Mental health impacts of climate change and extreme weather events on mothers.

Background: The perinatal period is a time of increased vulnerability for perinatal mood and anxiety disorders (PMADs). Emotional trauma is a risk factor for PMAD development and is common among survivors of extreme weather events (EWEs), which are becoming more frequent and intense as the climate crisis progresses. EWE-related stress and anxiety have not been extensively studied in the perinatal population. However, the limited available data suggest a negative impact of EWE exposure on perinatal mental health, warranting further investigation and investment.Objective: To address this knowledge gap, we interviewed new Australian mothers to understand how EWEs affect the mental health of the perinatal population.Method: Australian mothers (18 years of age or older) with a baby under 12 months of age were recruited to participate in a single virtual focus group session (seven group sessions were run in total) and complete an anonymous survey. Participants were asked questions regarding their concerns about extreme weather and its impact, as well as their general maternal functioning. Maternal functioning, depression, and climate distress were measured via the survey.Results: The study sample comprised 31 Australian mothers (Mage = 31.74, SD = 4.86), predominantly located in Queensland. Findings from the focus groups suggested six key themes; however, of focus to this study are three themes related to maternal mental health: health and well-being, helplessness and avoidant coping, and resilience and adaptation. Predominant subthemes focused on trauma resulting from EWE exposure, economic and heat concerns, social isolation, hopelessness about the future, and feelings of resilience.Conclusions: The evidence linking adverse perinatal mental health outcomes with climate change and EWEs highlights the urgent need for interventions in this context to protect perinatal mental health and well-being. By acknowledging the traumatic impact of these experiences on mothers, this study supports advocacy for policies that specifically address this issue.

The extra consideration of navigating climatic events with children represented a complicating factor in addition to the demands of motherhood.Heat presented as a serious concern for participants, often as part of maintaining the balance between protecting their children's health and well-being and preserving their own mental health.Mothers simultaneously were disengaged from climate-related discussion or action and expressed feelings of helplessness in the face of the magnitude of climate change.

The effect of summer drought on the predictability of local extinctions in a butterfly metapopulation.

The ecological impacts of extreme climatic events on population dynamics and community composition are profound and predominantly negative. Using extensive data of an ecological model system, we tested whether predictions from ecological models remain robust when environmental conditions are outside the bounds of observation. We observed a 10-fold demographic decline of the Glanville fritillary butterfly (Melitaea cinxia) metapopulation on the Åland islands, Finland in the summer of 2018 and used climatic and satellite data to demonstrate that this year was an anomaly with low climatic water balance values and low vegetation productivity indices across Åland. Population growth rates were strongly associated with spatiotemporal variation in climatic water balance. Covariates shown previously to affect the extinction probability of local populations in this metapopulation were less informative when populations were exposed to severe drought during the summer months. Our results highlight the unpredictable responses of natural populations to extreme climatic events.

El Efecto de la Sequía Estival sobre la Previsibilidad de las Extinciones Locales en una Metapoblación de Mariposas Resumen Los impactos ecológicos de los eventos climáticos extremos sobre las dinámicas metapoblacionales y la composición de la comunidad son profundos y predominantemente negativos. Con los extensos datos de un sistema de modelos ecológicos probamos si las predicciones de los modelos ecológicos todavía son sólidos cuando las condiciones ambientales se encuentran fuera de los límites de observación. Observamos una declinación demográfica ocurrir diez veces en la metapoblación de la mariposa Melitaea cinxia en las Islas Aland de Finlandia durante el verano de 2018. Usamos datos climáticos y satelitales para demostrar que ese año fue una anomalía al contar con valores bajos de balance hídrico e índices bajos de productividad de la vegetación en todas las islas. Las tasas de crecimiento poblacional estuvieron fuertemente asociadas con la variación espaciotemporal del balance hídrico climático. Las covarianzas que previamente han afectado a la probabilidad de extinción de las poblaciones locales de esta metapoblación fueron menos informativas cuando las poblaciones estuvieron expuestas a sequías severas durante los meses de verano. Nuestros resultados resaltan las respuestas impredecibles de las poblaciones naturales ante los eventos climáticos extremos.

Surtos de diarreia na região Nordeste do Brasil em 2013, segundo a mídia e sistemas de informação de saúde – Vigilância de situações climáticas de risco e emergências em saúde / Diarrhea outbreaks in northeastern Brazil in 2013, according to media and health information systems – Surveillance of climate risk and health emergencies

Resumo Este trabalho tem como objetivo analisar as informações sobre surtos de diarreia no Nordeste do Brasil ocorridos no ano de 2013, veiculadas pela mídia eletrônica e pelos dados obtidos por sistemas de informação de saúde. Foram identificadas 33 notícias com cunho informativo sobre os surtos, algumas contendo menções sobre as causas e os fatores agravantes dos surtos de diarreia. A análise da distribuição espacial e temporal de notícias, internações e óbitos revelou que mais de 100 mil pessoas foram acometidas e, de acordo com as notícias analisadas, os estados mais atingidos foram Alagoas e Pernambuco, com maior extensão nos meses de maio a julho. O uso de fontes alternativas de água, como cacimbas, poços, caminhões-pipa e reservatórios domésticos foram apontados como as causas mais imediatas destes surtos. No entanto, outros fatores subjacentes como a precariedade estrutural dos sistemas de abastecimento de água na região do semiárido, as condições excepcionais de seca, considerada a pior dos últimos 60 anos, bem como a capacidade do setor saúde para atender um grande volume de casos, devem ser considerados para recuperar o contexto em que estes surtos são produzidos.

Abstract This study has the objective of analyzing information about diarrhea outbreaks in Brazil’s northeast in the year 2013. Information came from electronic media and from health information systems. A total of 33 news events related to diarrhea outbreaks were identified, some of them mentioning causes and aggravating factors. The analysis of spatial and temporal distribution of the news, admissions and deaths showed that more than 100,000 persons were affected and, according to the news analyzed, the most affected states were Alagoas and Pernambuco, with a greater extent in the months from May to July. The use of alternative sources of water such as ponds, wells, water trucks and household water reservoirs were identified as the most immediate causes of these outbreaks. However, other underlying factors such as precarious water supply systems in the semi-arid region, the exceptional conditions of drought, considered the worst in the last 60 years, as well as the capacity of the health sector to respond to a large number of cases, should be considered to recover the context in which these outbreaks are produced.

Cambio climático y variabilidad climática para el periodo 1981-2010 en las cuencas de los ríos Zulia y pamplonita, norte de Santander - Colombia / Climate change nnd climate variability for the period 1981-2010 in the basins of the zulia and pamplonita rivers, norte de santander - Colombia

El presente trabajo parte de una breve fundamentación teórica que soporta una estructura metodológica tendiente al cálculo de cambio climático, el estudio de la variabilidad climática en el territorio de las cuencas de los ríos Zulia y Pamplonita en Norte de Santander y la identificación inicial de medidas potenciales de adaptación al cambio climático y la variabilidad climática. En su desarrollo se identificaron y espacializaron las tendencias de cambio climático y las alteraciones más probables de los fenómenos de variabilidad climática asociados al ciclo ENSO6 para el período 1981-2010 en las cuencas objeto de estudio. Los resultados obtenidos muestran que la temperatura media ha cambiado entre 0,1 y 0,4ºC por década en las cuencas, la precipitación ha aumentado de 0 a 250 mm/década y los ciclos ENSO generan alteraciones en la variabilidad climática de las cuencas de manera diferenciada a nivel estacional e interanual, especialmente en los trimestres Dic-Ene-Feb, Jun-Jul-Ago y Sep-Oct-Nov.

This work is based on a brief theoretical foundation that supports a methodological structure aimed at the calculations of climate change, the study of climate variability in the territory of the basins of the Zulia and Pamplonita rivers in Norte de Santander and the initial identification of potential measures of adaptation to climate change and climate variability..In its development, the climate change trends and the most likely alterations of the climate variability phenomena associated with the ENSO cycle for the period 1981-2010 in the basins of the object of study were identified and spatialized. The results obtained show that the average temperature has changed between 0.1 and 0.4°C per decade in the basins, precipitation has increased from 0 to 250 mm/decade and the ENSO cycles generate alterations in the climate variability of the basins on a differentiated manner on a seasonal and year-on-year level, especially in the Dec-Jan-Feb, Jun-Jul-Aug and Sep-Oct-Nov quarters.
