Remote sensing technologies are integral to monitoring the mountain cryosphere in a warming world. Satellite missions and field-based platforms have transformed understanding of the processes driving changes in mountain glacier dynamics, snow cover, lake evolution, and the associated emergence of hazards (e.g. avalanches, floods, landslides). Sensors and platforms are becoming more bespoke, with innovation being driven by the commercial sector, and image repositories are more frequently open access, leading to the democratisation of data analysis and interpretation. Cloud computing, artificial intelligence, and machine learning are rapidly transforming our ability to handle this exponential increase in data. This review therefore provides a timely opportunity to synthesise current capabilities in remote sensing of the mountain cryosphere. Scientific and commercial applications were critically examined, recognising the technologies that have most advanced the discipline. Low-cost sensors can also be deployed in the field, using microprocessors and telecommunications equipment to connect mountain glaciers to stakeholders for real-time monitoring. The potential for novel automated pipelines that can process vast volumes of data is also discussed, from reimagining historical aerial imagery to produce elevation models, to automatically delineating glacier boundaries. Finally, the applications of these emerging techniques that will benefit scientific research avenues and real-world societal programmes are discussed.

et al. (2 more authors) (2019) Evidence for ecosystem state shifts in Alaskan continuous permafrost peatlands in response to recent warming. Quaternary Science Reviews, 207. pp. 134-144.

High-latitude peatlands are changing rapidly in response to climate change, including permafrost thaw. Here, we reconstruct hydrological conditions since the seventeenth century using testate amoeba data from 103 high-latitude peat archives. We show that 54% of the peatlands have been drying and 32% have been wetting over this period, illustrating the complex ecohydrological dynamics of high latitude peatlands and their highly uncertain responses to a warming climate.

ObjectivesCOVID-19 presented a new risk to the care home sector. Primary care adapted their approach to the management of COVID-19 in care homes as the pandemic evolved. Our aim was to evaluate the clinical presentation, management, care planning and clinical decision-making, and after death care of care home residents who died due to COVID-19 in Aneurin Bevan University Health Board in Southeast Wales.MethodClinical records of 136 in care homes were reviewed by a General Practitioner reviewer using a standardised template. These were then reviewed by a multidisciplinary panel to identify themes.ResultsMost individuals presented with ‘typical’ COVID-19 symptoms (cough, fever); however, >50 presented with atypical symptoms. 90% had a record of Do Not Attempt Cardiopulmonary Resuscitation (DNACPR) decision, but only 46% had documented advance care planning (ACP), and only 37% had a clearly documented treatment escalation plan.ConclusionCare home residents are at risk of sudden clinical deterioration and death. This evaluation demonstrates that although DNACPR is in place for most individuals, holistic planning for end of life (including ACP and clinical care plans covering management of deterioration and escalation of care) is only present for a minority.
