validation by testing the guide in one focus group discussion session. The primary researcher developed a codebook based on the conceptual RCM. Two researchers independently reviewed and coded transcripts to assess interrater reliability. Predominant themes were identified using an inductive and deductive content analysis approach. Results Encouraging outcomes included acknowledgment of school nutrition staff as essential workers and recognition of child nutrition programs as important for child food security. Best practices recommended by child nutrition directors include effective communication and networking among all personnel from policymakers to staff involved in food preparation and distribution, revision of standard operating procedures to include disaster/pandemic related mitigation strategies, taking initiatives to improve school meal provision process, and emergency management training for everyone involved in school meal provision process. Director recommendations included: in-class food distribution, increased food storage, preparation, and distribution equipment, and developing a best practices policy document for each state with a comprehensive plan for emergency management situations. Conclusions Future emergency school nutrition policies should encourage efficient communication, revision of existing standard operating procedures, and implement training for all school nutrition personnel.
