CapsuleFloridians’ risk perceptions regarding sheltering and COVID-19 were evaluated during the 2020 hurricane season. Results show that many view shelters as high-risk and would choose sheltering-in-place instead of risking exposure.

This study examines risk perceptions and evacuation planning for those residents affected by Hurricane Laura–the first major hurricane evacuation during the COVID-19 pandemic–and Hurricane Sally, prior to the widespread availability of vaccines. Research on hurricane evacuation behavior and risk perceptions during a pandemic is critical for quantifying the intersect of these compounding threats. Analyses captured how people perceive public shelters and whether evacuation choices changed in light of the pandemic. Many study participants considered themselves vulnerable to COVID-19 (39.4%) and two-thirds believed it would be “very serious” if they or their loved ones contracted COVID-19, but this had no impact on their actual evacuation decision-making. Approximately 75% of the sample stayed at home during Hurricanes Laura or Sally, and of these, just over 80% indicated that COVID-19 was a somewhat important deciding factor. This reflects the partial role that COVID-19 played in balancing individual and household protective action decision-making during complex disasters. Whereas 15.5% wanted to evacuate but waited until it was too late. For those who evacuated to a hotel, many found that staff and guests wore masks and socially distanced in common spaces. Of particular interest is that individuals have a continued negative perception of public shelters’ ability to safeguard against COVID-19 which was coupled with a significant decrease in the number of respondents that would potentially use shelters in 2020 compared to before the COVID-19 pandemic. These results have and will inform future hazard mitigation planning during the current or future pandemic, or infectious disease outbreaks.

With the continued social distancing requirements of the novel COVID-19 pandemic, many in-person educational programs were halted in 2020, including specialty education and research experiences for undergraduates. However, some Research Experiences for Undergraduates (REUs) progressed in Summer 2020 in a fully virtual format. The importance of understanding how these practical STEM skills translated in a virtual REU format, in addition to areas of improvement going forward, are critical to the development of effective online STEM learning through REUs. Two survey instruments were designed to capture data from both the REU mentors (including the PIs) and the students in the programs. Questions included information on the REU they participated in, their perceptions of the best and worst aspects, their overall satisfaction with the experience, and their likelihood to seek out virtual REUs in the future. Overall, both students and faculty involved in virtual REUs were glad to have had the experience and were satisfied with it. The benefits of flexibility, the ease of communication and scheduling, and the increased access to online resources were echoed as the strengths of the virtual format. However, many believe that an in-person REU had benefits that could not be replicated in a virtual environment including community building and hands-on experiences. Several were bogged down by technical difficulties. With more effort made to include community building to a greater extent, as well as considerations and planning for technical demands, the future of widely accessible online REU experiences is a bright one.

The Arctic is especially vulnerable to climate change and is warming faster than the global average. Changes in this region pose a heightened threat due to the immense amount of carbon frozen as organic material in the soil. When permafrost thaws, organic material decays and releases as greenhouse gases into the atmosphere, contributing to further warming. A better understanding of the processes that influence permafrost degradation is needed to inform climate adaptation and mitigation planning. This study assesses changes to Arctic permafrost across 35 ensemble member simulations from the Community Earth System Model 1 Large Ensemble Project, under the Representative Concentration Pathway 8.5 21st century scenario. Most Arctic near‐surface permafrost is lost by 2100, but timing varies across regions and with soil depth. Internal climate variability, represented by differences between ensemble members, has a constrained influence on degradation timing due to relative consistency of summer temperature increases and insulation by winter snow cover.

Since the onset of the COVID-19 pandemic, decision-making during disasters fundamentally changed to accommodate the combined risks of hurricanes and infectious diseases. Prior research conducted in 2020 by Collins et al. (2021a, 2021b, 2022) examined how individuals changed their intended evacuation decision-making during the pandemic or their actual evacuation decisions during Hurricanes Laura and Sally. Hurricane Ida provided further data on evacuation decision-making when vaccinations and masks were widely available. A digital survey was disseminated to individuals affected by Hurricane Ida in 2021. Respondents provided information about their actual evacuation choices and perceptions of public shelters and COVID-19 risks. Compared to the 2020 hurricane season, more individuals have reduced negative perceptions of hurricane shelters. However, individuals were less likely to utilize public shelters than in the 2020 season, with 11.4% more individuals stating they would definitely or probably avoid using shelters in 2021. Fewer individuals identified that COVID-19 was a primary reason they chose to stay home during Hurricane Ida (19.5% compared to 86.8% during Hurricanes Laura and Sally). Furthermore, respondents with health risks for severe COVID-19 symptoms were no more likely to evacuate than those respondents who had no health risks. Potentially, as the pandemic progressed and vaccine availability and COVID-19 management improved, COVID-19 has had less impact on evacuation decision-making. The results from this work should guide planners in emergency management and public health in future hurricane seasons and future pandemics or other outbreaks to anticipate behavior changes and properly manage infectious disease threats.
