RESUMO
Although anthropogenic climate change is expected to have caused large shifts in temperature and rainfall, the detection of human influence on global drought has been complicated by large internal variability and the brevity of observational records. Here we address these challenges using reconstructions of the Palmer drought severity index obtained with data from tree rings that span the past millennium. We show that three distinct periods are identifiable in climate models, observations and reconstructions during the twentieth century. In recent decades (1981 to present), the signal of greenhouse gas forcing is present but not yet detectable at high confidence. Observations and reconstructions differ significantly from an expected pattern of greenhouse gas forcing around mid-century (1950-1975), coinciding with a global increase in aerosol forcing. In the first half of the century (1900-1949), however, a signal of greenhouse-gas-forced change is robustly detectable. Multiple observational datasets and reconstructions using data from tree rings confirm that human activities were probably affecting the worldwide risk of droughts as early as the beginning of the twentieth century.

Streamflow often increases after fire, but the persistence of this effect and its importance to present and future regional water resources are unclear. This paper addresses these knowledge gaps for the western United States (WUS), where annual forest fire area increased by more than 1,100% during 1984 to 2020. Among 72 forested basins across the WUS that burned between 1984 and 2019, the multibasin mean streamflow was significantly elevated by 0.19 SDs (P < 0.01) for an average of 6 water years postfire, compared to the range of results expected from climate alone. Significance is assessed by comparing prefire and postfire streamflow responses to climate and also to streamflow among 107 control basins that experienced little to no wildfire during the study period. The streamflow response scales with fire extent: among the 29 basins where >20% of forest area burned in a year, streamflow over the first 6 water years postfire increased by a multibasin average of 0.38 SDs, or 30%. Postfire streamflow increases were significant in all four seasons. Historical fire-climate relationships combined with climate model projections suggest that 2021 to 2050 will see repeated years when climate is more fire-conducive than in 2020, the year currently holding the modern record for WUS forest area burned. These findings center on relatively small, minimally managed basins, but our results suggest that burned areas will grow enough over the next 3 decades to enhance streamflow at regional scales. Wildfire is an emerging driver of runoff change that will increasingly alter climate impacts on water supplies and runoff-related risks.

OBJECTIVE: We examined the differences in health care spending and utilization, and financial hardship between Traditional Medicare (TM) and Medicare Advantage (MA) enrollees with mental health symptoms. DESIGN: Cross-sectional study. PARTICIPANTS: We identified Medicare beneficiaries with mental health symptoms using the Patient Health Questionnaire-2 and the Kessler-6 Psychological Distress Scale in the 2015-2021 Medical Expenditure Panel Survey. MEASUREMENTS: Outcomes included health care spending and utilization (both general and mental health services), and financial hardship. The primary independent variable was MA enrollment. RESULTS: MA enrollees with mental health symptoms were 2.3 percentage points (95% CI: -3.4, -1.2; relative difference: 16.1%) less likely to have specialty mental health visits than TM enrollees with mental health symptoms. There were no significant differences in total health care spending, but annual out-of-pocket spending was $292 (95% CI: 152-432; 18.2%) higher among MA enrollees with mental health symptoms than TM enrollees with mental health symptoms. Additionally, MA enrollees with mental health symptoms were 5.0 (95% CI: 2.9-7.2; 22.3%) and 2.5 percentage points (95% CI: 0.8-4.2; 20.9%) more likely to have difficulty paying medical bills over time and to experience high financial burden than TM enrollees with mental health symptoms. CONCLUSION: Our findings suggest that MA enrollees with mental health symptoms were more likely to experience limited access to mental health services and high financial hardship compared to TM enrollees with mental health symptoms. There is a need to develop policies aimed at improving access to mental health services while reducing financial burden for MA enrollees.

'Ramping' is a commonly used term in contemporary Australian healthcare. It is also a part of the public and political zeitgeist. However, its precise definition varies among sources. In the published literature, there are distinctions between related terms, such as 'entry overload' and 'Patient Off Stretcher Time Delay'. How ramping is defined and how it came to be defined have significance for policies and procedures relating to the described phenomenon. Through examination of the history of the term, insights are obtained into the underlying issues contributing to ramping and, accordingly, associated possible solutions.
RESUMO
Dr. Esther Duflo, Nobel Laureate in Economics, and co-founder and co-director of the Abdul Latif Jameel Poverty Action Lab (J-PAL) sat down with Dr. Benjamin Cook for a "fireside chat" at the 12th National Institute of Mental Health Global Mental Health Research Without Borders Conference. Dr. Duflo discussed J-PAL's efforts to develop and test interventions for improving mental health and how cash transfer programs can be used to improve mental health. She also discussed the importance of using randomized control trials (RCTs) in shaping global mental health initiatives. Dr. Duflo shared insights from projects addressing loneliness among older individuals in India, secondary school scholarships in Ghana, and other studies that have informed social policies. Looking forward, she discusses climate change as a threat to the reductions in poverty realized in the last 30 years and encourages the expansion of networks of research and policy collaborations to improve global health.

Importance: Poverty is associated with greater barriers to health care and worse health outcomes, but it remains unclear whether income support can improve health. Objective: To examine the effect of cash benefits on health care utilization and health. Design, Setting, and Participants: The City of Chelsea, Massachusetts, a low-income community near Boston, randomly assigned individuals by lottery to receive cash benefits. Participants' medical records were linked across multiple health systems. Outcomes were assessed during the intervention period from November 24, 2020, to August 31, 2021. Intervention: Cash benefits via debit card of up to $400 per month for 9 months. Main Outcomes and Measures: The primary outcome was emergency department visits. Secondary outcomes included specific types of emergency department visits, outpatient use overall and by specialty, COVID-19 vaccination, and biomarkers such as cholesterol levels. Results: Among 2880 individuals who applied for the lottery, mean age was 45.1 years and 77% were female. The 1746 participants randomized to receive the cash benefits had significantly fewer emergency department visits compared with the control group (217.1 vs 317.5 emergency department visits per 1000 persons; adjusted difference, -87.0 per 1000 persons [95% CI, -160.2 to -13.8]). This included reductions in emergency department visits related to behavioral health (-21.6 visits per 1000 persons [95% CI, -40.2 to -3.1]) and substance use (-12.8 visits per 1000 persons [95% CI, -25.0 to -0.6]) as well as those that resulted in a hospitalization (-27.3 visits per 1000 persons [95% CI, -53.6 to -1.1]). The cash benefit had no statistically significant effect on total outpatient visits (424.3 visits per 1000 persons [95% CI, -118.6 to 967.2]), visits to primary care (-90.4 visits per 1000 persons [95% CI, -308.1 to 127.2]), or outpatient behavioral health (83.5 visits per 1000 persons [95% CI, -182.9 to 349.9]). Outpatient visits to other subspecialties were higher in the cash benefit group compared with the control group (303.1 visits per 1000 persons [95% CI, 32.9 to 573.2]), particularly for individuals without a car. The cash benefit had no statistically significant effect on COVID-19 vaccination, blood pressure, body weight, glycated hemoglobin, or cholesterol level. Conclusions and Relevance: In this randomized study, individuals who received a cash benefit had significantly fewer emergency department visits, including those related to behavioral health and substance use, fewer admissions to the hospital from the emergency department, and increased use of outpatient subspecialty care. Study results suggest that policies that seek to alleviate poverty by providing income support may have important benefits for health and access to care.
RESUMO
African American caregivers providing informal kinship care are vulnerable to chronic stress. Research has indicated stress increases individuals' risk for many adverse physical and mental health outcomes, including cardiovascular disease, Alzheimer's disease and depression. Given the adverse outcomes related to stress, identifying mechanisms to help these caregivers lower and manage their stress is critical to their overall health and well-being. This pilot qualitative study aimed to explore the self-care practices of 12 African Americans providing informal kinship care using a phenomenological approach. Three themes emerged: (a) behaviours to manage stress levels, (b) support network reminding caregivers to take care of themselves and (c) prioritizing my own needs. Specifically, our findings indicate that some caregivers have high-stress levels and engage in maladaptive coping behaviours. The children they cared for reminded them to take care of themselves by attending doctors' appointments or getting their nails done. Nevertheless, some caregivers prioritized their needs by participating in positive self-care behaviours, such as listening to jazz and gospel music and exercising. Prevention and intervention programs that focus on improving caregivers' health should consider the role of self-care practices.
RESUMO
BACKGROUND: A mindfulness-based intervention that reduces comorbid pain, anxiety, and substance use during office-based opioid treatment (OBOT) could enhance retention and prevent overdose. We conducted a pilot study of the Mindful Recovery OUD Care Continuum (M-ROCC), a 24-week trauma-informed program with a motivationally-sensitive curriculum. METHODS: Patients prescribed buprenorphine (N = 18) enrolled in M-ROCC. We collected urine toxicology biweekly. At 0, 4, and 24 weeks, participants completed PROMIS-Pain, PROMIS-Anxiety, Mindfulness (FFMQ), Experiential Avoidance (BEAQ), Interoceptive Awareness (MAIA), and Self-Compassion (SCS-SF) scales. We estimated changes over time using mixed models. Participants completed qualitative interviews at 4 and 24 weeks. RESULTS: Positive urine toxicology decreased over time for cocaine (ß = -.266, p = .008) and benzodiazepines (ß = -.208, p = .028). M-ROCC reduced PROMIS-Pain (Z = -2.29; p = .022), BEAQ (Z = -2.83; p = .0005), and increased FFMQ (Z = 3.51; p < .001), MAIA (Z = 3.40; p = .001), and SCS-SF (Z = 2.29; p = .022). Participants with co-morbid anxiety had decreased PROMIS-Anxiety (Z = -2.53; p = .012). Interviewed participants commonly used mindfulness practices for stress and anxiety (12/12, 100%), and to reduce pain catastrophizing and rumination (7/12, 58%). CONCLUSION AND SCIENTIFIC SIGNIFICANCE: This is the first study to report the effects of a 24-week mindfulness program during buprenorphine treatment on common comorbidities, including pain interference, anxiety, cocaine, and benzodiazepine use. The findings that M-ROCC is associated with reduced experiential avoidance, as well as increased interoceptive awareness and self-compassion, align with proposed mechanisms that are now extended to OUD treatment. Future larger randomized controlled trials are needed before effectiveness can be established and the role of these mechanisms can be confirmed.

Agrobiodiversity-the variation within agricultural plants, animals, and practices-is often suggested as a way to mitigate the negative impacts of climate change on crops [S. A. Wood et al., Trends Ecol. Evol. 30, 531-539 (2015)]. Recently, increasing research and attention has focused on exploiting the intraspecific genetic variation within a crop [Hajjar et al., Agric. Ecosyst. Environ. 123, 261-270 (2008)], despite few relevant tests of how this diversity modifies agricultural forecasts. Here, we quantify how intraspecific diversity, via cultivars, changes global projections of growing areas. We focus on a crop that spans diverse climates, has the necessary records, and is clearly impacted by climate change: winegrapes (predominantly Vitis vinifera subspecies vinifera). We draw on long-term French records to extrapolate globally for 11 cultivars (varieties) with high diversity in a key trait for climate change adaptation-phenology. We compared scenarios where growers shift to more climatically suitable cultivars as the climate warms or do not change cultivars. We find that cultivar diversity more than halved projected losses of current winegrowing areas under a 2 °C warming scenario, decreasing areas lost from 56 to 24%. These benefits are more muted at higher warming scenarios, reducing areas lost by a third at 4 °C (85% versus 58%). Our results support the potential of in situ shifting of cultivars to adapt agriculture to climate change-including in major winegrowing regions-as long as efforts to avoid higher warming scenarios are successful.

Compound extremes such as cooccurring soil drought (low soil moisture) and atmospheric aridity (high vapor pressure deficit) can be disastrous for natural and societal systems. Soil drought and atmospheric aridity are 2 main physiological stressors driving widespread vegetation mortality and reduced terrestrial carbon uptake. Here, we empirically demonstrate that strong negative coupling between soil moisture and vapor pressure deficit occurs globally, indicating high probability of cooccurring soil drought and atmospheric aridity. Using the Global Land Atmosphere Coupling Experiment (GLACE)-CMIP5 experiment, we further show that concurrent soil drought and atmospheric aridity are greatly exacerbated by land-atmosphere feedbacks. The feedback of soil drought on the atmosphere is largely responsible for enabling atmospheric aridity extremes. In addition, the soil moisture-precipitation feedback acts to amplify precipitation and soil moisture deficits in most regions. CMIP5 models further show that the frequency of concurrent soil drought and atmospheric aridity enhanced by land-atmosphere feedbacks is projected to increase in the 21st century. Importantly, land-atmosphere feedbacks will greatly increase the intensity of both soil drought and atmospheric aridity beyond that expected from changes in mean climate alone.

Smoking and substance use during pregnancy are major preventable causes of mortality and morbidity, having a bidirectional and deleterious relationship with the mental health of the mother and child. As part of the WOMAP (Woman Mental Health and Addictions on Pregnancy) initiative, our study aimed to describe the prevalence of co-occurring mental illness and substance use problems, diagnoses and severity of those considered at risk and rates of treatment.A screening of 2,014 pregnant women was done using the AC-OK scale and they were asked about their smoking habits and services use for mental health/substance abuse. Of these, 170 women were considered at risk of co-occurring mental illness and substance use problems (≥ 2 positive responses to the AC-OK-Mental Health subscale, ≥ 1 positive response to the AC-OK-Substance Abuse subscale and/or smoking more than once a month and no use of specialized services) and were assessed with a more extensive battery of measures (Patient Health Questionnaire [PHQ-9], General Anxiety Disorder [GAD-7], Posttraumatic stress disorder [PTSD] Checklist for DSM-5 [PCL-5], Alcohol Use Disorders Identification Test [AUDIT], Drug Abuse Screening Test [DAST] and Fagerström).In the last year, 614 women (30.5%) smoked tobacco (42.5% daily) and 9.8% were positive for both substance use and mental illness per the AC-OK. Only 11.1% of them received specific treatment in the previous three months while another 13.6% were scheduled to attend services in the following month. From the subsample assessed in depth, 62(36.5%) endorsed at least moderate depression, 35(20.6%) endorsed at least moderate anxiety, 32(18.8%) endorsed PTSD on the PCL, and 37 out of 88 alcohol users scored above the threshold in AUDIT (≥ 3). In conclusion, high prevalence and low treatment rates suggest that effective detection mechanisms should be integrated into usual care, allowing for early interventions.
El tabaquismo y el consumo de sustancias durante el embarazo son importantes causas prevenibles de morbimortalidad, teniendo una relación bidireccional y deletérea con la salud mental de la madre y el niño. Como parte de la iniciativa WOMAP (Woman Mental Health and Addictions on Pregnancy), se estudiaron 2.014 embarazadas buscando describir la prevalencia de trastornos mentales y por uso de sustancias concurrentes, las tasas de tratamiento y los diagnósticos y la gravedad. Las participantes fueron evaluadas con la escala AC-OK y se les preguntó sobre sus hábitos tabáquicos y uso de servicios de salud mental/sustancias. De las participantes, 170 mujeres resultaron positivas para un trastorno mental y por uso de sustancias concurrentes (≥ 2 positivos a la subescala AC-OK-Salud Mental, ≥ 1 positivos a la subescala AC-OK-Sustancias y/o fumar más de una vez al mes y no estar en tratamiento) y fueron evaluadas en profundidad mediante una batería de escalas (Patient Health Questionnaire [PHQ-9], General Anxiety Disorder [GAD-7], Post-traumatic stress disorder Checklist [PCL-5], Alcohol Use Disorders Identification Test [AUDIT], Drug Abuse Screening Test [DAST] y Fagerström).En el último año, 614 mujeres (30,5%) fumaron tabaco (42,5% diariamente) y el 9,8% fueron positivas para problemas por uso de sustancias y salud mental según la AC-OK. Solo el 11,1% había recibido tratamiento en los tres meses previos y solo un 13,6% tenía una cita en el siguiente mes. De las 170 pacientes evaluadas secundariamente, 62(36,5%) presentaron al menos depresión moderada, 35(20,6%) al menos ansiedad moderada, 32(18,8%) fueron positivas a la PCL-5, y 37 de las 88 que reconocieron uso de alcohol puntuaron por encima del umbral en AUDIT (≥ 3). En conclusión, la combinación de una prevalencia significativa junto con bajas tasas de tratamiento, remarcan la necesidad de mecanismos de detección efectivos en la atención habitual, permitiendo una intervención temprana.

Temperate forests are shaped by late spring freezes after budburst - false springs - which may shift with climate change. Research to date has generated conflicting results, potentially because few studies focus on the multiple underlying drivers of false spring risk. Here, we assessed the effects of mean spring temperature, distance from the coast, elevation and the North Atlantic Oscillation (NAO) using PEP725 leafout data for six tree species across 11 648 sites in Europe, to determine which were the strongest predictors of false spring risk and how these predictors shifted with climate change. All predictors influenced false spring risk before recent warming, but their effects have shifted in both magnitude and direction with warming. These shifts have potentially magnified the variation in false spring risk among species with an increase in risk for early-leafout species (i.e. Aesculus hippocastanum, Alnus glutinosa, Betula pendula) compared with a decline or no change in risk among late-leafout species (i.e. Fagus sylvatica, Fraxinus excelsior, Quercus robur). Our results show how climate change has reshaped the drivers of false spring risk, complicating forecasts of future false springs, and potentially reshaping plant community dynamics given uneven shifts in risk across species.

BACKGROUND: Physicians often receive lower payments for dual-eligible Medicare-Medicaid beneficiaries versus nondual Medicare beneficiaries because of state reimbursement caps. The Affordable Care Act (ACA) primary care fee bump temporarily eliminated this differential in 2013-2014. OBJECTIVE: To examine how dual payment policy impacts primary care physicians' (PCP) acceptance of duals. RESEARCH DESIGN: We assessed differences in the likelihood that PCPs had dual caseloads of ≥10% or 20% in states with lower versus full dual reimbursement using linear probability models adjusted for physician and area-level traits. Using a triple-difference approach, we examined changes in dual caseloads for PCPs versus a control group of specialists in states with fee bumps versus no change during years postbump versus prebump. SUBJECTS: PCPs and specialists (cardiologists, orthopedic surgeons, general surgeons) that billed fee-for-service Medicare. MEASURES: State dual payment policies and physicians' dual caseloads as a percentage of their Medicare patients. RESULTS: In 2012, 81% of PCPs had dual caseloads of ≥10% and this was less likely among PCPs in states with lower versus full dual reimbursement (eg, difference=-4.52 percentage points; 95% confidence interval, -6.80 to -2.25). The proportion of PCPs with dual caseloads of ≥10% or 20% decreased significantly between 2012 and 2017 and the fee bump was not consistently associated with increases in dual caseloads. CONCLUSIONS: Pre-ACA, PCPs' participation in the dual program appeared to be lower in states with lower reimbursement for duals. Despite the ACA fee bump, dual caseloads declined over time, raising concerns of worsening access to care.

Predicting how increasing atmospheric CO2 will affect the hydrologic cycle is of utmost importance for a range of applications ranging from ecological services to human life and activities. A typical perspective is that hydrologic change is driven by precipitation and radiation changes due to climate change, and that the land surface will adjust. Using Earth system models with decoupled surface (vegetation physiology) and atmospheric (radiative) CO2 responses, we here show that the CO2 physiological response has a dominant role in evapotranspiration and evaporative fraction changes and has a major effect on long-term runoff compared with radiative or precipitation changes due to increased atmospheric CO2 This major effect is true for most hydrological stress variables over the largest fraction of the globe, except for soil moisture, which exhibits a more nonlinear response. This highlights the key role of vegetation in controlling future terrestrial hydrologic response and emphasizes that the carbon and water cycles are intimately coupled over land.

The ubiquitin (Ub) proteolysis pathway uses an E1, E2, and E3 enzyme cascade to label substrate proteins with ubiquitin and target them for degradation. The mechanisms of ubiquitin chain formation remain unclear and include a sequential addition model, in which polyubiquitin chains are built unit by unit on the substrate, or a preassembly model, in which polyubiquitin chains are preformed on the E2 or E3 enzyme and then transferred in one step to the substrate. The E2 conjugating enzyme UBE2K has a 150-residue catalytic core domain and a C-terminal ubiquitin-associated (UBA) domain. Polyubiquitin chains anchored to the catalytic cysteine and free in solution are formed by UBE2K supporting a preassembly model. To study how UBE2K might assemble polyubiquitin chains, we synthesized UBE2K-Ub and UBE2K-Ub2 covalent complexes and analyzed E2 interactions with the covalently attached Ub and Ub2 moieties using NMR spectroscopy. The UBE2K-Ub complex exists in multiple conformations, including the catalytically competent closed state independent of the UBA domain. In contrast, the UBE2K-Ub2 complex takes on a more extended conformation directed by interactions between the classic I44 hydrophobic face of the distal Ub and the conserved MGF hydrophobic patch of the UBA domain. Our results indicate there are distinct differences between the UBE2K-Ub and UBE2K-Ub2 complexes and show how the UBA domain can alter the position of a polyubiquitin chain attached to the UBE2K active site. These observations provide structural insights into the unique Ub chain-building capacity for UBE2K.

Few studies have examined the association between maternal and youth mental health among US Latinos, or its variation by nativity, country of origin, ethnic subgroup, and time in the mainland US. Using 2007-2014 Medical Expenditure Panel Survey data linking Latino youth (N = 15,686 aged 5-17 years) and their mothers, we estimated multivariate models of the relationship between probable maternal mental illness (a composite of measures) and youth mental health impairment (Columbia Impairment Scale). Children of mothers with probable mental illness were more than three times as likely to have impairment as children of mothers without mental illness (p < 0.01). In adjusted models, there was an 8.5-point (95% CI 5.1, 11.8) increased prevalence of child impairment associated with mother's probable mental illness among mainland US-born youth and mothers and a 6.0-point (95% CI 3.7, 8.3) increased prevalence among US-born youth of foreign/island-born mothers. There was no significant difference in the prevalence of youth impairment associated with maternal mental illness when both youth and mother were born outside of the mainland US. For the Puerto Rican subgroup, the association between maternal and youth mental health was greatest among island-born mothers and mainland US-born youth; for the Mexican subgroup, the link was strongest among US-born mothers and youth. While there were large point differences between those groups, the difference was not statistically significant. This study suggests a protective effect of island/foreign-born nativity on symptom association between Latino mothers and children. Considerations for future research and practice stemming from this finding are discussed.

Objective: The objective of this study is to examine the association of country of residence with body mass index (BMI) between Mexican and Colombian patients exposed to antipsychotics. We hypothesize that there will be a significant association between country of residence and BMI and that Mexican patients will have higher BMI than their Colombian counterparts.Design: The International Study of Latinos on Antipsychotics (ISLA) is a multisite, international, cross sectional study of adult Latino patients exposed to antipsychotics in two Latin American Countries (i.e. Mexico and Colombia). Data were collected from a total of 205 patients (149 from Mexico and 56 from Colombia). The sites in Mexico included outpatient clinics in Mexicali, Monterrey and Tijuana. In Colombia, data were collected from outpatient clinics in Bogotá. For this study we included patients attending outpatient psychiatric community clinics that received at least one antipsychotic (new and old generation) for the last 3 months. A linear regression model was used to determine the association of country of residence with BMI for participants exposed to an antipsychotic.Results: After controlling for demographics, behaviors, biological and comorbid psychiatric variables, there was a significant difference between Colombia vs. Mexico in the BMI of patients exposed to antipsychotics (ß = 4.9; p < 0.05).Conclusion: Our hypotheses were supported. These results suggest that differences in BMI in patients exposed to antipsychotics in Mexico and Colombia may reflect differences in prevalence of overweight/obesity at the population level in the respective countries, and highlights the involvement of other risk factors, which may include genetics.

As a part of a larger, mixed-methods research study, we conducted semi-structured interviews with 21 adults with depressive symptoms to understand the role that past health care discrimination plays in shaping help-seeking for depression treatment and receiving preferred treatment modalities. We recruited to achieve heterogeneity of racial/ethnic backgrounds and history of health care discrimination in our participant sample. Participants were Hispanic/Latino (n = 4), non-Hispanic/Latino Black (n = 8), or non-Hispanic/Latino White (n = 9). Twelve reported health care discrimination due to race/ethnicity, language, perceived social class, and/or mental health diagnosis. Health care discrimination exacerbated barriers to initiating and continuing depression treatment among patients from diverse backgrounds or with stigmatized mental health conditions. Treatment preferences emerged as fluid and shaped by shared decisions made within a trustworthy patient-provider relationship. However, patients who had experienced health care discrimination faced greater challenges to forming trusting relationships with providers and thus engaging in shared decision-making processes.

Temperate plants are at risk of being exposed to late spring freezes. These freeze events-often called false springs-are one of the strongest factors determining temperate plants species range limits and can impose high ecological and economic damage. As climate change may alter the prevalence and severity of false springs, our ability to forecast such events has become more critical, and it has led to a growing body of research. Many false spring studies largely simplify the myriad complexities involved in assessing false spring risks and damage. While these studies have helped advance the field and may provide useful estimates at large scales, studies at the individual to community levels must integrate more complexity for accurate predictions of plant damage from late spring freezes. Here, we review current metrics of false spring, and how, when, and where plants are most at risk of freeze damage. We highlight how life stage, functional group, species differences in morphology and phenology, and regional climatic differences contribute to the damage potential of false springs. More studies aimed at understanding relationships among species tolerance and avoidance strategies, climatic regimes, and the environmental cues that underlie spring phenology would improve predictions at all biological levels. An integrated approach to assessing past and future spring freeze damage would provide novel insights into fundamental plant biology and offer more robust predictions as climate change progresses, which are essential for mitigating the adverse ecological and economic effects of false springs.

Hydroclimate extremes in North America, Europe, and the Mediterranean are linked to ocean and atmospheric circulation anomalies in the Atlantic, but the limited length of the instrumental record prevents complete identification and characterization of these patterns of covariability especially at decadal to centennial timescales. Here we analyze the coupled patterns of drought variability on either side of the North Atlantic Ocean basin using independent climate field reconstructions spanning the last millennium in order to detect and attribute epochs of coherent basin-wide moisture anomalies to ocean and atmosphere processes. A leading mode of broad-scale moisture variability is characterized by distinct patterns of North Atlantic atmosphere circulation and sea surface temperatures. We infer a negative phase of the North Atlantic Oscillation and colder Atlantic sea surface temperatures in the middle of the 15th century, coincident with weaker solar irradiance and prior to strong volcanic forcing associated with the early Little Ice Age.
