    Structural evolution triggers a dynamic reduction in active glacier length during rapid retreat: evidence from Falljökull, SE Iceland

    Over the past two decades Iceland's glaciers have been undergoing a phase of accelerated retreat set against a backdrop of warmer summers and milder winters. This paper demonstrates how the dynamics of a steep outlet glacier in maritime SE Iceland have changed as it adjusts to recent significant changes in mass balance. Geomorphological evidence from Falljökull, a high-mass turnover temperate glacier, clearly shows that between 1990 and 2004 the ice front was undergoing active retreat resulting in seasonal oscillations of its margin. However, in 2004–2006 this glacier crossed an important dynamic threshold and effectively reduced its active length by abandoning its lower reaches to passive retreat processes. A combination of ice surface structural measurements with radar, lidar, and differential Global Navigation Satellite Systems data are used to show that the upper active section of Falljökull is still flowing forward but has become detached from and is being thrust over its stagnant lower section. The reduction in the active length of Falljökull over the last several years has allowed it to rapidly reequilibrate to regional snowline rise in SE Iceland over the past two decades. It is possible that other steep, mountain glaciers around the world may respond in a similar way to significant changes in their mass balance, rapidly adjusting their active length in response to recent atmospheric warming

    The feasibility of a multi‐professional training to improve how health care professionals deliver different news to families during pregnancy and at birth

    Background: In the United Kingdom, pregnant women are offered foetal anomaly screening to assess the chance of their baby being born with eleven different conditions. How health care professionals (HCPs) deliver news about a child having a congenital anomaly affects how it is received and processed by parents. We refer to this news as different news. Methods: We conducted a mixed methods evaluation of a training intervention to improve how HCPs deliver different news. Twenty‐six HCPs self‐completed pretraining and posttraining questionnaires on skills, knowledge, and attitudes related to delivering different news. Qualitative interviews were conducted with eight HCPs. Quantitative data were analysed using descriptive statistics, the paired t test to compare the pre and post scores and estimate the difference between pre and post scores, and the 95% confidence interval. Qualitative data were analysed using framework analysis guided by the Theoretical Domains Framework (TDF). Results: The training intervention was both feasible and acceptable. HCPs indicated that it enhanced or consolidated their knowledge and skills, covered topics relevant to their practice, and that they would recommend it to colleagues. Participants particularly valued integration of the voice of parents with lived experience in the training. Significant increase in mean scores were observed in confidence to deliver different news (2.81, 95% CI [2.43, 3.19] to 4.28, 95% CI [4.09, 4.47]; p < .001) and skills to deliver different news (3.00, 95% CI [2.64, 3.36] to 4.36, 95% CI [4.13, 4.59]; p < .001). HCPs reported feeling more confident in their ability to provide sensitive, responsive, balanced care to families. Conclusions: The significant improvements in confidence and skills reported by HCPs suggest that the training may be effective in equipping HCPs to minimize the distress, anxiety, and depression associated with receiving different news. This represents a key aspect of the prevention of mental ill health across the life course
